Ontogeny of non-muscular brachial articulations in extant species of Balanocrininae, i.e., Neocrinus decorus, Neocrinus blakei and Hypalocrinus naresianus (Crinoidea, Isocrinida), is described using SEM observations. All three species share embayed synarthries and symplexies (previously only known in crinoid stalks) showing a radiating crenularium pattern in their proximal arms but differ in several important ways. Neocrinus decorus has a shallow simple symmorphy affecting symplexies, and embayed synarthries. During the latest ontogeny of embayed synarthries, irregular syzygial ridges appear on the aboral segment of the fulcral ridge. Neocrinus blakei and H. naresianus share a peculiar sharp deep symmorphy superimposed on symplexies, and synarthries with a more complete single fulcral ridge that only appears late in ontogeny. Comparison with other crinoid taxa that have more advanced arm axial synarthries shows that this ontogenetic trajectory is restricted to paedomorphic stages in extant balanocrinins. An embayed synarthry seems to be derived from the earliest developmental stage of the radiating symplexial crenularium via hypermorphosis of a single crenula. An embayed synarthry is, therefore, a symplesiomorphy based on paedomorphic stage of development; it thus lacks phylogenetic significance, and should be abandoned as a major character in the classification of Isocrinida. The most advanced brachial synarthries shared by distant crinoid taxa mainly represent a homoplasy under morphofunctional constraints. However, they could result from different ontogenetic trajectories, which have only rarely been investigated. Another distinctive articulation feature, the peculiar sharp deep symmorphy observed in extant balanocrinins is a derived character known in a few fossil isocrinids beginning in the Middle Jurassic. We question its phylogenetic significance and suggest that it has developed repeatedly via iterative evolution in Isocrinida. Therefore, because these three extant balanocrinin species share the same ontogenetic trajectories of arm and stalk ligamentary articulations, and differ only in various states of heterochronic development of a few characters, we treat them as belonging to the same genus. We, therefore, consider Hypalocrinus as a junior synonym of the genus Neocrinus.

The family Callanthiidae contains two genera, Grammatonotus (with ten nominal and a few putative species) and Callanthias (the Splendid Perches, with seven species). We provide characters that distinguish callanthiids from other percoids and that distinguish Grammatonotus from Callanthias. Also provided are descriptions of Grammatonotus and its species, a key to the species of Grammatonotus, and comments on other aspects of the biology of Grammatonotus.

The diversity and evolution of the Red Sea invertebrates in mesophotic and deep-water benthic ecosystems remain largely unexplored. The Palaemonidae is a diversified family of caridean shrimps with numerous taxa in need of taxonomic revisions based on recent molecular analyses. The Red Sea mesophotic and bathyal palaemonid shrimps are largely unstudied. During recent expeditions off the Red Sea coast of Saudi Arabia, several palaemonid specimens were collected at a depth range of 88–494 m, spanning the mesophotic and bathyal zones. This material was examined morphologically and genetically to infer phylogenetic relationships among the Red Sea taxa and several other palaemonid genera. The concordant morphological and genetic data led to the description of two new genera and two new species. Moreover, one species was recorded in the Red Sea for the first time, with a new host record, whereas three further deep-water species, which do not occur in the Red Sea, were formally transferred to a different genus. As more exploration efforts are deployed, research on the diversity and evolutionary relationships among marine invertebrates from the Red Sea will further underline the uniqueness of its mesophotic and bathyal fauna.

Deep-sea chirostylid and galatheid crustaceans collected during the "Galathea" Expedition 1950-52, Kei Islands Expedition 1922, and by Th. Mortensen, and others now in the collection of the Zoological Museum, Copenhagen constitute the basis of this paper. They comprise 864 specimens, 105 of which are distributed among 38 species in five genera of Chirostylidae (one in Chirostylus Ortmann, 1982; five in Eumunida Smith, 1883; three in Gastroptychus Caullery, 1896; one in Pseudomunida Haig, 1979; three in Uroptychodes Baba, 2004; and 25 in Uroptychus Henderson, 1888). The remaining 759 specimens belong to Galatheidae, with 94 species in 13 genera, including two new genera (three in gononida Baba & de Saint Laurent, 1996; two in Bathymunida Balss, 1914; one in Enriquea n. gen.; eight in Galathea abricius, 1793; one in Heteronida Baba & de Saint Laurent, 1996; one in Leiogalathea Baba, 1969; 29 in Munida Leach, 1820; 38 in Munidopsis Whiteaves, 1874; six in Paramunida Baba, 1988; two in Phylladiorhynchus Baba, i969; one in Raymunida iviacpherson 22 Machordom, 2000; one in Sadayoshia Baba, 1969; and one in Torbenia n. gen.). Twenty-nine new species are described: one of Gastroptychus, nine of Uroptychus, three of Galathea, five of Munida, 10 of Munidopsis, and one of Torbenia. Three species (two of Munida and one of Raymunida) that have depth records exceeding 200 m, but which in the present collection are available from the continental shelf, are incorporated in this report. Chirostylus ciliatus van Dam, 1933 and Gastroptychus chacei Baba, 1986, are transferred to Uroptychus, Munida leviantennata Baba, 1988 is transferred to Enriquea, as also is Agononida insolita Macpherson, 2004 to Torbenia. Examination of the type material of Munida quinquespinosa Balss, 19 13 reveals that it belongs to Galathea. All species are diagnosed and if new, the holotype is described. In order to clarify the identity of some species, type material and/or comparative material from repositories other than the Copenhagen Museum is included in the report (for Uroptychus latirostris, U. tridentatus, and Munidopsis subsquamosa). Color notes are given when available, and geographic and depth distributions are summarized for the species included in the collection. A list of 580 deep-sea species (161 species in six genera of Chirostylidae and 419 species in 26 genera of Galatheidae) known or supposed to occur at depths exceeding 200 m in the Indo-Pacific, including the Southern Ocean, is provided, along with a key to species of each genus where necessary. For each species, synonymy including reference(s), locality and depth records, and the repository and registration number of the type material are given where possible. Brief comments on vertical and horizontal distributions of species are given for multi-species genera.

The Ranellidae, Bursidae and Personidae from the New Caledonia region (including the Loyalty Islands, the Coral Sea and the New Hebrides Arc) are monographed based on the results of an extensive collecting effort totalling more than 1000 stations. Seventy-three species are recorded, with numerous range extensions. One of the more remarkable aspects of this fauna is the uniquely diverse deep-water tonnoidean assemblage, dominated by species such as Bursa fijiensis, B. latitudo, B. quirihorai, species of Distorsio, Sassia remensa, and less common small personids in the genera Distorsionella and Personopsis. The number of species of New Caledonian Personidae is the highest yet recorded. The Personopsis species are the first modem ones correctly referred to the genus. Revisions are provided of Biplex, Gyrineum, Cyinatium (Gelagna), the Cymatium vespaceum, C. tenuiliratum and Bursa latitudo species groups, of southwest Pacific species of Sassia, and of several Cymatium (Ranularia) and Distorsio species. New genera proposed are Halgyrineum (Ranellidae) and Distorsomina (Personidae). Seven new species are proposed: Biplex bozzettii (from Somalia and southem India), Gyrineum longicaudatum (from the tropical westem Pacific), Cymatium pemiiketi (from Oman), Distorsio parvimpedita, Distorsionella pseudaphera, Personopsis purpurata and P. trigonaperta (all from New Caledonia). The nomenclature of numerous taxa is stabilized by the designation of neotypes and lectotypes for nominal species named by A. Adams & Reeve, Broderip, Deshayes, Dillwyn, Dunker, Fulton, Gmelin, Gould, Gray, Iredale, Jousseaume, Kuenen. Küster, Lamarck, Linné, Martin.

Shell, radular, opercular and external anatomical characters are surveyed in world Recent deep-water Cassidae, leading to the recognition of three subfamilies: Cassinae, Oocorythinae and Phaliinae. All Recent species are revised of Galeodea Link, 1807 (=Galeoocorys Kuroda & Habe, 1957), Microsconsia n. gen. and Sconsia Gray, 1847, all included in subfamily Cassinae; of Oocorys Fischer, 1883 (= Benthodolium Verrill & Smith, 1884, = Hadroocorys Quinn, 1980), Eucorys n. gen. (including Oocorys bartschi Rehder, 1943 and O. barbouri Clench & Aguayo, 1939) and Dalium Dall, 1889, all included in subfamily Oocorythinae; and of Echinophoria Sacco, 1890, included in subfamily Phaliinae. New species named are Galeodea plauta n. sp. (northwestern New Zealand), Microsconsia limpusi n. sp. (southeastern Queensland, Australia), and Oocorys grandis n. sp. (central Indian Ocean, and southeastern Atlantic, off Namibia). Galeodea bituminata (Martin, 1933) (based on a Pliocene fossil from Buton Island, Indonesia) is an earlier name for G. echinophorella Habe, 1961; G. carolimartini Beets, 1943 is another earlier name for G. echinophorella. The name usually accepted for the type species of Sconsia, S. striata (Lamarck, 1816), is a junior secondary homonym of S. striata (J. Sowerby, 1812) and the valid name for this species is S. grayi (A. Adams, 1855). Echinophoria kurodai Abbott, 1968 was based on small specimens of E. wyvillei (Watson, 1886), and E. oschei Mühlhäusser, 1992 was based on Indian Ocean specimens of E. wyvillei. Echinophoria carnosa Kuroda & Habe, 1961 is limited to southern Japan to the Philippine Islands.

This paper presents the results from examination and determination of tropical species of Buccinidae from deep water, collected by several expeditions, mainly in the Indo-Pacific area. The material comprises 14 genera and the following new taxa are described : Calliloconcha knudseni (Kermadec Trench, 5480 m), Costaha crosnieri ( S W Indian Ocean, 1740 - 3760 m), Eosipho coriolis (Philippines, 880 m), Eosipho engonia ( SW Indian Ocean, 600 - 1 125 m), Eosipho thorybopus (Mozambique Channel, 400 - 500 m), Kapala bathybius (SE Atlantic, 3550 m), Manaria clandestina (SE Asia, 440-1 490 m), Manaria makassarensis ( S E Asia, 490 - 875 m), Manaria formosa (Mozambique Channel, 400 - 500 m). For the preparation of this paper we have examined material and/or types of almost all previously described deep sea species of tropical buccinids and these are figured and commented on. An appendix lists all Neogene and Recent supraspecific names of Buccinidae proposed after the publication of WENZ' " Handbuch der Palaozoologie " ( 1941 - 43 ).

The shell of Buccinaria, with its synonyms Dotomella and Pionotoma, is characterized by a wide subsutural ramp forming a broad, concave depression, and a short, broad siphonal canal. The general appearance is strongly convergent with shells of certain buccinid genera such as Eosipho. Radula and protoconch morphology confirm a placement of the genus in the family Conidae, subfamily Raphitominae. Buccinaria is known back to Miocene deposits of Europe, prior to the closure of Tethys, and persists only in the Indo-West Pacific. Recent species live on bathyal soft bottoms, where they appear to favour poorly oxygenated reducing sediments. The six species (two new) recognized live at depths between 200 and 1200 m. Buccinaria loochooensis, originally described from Neogene deposits of the Ryukyus, is recorded for the first time in the Recent fauna . Pionotoma teramachii and P. pyrum, two Recent nominal species from Japan, are synonymized with Buccinaria jonkeri and B. martini, respectively, both described from the Neogene of Indonesia. Cominella koperbergi and C. retifera fall within the range of variation of, and are synonymized with, Buccinaria jonkeri.

Based on radular and protoconch morphology, the genus Typhlosyrinx Thiele, 1925 has been successively classified in the subfamily Turriculinae of the family Turridae and in the subfamily Clathurellinae of the family Conidae. It is shown that the protoconch had earlier been misinterpreted, and the presence of a diagonally cancellated sculpture indicates a placement in the conid subfamily Raphitominae. Two conchologically similar genera, based on teleoconch sculpture and radular morphology are recognized: Typhlosyrinx, with axial ribbing on teleoconch spire whorls and a radula with long (250 mum) barbed teeth, and Leiosyrinx n. gen., without axial sculpture and a radula with short (< 100 mum) simplified teeth. Five species (two new) of Typhlosyrinx and four species (all new) of Leiosyrinx are recognized, all at bathyal depths between 280 and 1840 m in the tropical Indo-Pacific and Panamic provinces. The two genera are not known earlier than the Pliocene, where they already occurred in deep-water assemblages.

The Institut de Recherche pour le Développement (IRD, formerly ORSTOM) and Muséum national d’Histoire naturelle (MNHN) launched in the early 1980s a suite of oceanographic expeditions to sample the deep-water benthos of the tropical South and West Pacific, with emphasis on the 100-1,500 m bathymetric zone. This paper reviews the development of this programme to date. It describes the procedures involved in curating the material collected and the involvement of an international network of taxonomic experts to identify, describe and name the molluscan fauna. So far, 1,028 species of molluscs have been recorded from the New Caledonia Exclusive Economic Zone from depths below 100 m, and 601 of these (58.4%) were new species. An additional 142 new species have been described from other South Pacifi c island groups (Solomon Islands, Vanuatu, Fiji, Wallis and Futuna, Tonga, Marquesas Islands and Austral Islands). However, the hyper-diverse families have essentially remained untouched. Regional differences among island groups are high, and New Caledonia, which has been sampled best, shows several discrete areas of micro-endemism. We speculate that the deep-sea mollusc fauna of New Caledonia may amount to 15-20,000 species, and the corresponding number for the whole South Pacifi c may be in the order of 20-30,000 species.

Echinodermata : Pentacrinidae crinoids procured by the MUSORSTOM 2 and CORINDON 2 expeditions. During MUSORSTOM 2 and CORINDON 2 expeditions (West Philippines for the former, Makassar channel for the latter) many stalked crinoids of the family Pentacrinidae were sampled. They are more diversified and comparatively more abundant than the fauna which was collected during the MUSORSTOM 1 expedition. The samplings come from depths between 170 and 970 meters. Four genera are represented : Diplocrinus, Hypalocrinus, Metacrinus and Saracrinus. Detailed descriptions of the ten following species are given : D. alternicirrus, D. sibogae, H. naresianus, M. interruptus, M. musorstomae, M. nodosus, M. serratus, M. wyvillii, S. angulatus and S. superbus. For each specimen, data on morphological features, biometry, arm branching and ossicle articulations are given. Stalk and arm joints were observed under, scanning electron microscope, especially stem synostosis with regard to their importance for taxonorny. Sometimes, some peculiar growth patterns appear to be a consequence of fast regeneration. Such features are illustrated by the proximal part of the stalk of a few specimens belonging to S. angulatus and M. wyvillii. As numerous individuals of each species were collected, it was possible to study the variation of crown and stem characters. The morphological features and their variability seem to be depth related. The bathymetrical distribution of Pentacrinidae in the Western Pacific province is examined and discussed. Intraspecific polymorphism with regard to external stem morphology and arm organization is suggested for a few species of this biogeographical province. The number of recognized species might be reduced because sorne of them might be interpreted as a consequence of ecophenotypic or geographical variations. So, in the subfamily Metacrininae, S. acutus, S. cingulatus, S. batheri and S. suluensis might be synonyms of S. angulatus. It is also suggested that S. nobilis (S. varians and S. superbus included) shows intraspecific polymorphism or large morphological variations through a wide depth range. For the genus Metacrinus, simplification of the species number is more difficult to effect because each phenotype frequently seems to be clearly distinguished. Nevertheless, M. interruptus and M. musorstomae are very similar and the latter might be an ecophenotype of the former. M. costatus and M. serratus are also two species with large morphological affinities; the first species seems to be a morph living in deeper environment. M. rotundus might include M. multisegmentatus and M. cyaneus. Stem and arm morphological variations linked to bathymetry are also interpreted in terms of adaptative strategy (r and K selection). For pentacrinids, two unstability limits are suggested from their depth repartition : the upper boundary (about 100 meters) couId correspond to hydrodynamic vulnerability threshold, the lower (about 1500-2500 meters) to the trophic vulnerability limit, the food becoming too scarce. In one genus, species living close to these two unstability limits have a very important morphological variability (for example : M. rotundus, M. wyvillii). In the Western Pacifie, the most stable depth range for these crinoids could be situated between 300 and 600 meters with development of K strategy (M. serratus). Biogeographical repartition of these species is analysed from such a point ofview. Typical r strategy species (M. rotundus, M. wyvillii, S. nobilis, H. naresianus) have the largest geographical repartition. S. nobilis seems to be the species with the most eurybathic pattern with polymorphie characters. Taxonomy, paleoecology and biostratigraphy of fossil stalked crinoids must be reconsidered and discussed as a consequence of these results.

Several French oceanographic expeditions have enhanced the exploration of the bathyal slope, off New Caledonia (South Western Pacific). During these recent cruises (BIOCAL, BIOGEOCAL, MUSORSTOM 4-6, CHALCAL 2, SMIB 3-4, CALSUB), many stalked Crinoids of different orders and suborders (Isocrinida Pentacrinidae, Millericrinina, Bourgueticrinina, Cyrtocrinida and incertae sedis) have been sampled, or observed and photographed with the help of the IFREMER submersible « Cyana ». The samples come from depths between 230 and 3700 meters but the most numerous faunas have been gathered in the 200-600 meters bathymetrical interval. Fourteen genera are represented in the crinoid fauna of New Caledonia which have never been inventoried or illustrated : Metacrinus, Saracrinus, Diplocrinus, Proisocrinus, Caledonicrinus, Porphyrocrinus, Naumachocrinus, Bathycrinus, Gymnocrinus, Holopus, Proeudesicrinus, Thalassocrinus, Hyocrinus, Guillecrinus. Some of these are only known from the New Caledonian bathyal slope ( Caledonicrinus, Proeudesicrinus). Until now the genus Holopus was known only from the Tropical Western Atlantic Ocean and the genus Guillecrinus was known only from the bathyal slope of the Indian Ocean. Detailed descriptions of sixteen species are given. Three taxa are illustrated for the first time : Holopus alidis sp. Nov., Guillecrinus neocaledonicus sp. Nov. And Hyocrinus cyanae sp. Nov. Further descriptions are supplied for some species (Naumachocrinus hawaiiensis, Gymnocrinus richeri) and for three recently described new taxa from New Caledonia off shore (Metacrinus levii, Caledonicrinus vauhani, Proeudesicrinus lifouensis). The New Caledonian Pentacrinid fauna is abundant but ess diverse than the rich fauna which has been collected off the Philippines (Western Pacific). Only four species are known from New Caledonia : Metacrinus levii. Metacrinus musorstomae, Saracrinus nohilis, Diplocrinus allernicirrus. Cyrtocrinida are very numerous between 300-500 meters, especially Gymnocrinus richeri and Holopus alidis. This bathymetrical interval is also occupied by Caledonicrinus vauhani. The shallower species of the deep-sea family Bathycrinidae and by Porphyrocrinus. Proisocrinus ruberrimus. Naumachocrinus hawaiiensis. Bathycrinus. Hyocrinidac with Hyocrinus, Thalassocrinus and the incertae sedis Guillecrinus neocaledonicus are living in the deep sea (below 1000 meters). Nevertheless, the New Caledonian stalked Crinoid fauna appears to be the most archaic in the recent oceans showing a close relationship with the fossil fauna of the Mesozoic Mesogean Sea. Many taxa have indeed very ancient affinities : Guillecrinus is the only living representative of the Paleozoic subclass Inadunata. Proisocrinus ruberrimus. Gymnocrinus richeri and Proeudesicrinus lifouensis have relationships with Jurassic adaptative radiation, Caledonicrinus vauhani is the most archaic (late Cretaceous affinities) species of the deep-sea family Bathycrinidae. Consequently, historical biogeography and phylogeny of the Indo-Pacific stalked Crinoids, through Post-Paleozoic times, are discussed with regard on the origin of New Caledonia fauna.

This study adds 8 bopyrids to the 5 species previously known from Taiwan. None of the species are new to science, but all are new to the Taiwanese fauna. All of the hosts for the 8 species are new. Four species redescribed herein, Pseudione retrorsa Richardson, Parioninella obovata Shiino, Parapenaeon tertium Nierstrasz and Brender 6 Brandis, and Bopyrus stebbingi Nierstrasz and Brender Brandis, are reported for the 1st time since their original descriptions, with each representing a substantial range extension. The geographic and depth distributions of 2 additional species, Bopyroides hippolytes (Kroyer) and Athelges takanoshimensis Ishii, are greatly extended. Two new genera are erected for P. obovata and B. stebbingi. Pseudione lenticeps Shiino is synonymized with P. retrorsa, which is transferred to the genus Aporobopyrus Nobili. Parapenaeon coarctatum tuberculata is raised to the level of full species. Identifications of hosts as cited in older literature are updated to current nomenclature.

Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders Polychelida, Glypheidea, Astacidea andAchelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and “living fossil” species. The high degree of morphological diversity among these infraorders has led to a dynamic classification and conflicting hypotheses of evolutionary relationships. In this study, we estimated phylogenetic relationships among the major groups of all lobster families and 94% of the genera using six genes (mitochondrial and nuclear) and 195 morphological characters across 173 species of lobsters for the most comprehensive sampling to date. Lobsters were recovered as a non-monophyletic assemblage in the combined (molecular + morphology) analysis. All families were monophyletic, with the exception of Cambaridae, and 7 of 79 generawere recovered as poly- or paraphyletic. A rich fossil history coupled with dense taxon coverage allowed us to estimate and compare divergence times and origins of major lineages using two drastically different approaches. Age priors were constructed and/or included based on fossil age information or fossil discovery, age, and extant species count data. Results from the two approaches were largely congruent across deep to shallow taxonomic divergences across major lineages. The origin of the first lobster-like decapod (Polychelida) was estimated in the Devonian (∼409–372 Ma) with all infraorders present in the Carboniferous (∼353–318 Ma). Fossil calibration subsampling studies examined the influence of sampling density (number of fossils) and placement (deep, middle, and shallow) on divergence time estimates. Results fromour study suggest including at least 1 fossil per 10 operational taxonomic units (OTUs) in divergence dating analyses.

Two new species of Ancylomenes (Decapoda: Pontoniinae), A. kuboi sp. nov. (Australian northwestern shelf and Vietnam, from 9.2-82 m) and A. okunoi sp. nov., (Australian north-western shelf and the Philippines, from 80-134 m, are described and illustrated. Both are most closely related to A. tosaensis (Kubo, 1951), also found on the Northwest Shelf, and a key for their separation is provided.

The description and comparative characteristic of three vicariated Indo-West Pacific species from the genus Nematocarcinus (N. tenuirostris Bate 1888 and N. pseudocersor Burukovsky, 1990 are previously known; N. alisae Burukovsky s. n. is new) are given. They are distinguished from other known species of the genus by similarity in structure of the distro-ventral organ of the 6th abdominal segment. In these species, spots of the distro-ventral organ are located on an original protuberance forming in the distal quarter of ventral segment surface - blister. The spots are always located in close proximity to each other. These species are primarily distinguished by their rostrum structure.

The genus Paramunida belongs to the family Galatheidae, one of the most species rich families among anomuran decapod crustaceans. In spite of the genus has received substantial taxonomic attention, subtle morphological variations observed in numerous samples suggest the existence of undescribed species. The examination of many specimens collected during recent expeditions and morphological and molecular comparisons with previously described species have revelaled the existence of eleven new lineages. All of them are distinguished by subtle and constant morphological differences, which are in agreement with molecular divergences reported for the mitochondrial markers ND1 and 16S rRNA. Here, we describe and illustrate the new species, providing brief redescriptions for the previously known species, and a dichotomous identification key for all species in the genus.

The genus Paramunida belongs to the family Munididae, one of the most speciose families among anomuran decapod crustaceans. During the PANGLAO 2004, PANGLAO 2005, and AURORA 2007 expeditions in the Philippines, eight species of the genus were collected, including a new record and three new species, namely Paramunida akaina, P. aspera, and P. aurora. These new lineages are distinguished by subtle and constant morphological differences, which are in agreement with molecular evidence from the mitochondrial markers ND1 and 16S. Here, we describe these new species, provide new distribution records, and present phylogenetic relationships within the genus.

Fifty-three species of ahermatypic Scleractinia—about half of the Philippine ahermatypic fauna—belonging to four families and one subfamily are described and illustrated. Five additional species found in adjacent waters just north of the Philippines are also included in the faunistic revision. In order to better evaluate the genus Leptopenus, L. antarcticus, from Antarctica, is also included in this revision as a new species, making a total of 59 species revised. Concurrent with the species revision, higher-level taxa were reanalyzed and revised, resulting in the description of four new genera: Endocyathopora, Thrypticotrochus, Truncatoguynia, and Truncatoflabellum and 17 new species; the formation of 13 new species combinations; and the establishment of two new subgeneric ranks: Fungiacyathus (Bathyactis) and Flabellum (Ulocyathus). To help stabilize the nomenclature of taxonomically confusing species, neotypes were designated for two species: Flabellum (= Truncatoflabellum) cumingii and Flabellum (= Truncatoflabellum) candeanum; and lectotypes were chosen for four other species: Bathyactis (= Fungiacyathus) sibogae, Flabellum pavoninum, Flabellum distinctum, and Flabellum patens. Approximately 4400 specimens were examined from 178 stations throughout the Philippines, as well as most of the previously reported specimens from this area. A historical resume is given of previous literature on ahermatypic Scleractinia in the Philippine Islands. Character tables or keys are provided for the genera of Micrabaciidae, Turbinoliinae, Guyniidae, and Flabellidae, and character tables are provided for the Philippine species of Fungiacyathus, Stephanophyllia, Flabellum (Flabellum), and Truncatoflabellum. The Philippine Islands and Indonesia, especially the Sulu Sea, are considered to be at or near the center of ahermatypic species diversity and thus represent the most diverse ahermatypic fauna in the world. East and west of the Philippines the number of species held in common falls rapidly, but relatively high percentages of shared species are found to the north: 30%-32% for the South China Sea off Hong Kong, and 36%-38% for off Japan. The highest number of shared species, however, is with Indonesia (25-27 species, 47%-51%), with which the Philippines probably forms a zoogeographic unit Of the 53 species reported from the Philippines, 27 are new records for this island group.

A total of 134 Recent species of azooxanthellate Scleractinia are reported from the Vanuatu (116 species) and Wallis and Futuna (83 species) Archipelagos, all but one being new records for this region of the tropical central Pacific. The newly reported specimens originate primarily from the MUSORSTOM 7 and 8 expeditions, including approximately 4400 specimens from 227 stations, most of these stations from deeper than 100 m. Sixteen new species and one new subspecies are described, and two new combinations are proposed: Asterosmilia gigas and Javania fusca. Tables of comparison are provided for the Indo-Pacific species of Fungiacyathus (Fungiacyathus)-, the Recent Trocliocyalhus (Aplocyathus)\ all species oi Aulocyathus\ all species of spined Deltocyathus\ and the Recent species and subspecies of Antheiniphyllia. To facilitate comparisons of species among these taxa, three additional species having distributions other than the Vanuatu/Wallis and Futuna region are described as new: Deltocyathus corrugalus, Antheiniphyllia inultidentata, and A. inacrolobata. The distribution and bathymétrie ranges of the 134 species known from the Vanuatu/Wallis and Futuna region are tabulated. Within the tropical central Pacific these corals show a strong affinity with those from the ridges and islands north of New Zealand (56 species) and a lesser relationship with the Hawaiian Island fauna (24 species). Other regions in the central Pacific are too poorly known for comparison. Beyond the tropical central Pacific, the Vanuatu/Wallis and Futuna fauna is part of the larger Indo-Polynesian province, sharing 95 (71%) of its species with the tropical western Pacific and 62 species (46%) with the Indian Ocean. Only seven species are found in common with the tropical eastern Pacific and 11 with the Atlantic Ocean. Finally, 43 species from the Vanuatu/Wallis and Futuna Archipelagos are also known from temperate Japan (exclusive of the Ryukyu Islands) and 32 from temperate New Zealand and southern Australia. Examples of commensal/parasitic relationships are reported to occur with petrarcid ascothoracican crustaceans (2 coral hosts) and acrothoracican cirripede crustaceans (8 hosts). The shells of the gastropod Xenophora ("carrier shells") were found to be effective collectors of deep-water corals; a total of 19 coral species were found incorporated into the shells, including three species that were found only on these shells and another five species that were otherwise very rarely collected by conventional means.

Skythrenchelys n.gen. Differs from other myrophine ophichthids in the condition of its gill openings (moderately elongate and below lateral midline), dentition (large, conical and uniserial), posterior nostril (entirely outside mouth), and other characters. Skythrenchelys zabra n.sp., the type species, is described from India, the Philippines, Indonesia and northern Australia; S. lentiginosa n.sp. Is described from the Red Sea. Scolecenchelys Ogilby, previously a subgenus of Muraenichthys Bleeker, is generically distinct on the basis of differences in dentition (teeth conical and uniserial or biserial vs blunt and multiserial), cephalic pores (2 pores between anterior and posterior nostrils vs 1 pore), and its posterior nostril condition (within vs outside mouth). Valid species of Muraenichthys and Scolecenchelys and their synonyms are identified.

The taxonomy of the crabs belonging to the family Palicidae Bouvier, 1898 from the Indo-west Pacific region is revised. On the basis of extensive material collected by French expeditions in the Coral Sea and other regions of the Pacific and Indian oceans, as well as material from numerous museums, including most of the types, the present study recognizes two subfamilies, 10 genera, and 43 species. Of these taxa, four are new genera: Exopalicus, Miropalicus, Paliculus, and Rectopalicus. Manella is synonymized with Crossotonotus A. Milne Edwards, 1873. Parapleurophricoides Nobili, 1906, sometimes believed to be a palicid, is a xanthoid and it is removed from the Palicidae. Nine nominal species described by previous authors are synonymized and an additional 17 species are described.

The shallow-water trapeziid and tetraliid crabs, symbionts of corals and other colonial anthozoans, from the Philippines, New Guinea, and Vanuatu are listed. A total of 13 species of Trapeziidae and six species of Tetraliidae (two new records) are listed for the Philippines, 15 Trapeziidae (four new records), six Tetraliidae (three new records) for New Guinea, and 12 Trapeziidae (six new records), four Tetraliidae (three new records) for Vanuatu. The number of species in these locations. when compared with the number in adjacent areas, does not support the view that the Indo-Malayan region or the Indo-Australian Archipelago have served as a centre of diversification for these two families.

The family Euryplacidae Stimpson, 1871, traditionally included in the Goneplacidae MacLeay, 1838, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of 31 species (including five that are described as new) belonging to 13 genera (including four that are described as new): Eucrate De Haan, 1835, with eight species, of which one is new; Euryplax Stimpson, 1859, with two species; Frevillea A. Milne-Edwards, 1880, with three species; Henicoplax n. gen., with five species of which three are new; Heteroplax Stimpson, 1858, monotypic; Machaerus Leach, 1818, with two species; Nancyplax Lemaitre, Garcia-Gomez, von Sternberg & Campos, 2001, monotypic; Platyozius Borradaile, 1902, monotypic; Psopheticoides Sakai, 1969, monotypic; Systroplax n. gen., monotypic; Trissoplax n. gen., with two species, of which one is new; Trizocarcinus Rathbun, 1914, with two species; Villoplax n. gen., monotypic; and Xenocrate Ng & Castro, 2007, monotypic. The genus Platyozius and Eucrate formosensis Sakai, 1974, are removed from the synonymy of Eucrate and E. alcocki Serene, in Serene & Lohavanijaya, 1973, respectively. Neotypes are selected for Heteroplax dentata Stimpson, 1858, and Pilumnoplax sulcatifrons Stimpson, 1858, two species described from Hong Kong that have a confusing taxonomic history. A neotype is also selected for Euryplax nitida Stimpson, 1859, described from the Florida Keys. Seven nominal species described by other authors were found to be junior subjective synonyms for other species: Eucrate affinis Haswell, 1882, E. costata Yang & Sun 1979, E. haswelli Campbell 1969, and Pseudorhombila sulcatifrons var. australiensis Miers, 1884, of Trissoplax dentata (Stimpson, 1858); Galene laevimanus (Lucas, in Jacquinot & Lucas, 1853) of Eucrate dorsalis (White, 1849); Heteroplax nagasakiensis Sakai, 1934, of H. transversa Stimpson, 1858; and Pilumnoplax sulcatifrons Stimpson, 1858, of Eucrate crenata (De Haan, 1835). Eight euryplacid genera are exclusively found in the Indo-West Pacific region (except one species introduced in the Mediterranean), one is exclusive to each the Eastern Atlantic and Tropical Eastern Pacific regions, three to the Western Atlantic region, and one genus has both Western Atlantic and Tropical Eastern Pacific species.

A reappraisal of the taxonomy of the brachyuran crabs belonging to the family Goneplacidae MacLeay, 1838 sensu lato has resulted in the revision of the subfamily Goneplacinae, which combines the subfamilies Goneplacinae MacLeay, 1838 and Carcinoplacinae H. Milne Edwards, 1852. Most of the 66 species of Goneplacinae sensu stricto that are listed herein inhabit relatively deep water and are infrequently collected. The subfamily Goneplacinae sensu stricto now consists of 17 genera of which 10 are being described as new: Carcinoplax H. Milne Edwards, 1852, with 18 species of which four are new; Entricoplax n. gen., monotypic; Exopheticus n. gen., with two species; Goneplacoides n. gen., monotypic; Goneplax Leach, 1814, with four species; Hadroplax n. gen., monotypic; Menoplax n. gen., monotypic; Microgoneplax n. gen., with five species of which four are new; Neogoneplax n. gen., with three species of which two are new; Neommatocarcinus Takeda & Miyake, 1969, monotypic; Notonyx A. Milne-Edwards, 1873, with three species; Ommatocarcinus White, 1852, with four species; Paragoneplax n. gen., monotypic; Psopheticus Wood-Mason, 1892, with four species; Pycnoplax n. gen., with five species of which one is new; Singhaplax Serene & Soh, 1976, with seven species of which four are new; and Thyraplax n. gen., with five species of which three are new. All goneplacine genera are exclusive to the Indo-West Pacific region (plus contiguous temperate areas) except Goneplax, which is so far known mostly from the Atlantic and Mediterranean regions. Four nominal species described by other authors were found to be junior subjective synonyms for other species: Carcinoplax verdensis Rathbun, 1914 and C polita Guinot, 1989 synonymous of C specularis Rathbun, 1914; Goneplax megalops Komatsu & Takeda, 2003 of Goneplacoides marivenae (Komatsu & Takeda, 2003) n. comb.; and Psopheticus insolitus Guinot, 1990 of P stridulans Wood-Mason, 1892.

The species of Pontocaris Bate, 1888, and related genera, Aegaeon Agassiz, 1846 and Parapontocaris Alcock, 1901, are reviewed based on the abundant samples collected by ORSTOM (Institut français de Recherche scientifique pour le Développement en Coopération), the Muséum national d'Histoire naturelle, the Forschungsinstitut Senckenberg, and the National Taiwan Ocean University, as well as those deposited at other museums and institutions. Altogether 21 species and one subspecies are recognized which appear to form three natural groups. The genus Parapontocaris Alcock, 1901 is retained for the 6 species assigned to it by CHACE (1984), but different characters are used to differentiate them. An interlocking mechanism between the posterior thoracic sternites and the carapace is found in all species of the Pontocaris propensalata group, but not in the others. Furthermore, females of this group can modify their pereiopods, probably for the care of the eggs, when they molt for spawning. Such modification of the pereiopods is unique in the carideans according to present knowledge. Thus, the genus Pontocaris Bate, 1888, is now restricted to the species of this group and BRUCE'S (1988) Pontocheras becomes a junior synonym of the former. At present 10 species and one subspecies are recognized in this group, with the names P. affinis (Alcock, 1901) and P. hilarula (de Man, 1918) revived and four new species and one new subspecies described : P. major from the Philippines, P. laurentae and P. spinifera from Indonesia, P. profundior from the Red Sea and Gulf of Aden, and P. affinis allodactylus from the Red Sea. The name Aegaeon Agassiz, 1846 is revived for five species with characters intermediate between Parapontocaris and Pontocaris (as defined here), namely A. cataphractus (Olivi, 1792), A. lacazei (Gourret, 1887), A. orientalis Henderson, 1893, A. rathbuni de Man, 1918 and A. boschii (Christoffersen, 1988). Keys for distinguishing these three genera and the identification of the species are provided. The distribution and evolution, as well as sexual dimorphism and polymorphism in females, of these species are briefly discussed. Both the morphological characters and distribution patterns suggest that the genus Parapontocaris is relatively more ancient and has a typical Tethys distribution. On the other hand, species of Pontocaris possess many advanced characters and are still actively evolving in the Indo-West Pacific. The intermediate genus Aegaeon probably forms a link between the above two genera and has successfully invaded the Atlantic from the original Indo-West Pacific distribution.

Samples collected by ORSTOM (Institut de Recherche Scientifique pour le Developpement en Cooperation), Service Mixte de Contrôle Biologique des Armees (SMCB) and the National Taiwan Ocean University in the Indo-West Pacific (off Madagascar, Seychelles Islands, Taiwan, Philippines, Indonesia, Chesterfield Islands, New Caledonia and Polynesia) as well as others obtained on loan from various museums led to a reexamination of the species belonging to the Plesionika narval group. Fourteen species are recognized of which 6 are new : P. yui from Taiwan, P. echinicola from New Caledonia, P. laurentae from New Caledonia and Eastern Australia, P. flavicauda from New Caledonia and Polynesia, P. rubrior and P. curvata from Polynesia. P. escalilis (Stimpson, 1860) is considered to be a synonym of P. narval. The specimens from the Atlantic identified as STIMPSON'S species by LEMAITRE and GORE (1988) are identified as P. longicauda (Rathbun, 1901). P. narval and P. serratifrons (Borradaile, 1900) are considered as distinct species but so similar that finding reliable characters to separate them is very difficult especially as individual variations are observed. P. narval is presently regarded as living only in the Mediterranean and Eastern Atlantic (from Spain to Cape Verde Islands) but it appears South-West Pacific and with a rather restricted distribution. A key mainly for adults is offered for the identification of the species of this group. As coloration very often seems to be a reliable character for identifying fresh specimens, color photographs are included. Unfortunately it was not possible to obtain information on the coloration of all the species and consequently this character could only be used rarely in the key.

Recent French deep-sea expeditions in the Indo-West Pacific resulted in the collection of abundant material of the deep-sea lobster genus Puerulus Ortmann, 1897 (Palinuridae). Difficulties in identification necessitated a generic revision and as a result, five new species are described, all of which are similar to P. angulatus (Bate, 1888). Puerulus angulatus was thought to have a wide distribution from eastern Africa to Marquesas Islands, but is now restricted to the western Pacific, from Japan to Australia. Of the five new species, P. gibbosus n. sp. is found in eastern Africa, P. mesodontus n. sp. from Japan to Fiji, P. richeri n. sp. from the New Caledonia to Marquesas Islands, while P. sericus n. sp. and P. quadridentis n. sp. mainly occur around New Caledonia. Of the other three previously described species, the distribution of P. velutinus Holthuis, 1963, is extended to Fiji, while P. sewelli Ramadan, 1938, and P. carinatus Borradaile, 1910, are still only known from the northern and western parts of the Indian Ocean, respectively. COI gene sequence differences support the morphological species distinctions.

The Oxfordian fauna from the Terrain à Chailles Formation, eastern France (Haute- Saône, Franche-Comté) is remarkable for its exceptionally preserved crustaceans found in siliceous concretions locally named “chailles”. The crustacean fauna includes 9 different species assigned to the Glypheidae, the Erymidae, the Eryonidae and the Axiidae. Glypheid and erymid lobsters are the most diversified groups with four and three different species respectively. Re-examination of numerous new specimens allows to a more modern and more complete characterization of Glyphea regleyana (Desmarest, 1822), Glyphea muensteri von Meyer, 1840 and Eryma ventrosa (von Meyer, 1835). New detailed anatomic descriptions of these species highlight the presence of marked sexual dimorphism in G. regleyana and probably in E. ventrosa. They reveal processes of autotomy and phenomena of ecdysis in G. regleyana, E. ventrosa and G. muensteri. Quantitative analyses based on 424 nodules show three dominant species: 1) Glyphea regleyana (50.5% of nodules); 2) Eryma ventrosa (24.8%); and 3) Glyphea muensteri (16.5%).Convergent lines of evidence from depositional environment, comparisons with others Jurassic crustaceans and modern analogues indicate that the crustacean fauna from the Terrain à Chailles Formation probably inhabited a moderately deep water setting most probably about 100-150 m (lower circalittoral zone) where light intensity was even sensitive. These crustaceans constitute a very original assemblage intermediary between the communities from the shallow carbonate platforms (e.g., Solnhofen) and those from the bathyal zone (e.g., La Voulte). This new set of data sheds new light on the colonization of the distal platforms by crustacean communities in the Mesozoic.

A phylogenetic analysis of a total of 31 species: 27 fossil species from seven families (Glypheidae, Litogastridae, Mecochiridae, Pemphicidae, Erymidae, Clytiopsidae, Chimaerastacidae), and four extant species from three families (Glypheidae, Nephropidae, Stenopodidae) is proposed. Most of the genera considered are coded exclusively based upon their type species and, as much as possible, based upon the type specimens. The cladistic analysis demonstrates that the glypheidean lobsters (infraorder Glypheidea) form a monophyletic group including two superfamilies: Glypheoidea and Pemphicoidea new status. Glypheoidea includes three families: Glypheidae, Mecochiridae and Litogastridae. Litogastridae is the sister group of the clade Glypheidae + Mecochiridae. Pemphicoidea includes a single family: Pemphicidae. A new classification of Glypheidea is proposed and currently known genera are rearranged based upon the phylogenetic analysis.

The eumedonid genera Eumedonus H. Milne Edwards, 1834 and Gonatonotus White, 1847, are revised. Members of both genera are obligate symbionts with sea urchins. Eumedonus is separated from Gonatonotus mainly by the presence or absence of crests on the merus of the ambulatory legs. Eumedonus , as here defined, contains five species, viz. E. niger H. Milne Edwards, 1834 ( type species), E. vicinus Rathbun, 1918, E. zebra Alcock, 1895, E. brevirhynchus n. sp., and E. intermedius n. sp. Gonatonotus, as here re-diagnosed, includes three species, viz. G. pentagonus White, 1847 ( type species), G. granulosus (MacGilchrist, 1905), n. comb. And G. nasutus n. sp.

Numerous samples of Stylodactylidae collected between 1976 and 1989 off the Philippines, New Caledonia and Chesterfield Islands (MUSORSTOM, BIOCAL, CHALCAL, CORAIL 2 a n d SMIB cruises) are studied here. Other collections from Indonesia (CORINDON 2 cruise), Madagascar (coll. A. CROSNIER and R. CLEVA), and la Réunion (« MARION DUFRESNE », cruise M D 32) are included. This material is of particular interest since many specimens of various taxa have been collected : eighteen species and subspecies have been identified in it, of which nine are new : three species and one subspecies in the genus Stylodactylus. four species in the genus Parastylodactylus, and one in the new genus Stylodactyloides. Nine species and one subspecies of the genus Stylodactylus A. Milne Edwards, 1881., are represented in the collections studied here. S. laurentae sp. nov., with its typically short rostrum, seems to be one of the most common shrimps of the genus in New Caledonia and Chesterfield Islands. S. profundus sp. nov., unfortunately represented by specimens in incomplete or poor condition, extends the bathymetric range of the family : it has been collected, off New Caledonia, between 1395-1410 and 1618-1740 m. S. brevidactylus sp. nov. is represented by a single specimen from the Philippines : we at first considered that this specimen was an aberrant example of S. multidentatus Kubo, 1942, but decided then to re-examine our opinion because of its peculiar characters. Twenty seven specimens (eleven from the Philippines and sixteen from Chesterfield Islands and New Caledonia) have been identified as S. licinus Chace, 1983, a little known species described from the Philippines, and eleven others (one from Indonesia and ten from New Caledonia and Chesterfield Islands) as S. tokarensis Zarenkov, 1968, only known by the holotype collected in the east China sea (the paratype of S. tokarensis is suspected of being a specimen of S. licinus Chace). S. multidentatus Kubo, 1942, is probably one of the most commonly caught species of the family. Many specimens have been collected by the french campaigns from the Philippines, New Caledonia, and Madagascar : Neocaledonian specimens differ from the former by a longer rostrum and longer spines on the margin of the antennal scale. These differences are still more accentuated in Madagascarian specimens, and we finally decided to create for them a new subspecies, S. multidentatus robustus. Two other species of Stylodactylus are represented in our material : S. macropus Chace, 1983, of which the only previouly known specimen was collected by the « ALBATROSS » in the Philippines, is reported here, again from the Philippines and from New Caledonia and Chesterfield Islands. S. libratus Chace, 1983, described from a single specimen from Indonesia (Celebes, « ALBATROSS » collection) and reported then from Australia (New South Wales) by KENSLEY, TRANTER and GRIFFIN (1987) has been collected in New Caledonia and Chesterfield Islands. One specimen from Madagascar appears to be very close to S. libratus but shows however some différences from it, so that we identify it as S. aff. libratus. The genus Neostylodactylus Hayashi & Miyake, 1968, is represented in our material by two species : N. amarynthis (de Man, 1902), and N. affinis Hayashi & Miyake, 1968 : in these two species we have noted the very particular sexual dimorphism mentioned by CHACE (1983 : 6) for N. amarynthis : females differ from maies in lacking arthrobranchs on pereiopods 1 to 4. The geographical distribution of N. amarynthis extends now, in the Indo-Pacific, to the southwestern Indian Océan (La Réunion), and that of N. affinis, previously known only from the Korea Strait at 120 m depth, is shown to belong to the New Caledonia and Chesterfield Islands fauna ; it has been caught between 235 and 440 m. Four new species have been included in the genus Parastylodactylus created by FIGUEIRA in 1971 for Stylodactylus bimaxillaris Bate, 1888, and until now monospecific. P. bimaxillaris (Bate), known from a large part of the Indo-Pacific, is mentioned for the first time from New Caledonia and Madagascar. P. tranterae sp. nov., collected off New Caledonia and Chesterfield Islands, was first reported from Australia (New South Wales) by KENSLEY, TRANTER a n d GRIFFIN (1987) who suspected that it was a new species, butdid not name it, on account of the poor condition of the single specimen in their possession. P. semblatae sp. nov. seems to be very common in New Caledonia and Chesterfield Islands. P. richeri sp. nov., from New Caledonia, and P. longidactylus sp. nov., from the Philippines, each represented by a few specimens only, are fairly closely related species, but however are clearly distinct taxa. A new genus, Stylodactyloides, is proposed for a new species collected from New Caledonia and Chesterfield Islands, 5. crosnieri, which has a very unusual stylocerite, broadly rounded distally, which distinguishes it from ail other members of the family. It may be noted that several points in the systematics of the Stylodactylidae remain obscure. These will necessitate the examination of new collections. This work, however, shows the particular interest of these collection, concerning a little known and poorly represented family (nine new taxa described, representing more than one third of the species known until now), and indicates the richness of New Caledonia and Chesterfield Islands waters, where thirteen species have been collected, including six of the nine new ones. Ail the new taxa have been illustrated, and individual variations carefully studied in the species represented by numerous specimens. Color photographs of several species, taken on board during some of these cruises, complété the iconography. Identification keys are proposed for the four généra and twenty six species and subspecies now recognized in the family.

Seven shrimp species of the family Stylodactylidae are reported here from Taiwanese waters, four of which represent new records for the area. Only three species of this family were previously known from Taiwan: Stylodactylus in multidentatus Kubo, 1942, and Parastylodactylus bimaxillaris (Bate, 1888), both present in the collection studied here, and Bathystylodactylus inflatus Hanamura & Takeda, 1996, no material in the present collection. Stylodactylus major Hayashi & Miyake, 1968, is recorded for the second time. The other species are: Stylodactylus libratus Chace, 1983, Stylodactylus licinus Chace, 1983, and Stylodactylus tokarensis Zarenkov, 1968. On another hand, the status of a seventh species, related to Stylodactylus pubescens Burukovsky 1990, is left unresolved. The rare deep-sea shrimp family Bathypalaemonellidae is added to the Taiwanese decapod fauna, being represented by four species, one of which is new: Bathypalaemonella hayashii Komai, 1995; Bathypalaemonetes brevirostris (Bruce, 1986); Bathypalaemonetes pilosipes (Bruce, 1986) and Bathypalaemonetes chani, new species.

The greatest part of the types of the brachyuran crabs (Crustacea, Decapoda) in the Crustacea collection of the Museum national d'Histoire naturelle, Paris, is already catalogued on registers and is to be gradually published. This first annotated catalogue lists the nominal species belonging to the Podotremata (i.e. crabs with coxal male and female gonopores, and spermathecae): families Homolodromiidae, Dromiidae, Dynomenidae, Homoliclae, Poupiniidae, Cycloclorippidae, Cymonomidae, Phyllotymolinidae and Raninidae. The names of the taxa are presented in their original combination. The erroneous references to specimens as "types" have been noted and corrected in conformity with the International Code of Zoological Nomenclature. The types of a total of 104 species are listed herein, out of about 370 known species of podotreme crabs. Photographs of most of the type specimens are also provided. A bibliography and an index are included.

The numerous samples collected during the MUSORSTOM I and II expeditions, to which were added those of the Albatross made in 1908 and 1909 in the Philippines, those of the Vauban made from 1970 to 1974 in Madagascar, as well as various others, have permitted a revision of the genus Parapenaeus in the Indo-West Pacific. Ten species, of which two new ones, P. fissuroides and P. perezfarfantae ; two sub-species, both new, P. fissuroides indicus and P. fissuroides erythraeus, are thus recognized. Moreover, two forms are named. An identification key of species, sub-species and forms, as well as drawings of each one of them are published.

Ten species, of which three, M. liui, M. angusta and M. erythraea, are new, and one subspecies, M. provocatoria longirostris, also new, are recognized.

Samples collected around Madagascar and La Réunion, which included seven species of the genus Heierocarpus, led to the re-examination of all the Heterocarpus (nine species) reported previously from the region. A new species, H. calmani, which had been confounded until now with H. woodmasoni Alcock, 1901, is described. The occurrence of H. lepidus de Man, 1917, of which the specimens collected in the region had been identified wrongly as H. fricarinatus Alcock and Anderson, 1894, is proved. The re-examination of the type of H. unicarinaius Borradaile, 1915, only known specimen of this species, permits the completion of its description, but makes one wonder if this species really belongs to the genus Heterocarpus. Comparisons between specimens from Madagascar and La Réunion and specimens from the West-Pacific and from the Atlantic permit the consideration of variations associated with geographical areas and depths of sampling for H. dorsalis Bate, 1888, H. ensifer A. Milne Edwards, 1881, H. laevigaius Bate, 1888, H. lepidus de Man, 1917, and H. sibogae de Man, 1917. These comparisons also allow better definition of the features separating H. lepidus from H. gibbosus Bate, 1888, and H. iricarinatus. A careful examination of the (( ensifer )) complex permits the description of two new species, H. aniacula and H. huyasliii, and the elevation to specific rank of H. parvispina, considered, until now, to be a subspecies of H. ensifer. On the other hand, H. tricarinaius is split into two subspecies, H. tricarinaius iricarinaius, found in the Indian Ocean, and H. [ricarinatus angustus subsp. Nov., found in the West-Pacific. A key is offered for their dentification of the 25 recognized species and subspecies of the genus. Moreover, attention is drawn to the interest often presented by the coloration in the species of this genus.

Twenty-seven species of penaeid shrimp, belonging to the Benthesicymidae, Aristeidae and Solenoceridae families, were collected during the MUSORSTOM 1, 2 and 3 expeditions in the Philippines. None of them are new but several had not been previously reported from the Philippines and the known geographical range of some has been considerably extended. This is the case, particularly, with Parahepomadus vaubani Crosnier, 1978, known in Madagascar and Haliporus taprobanensis Alcock and Anderson, 1899, known in Madagascar and Southern India. An observation of distinct variations in Hymenopenaeus equalis (Bate, 1888) caused us to reassess specimens previously identified as this species by various authors, to correct some of these identifications and to determine more clearly the range of this species. This revision has led us to reexamine the synthypes of H. obliquirostris (Bate, 1881), only the female of which is known, and to publish drawings of specimens collected around the Hawaii islands, wrongly identified as H. equalis by Rathbun in 1906, and which must belong to an undescribed species very colsely related to H. obliquirostris. This, and the examination of the other Hymenopenaeus species in our samples, led us to attempt a better definition of the differences distinguishing H. obliquirostris, the species from Hawaii, H. neptunus (Bate, 1881), H. halli Bruce, 1966, and H. furici Crosnier, 1978. An examination of specimens belonging to Solenocera novaezelandiaa, Borradaile, 1916, supports the synonymy of this species with S. comata Stebbing, 1915, the slight differences observed being perhaps at most distinctive of forms. On the other hand we do not consider S. alticarinata Kubo, 1949, to be synonymous with S. choprai Nataraj, 1945, as several previous authors have done. Lastly, we distinghished two forms, alfonso and inermis, of Solenocera alfonso Pérez Farfante, 1981.

This paper is a continuation of the work published in 1987, in which a group of 10 species and one subspecies of Indo-West Pacific Metapenaeopsis without stridulating organs were treated. The study presented here is based on abundant material supplied by a large number of ORSTOM collections made in the Indo-West Pacific (Madagascar, Seychelles and New Caledonia) and by joint expéditions by ORSTOM and the Muséum national d'Histoire naturelle (MUSORSTOM 1-6, CORINDON, BIOCAL, BIOGEOCAL, CHALCAL 1 and 2 cruises) in the Philippines, Indonesia, New Caledonia and Chesterfield Islands and by the MD 32 cruise in the vicinity of La Réunion, supported by the TAAF (Terres Australes et Antarctiques Françaises). Additional material from the collections of the National Muséum of Natural History, Washington, from several Australian Muséums, as well as from the Muséums of Amsterdam, Leiden, Copenhagen and Frankfürt was also examined. Problems have occurred because of insufficient original descriptions and these have resulted in many errors in the Iiterature. All the type specimens have been re-examined (except for M. gallensis Pearson which is apparently lost), and also most of the specimens cited in the Iiterature. Corrected identifications and distributions are given. Among the species previously described, 18 are recognized as valid, either as species or as subspecies : M. assimilis (de Man, 1920), M. ceylonica Starobogatov, 1972, M. commensalis Borradaile, 1898, M. dalei (Rathbun, 1902), M. distincta (de Man, 1907), M. evermanni (Rathbun, 1906), M. faouzii (Ramadan, 1938), M. gallensis (Pearson, 1905), M. hilarula (de Man, 1911), M. Iamellata (de Haan, 1844), M. mannarensis de Bruin, 1965, M. mogiensis consobrina (Nobili, 1904), M. mogiensis mogiensis (Rathbun, 1902), M. quinquedenta (de Man, 1907), M. tarawensis Racek & Dali, 1965, M. vaillanti (Nobili, 1904), M. velutina (Dana, 1852), M. wellsi Racek, 1967. Six species are considered to be synonyms : M. borradailei (de Man, 1911) = M. commensalis Borradaile, 1898. M. bruini Starobogatov, 1972 = M. mogiensis consobrina (Nobili, 1904). M. caliper Liu & Zhong et al., 1988 = M. velutina (Dana, 1852). M. insona Racek & Dali, 1965 = M. velutina (Dana, 1852). M. perlarum (Nobili, 1905) = M. mogiensis consobrina (Nobili, 1904). M. raceki Starobogatov, 1972 = M. assimilis (de Man, 1920). Fifteen species and 2 subspecies are described as new : M. costata, M. difficilis, M. gaillardi, M. incisa, M. laubieri, M. marquesas, M. menoui, M. mogiensis complanata, M. mogiensis intermedia, M. parahilarula, M. persica, M. propinqua, M. proxima, M. quadrilobata, M. richeri, M. spatulata, M. spiridonovi. A total of 35 species and subspecies (not counting one form described under the name M. aff. Distincta which is probably new) are treated. Thus 46 species and subspecies of Metapenaeopsis lacking stridulating organs are now known to occur in the Indo-West Pacific. Two identification keys are presented : one for males, another for females. They are mainly intended as a guide to the numerous figures included in the paper. Illustrations of the genitalia provide assistance in recognizing the characters used to separate the species. All the petasmata are depicted with lobes both closed and separated. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies high species diversity of the Philippines-Indonesia fauna is evident. Déductions about the biogeography must be regarded with caution because they may reflect differences in sampling effort across the various areas and also because many small species have not been adequately collected. It is of particular interest to note that in the New Caledonian region, where there have been many collections made using a variety of methods, 17 species are known, whereas from the vast Philippines-Indonesia region only 19 have been recorded and only 9 from the whole of Australia. Finally some general considerations on the genus Metapenaeopsis are presented and it is suggested that the species currently assigned to it should perhaps be placed in 2 or 3 genera. An effort has been made to define the groups that might be deserving more formal recognition.

Based on rather abundant material from the Indo-West Pacific, the number of species in the genus Parathranites Miers, 1886 is elevated from two to eight. The six new species are P. granosus n. sp., P. tuberosus n. sp., P. tuberogranosus n. sp., P. ponens n. sp., P. intermedius n. sp. and P. parahexagonum n. sp. Examination of the type series of the type species for the genus, P. orientalis Miers, 1886, shows that it contains two species; a lectotype is designated for P. orientalis. The main morphological characters used for differentiating the species are the breadth/length ratio of the carapace (correlated with the length of the fifth anterolateral teeth of the carapace) which can vary from 1.3 to 2.1, the presence or absence of a median tubercle on the posterior part of the cardiac area, the granulation of the carapace and the shape of the first male pleopods. An identification key for members of this genus is proposed.

Penaeopsis (Crustacea, Decapoda, Penaeidae) collected in the south-west Pacific by French expeditions since 1976. Description of a new species. This work is based on collections made in the south-west Pacific by IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris. It deals with four species of Penaeopsis Bate, 188 1: P challengeri de Man, 1911, P eduardoi Perez Farfante, 1977, P rectacuta (Bate, 188 1), and a new species, P mclaughlinae n. sp. Depth zones and geographic distributions of the three known species are revised, especially those of P challengeri. Penaeopsis mclaughlinae n. sp. is closely related to P eduardoi but it is easily distinguished by the more sinuous shape of the distal part of the ventrolateral lobules of the petasma, and the large rounded protuberance on the median plate of the thelycum.

This work deals with 31 species of Sicyonia H. Milne Edwards, 1830, based on the collections made by the IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris, and on the collections of 28 other museums. Nineteen species are considered valid: S. australiensis Hanamura Wadley, 1998; S. benthophila de Man, 1907; S. bispinosa de Haan, 1850; S. curvirostris Balss, 1913; S. fallax de Man, 1907; S. furcata Miers, 1878; S. inflexa (Kubo, 1949); S. japonica Balss, 1914; S. laevis Bate, 1881; S. lancifer (Olivier, 1811); S. longicauda Rathbun, 1906; S. nasica Burukovsky, 1990; S. ocellata Stimpson, 1860; S. parafallax Crosnier, 1995; S. parvula de Haan, 1850; S. rectirostris de Man, 1907; S. trispinosa de Man, 1907; S. truncata (Kubo, 1949) and S. vitulans (Kubo, 1949). Four species are considered to be synonyms: S. cristata (de Haan, 1844) = S. lancifer; S. formosa (Chan & Yu, 1985) = S. furcata; S. ommanneyi Hall, 1961 = S. ocellata; S. nebulosa Kubo, 1949 = S. laevis. Twelve species are described as new: S. abathophila n. sp., S. adunca n. sp., S. altirostrum n. sp., S. dejouanneti n. sp., S. komai n. sp., S. longicornis n. sp., S. metavitulans n. sp., S. parajaponica n. sp., S. robusta n. sp., S. rocroi n. sp., S. rotunda n. sp. and S. taiwanesis n. sp. Some forms, near S. australiensis and S. dejouanneti n. sp., are mentioned but not named because the material available is insufficient. An attempt is made to classify the Indo-West Pacific species of Sicyonia into eight groups. Some groups are coherent, while others are certainly artificial. Some species cannot be placed in any of the groups and the placement of several species known from one sex only remains hazardous. An identification key is presented. Particular care was taken in illustrating the genitalia, which provide the most important characters for recognizing the species. Colour photographs show the coloration of living specimens of 17 species. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies, high species diversity of the Philippines-Indonesia fauna is evident, as well as the reduction of the number of species when one moves away from the area, except for New Caledonian area because of the unusually high h density of the samples collected in this area.

Over the last decade or so, much has been written on the classification of Decapoda, fuelled by a surge in molecular phylogenetic studies, as well as close scrutiny of internal and external morphological characteristics. As discussed by Fransen & De Grave (2009), such studies on shrimps are still somewhat ”thin on the ground”, at least compared to the more extensive work done on the Brachyura and Anomura. At a higher level in decapod classification it has long been recognised that three distinct lineages of shrimps can be distinguished: Dendrobranchiata, Stenopodidea and Caridea, a system which has not been seriously challenged by recent studies. The internal classification of Dendrobranchiata and Stenopodidea alike has been stable for some time, with the only major addition being the family Macromaxillocarididae Alvarez, Iliffe & Villalobos (2006) to the Stenopodidea in recent years. A different picture has emerged for Caridea very recently with Bracken et al. (2009) and Chan et al. (2010), both drawing attention to the non-monophyletic status of certain superfamilies and families. Further, we are aware of work currently in progress (some by the authors of this compilation) corroborating the hypothesis that the current classification of Caridea is unnatural, lines of study which will lead to the resurrection of certain family names as well as further refinement to other families. As one of our objectives for the current effort was to link this compilation of species level information with the earlier work by Chace (1992) for families and Holthuis (1993a) for genera, we have elected to largely follow the classification outlined by De Grave et al. (2009) which builds upon this earlier work. As such, it was deemed advisable to include the recently resurrected family Acanthephyridae Spence Bate, 1888 in the superfamily Oplophoroidea, rather than in this catalogue to create a new superfamily, which would perhaps be more congruent with the results in Chan et al. (2010). Although we follow herein the classification scheme of De Grave et al. (2009), two recent changes have been implemented. The clarification of the status of Galatheacaris abyssalis Vereshchaka, 1997a, as the megalopal stage of Eugonatonotus chacei Chan & Yu, 1991a, by De Grave et al. (2010) resulted in the removal of the family Galatheacarididae and superfamily Galatheacaridoidea in the current listing. Bracken et al. (2010) clarified the status of the family Procarididae, resulting in the recognition of a fourth group of shrimp, Infraorder Procarididea.

The small family Retroplumidae, one of the smallest among Barchyura, includes only two genera in the Recent fauna : Retropluma Gill, 1874, with 6 species, two of which are new ; and Bathypluma, gen. nov., with three species, two of which are also new. The first part of this work deals with systematics of the family. It is based mainly upon the material collected in the Philippines in the course of the first three MUSORSTOM expeditions. In addition to the description of the new taxa, Retropluma serenei, R. quadrata, Bathypluma spinifer and B. forficula, the previoulsy known ones are revised. This is supplemented by a few comments on the geographical and bathymetrical distribution of the various species, and by a few remarks concerning their ecology. In the second part, a critical review of fossil remains attributed to the family reveals that only Eurafricans or Asiatic fossils belong with certainty to the retroplumid lineage and that the species of American origin so far described should be excluded from the group. A detailed story of both living and extint species of retroplumids shows the great originality of this little group, which is unique in particular so far as the morphology of the orbito-antennary region and of the posterior thoracic region go. They appear in the fossil records from the origin of the upper Cretaceous, and it may be surmised that they represent an early offshoot of the main eubrachyuran, or true crab, line. The rank of superfamily herein assigned to the family Retroplumidae indicates the impossibility of linking this small group to any other family of Brachyura.

The biological exploration of deep-sea benthos off New Caledonia during the years 1978-1989 has yielded a rich mollusc fauna, including 30 species of Pectinoidea. The highest diversity, with 14 species, is observed in the 600-800 m depth interval, and only three species have been collected below 1500 m. The fauna belongs to Propeamussiidae (21 species, all taken alive), Entoliidae (1 species, alive), and Pectinidae (8 species, 6 taken alive). Nine species are new to science: Parvamussium multiliratum, P. retiaculum, P. retiolum, P. squalidulum, P. undisonum, P. vesiculatum, Cyclopecten horridus, C. pellucidulus (Propeamussiidae), and Hyalopecten mireilleae (Pectinidae). Most of the other species are new records for the region. Ten lectotypes are designated, one new synonym and one new combination recognized. This pectinoid fauna shows a strong similarity to that of the wider Indo-Pacific, and marginally to that of northern New Zealand and southeastern Australia.

Twenty-four pectinoidean species are recorded from Lord Howe Island (7 species), Norfolk Island (13 species) and the Kermadec Islands (14 species). Eighteen species are new records, and these are compared with similar species from the Australasian region. The following taxa are newly synonymised: Annachlamys leopardus rena Iredale, 1939 (= A. kuhnholtzi (Bernardi, 1860)), Chlamys cellularis Oliver, 1915 (= C. c. coruscans (Hinds, 1845), Chlamys (Mimachlamys) asperrimoides Powell, 1958 (= M. senatoria (Gmelin, 1791)). Chlamydella favus lemchei Powell, 1958 is considered to be specifically distinct from Cyclopecten favus Hedley, 1902, and is referred to Cyclochlamys Finlay, 1926. Lectotypes are for the following species designated: Hemipecten forbesianus A. Adams & Reeve, 1849, Ostrea senatoria Gmelin, 1791, and Ostrea porphyrea Gmelin, 1791.

The report is based on a collection of 344 samples of pectinoids from the Red Sea and adjacent waters. Four species of Propeamussiidae and 18 species of Pectinidae were recognized. One pectinid taxon, Mirapecten yaroni, is undescribed. Three taxa are new pectinid records for the area: Delectopecten musorstomi Poutiers, 1981, Glorichlamys quadrilirata (Lischke, 1870), and Mimachlamys andamanica (Preston, 1908). Gloripallium pallium (Linnaeus, 1758) is recorded as living in the area for the first time. Lectotypes are designated for Similipecten eous (Melvill in Melvill & Standen, 1907) Decatopecten flabelloides (Reeve, 1852), Coralichlamys madreporarum (G.B. Sowerby 2nd., 1842) and Semipallium crouchi (Smith, 1892'). Type localities of 20 taxa and the depository of type material for 19 taxa are given. All taxa are figured and extensive synonymy is presented. Intraspecific variation of most taxa is described. The total geographic distribution of each taxon is outlined. The following taxa may be endemic for the Erythrean subprovince: Propeamussiidae: Parvamussium formosum (Melvill in Meivill & Standen, 1907), P siebenrocki (Sturany, 1901), and P thyrideum (Melvill in Melvil1 & Standen, 1907); Pectinidae: Pecten erythraeensis G.B. Sowerby 2nd, 1842, Gloripallium rnaculosum (ForsskCll, 1775), Laevishlamys superficialis (Forsskal 1775). Two taxa: L. superficialis (Forsskal 1775) and Mimachlamys senatoria (Gmelin, 1791) are recorded from the Little Bitter Lake, Suez Canal. None of the taxa dealt with has migrated into the Mediterranean Sea.

The discovery of an existing member of the Glypheidae, a family believed to have been extinct since the Eocene, may yield significant information on the evolution and classification of the decapod Crustacea. The single known specimen displays characters not apparent infossil material, some ofthem perhaps representative of an ancestral decapod lineage, others reminiscent of the Astacidea and Thalassinidea.

The Pylochelidae differ from the other hermit crabs by the complete segmentation of the abdomen and the presence of paired appendages on each of its segments. They do not usually inhabit gastropod shells, but dwell in decayed pieces of wood, stones, tusk-shells, or living sponges. A recent revision, founded on most of the previously recorded specimens and on a large unidentified collection, increased the number of known species from 16 to 39, and the genera from 5 to 7. Two new subgenera have been established, and the family divided into six subfamilies. This paper deals first with the eco-ethological characteristics of the different taxa. According to their dwelling, genera and subgenera can be classified, as a whole, as xylicolous, petricolous, tusk-dwellers, spongicolous, with a few specifical or individual exceptions. In connection with the habitat, adaptive features have been described: opercular structures, boring "rasp," stridulating apparatus ... The Pylochelidae are present in the Indo- West Pacific (36 species or subspecies in 6 genera), and in the NW Atlantic (4 species in 3 genera). Two genera only, belonging to the sole non monotypic subfamily, provide a biogeographical link between the two areas. In I-W.P., the family is known from the SW Indian Ocean to Japan, Kermadec Islands and New Zealand. Indonesia, with 14 species and 5 genera appears as a center of dispersion and diversification. Japanese endemism is noteworthy: one genus and six of the seven species have not been reported elsewhere. The probable relation between the availability of dwelling material and the geographical distribution is also discussed. The vertical distribution extends from 30 to 1,570 m, but the group is mostly represented between 200 and 500 m, where 28 species are living.

The family Pylochelidae or « symetrical pagurids » (Crustacea Coenobitoidea). Pylochelid Pagurids differ mostly from all other members of the section by a well developped abdomen, in which ail segments are articulated and provided with a pair of appendages, similar in this way to many other Reptant Decapods. They are commonly called " symmetrical " Pagurids, but this is not correct, since in one genus the abdomen, telson and pleopods are noticeably asymmetrical. Our knowledge of the group was restricted to 16 species, recorded from a few rather deep water stations in Indo-West-Pacific and Western Atlantic, most of them known only from their type localities. The abundance of new material, originating mainly from Albatross dredgings and from recent French explorations in the I.W.P. has led to the present systematic revision. As a resuit, 24 new species or subspecies are added to the 16 previously established valid species ; the five known genera, Pomatocheles, Pylocheles, Mixtopagurus, Cheiroplatea, and Parapylocheles, have been redefined, some species of Cheiroplatea transfered to Pylocheles and the latter divided into three subgenera (Pylocheles, Xylocheles subgen. Nov. And Bathycheles subgen. Nov.). Besides, two genera, Cancellocheles gen. Nov. And Trizocheles gen. Nov. Are created. The Pylochelidae could be considered up to now as a restricted family of infrequent species : apart from 3 forms reported in several occasions from Japanese waters, the whole number of specimens recorded in literature did not exceed 60, captured in about 30 stations. The present revision includes more than 400 specimens, collected in ca. 200 stations ! The importance of Pylochelid fauna in tropical and subtropical waters must therefore not be neglected, and, most probably, new taxa and new localities will be added in the future. This research however has not been restricted to the description of new forms. Investigations on relationships between the various généra have shown that the whole group is made up of several distinct phyletic lines, whose respective affinities do not appear clearly, and the family had to be divided, at least provisionnaly, into 6 subfamilies. Regarding the systematic position of the Pylochelidae within the section Paguridea, they are classified in the superfamily Coenobitoidea, and a comparative study of their main characters suggests that they are close to the family Diogenidae. They cannot however be regarded as primitive représentatives of that family : both Diogenidae and Pylochelidae probably have a common ancestor, but evolved separately along various phyletic lines. In the taxonomic part of this work is also described and illustrated for the first time the glaucothoe stage of a Pylochelid, Pomatocheles stridulans sp. Nov. The richness of the new material at the origin of the systematic revision of the family has also provided a quantity of information on the ecology or the habitat of many forms, and on the interprétation of various adaptive morphological structures. According to their dwelling, généra and subgenera can be classified, as a whole, as xylicolous, petricolous, tusk-dwellers, spongicolous, with a few specific or individual exceptions. In connection with the habitat, adaptive features have been described : opercular structures, boring "rasp", stridulating apparatus... The Pylochelidae are known from two disjunct areas, the Indo West-Pacific (36 species or subspecies in 6 genera and 5 subfamilies) and the North Western Atlantic (4 species in 3 généra and 2 subfamilies). In Indo- West Pacific, their distribution is extremely wide, from South Africa to the Kermadec Islands, and from Japan (ca. 38° N) to southern New Zealand (ca. 46° S). Indonesia, with 14 species and 5 généra appears as the center of dispersion and diversification. Japanese endemism is noteworthy : one genera and 6 out of the 7 species have not been reported elsewhere. In North Western Atlantic Pylochelidae, poorly represented, extend from Bardados to the North Western part of the Gulf of Mexico and from ca. 10° N to 35° N. Two genera only, belonging to the sole non monotypic subfamily (Pylochelinae) provide a biogeographical link, probably from Tethyan origin, between the two areas. The probable relation between the availability of dwelling material and the geographical distribution is also discussed. The vertical distribution extends from 30 to 1,570 meters, but the group is mostly represented between 200 and 500 m, where 28 species have been found. 3 species only are presumably usually living above 200 m, 9 have been recorded from 500 to 750 m and no more than 5 beyond.

Laurentaeglyphea, a new genus for the second recent species of Glypheid recently discovered. (Crustacea Decapoda Glypheidae). In 1975, a recent member of a large group of Crustacea Decapoda was described as Neoglyphea inopinata Forest & de Saint Laurent, until now only known as fossils and presumed extinct since the Eocene. The only known specimen had been collected in the Philippine waters, in 1908, at a depth of 200 m. During the next years, three oceanographical expeditions gave more adult specimens, allowing complete study of the species. From its morphology, it appeared that the status attributed to glypheids in the past in the classification of Decapoda Crustacea was quite erroneous. This group, until then considered as related to Palinurids (rock lobsters) was in fact much closer to Astacids (lobster, crayfish, etc.). In 1982, N. inopinata was recorded from the other side of Equator, from the Timor Sea. In October 2005, a second living species of glypheid was discovered southwest of New Caledonia. It was named Neoglyphea neocaledonica B. Richer de Forges, 2006. However, important and significant differences set apart the two species, especially the ornamentation of the cephalothorax, the conformation of the cephalic part and the proportions of epistom and thoracic appendages, being much more robust. It seems justified to establish, for the more recently described species, a new genus, Laurentaeglyphea, much closer to fossil forms.

Until recently, the family Glypheidae (Decapoda, Reptantia) was known from fossils only, and consequently presumed extinct for 50 million years. However, in 1975 scientists of the Museum National d'Histoire Naturelle in Paris recognized a Recent specimen as belonging to this family. The specimen had been collected in the Phillippines in 1908 at approx. 200 m depth, and had remained unidentified in the collections of the Smithsonian Institution, Washington, D.C., since. That same year, the species was described as Neoglyphea inopinata Forest & de Saint Laurent, thus testifying the actual persistence of the group in today's marine fauna. Three expeditions in the same region, in 1976, 1980, and 1985, yielded another 20 specimens, all caught alive. The subsequent study of those specimens would indicate that the phylogenetic position assigned to the glypheids until then had, in fact, been erroneous. The same applied to the other mesozoic families included in the superfamily Glypheoidea. The glypheoids had usually been placed next to the Scyllaridae and Eryonidae in the infraorder Palinura, and been considered probable ancestors of part of the remaining Decapoda Reptantia. However, their similarities would come out to result rather from analogous resemblances than from actual morphological affinities. In fact, after comparison of the principal characters of the three groups, we have been able to confirm that the Glypheoidea did not exhibit any true relationship with the two others. In contrast, they proved to be closer to the Astacidae and could, eventually, be ranked with those in the same infraorder. A number of recent publications, largely by palaeontologists and based in part on cladistic as well as molecular analyses, have lately supported this point of view. They completely reject the inclusion of the glypheoids in the Palinura, corroborate their affinities with the Astacidea, and exclude the possibility that they would represent a primitive group from which other Reptantia could have evolved. The lineage of the Glypheoidea most probably appeared in the Permian-Triassic, prospered in the Jurassic, and subsequently declined from the Cretaceous to the Eocene. It is apparent that the group has not become extinct during that era, but has silently persisted, without leaving fossil traces, with at least two representatives in today's living world. Indeed, a second species of glypheid has recently been discovered in the southwestern Pacific. Though described under the name Neoglyphea neocaledonica, it shows such differences with N. inopinata that I have established a new genus for this species, Laurentaeglyphea, which is even closer to the glypheids known from the Mesozoic and the Eocene.

The anthiine genus Plectranthias Bleeker (1873)(Serranidae: Anthiunae) has been recentlyrevised by J .E. Randall (1980). Later collection in Western Pacific by author and colleagues have provided three new species, thus raising to 33 species the total number of known species in that genus. Plectranthias maculatus, from the Philippines, caught bettween 129 and 177 m depths by trawl-nets, is distinguished from the other Plectranthias species through its high gillrakers count - 30 to 31, it deep body , steep snout profile, and a large dark brown spot on its back, just below three dorsal fins. Plectranthias barroi, from the Chesterfield Islands (Coral sea) in 300 depths, is very distinctive among the other known species of Plectranthias with a peculiar filamentous ventral rays, and elongated rays in anal and caudal fins. Chelidoperca lecromi, also from the Chesterfield Islands, same depths as P. barroi, differs from other Chelidoperca by its yellow colour and belly striped. The interorbital space of that new species is covered with a scaled band, as C. hirundinacea from which it seprates by lower gill rakers counts (14 vs 18), lower number of pectoral rays (15 vs 16) and of scale rows above lateral line (3 vs 4). Its dorsal spines display a slight curvature close ti their tip, while they are all straight in C. hirundinacea

The collections of the deep water calappid crab genus Mursia at the Muséum national d'Histoire naturelle, assembled between 1971 and 1991 off Madagascar, the Philippines and New Caledonia, have been studied, in addition to material sought from other collections. Fifteen species have been identified, of which four are new : M. a/ricana, M. danigoi, M.flamma and M. musorstomia. The allied genus Platymera, formerly submerged within Mursia, is reinstated as a distinct genus. Ali taxa are described, photographed and illustrated, and a key to their identification is provided.

The polychelids are large, uncommon, primitive decapods that inhabit the depths of the world oceans down to 5000 m, between latitudes 50°N and 55°S. A study of major deep-sea collecdons led to a revision of the family. All genera and species are redescribed and extended synonymies given. Two new genera are established: Cardus, for Polycheles crucifer (Thomson, 1873) and Homeryon, for Polycheles asper Rathbun, 1906 and a new species, H. armarium. The genus Pentacheles Bate, 1878, is revived to include polychelids in which the epipod on third maxilliped is longer than the ischium: P. gibbus Alcock, 1894, P. laevis Bate, 1878, P. obscurus Bate, 1878, P. synderi (Rathbun, 1906) and P. validus A. Milne Edwards, 1880. Stereomastis Bate, 1888 is considered a synonym of Polycheles Heller, 1862. Willemoesia Grote, 1873 is retained with but four species: W. forceps A. Milne Edwards, 1880, W. inornata Faxon, 1893, W. leptodactyla (Willemoes-Suhm, 1875), and W. pacifica Sund, 1920. In all, thirty-two species are recognized, including six new species. The bathymétrie and geographic ranges are amended and discussed. A key to the genera and species of the family is provided.

A study of major collections led to a revision of the Indo-Pacific leucosioid genus Myra Leach, 1817. The systematic status and nomenclatural disposition of each species was assessed, and many were diagnosed based on examination of the type material. A new genus, Myrine, is established for M. acutidens (Ihle, 1918) and M. kesslerii (Paulson, 1875). The genus Myrodes Bell, 1855, is synonymized with Myra. Nine species are retained as valid: M. affinis Bell, 1855, M. australis Haswell, 1880, M. brevimana Alcock, 1896, M. elegans Bell, 1855, M. eudactyla (Bell, 1855), M. fugax (Fabricius, 1798), M. grandis Zarenkov, 1990, M. mammillaris Bell, 1855, and M. subgranulata Kossmann, 1877. Five new species are established: M. celeris, M. currax, M. curtimana, M. pernix and M. tumidospina. All species are described and illustrated, extended synonymies are given, and a key for their identification is provided.

A study of the genus Leucosia Weber, 1795, revealed subdivisions within the genus. A new genus, Euclosia, is established for L. crosnieri Chen, 1989, L. obtusifrons de Haan, 1841, L. rotundifrons Chopra, 1934, and L. unidentata de Haan, 1841 and five new species: E. concinna, E. exquisita, E. nitida, E. scitula, and E. tornatilia. They differ from all other species heretofore assigned to Leucosia in having anterior margin of thoracic sinus puckered, loop-shaped. The species are described or redescribed and illustrated, extended synonymies, geographical distribution and habitat are given, and a key for their identification is provided.

A study of the leucosiid genus Randallia Stimpson, 1857, led to the description of four new genera: Tanaoa, for R. distincta Rathbun, 1893, R. pustulosa Wood-Mason, in Wood-Mason & Alcock, 1891, and a new species, T. nanus; Tokoyo for R. eburnea Alcock, 1896, and a new species, T. cirrata; Toru for R. granuloides Sakai, 1961, R. trituberculata Sakai, 1961, R. pila Tan, 1996, R. mesjatzevi Zarenkov, 1990, and a new species, T. septimus\ and Urashima, for R. lamellidentata Wood-Mason, 1892, and R. pustuloides Sakai, 1961. Randallia is restricted to its type species, R. ornata (Randall, 1839), and provisionally 12 other species currently placed in this genus pending further revision. All new genera are diagnosed and species assigned to them described or redescribed and illustrated; extended synonymies are given, and a key for species identification is provided. The type species, R. ornata, is redescribed.

Nine species of frog crabs of the family Raninidae were collected during the 1976 and 1980 MUSORSTOM cruises to the Philippines and the 1980 CORINDON II cruise in Makassar Strait. A proposed new genus, Lysirude (containing 3 species) is described and separated from the closely related genus Lyreidus. Five species (Raninoides hendersoni, R. personatus, Lyreidus tridentatus, L. stenops and Lysirude channeri) are represented by numerous specimens with far fewer specimens of Cosmonotus grayi, Notopoides latus, Lyreidus brevifrons and Lysirude griffini sp. nov. present.

Le programme «Monts sous-marins» s'est déroulé au centre IRD de Nouméa depuis 1990 sous la direction de René GRANDPERRIN. Ses objectifs étaient l'étude faunistique des pentes récifales externes, des monts sous-marins et du domaine bathyal supérieur (200-1500 m) et l'évaluation de leurs potentialités halieutiques. 32 campagnes représentant un total de 446 jours de mer ont été effectuées. 18 d'entre elles ont été consacrées à l'halieutique, 13 aux études faunistiques et une à des essais de sondeur. 1496 opérations de prélèvement ont été réalisées (445 pour l'halieutique et 1051 pour la faunistique) avec les engins suivants: casier, chalut à crevettes, chalut de fond à poissons, grand chalut de fond à poissons néo-zélandais, chalut à perche, chalut pélagique à poissons, drague épibenthique, drague à roche, drague Waren et palangre de fond. En ce qui concerne l'halieutique, les ressources des pentes externes (100-600 m) ont été étudiées en Nouvelle-Calédonie et à Vanuatu, archipel pour lequel un atlas des pêches est sous presse. Les monts sous-marins agissent comme des dispositifs de concentration de poissons pour les espèces démersales. En Nouvelle-Calédonie, ils abritent une ressource en Beryx splendens qui fit l'objet d'une exploitation commerciale. Une étude scientifique, basée sur Il campagnes, a pennis de déterminer les paramètres biologiques et dynamiques de l'espèce et de modéliser sa distribution en fonction de la profondeur. Pour la première fois, une corrélation liant la croissance d'un poisson de profondeur avec le phénomène ENSO a été établie. Des travaux de génétiques des populations sont en cours sur cette espèce. Par ailleurs, le programme «Monts sous-marins» collabora étroitement avec le programme ZoNéCo d'identification et d'évaluation des ressources marines de la zone économique de Nouvelle-Calédonie. Deux synthèses portant sur les données thonières et sur les poissons profonds furent réalisées. Un halieute participa aux campagnes de bathymétrie mettant en œuvre un sondeur multifaisceaux à bord du N.O. L'Atalante. Cinq campagnes d'exploration des ressources halieutiques profondes furent effectuées à bord du N.O. Alis à l'aide de chaluts et de palangres de fond. Elles mirent en évidence l'existence de certaines ressources jusque là ignorées des pêcheurs. Les collectes de la faune bathyale ont été réalisées dans le cadre d'opérations conjointes IRD et Muséum national d'Histoire naturelle (MNHN). L'analyse des prélèvements a été possible grâce à un réseau de taxonomistes mis en place par l'IRD (Centre de Nouméa et Antenne du MNHN) et le MNHN ; il compte 181 chercheurs appartenant à 92 institutions de 24 nations différentes, ce qui représente un effort de recherche internationale exceptionnel! Les résultats obtenus dans le Pacifique sud-ouest, et notamment en Nouvelle-Calédonie, ont révolutionné la connaissance de la biodiversité des faunes profondes. 20 volumes des Résultats des campagnes MUSORSTOM qui paraissent dans la série des Mémoires du Muséum national d'Histoire naturelle sont déjà parus (environ 10 000 pages) et un autre est sous presse. Ils traitent de plus de 4500 espèces dont plus de 1300 étaient nouvelles pour la science. 126 genres nouveaux ont été créés de même que 7 familles nouvelles. Au sein de cette étude, la Nouvelle-Calédonie apparaît comme particulièrement riche en espèces et d'une très grande originalité puisque sur-les 1619 espèces actuellement publiées, 60,7 % étaient nouvelles pour la science. Des études phylogénétiques ont été réalisées sur certains groupes zoologiques en utilisant soit des techniques de biologie moléculaire (ADN), soit des méthodes de microscopie électronique. Il s'agit des Crustacés, des Echinodermes (Crinoïdes) et des Brachiopodes, parmi lesquels plusieurs formes panchroniques ont été découvertes. L'accessibilité aux faunes de profondeurs au cours du programme «Monts sous-marins» a permis de récolter des organismes qui ont fait l'objet d'analyses par le programme de pharmacologie (Substances Marines d'Intérêt Biologique: SMIB). Deux bases de données sont directement issues des travaux du programme «Monts sous-marins». Elles concernent les données halieutiques et les données faunistiques. Les premières ont été stockées à la Structure de Gestion et de Valorisation Locale (SGVL) du programme ZoNéCo. Les secondes le sont à l'IRD. Pour chacune d'elles, une procédure de création de sites INTERNET est en cours. Le problème majeur rencontré par le programme fut la disponibilité en personnel. En effet, avec une moyenne de 6 personnes, dont un chercheur et un ingénieur d'étude à plein temps, les effectifs ne dépassèrent jamais un total de 9! Le programme disposa en moyenne de 318 kFlan, dont 40 % sur fonds IRD et 60 % sur financements extérieurs. Les financements extérieurs furent de trois types: FIDES section locale du Territoire de Nouvelle-Calédonie, programme ZoNéCo et, dans une moindre mesure, MAE. Le nombre de publications réalisées par les ressortissants du programme a été de 214, dont 139 pour lesquelles le premier auteur est un membre du programme.

Females and larvae of an ascothoracid crustacean, Endaster hamatosculum gen. et sp. nov., are described. They live in large cysts in arms of the sea-star Zoroaster carinatus philippinensis Fisher, 1916. The new genus belongs to the previously monotypic Ctenosculidae and is distinguished from Ctenosculum Heath, 1910, primarily by its wider than long, ellipsoidal carapace, and features of the thorax. The peculiar nauplii have well developed but uniramous antennae and mandibles, and the sexes are separable by the end of naupliar development. The first ascothoracid larva is more generalized than the same stage of other echinoderm-infesting ascothoracids. Endaster's possible utility as a model of the evolutionary grade between Ctenosculum and Ulophysema Brattstrom, 1936, is discussed.

60 Ophiurid species, mainly bathyal, were sampled by MUSORSTOM Expedition in the area of Manila (Philippine Islands) 4 species are new for Science: Astrotoma drachi, Ophioplinthaca manillae, Ophiurothamnus musorstomae, Ophiotreta speciosa. 13 species are refound for the first time since their original diagnosis. A new combination is established, Ophiodaphne formata, because Ophiodaphne materna Koehler (1930) appears to be the juvenile form of “Amphioplus” formatus (Koehler, 1905). Two other species are synonymized: Ophiomoeris pentagona Murakami (1944) with Ophiogyptis nodosa Koehler (1905) and Ophiothrix cumulata Koehler (1922) with Ophiothrix crassispina Koehler (1905). Amphiacantha transacta Koehler (1930) is transferred into fhe genus Amphilimna Verrill.

Some very interesting deep-sea material was collected during the MUSORSTOM expéditions 1 (1976), 2 (1980) and 3 (1985) in the Philippine waters and the CORINDON 2 expédition (1980) in the Strait of Makassar. We first describe the numerous species brought back, both uncommon and new. This account is not intended to be a taxonomic revision of the Indo- Pacific species, which may belong either to the genus Trichopeltarion A. Milne Edwards, 1880, or to the genus Trachycarcinus Faxon, 1893. Both of these genera are attributed to the superfamily Corystoidea Samouelle, 1819, the revision of which is in progress. With Trachycarcinus and Trichopeltarion, the monospecific genus Pteropeltarion Dell, 1972, from New Zealand, forms a natural group alsqo with the genus Podocatactes Ortmann, 1893, endemic to Japan, and with the American genus Peltarion Jacquinot, 1847. We can only say here that they belong to the Heterotremata Guinot, 1977. One problem was encountered, because the criteria used to separate the two Indo-Pacific genera Trachycarcinus and Trichopeltarion are morphotypal ; the fact that the type-species of these genera originated from American water complicates matters. Ail the species reported here are attributed to the genus Trachycarcinus alone, without anticipating on a future study of the phylogenetic relationships and taxonomic status of the above-mentioned genera. Two species are discovered for the second time : Trachycarcinus alcocki (Doflein) and T. ovalis (Anderson). All the others are new : Trachycarcinus aff. ovalis, from the Philippines, which is only represented by a female ; T. moosai sp. nov. and T.foresti sp. nov., from the Philippines, and a close species, provisionally named Trachycarcinus aff. Delli.

This paper contains a study of the genus Psopheticus based on collections from the area around Madagascar (leg. Crosnier & Cleva, Benthedi Exp.); from Réunion (Marion-Dufresne 1982, MD32); from the Philippines (MUSORSTOM 1-3), from the Makassar Strait (Corindon 2, 1980); and from New Caledonia (Biocal and Musorstom 4, 1985). The type species, P. stridulans Wood-Mason, 1982, is redescribed, based on a topotype, from tyhe Andaman Sea. In addition, the genus contains P. insignis Alcock, 1900 and P. hughu Rathbun, 1914, both of which are redescribed, and P. vocans Guinot, 1985. Three new species are erected : P. crosnieri from Madagascar ; P. musicus from the Philippines ; and P. insolitus from the Makassar Strait. Specimens previously reported as P. stridulans by Guinot, from Réunion, have been reexamined and are considered of uncertain status but close to P. stridulans. A key is provided for identification of the species. The armature of the ambulatory legs was found to be a reliable and complex specific character, indepedant of sex and age, and is described for each species. A large series of P. insignis evidenced pronounced allometry in the growth pattern of the anterolateral edge of the carapace and a sexual dimorphism with longer chelipeds in the male.

Crustacea Decapoda Brachyura : Revision of the family Homolidae de Haan, 1839. Collections made by scientists from ORSTOM and during French expeditions, resulting from the cooperation of ORSTOM and the Muséum national d'Histoire naturelle, in the upper bathyal zone of the Indo-West-Pacific (Madagascar, Seychelles, Indonesia, the Philippines, New Caledonia, Chesterfield Islands, Wallis and Futuna Islands) have accumulated abundant crustacean material. We have added to it the collections by various Australian, German and Soviet expeditions in regions poorly explored until now. We have studied also specimens taken by deep traps near atolls in French Polynesia and in french Anfilles. We have also been able to examine almost all the Homolidae deposited in the large museums of the world, reference and unidentified collections, and thereby to prepare an account of the Hawaiian, Japanese, Indian, African, South African and American faunas. From all these collections it has been possible to revise and restructure the Homolidae world-wide. Examination of all type specimens has been necessary, as has that of all specimens mentioned in the literature; practically all references and all identifications have been verified. The Homolidae comprise now 14 genera, studied in terms of their phylogenetic affinities : eight genera already known (Homola Leach, Paromolopsis Wood-Mason, Paromola Wood-Mason, Latreillopsis Henderson, Homolochunia Doflein, Hypsophrys Wood-Mason, Homolomannia Ihle, Homologenus A. Milne Edwards) ; two former subgenera elevated to generic rank (Homolax Alcock, Moloha Bamard) ; and four new genera (Dagnaudus, Ihlopsis, Yaldwynopsis, Gordonopsis). Until now quite poor in species, the family now contains in the whole 57 species : it is increased by 17 new species ; in addition, about ten uncertain species are leaven apart. In the cases of two genera considered amphi-Atiantic, Homola and Homologenus, a new taxon is described ; Homola minima sp. Nov. Is separated from H. barbata (Fabricius), typically Mediterranean ; and Homologenus boucheti sp. Nov. Is separated from H. rostratus (A. Milne Edwards), from the American Atlantic. Three other new species are added to Homola : H. eldredgei, H. coriolisi and H. ranunculus. The genus Paromola is confined to some species close to P. cuvieri (Risso) and two new taxa are added : P. bathyalis and P. crosnieri. Six species are attributed to Moloha of which the former is the type species M. alcocki (Stebbing), another one the ancient Latreillopsis major of KUBO (validated) ; it is augmented by two new species, M. alisae and M. grandperrini, and also The genus Latreillopsis receives three new species : L. daviei, L. cornuta and L. antennata. The new genus Ihlopsis includes, besides I. multispinosa (Ihle) (formely in Latreillopsis), one new species, I. tirardi. A third species, H. gadaletae, is added to Homolochunia. Only one species is added to Hypsophrys, H. futuna, but the genus is certainly more diverse. Three new species, H. boucheti, H. levii and H. wallis are described in the genus Homologenus. The genus Homolax, poorly known, is well defined. For each genus adiagnosis, an illustration of the principal characteristics and homologies, plus a key to all species are given. Each genus has been strictly redefined with respect to its type species and to all its species. For the numerous poorly known species a description or summary of characters differentiating it from the nearest taxon is presented H has been made by a synthetic study of all important morphological criteria ; we have reviewed all the principal arrangements and structures of Homolidae to understand their homologies and reach rigorous the nomenclature of the grooves and ornamentation of the carapace which have been often confused in the past. Some phylogenetic hypotheses are briefly presented. The place of the Homolidae in Homoloidea is commented on with a key to the three members of the superfamily. Short remarks, which will be completed in another work, on fossil representatives are outlined. Lastly, geographic and bathymétrie distribution of the genera and species are discussed. Each species is represented often with drawings and always by several photographs.

The genus Granulifusus is distributed over the upper continental shelves in the Indo-West Pacific. The 27 species (21 Recent, 6 fossil) are characterized and separated from Fusinus by a granulated surface sculpture, the Recent also by a small round operculum which does not fill the aperture. Fusus (Sipho) libratus Watson 1886 and Latirus staminatus Garrard 1966 are placed in Granulifusus, their transfer based on the above mentioned conchological characteristics and on radular evidence. Granulifusus niponicus (E.A. Smith 1879), G. kiranus Shuto 1958, G. rubrolineatus (Sowerby II 1870), G. staminatus (Garrard 1966) and G. libratus (Watson 1886) were collected during the Musorstom expeditions and the material is extensively reported on. G. bacciballus sp. nov. (North New Caledonia, 444-452 m), G. benjamini sp. nov. (Coral Sea, Chesterfield, 400 m), G. balbus sp. nov. (South New Caledonia, 470 m), G. amoenus sp. nov.

(Indonesia, Tanimbar Islands, 206-210 m) were also collected by the Musorstom expeditions and are added to this fauna and described as new species. From the collection of the Australian Museum, Sydney (AMS), one additional Recent species (G. lochi sp. nov., Western Australia, 301-310 m) and one fossil species (G. nakasiensis sp. nov., Nakasi Sandstone Beds, Late Pliocene, Fiji) are described. Lots of the remaining 8 species are studied with the exception of G. captivus (E.A. Smith 1899). The remaining 5 fossil species are listed and compared. G. rufinodis (Von Martens 1901) is tentatively regarded as a distinct species and a lectotype is selected.

The Pasiphaea cristata species group is treated herewith, as the second part of the revision of genus Pasiphaea Savigny, 1816. The group is primarily characterized by presence of a complete gill formula, unarmed posterior margin of the merus of the first pereopod, and unarmed posterior margin of the ischium and basis of the second pereopod. The group comprises twenty two species, four of which are new species from MUSORSTOM material. Pasiphaea nishiei Iwasaki proves to be a junior synonym of P. merriami Schmitt, and P. vereschhaka Burukovsky is probably a junior synonym of P. amplidens Bate. Pasiphaea australis Hanamura has the same pereopodal armatures as this group, but entirely lacks arthrobranchs and is referred to Alainopasiphaea Hayashi. The genus Pasiphaea is redefined by including Phye Wood-Mason as a synonym. A key to the species of P. cristata group is presented. Each species is defined and most species are redescribed and/or refigured.

Lophiodes infrabrunneus Smith and Radcliffe, 1912 is redescribed on the basis of all known specimens. The species is redefined as: a species of Lophiodes with three dorsal spines, postcephalic spines absent; illicium relatively short, 13.3-24.2% of SL; second and third dorsal spine relatively short, 12.2-21.2% and 9.1-20.6% of SL respectively, a narrow leaf-like flap, and tendrils present on second and third dorsal spine. Lophiodes abdituspinus is a junior synonym of L. infrabrunneus based on examination of type series of both species. L. infrabrunneus is distributed from Japan, to the Timor Sea, Salomon Is. and northwestern Australia, in eastern Indian Ocean where it occurs in depths between 208-1412 m.

The species of Chaunax are reported from the eastern Indian Ocean side of Indonesia based on a recent collection made in 2004 and 2005. Two new species from the genus Chaunax are described from Indonesia and the Philippines, both belonging to the Chaunax abei-species group. Chaunax gomoni sp. nov. is distinguished by its white peritoneum and the following combination of characters: large irregular green spots on dorsal surface when freshly dead, spots turning dark brown when preserved; head length 39.5–40.8% SL; 10 rakers on second gill arch; 11–14 neuromasts in pectoral series and 29–38 in lateral-line proper. Chaunax brachysomus sp. nov. is distinguished by its uniform pink body when freshly dead, mixed broad-based and narrow-based spines on its ventral surface, large head and short tail resulting a relatively stout body; 12 or 13 neuromasts in pectoral series and 33 in lateral-line proper; and, 9 rakers on the second gill arch. Three additional species are reported for the first time from Indonesia.

Since its foundation in 1793, type specimens of 441 asteroid species and subspecies have been deposited in the M­ uséum national d’Histoire naturelle of Paris. The annotated catalogue of all these taxa is drawn up including species whose type material could not be found in the collection. Today the Paris museum houses 1011 asteroid type specimens representing 398 nominal species and subspecies, most of which were described by Lamarck (1816), Müller & Troschel (1842), Perrier (between 1869 and 1896) and Koehler (between 1895 and 1923). Though originating worldwide, species coming from the Atlantic and Indo-West Pacific Oceans, and Antarctic waters are more numerous. A biographical directory of all those involved either in the descriptions of the species or the collection of new material as well as their dedicatee is annexed to the catalogue. Revision of the Paris collection allows to propose taxonomic changes for two species of Müller & Troschel (Echinaster crassus Müller & Troschel, 1842 and Echinaster gracilis Müller & Troschel, 1842 are synonymized with Echinaster purpureus (Gray, 1840)) and five species of Perrier (Asterias borbonica Perrier, 1875 and Echinaster clouei Perrier, 1869 are synonymized with Echinaster purpureus (Gray, 1840), Oreaster clouei Perrier, 1869 and Oreaster mammosus Perrier, 1869 with Protoreaster lincki (Blainville, 1830) and Ophidiaster chinensis Perrier, 1875 with Ophidiaster granifer Lütken, 1871).

Detailed study of the Monniot collection of copepods belonging to the family Notodelphyidae has revealed an extraordinary diversity of novel taxa. With rare exceptions notodelphyids live in association with ascidians and the Monniot collection was built up over several decades of field collecting and taxonomic research on the ascidian hosts by Drs Claude & Françoise Monniot (MNHN, Paris). This paper describes a total of 178 new species of notodelphyids from ascidian hosts and 37 new genera are established: Bathynotodelphys gen.nov., Pronotodelphys gen. nov., Ooishillgia gen. nov., Nobinerilla gen. nov., Notopygus gen. nov., Chelipygus gen. nov., Sympygus gen. nov., Vaoda gen. nov., Gosbia gen. nov., Pentachaetus gen. nov., Diceratus gen. nov., Prodoroixys gen. nov., Notoixys gen. nov., Borixys gen. nov., Cystixys gen. nov., Ammonixys gen. nov., Ctenixys gen. nov., Ademoixys gen. nov., Gallincola gen. nov., Scoliosoma gen. nov., Contoura gen. nov., Unimeria gen. nov., Mecodelphys gen. nov., Tubipedia gen. nov., Procampodelphys gen. nov., Janius gen. nov., Campodelphys gen. nov., Hamaticoxa gen. nov., Adrodelphys gen. nov., Phyllodelphys gen. nov., Lissodelphys gen. nov., Nodoscarus gen. nov., Diblastus gen. nov., Chilodelphys gen. nov., Scaridelphys gen. nov., Socotradelphys gen. nov., and Aplodelphys gen. nov. Prior to this study the Notodelphyidae comprised exactly 200 valid species classified in 46 genera, a mean species richness of 4.3 species per genus. After the addition of the new taxa described here, the family now comprises 378 species in 83 genera, a mean species richness of 4.6 species per genus. Generic diagnoses are provided for all genera represented in the collection and the availability of a wider range of taxa has allowed certain generic boundaries to be better defined, resulting in transfers of species between genera and the recognition of 16 new combinations. A further 51 existing species are also reported, and brief supplementary notes or full redescriptions are provided as appropriate.

Additional specimens belonging to the rare crangonid genus Prionocrangon Wood-Mason and Alcock, 1891 collected from recent deep-sea expeditions in the West Pacific enable a revision of this poorly known genus. The four previously described species are all valid. The type species P. ommatosteres Wood-Mason and Alcock, 1891, originally known only from the Andaman Sea, is considered to be also distributed in the Philippines and Indonesia. However, the material previously assigned to "P. ommatosteres'' by de Man ( 1920) and Chace ( 1984) from Indonesia and the Philippines actually represents a new species, P. demani sp. nov., close to P. pectinata Faxon, 1896. Prionocrangon pectinata and P. curvicaulis Yaldwyn, 1960 are still only known by their types. The distribution of P. dofleini Balss, 1913 is now extended from Japan to Taiwan. Two more new species are recognized. Prionocrangon formosa sp. nov. from Taiwan is closely related to P. curvicaulis while P. paucispina sp. nov. from Taiwan and New Caledonia is unique in having very few dorsal carapace spines. The genus Prionocrangon is newly diagnosed and a key to the species is provided. Nevertheless, a damaged specimen from the Sulu Sea could not be satisfactorily assigned to any of the above seven species, suggesting that this genus may have even higher diversity.

Exceptionally preserved specimens yield critical information about the soft-part anatomy and the evolution of organisms through time. We compiled the first global dataset of exceptionally preserved muscles in malacostracans consisting of 47 occurrences, including 18 new records, predominantly preserved in Mesozoic Konservat-Lagerstätten (>70% of occurrences). Early diagenetic mineralization through phosphatization is the dominant process for exceptional preservation of muscles in malacostracans. Over 70% of taxa with muscles preserved are compressed. Rarer, three-dimensionally preserved specimens allow more detailed study of muscles. One example are specimens of the mid-Holocene ghost shrimp Sergio sp. from Panama, showing exquisitely preserved strings of muscle fibers attached to the shell interior, resembling the muscle arrangement of modern ghost shrimps. Other fossil malacostracans, including the oldest known fossil shrimp, also show musculature similar to modern taxa. We hypothesize that this muscle conservatism may be related to the confined space within the malacostracan shell in conjunction with the relatively stable body plan of several clades. We also assembled the first dataset on muscle attachment scars in malacostracans. Unlike muscles, muscle scars are more common. Approximately 24% of 357 of the articles analyzed yielded evidence of muscle scars, but such scars were only recognized for 19% of the 162 taxon occurrences that showed muscle scars. Muscle scars are common from the Late Jurassic onwards, are found primarily in Brachyura and Axiidea, and do not suffer from a Lagerstätten-effect. Rocks with well-preserved specimens should yield an additional wealth of information on the soft part anatomy of malacostracans. Similarly, muscle scars represent an almost untapped, complementary source of information on muscle evolution.

A review of the species of the caridean genus Glyphocrangon A. Milne-Edwards, 1881 from the Indo-West Pacific Oceans is presented based on rich collections formed during French expeditions to various regions, and supplemented by extensive material deposited in various institutions throughout the world. The genus is divided into two informal groups primarily based on the development of the eye and the presence or absence of arthrobranchs on the first and second pereopods. This study treats species characterized by a well-developed eye and the presence of arthrobranchs on the first and second pereopods (herein called the Glyphocrangon spinicauda species group). A total of 54 species are recognized in the G. spinicauda species group from the Indo-West Pacific region. Of these, the following 28 are new to science: G. albatrossae (Philippines), G. amblytes (Madagascar and South Africa), G. armata (New Caledonia, Vanuatu, Fiji, Wallis and Futuna islands), G. boletifera (Gulf of Aden), G. chacei (Philippines), G. confusa (Indonesia), G. cornuta (New Caledonia), G. crosnieri (Madagascar), G. conodactylus (New Caledonia), G. dimorpha (New Caledonia), G. ferox (Madagascar), G. formosana (Taiwan and East China Sea), G. indonesiensis (Philippines and Indonesia), G. kapala (eastern Australia), G. saintlaurentae (western Indian Ocean), G. major (New Caledonia), G. lineata (Indonesia and northwestern Australia), G. parva (Philippines), G. perplexa (Japan and Taiwan), G. proxima (Philippines and Indonesia), G. punctata (Philippines), G. richeri (Wallis and Futuna islands), G. robusta (Philippines), G. rubricinctuta (Wallis and Futuna islands), G. runcinata (East China Sea), G. similior (Coral Sea), G. speciosa (New Caledonia), and G. tasmanica (Tasman Sea). Glyphocrangon andamanensis Wood-Mason & Alcock, 1891 and G. mabahissae Calman, 1939, which have been considered to be synonymous with G. investigatoris Wood-Mason in Wood-Mason & Alcock, 1891 and G. dentata Barnard, 1926 respectively, are found to be distinct species. Glyphocrangon juxtaculeata Chace, 1984, the holotype of which is a juvenile, is considered to be a junior subjective synonym of G. regalis Bate, 1888. Glyphocrangon joani Allen & Butler, 1994 is treated as a junior synonym of G. fimbriata Komai & Takeuchi, 1994. Plastocrangon Alcock, 1901 is interpreted as a synonym of Glyphocrangon. The new species are fully described and illustrated, and all but three of the previously known species are redescribed and illustrated: G. gilesii and G. smithii being diagnosed on the basis of published information, G. unguiculata Wood-Mason in Wood-Mason & Alcock, 1891 on published information and provisionally identified material from the western Pacific. One obscurely diagnosed species, G. wagini Burukovsky, 1990 from the southeastern Pacific, is also redescribed in order to establish its affinities. Lectotypes are designated for G. acuminata Bate, 1888, G. pugnax de Man, 1918, G. assimilis de Man, 1918, G. sibogae de Man, 1918, and G. megalophthalma de Man, 1918. Identification key, separated by sex, is provided. This study reveals that most Glyphocrangon species have restricted geographical ranges, with only G. caecescens occurring in both the western Pacific and Indian oceans. The geographic and bathymetric distributions of the treated species are summarized.

A review of species of the genus Parapontophilus Christoffersen, 1988 (Decapoda, Caridea, Crangonidae) from the world oceans is presented. This Study is based on the large collection obtained during French expeditions in the eastern Atlantic, western Indian, and tropical western and southern Pacific oceans, and on additional material from various museums and institutions in the world. Eighteen species, including ten new species, are divided in two informal species groups, P. gracilis (Smith, 1882) group and P modumanuensis (Rathbun, 1906) group. The first group contains I I species: P. gracilis (type species of the genus), P abyssi (Smith, 1884), P. junceus (Bate, 1888), P. profundus (Bate, 1888), P occidentalis (Faxon, 1893), P talismani (Crosnier & Forest, 1973), P cornutus n. sp., P cyrton n. sp., P difficilis n. sp., P. geminus n. sp. and P. longirostris n. sp. The second group contains seven species: P. modumanuensis (Rathbun, 1906), P. demani (Chace, 1984), P caledonicus n. sp., P. juxta n. sp., P. psyllus n. sp., P. sibogae n. sp. and P. stenorhinus in. sp. Six taxa originally described as full species by their authors and occasionally treated as subspecies, viz. P. gracilis, P abyssi, P. junceus, P. profundus, P occidentalis, and P talismani, are here maintained as full species because of the existence of morphological differences and of the partial overlap of geographical or bathymetrical ranges. All species are diagnosed or rediagnosed, and illustrated. Synonymies of Pontophilus challengeri Ortmann, 1893 with Parapontophilus abyssi and of Pontophilus occidentalis var. indica de Man, 1918 with Parapontophilus junceus were con firmed. A key to aid in the identification of all Parapontophilus species is given, although it should be used with caution because of intraspecific variations exhibited by many of the species. Bathymetrical and geographical distributions of species are also summarized. All but P. sibogae n. sp. are exclusively found at more than 200 in depth, and particularly three species, P. abyssi, P occidentalis, and P talismani, occur at abyssal depths exceeding 3000 m. Parapontophilus sibogae inhabits shallow water, recorded at depth of I I m in the type locality. Two species, P gracilis and P talismani, appear restricted to the Atlantic Ocean, although widely distributed there. Three species, P abyssi, P longirostris n. sp., and P. juxta n. sp. occur in the Indian Ocean; P abyssi is also widely distributed in the Atlantic and P longirostris extends to the central Pacific. Parapontophilus occidentalis appears restricted to the eastern Pacific. Other species are distributed in the range of the western Pacific to French Polynesia.

A review of the deep-water hermit crab species of the genus Paragiopagurus Lemaitre, 1996 from the world oceans is presented. The core specimen base for this study has come primarily from the abundant collections of species of this genus obtained during French campaigns over the last four decades, and complemented with numerous specimens from many other deep-sea expeditions and deposited in various museum holdings around the world. Paragiopagurus is one of the most speciose genus among the Parapaguridae Smith, 1882, although it is considered a phylogenetically heterogeneous assemblage and does not appear to have an apomorphy of its own. Bathymetrically, the species range in depth from 36 to 2034 m, although they occur most frequently between 200 and 1000 m. The species utilize as housing, gastropod shells (or rarely scaphopod shells, siliceous sponges, or hollow pieces of wood) that may or may not be colonized by actinians or zoanthids. In this review, 24 species are recognized, of which five are new, P. laperousei n. sp., P. orthotenes n. sp., P. oxychelos n. sp., P. trilineatus n. sp., and P. umbonatus n. sp. The new species are fully described and illustrated. All previously known species of the genus are diagnosed or redescribed, and previously published illustrations of important taxonomic characters assembled and complemented, when useful, with new illustrations. The treatment of each species includes a full synonymy, materials examined (type and non-types), colouration, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Colour photographs are included for 14 of the species. Parapagurus curvispina de Saint Laurent, 1974, a species tentatively moved after its description to Sympagurus Smith, 1883 and then to Paragiopagurus, is herein transferred with certainty to Oncopagurus Lemaitre, 1996. Parapagurus spinimanus Balss, 1911, a species that had been incorrectly placed in Paragiopagurus, is herein moved to Sympagurus. Parapagurus sculptochela Zarenkov, 1990, a taxon previously considered a junior synonym of Paragiopagurus boletifer (de Saint Laurent, 1972), is herein resurrected as a valid species of Paragiopagurus. The bathymetric and geographic distributions of Paragiopagurus species are summarized and briefly discussed, including a summary table, graph, and map with generalized distribution patterns.

A worldwide taxonomic and distributional synthesis of the deep-water hermit crab genus Oncopagurus Lemaitre, 1996 is presented. This genus, originally defined for 10 species is set apart from other Parapaguridae as well as other Paguroidea, by one synapomorphy: the presence of an upwardly curved epistomial spine. This study is based on a large amount of specimens deposited in major museums and collected during deep-sea sampling across the world oceans since the late 1800s, with the bulk of material coming from French campaigns in the Indo-Pacific, central and south Pacific during the last 40 years. A total of 24 species are recognised in this investigation, nine of which are new and fully described and illustrated. All previously known species are diagnosed or re-described, including figures assembled from recent published accounts or newly illustrated, of the most important morphological features useful for identifi cations. Information for each species includes a synonymy (full or abbreviated if a synonymy has recently been published), material examined (type and non-types), variations when signifi cant, colouration when available, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Rare colour photographs are included for five species. Species of Oncopagurus range in depth from the Continental Shelf (50 m) to the Continental Rise (2308 m), although they are most commonly found in 50–500 m. Individuals of the majority of species in this genus are minute in size (< 3 mm in shield length), species differ in subtle morphological characters, and often exhibit the same broad morphological variations related to sex and size that has been documented in species of other genera of Parapaguridae. Oncopagurus mironovi Zhadan, 1997, a taxon reported from the Nazca and Sala-y-Gómez Ridges, is considered a junior synonym of the widely distributed O. indicus (Alcock, 1905). The bathymetric and geographic distributions of Oncopagurus species are summarised and briefly discussed, complemented with a summary table, graph, and map with generalised distribution patterns. The scant phylogenetic knowledge of this genus is summarised.

For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis. The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica, proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n., is justified. As result, the genus Paguropsis is found to contain five species: P. typica, P. andersoni, P. confusa sp. n., P. gigas sp. n., and P. lacinia sp. n. Herein, Paguropsina gen. n., is proposed and diagnosed for two new species, P. pistillata gen. et sp. n., and P. inermis gen. et sp. n.; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species of Paguropsis, and another with the two species Paguropsina gen. n.

The deep-sea genus Ephyrina Smith, 1885, is reported for the first time from Taiwan. The specimens obtained all belong to one species. The Taiwanese material closely resembles E. figueirai Crosnier & Forest, 1973, in having double rows of lateral spines on each side of the telson, but consistently differs from the nominotypical form from the Atlantic in having a longer and more spinose telson,while also the dorsal depression on abdominal somite VI is slightlymore pronounced. Comparison of additional specimens from the Philippines and from Madagascar shows that the West Pacific specimens are nearly identical, but the Madagascan material seems to have characters intermediate between theWest Pacific and Atlantic forms. We decided to propose a subspecific status to the West Pacific population, in order to emphasize the slight but constant differences observed in the telson in this obviously allopatric form of the species.

Ten genera and fourteen species of lysianassoid amphipods are reported from Philippine and Indonesian waters. Nine of these are new species (Aristias coriolis, A. verdensis, Eucallisoma barnardi, Figorella corindon, Onesimoides castellatus, 0. mindoro, Paracentromedon pacificus, Pseudamaryllis andresi and Trischizostoma crosnieri). Five of the genera (Eucallisoma, Figorella, Paracentromedon, Pseudamaryllis and Trischizostoma) are new records for the south-east Asian area. Only four species (Cyphocaris anonyx Boeck, 1871, Ichnopus wardi Lowry & Stoddart, 1992, Onesimoides castellatus and 0. mindoro) are recorded from both areas.

In order to clarify the systematic status of Munida japonica Stimpson, 1858, which has been mixed with several other species constituting a complex, a neotype of this species from Kagoshima, Japan, is selected and described. Examination of the type materials of M. heteracantha Ortmann, 1892, M. semoni Ortmann, 1894 (previously merged with M. heteracantha) and M. honshuensis Benedict, 1902 (previously considered synonymous with M. japonica), discloses that they are valid species. Comparison of these species with numerous specimens from the Philippines, Indonesia, Japan, and the western Indian Ocean yields 13 new relatives species to be described.

A large collection of species of the genus Munida has been examined and found to contain 56 undescribed species. The specimens examined were caught mainly off New Caledonia, Chesterfield Islands, Loyalty Islands, Matthew and Hunter Islands. Several samples from Kiribati, the Philippines and Indonesia have also been included. The specimens were collected between 6 and 2 049 m. Some species previously known in the area (Af. Gracilis, M. haswelli, M. microps, M. spinicordata and M. tubercidata) have been illustrated. These results point up the high diversity of this genus in the region and the importance of several characters in species identification (e.g., size and number of lateral spines on the carapace, ornamentation of the thoracic sternites, size of antennular and antennal spines, colour pattern).

Twenty six species of gaiatheid crustaceans belonging to the genera Agononida Baba & de Saint Laurent, 1995 and Munida Leach, 1820, were caught off the Molucca archipelago, during the KARUBAR Cruise (October-November, 1991). Three species are described as new: A. emphereia. M. compacta and M. punctata.

The species of the genus Raymunida from the Pacific and Indian oceans are revised using morphological characters and the mitochondrial cytochrome oxidase subunit I sequences. Four new species are described (R. confundens. R. dextralis, R. erythrina, and R. insulata), and the status of R. bellior and R. elegantissima are revised. The species of Raymunida can be identified by subtle morphological characters, which match differences in mitochondrial nucleotide sequences. Therefore. the sequence divergences confirm the specific and phylogenetic value of some morphological characters (e.g., length of the mesial spine on the basal antennal segment, length of the walking legs). Furthermore. they confirm the importance of the color pattern as a diagnostic character. The widespread species (R. elegantissima), known from the Philippines to Fiji, shows minimal divergence between specimens from different localities (maximum of 3 nucleotide differences or 0.2% mean divergence). The phylogenetic reconstruction agreed with the monophyletic condition of Raymunida and its differentiation with respect to the genus Munida (in which Raymunida species had previously been included) and Agononida.

Sixty-six species of the genus Munidopsis have been studied using specimens collected during numerous French expeditions carried out in the last decades in the deep-waters of the southwest Indian and southwest Pacific Oceans, between 140 and 4400 m. Twenty-five new species are described, and the diagnoses and illustrations of some relatively rare species (M. africana, M. debilis, M. lenzii, M. moresbyi, M. orcina, M. sinclairi, M. stylirostris and M. wardeni) are provided. The reestablishment of the genus Galacantha is proposed, including the descriptions/diagnoses and a key to all species. The genus contains nine species, including three new species (G. bellis, G. diomedeae, G. quiquei n. sp., G. rostrata, G. spinosa, G. subrostrata n. sp., G. subspinosa n. sp., G. trachynotus and G. valdiviae). The number of species collected by station is very small (usually one species), probably related to their low densities. However, in some samples, as many as five species have been found. The highest number of species have been observed in the Banda Sea (Indonesia) and Solomon Islands. The new records of some species greatly extend the previously known distribution range of the species.

We analyzed the distribution patterns of the galatheid squat lobsters (Crustacea, Decapoda, Galatheidae) of the Pacific Ocean. We used the presence/absence data of 402 species along the continental slope and continental rise (200-2000 m) obtained from 54 cruises carried out in areas around the Philippines, Indonesia, Solomon, Vanuatu, New Caledonia, Fiji, Tonga, Wallis and Futuna and French Polynesia. The total number of stations was ca. 3200. We also used published data from other expeditions carried out in the Pacific waters, and from an exhaustive search of ca. 600 papers on the taxonomy and biogeography of Pacific species. We studied the existence of biogeographic provinces using multivariate analyses, and present data on latitudinal and longitudinal patterns of species richness, rate of endemism and the relationship between body sizes with the size of the geographic ranges. Latitudinal species richness along the Western and Eastern Pacific exhibited an increase from higher latitudes towards the Equator. Longitudinal species richness decreased considerably from the Western to the Central Pacific. Size frequency distribution for body size was strongly shifted toward small sizes and endemic species were significantly smaller than non-endemics. This study concludes that a clear separation exists between the moderately poor galatheid fauna of the Eastern Pacific and the rich Western and Central Pacific faunas. Our results also show that the highest numbers of squat lobsters are found in the Coral Sea (Solomon-Vanuatu-New Caledonia islands) and Indo-Malay-Philippines archipelago (IMPA). The distribution of endemism along the Pacific Ocean indicates that there are several major centres of diversity, e.g. Coral Sea, IMPA, New Zealand and French Polynesia. The high proportion of endemism in these areas suggests that they have evolved independently. (C) 2009 Elsevier Ltd. All rights reserved.

The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other collections from various sources, and including the type specimens of some previously described species. Most of the new species are distinguished by subtle but constant morphological differences, which are in agreement with molecular divergences of the mitochondrial markers COI and/or 16S rRNA. Here, we describe and illustrate the new species and redescribe some previously described species for which earlier accounts are not sufficiently detailed for modern standards. Furthermore we include a dichotomous identification key to all species in the genus from the Indian and Pacific Oceans.

Living species of Meiocardia, Glossidae, are reviewed on the basis of specimens stored in various museums and institutions, including the MUSORSTOM collection of Museum national d'Histoire naturelle, Paris. Six species, one of them new, are reported from the Indo-West Pacific. The type species, M. moltkiana (Gmelin, 1791), has been variously interpreted by authors, so we redescribe it and give a new diagnosis of the genus. Other species of Meiocardia are: M. sanguineomaculata (Dunker, 1882) (Philippines to Seychelles); M. vulgaris (Reeve, 1845) (China to Philippines); M. globosa sp. nov. (eastern Indian Ocean to Taiwan and Philippines); M. samarangiae Bernard, Cai & Morton, 1993 (Japan); and M. hawaiana Dall, Bartsch & Rehder, 1938 (western Indian Ocean to Hawaii). Meiocardia lamarckii (Reeve, 1845) is synonymised with M. moltkiana. Meiocardia lamarckii of Japanese authors is not the same as M. lamarckii (Reeve), but is conspecific with M. hawaiana. Meiocardia samarangiae Bernard, Cai & Morton, 1993 is a replacement name for Isocardia tetragona Adams & Reeve, 1850 non Koch & Dunker, 1837. The genus Glossocardia, Trapezidae, is redescribed on the basis of the type-species, Glossocardia obesa (Reeve, 1843) (tropical West Pacific). It includes Glossocardia stoliczkana Prashad, 1932 (Philippines and New Caledonia) and the tropical western Atlantic G. agassizii (Dall, 1886), which was originally assigned to Meiocardia. There are no records of living or fossil species of Meiocardia from the western Atlantic or eastern Pacific.

The hermit crab genus Nematopagurus, erected by A. Milne-Edwards & Bouvier (1892) for a single Atlantic species, has vastly larger reported representation in the Indo-Pacific region. However, the majority of species have been described on the basis of one or only a few specimens. The Musorstom expeditions to the south central Pacific and Philippine Islands, supplemented by the surveys of the United States Fish Commission steamer Albatross in Hawaiian, Philippine and Japanese waters, have provided not only a substantial amount of new material, but sufficient representation of most described species to permit the evaluation of intraspecific morphological variation. As a result, although five new species have been recognized, three recently described species have proven to be junior synonyms of previously known, but poorly represented, species. Nematopagurus holthuisi McLaughlin & Hogarth and N. pilosus Komai are synonymous with N. gardineri Alcock, while N. shinnyoae Komai is synonymous with N. kosiensis McLaughlin. The range of N. diadema Lewinsohn, reported previously from the Red Sea, the eastern coast of South Africa, and the South China Sea, has been extended to Fiji, while that of N. meiringae McLaughlin, known from eastern South Africa and the South and East China Seas, has been extended to the Philippine Islands. Nematopagurus kosiensis McLaughlin, previously known only from eastern South Africa has been found not only in Japanese waters, but also as far east as the Hawaiian Islands. Species identified by several authors as N. squamichelis Alcock and N. muricatus (Henderson) have been reexamined and correctly reassigned to other taxa. Descriptions and illustrations are presented for all species, together with a key for their recognition.

A new classification is presented based on the results of the recently completed cladistic analysis of the Pylochelidae. The subfamilies Pylochelinae and Pomatochelinae are retained, the latter with the genera Pylocheles and Cheiroplatea; however, the subgenera Xylocheles and Bathycheles are elevated to generic rank together with the nominal subgenus Pylocheles. In addition, one new species, B. phenax, is described in Bathycheles and B. profundus is shown to be conspecific with B. integer. The subfamilies Parapylochelinae, Cancellochelinae, Trizochelinae, and Mixtopagurinae are reduced to ranks of tribes and included in the subfamily Trizochelinae. A new genus Forestocheles is proposed in the tribe Trizochelini. Within the genus Trizocheles, subspecific rank for T. spinosus bathamae is deemed unjustified and this taxon is placed in synonymy with the nominal subspecies T spinosus spinosus. The correct identity of Trizocheles balssi is established and the species mistakenly thought to represent that taxon is described as T. hoensonae, new species. Trizocheles gracilis is found to be conspecific with T. boasi and an additional new species, T. mendanai, is added to the genus. The superfamilial ranks of Cheiroplateoidea, Pomatocheloidea, Pylocheloidea, and Cancellocheloidea proposed by Watabe (2007) are rejected, as is Birgusoidea.

Although this paper concerns a large collection of dromiid crabs from the Philippine Islands and New Caledonia, with a few specimens from Indonesia and Hawaii, the opportunity is taken to review and revise most of the genera of the Dromiidae. The basis of the revision involves a much wider range of characters than have been used before. Excessive emphasis on the nature of the female sternal grooves is abandoned, and more attention is paid to relative dimensions and ornamentation of the carapace, arrangement of spines on and around the dactyli of all the legs, fusion of the last two segments of the abdomen, and size of the uropod plates. A new set of characters describing the second antenna and the male abdominal locking mechanism are also used. The impxDrtance of the cheliped epipod character is discussed and is shown to be variable in some genera. A total of 28 genera are defined or redefined and a key to their identification is provided, along with keys to the identification of 99 species in these genera. The following genera are restricted and/or redefined : Cryptodromia Stimpson, 1858, Cryptodromiopsis Borradaile, 1903, Dromia Weber, 1795, Dromidia Stimpson, 1858, Dromidiopsis Borradaile, 1900, Epigodromia (a replacement name for Epidromia Kossmann, 1818, which is preoccupied), Homalodromia Miers, 1884, Paradromia Balss, 1921, Petalomera Stimpson, 1858, and Pseudodromia Stimpson, 1858, resulting in the creation of 10 new genera. Ascidiophilus Richters, 1880, Conchoecetes Stimpson, 1858, Epipedodromia Andre, 1932, Eudromidia Barnard, 1947, Exodromidia Stebbing, 1905, Hemisphaerodromia Barnard, 1954, Hypoconcha Guerin-M6neville, 1854, Speodromia Barnard, 1947, and Sphaerodromia Alcock, 1899, remain unmodified. After the elimination of many synonyms and together with the new material described herein, the Dromiidae now includes 29 genera and 109 species. The generic revision has major implications for the dromiid crabs of, not only the Philippines and New Caledonia but also, the rest of the Indo-Pacific region, Australia, South Africa, and the Atlantic. Until now only six species of dromiid crabs were known from New Caledonia and the Philippine Islands. This number is increased to 29 species belonging to 13 genera. The most common species are Lauridromia intermedia (Laurie, 1906) nov. comb., Petalomera pulchra Miers, 1884, Cryptodromia coronata Stimpson, 1858, Dromidiopsis dubia Lewinsohn, 1984, and Epigodromia areolata (Ihle, 1913) nov. comb. Most of these dromiids come from shallow water, less than 100 m, and the maximum number of sp)ecies occurs in the depth interval of 30-60 m. The greatest depth of 437 m is shown by Frodromia atypica (Sakai, 1936) nov. comb. There is a large range of body size from a few millimetres, for Homalodromia coppingeri, to around 200 mm CW, for Dromia dormia. Egg size ranges from 0.4 mm to 1.1 mm diameter but there is no evidence of direct development amongst these dromiids. The apparent biogeographic affinities of the dromiids from New Caledonia and the Philippines are, in decreasing order, with Japan, Indian Ocean, Indonesia, and Australia. The apparent affinity with Japan may well be an artifact of more intensive collecting. The most wide ranging species are Lauridromia intermedia (Laurie, 1906), Dromia dormia (Linnaeus, 1763), D. wilsoni (Fulton & Grant, 1902) nov. comb., Cryptodromiopsis unidentata (Riippell, 1830) nov. comb., Cryptodromia hilgendorfi De Man, 1888, and C. fallax (Lamarck, 1818) nov. comb. These species also represent the most wide ranging genera. The collection of species largely consists of widely distributed species typical of an island fauna.

The Dynomenidae are a group of small, uncommon, primitive crabs, which are often associated with corals. They inhabit depths down to around 500 m, between latitudes 40°N and 40°S. All genera and species are revised and redescribed, and the genus Dynomene Desmarest, 1823 is divided into two additional genera. As a result, there are thirteen known species belonging to five genera: Dynomene Desmarest, 1823 [D. hispida Guérin-Méneville, 1832, D. praedator A. Milne Edwards, 1879, D. pugnatrix de Man, 1889, D. filholi Bouvier, 1894, and D. pilumnoides Alcock, 1900], Hirsutodynomene gen. nov. [H. spinosa (Rathbun, 1911), and H. ursula (Stimpson, li>60)], Metadynomene gen. nov. [Ai. devaneyi (Takeda, 1977), M. tanensis (Yokoya, 1933), and M. crosnieri sp. nov.], Acanlliodromia A. Milne Edwards, 1880 [A. erinacea A. Milne Edwards, 1880, and A. margarita (Alcock, 1899)], and Paradynomene Sakai, 1963 [P. tuberculata Sakai, 1963]. A key is provided to identify these species. In addition nine fossil genera, dating from the Upper Jurassic, are known: Stephanonietopon Bosquet, 1854, Dromiopsis Reuss, 1859, Palaeodromites A. Milne Edwards, 1865, Cyamocarcinus Bittner, 1883, Graptocarcinus Roemer, 1887, Cyclothyreus Remes, 1895, Gemmellarocarcinus Checchia-Rispoli, 1905, Glyptodynomene Van Straelen, 1944, Trachynotocarcinus Wright & Collins, 1972. Some extinct species have also been placed in the genus Dynomene. The definition of the family Dynomenidae given by ALCOCK (1901) is updated and expanded in order to allow fossil species to be more accurately determined. Because of overlap with the Dromiidae, there has been some uncertainty about true family affinities of some fossils. Although these genera are in need of revision, this is not undertaken in this paper. The status oi Dynomene pilumnoides is established as a valid species, D. pugnatrix brevimana Rathbun. 1911 is synonymized with D. pugnatrix de Man, 1889, D. granulobata Dai, Yang & Lan, 1981 is a synonym of D. hispida, while D. sinensis Chen, 1979, D. tenuilobata Dai, Yang & Lan, 1981, and D. huangluensis Dai, Cai & Yang, 1996 are all synonyms of D. praedator. Dynomenids are reported from Australia for the first time in D. pilumnoides, and Hirsutodynomene spinosa. The status of Metadynomene tanensis (Yokoya, 1933) is established as a widespread Pacific species and shown to be part of the fauna of Japan, where it has been confused with D. praedator. Paradynomene tuberculata, previously known from Japan and New Caledonia, is now recorded from the Gulf of Aden, Indian Ocean. P. tuberculata as well as D. praedator and H. spinosa, are reported from Guam. The Atlantic Ocean and the Indo-Pacific share genera of dynomenids but not species. The biogeographic history of dynomenids is interpreted in the liglit of tfieir present distribution and in relation to plate tectonics. Ancestral dynomenids are assumed to have been tethyan crabs and D. filholi and Acanthodromia erinacea, two insular Atlantic species, are shown to be tethyan relicts. By contrast, Hirsutodynomene ursula from the eastem Pacific, seems to be a species of quite recent origin. In redescribing the species particular attention is paid to some new characters: setae, gills, epipods and gill cleaning mechanisms, the subchelate structure of the last pereopods and the male pleopods. This work was undertaken using a scanning electron microscope. Differences in the gross appearance of setae can be used to separate species and there are substantial differences in setal structure at the microscopic level. The standard branchial formula for dynomenids is shown to be nineteen gills plus seven epipods. There is little variation in gill numbers but substantial variation in gill shape between species. Although dynomenid gills are often said to be "transitional" they are arranged as in phyllobranchs but with the epibranchial part divided into varying numbers of lobes which gives them a trichobranch-like appearance. Acanthodromia has gills which are almost identical to the phyllobranchs of the Dromiidae but which retain the "dynomenid notch" on each side which, in cross section, give each gill plate a violin shape. The gill cleaning mechanism in dynomenids is complex, being carried out by no less than eight appendages (long setae on the posterior margin of the scaphognatbite and the seven epipods) as well as stiff setae on the posterior hypobranchial wall of the gill chamber. In eubrachyurans only three appendages (maxillipodal epipods) are used. In dynomenids the last pereopod is very reduced (on average less than one-third the length of the fourth pereopod) and carried in a horizontal position alongside the posterolateral carapace margin above the base of the preceding pereopod. They are not, as it has been commonly described, carried subdorsally. Using a scanning electron microscope it was revealed that this limb is sexually dimorphic: in males the dactyl has the normal shape of a tiny claw, but in females the dactyl is a flattened plate, bearing five to sixteen spines which are opposable to an extension of the propodus. In both males and females the propodal extension is armed with spines but in Hirsutodynomene. Metadynomene and Paradynotnene, females have a significantly larger number of spines, which are armed with tiny teeth. Males of three species have an additional small spine on the outer margin of the dactyl. This is a character, previously only known amongst the Dromiidae, which suggests that the last pereopod of dynomenids may have evolved from a camouflagecarrying limb. This limb appears to be vestigial and it is difficult to know what its function may have been amongst the dynomenid ancestors. However its most likely former role appears to be as a cleaning appendage, but certainly not for carrying pieces of camouflage as it is found amongst the dromiids and homolids. All dynomenids, except Acanthodromia, lack an effective abdominal locking mechanism and both sexes have five pairs of pleopods. The female has vestigial, uniramous first pleopods followed by four pairs of normal biramous pleopods, while the male has the normal first two pairs of pleopods as well as three pairs of rudimentary pleopods on segments three to five. These rudimentary pleopods can be uniramous or bifid. In Metadynomene tatiensis 17% of females were gynandromorphs with small male first pleopods but the remaining pleopods were normal. The diet of dynomenids seems to consist of food obtained by sieving fine sediment or perhaps coral mucus. The bunches of sfiff setae on the inner margins of the cheliped fingers and third maxillipeds are probably used to separate fine organic fragments. Most of their gut contents are unidentifiable soft organic material along with small amounts of chopped chitinous fragments perhaps coming from hydroids or other crustaceans. Dynomenids appear to be deposit feeders. Dynomenids have a broadcast reproductive strategy, with indirect development, laying small eggs (mean diameter = 0.49 mm) which probably produce planktonic larvae. Dynomenid larvae have never been reported in plankton samples. Males are on average 19% larger than females which become sexually mature at 5-8 mm CW for small species, or 9-13 mm CW for large species. Egg numbers increase logarithmically with body size. Given the sister group relationship with homolodromiids (which have very abbreviated development) it is implied that dynomenids and dromiids evolved from ancestors which had large eggs and perhaps a brooding strategy. This conclusion is contrary to accepted wisdom, but it is the most parsimonious answer. Some dromiids have retained the brooding strategy but others have independently evolved a broadcast strategy. The evolution of such a strategy in both these families is probably related to their colonization of the shallow water habitat. Both dynomenids and dromiids are mostly crabs of the continental shelf whereas homolodromiids are crabs of the continental slope. Using morphological characters the phylogenetic relafionships of the Dynomenidae are examined. Both the Dynomenidae and the Dromiidae are monophylefic, sharing significant apomorphies. The resemblance of some dynomenids and dromiids is shown to be the result of convergent evolution within these families. The Homolodromiidae are also monophyletic but are defined almost exclusively by plesiomorphies. Monophyly of the Dromiacea de Haan, 1833 is supported by morphological characters with the Dynomenidae and Dromiidae together being the sister group of the Homolodromiidae. The ancestor of these three families was probably a camouflage carrying crab, using both of the last two pairs of pereopods. A controversial aspect of the sister group relationships of the dromiaceans is the need to assume that in dynomenids the fourth pereopod has reverted to a locomotory role and the fifth pereopod became a cleaning limb. Monophyly of the Podotremata Guinot, 1977 is also supported. This analysis suggests that camouflage-carrying behaviour has evolved independently in the Dromiidae (and probably in the Homolodromiidae) and the Homolidae. Dromiids carry pieces of sponges or ascidians as well as shells, using the last two pairs of pereopods, while homolids carry sponges or anemones, using only the last pair of pereopods. The ancestor of the Dromiacea and Archaeobrachyura was probably an inhabitant of deeper waters and not a camouflage carrying crab.

Trente espèces de Portunidés, appartenant à neuf genres différents, ont été recueillies aux Philippines, en 1976, au cours dela campagne MUSORSTOM. La récolte de Carupella natalensis Lenz, 1914, connue jusqu'ici des eaux de la côte est-africaine seulement est d'un intérêt particulier. Lupocyclus philippinensis Semper, 1880, dont une série de spécimens ont été récoltés par l'expédition, est figuré pour la première fois à partir de matériel en provenance des Philippines. Charybdis (Goniohellus) hongkongensis Shen, 1934, qui n'avait jamais été signalé aux Philippines, a été récolté dans lem^me site que son voisin Charybdis (Goniohellenus) truncata (Fabricius, 1798). Libystes nilidus A. Milne Edwards, 1867, Lissocarcinus arkali kemp, 1923, Charybdis (Charybdis) natalor (Herbst, 1794), Lupocyclus tugelae Barnard, 950, Thalamita picta Stimpson, 1858, et Podophthalmus nacreus Alcock, 1899, sont signalés pour la première fois de cette région.

Acrothoracican barnacles of the genus Trypetesa are obligate symbionts of hermit crabs that burrow into the gastropod shells occupied by their hosts. In the present study, hermit crabs were examined for the presence of trypetesids, based on collections from the United States, Jamaica, and the Philippines made between 1997 and 2008. Shells from Jamaica and New York contained Trypetesa lateralis, a trypetesid previously documented from central California. Trypetesa lateralis is redescribed based on light and scanning electron microscopy, showing the presence of an external mantle flap and asymmetrical opercular bars diagnostic for this species. The mean prevalence of trypetesids in Jamaica was 8.3% and most barnacles were associated with Calcinus tibicen; in New York the barnacles were found in 1.6% of shells occupied by Pagurus longicarpus. Specimens from the Philippines were identified as Trypetesa spinulosa (formerly known only from Madagascar) based on the presence of their diagnostic orificial palps. The mean prevalence of T. spinulosa in the Philippines was 3.7% and most barnacles were associated with Calcinus spp. Hermit crab eggs were observed in the guts of T. lateralis from Jamaica and T. spinulosa from the Philippines. In both of these regions the trypetesids were found significantly more often in shells occupied by female hermit crab hosts (80–87% with females). These findings suggest the barnacles be classified as transient parasites. The biology of trypetesids is reviewed and a key to the family is provided. Further studies are needed to determine if egg predation occurs in all trypetesids and the impacts on hosts.

The present study limits the distribution of a deep-sea crab, Trichopeltarion ovale Anderson, 1896, to the Indian Ocean, and describes a new species of what has been referred to as T. ovale from the western Pacific and southeast Asia. Trichopeltarion danieleae sp. nov. differs morphologically from allied congeners by a combination of characters of the carapace and ambulatory legs. The new species is also distinguished from two fossil Trichopeltarion species, T. huziokai (Imaizumi, 1951) and T. inflatus (Kato, 1996).

The identities of the deep-water brachyuran crabs Carcinoplax abyssicola (Miers, 1885), C. longipes (Wood-Mason, 1891), and C. specularis Rathbun, 1914 (family Goneplacidae MacLeay, 1838) are clarified on the basis of the examination of types and of an extensive series of specimens from the Indo-West Pacific region, including colour photographs of fresh specimens. Two species described from the Philippines, C. verdensis Rathbun, 1914 and C. polita Guinot, 1989, and previously synonymised under C. specularis, are shown to be distinct species. Two new species, C. adelphia n. sp. and C. jugum n. sp., are described from Vanuatu and the Philippines, respectively. Carcinoplax adelphia n. sp. differs from the closely allied C. specularis by having a male first gonopod (G1) that is relatively more elongated, particularly the distinctly more slender distal half, than the G1 of C. specularis. Carcinoplax jugum n. sp. is characterized by a suite of characters that includes an epistome with strongly concave lateral margins, a carapace having distinctly swollen gastric and cardiac regions, and a G1 with a subconical distal part. The taxonomies of these seven species, as well as that of the allied C. fasciata Ng & Kumar, 2016 from southwestern India, are revised. A revised, updated key to the 25 known species of Carcinoplax H. Milne Edwards, 1852 is also provided.

The taxonomy of spider crabs of the genus Maja Lamarck, 1801, is revised, and a total of 36 species in 10 genera are now recognised from the eastern Atlantic, Mediterranean and Indo-West Pacific. The present revision describes seven genera and 17 species as new. Two genera previously synonymised under Maja: Paramaya De Haan, 1837, and Paramaja Kubo, 1936, are here treated as valid taxa. The confused nomenclature of Cancer cornutus Linnaeus, 1758, is resolved, and the name replaces Maja capensis Ortmann, 1894, and Mamaia queketti Stebbing, 1908. All genera and species are diagnosed and figured, and keys are provided for their identification.

The family Chasmocarcinidae Serène, 1964, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of three subfamilies comprising 16 genera (including eight described as new) and 51 species (including 19 described as new). The subfamily Chasmocarciinae Serène, 1964, consists of Amboplax n. gen. with one species; Angustopelta n. gen. with four species, two of which are new; Camatopsis Alcock & Anderson, 1899, with six species, five of which are new; Chasmocarcinops Alcock, 1900, with one species; Chasmocarcinus Rathbun, 1898, with 11 species, one of which is new; Chinommatia n. gen. with five species, two of which are new; Deltopelta n. gen. with one species; Hephthopelta Alcock, 1899, with two species, one of which is new; Microtopsis Komai, Ng & Yamada, 2012, with two species, one of which is new; Notopelta n. gen. with one species; Statommatia n. gen. with five species, two of which are new; and Tenagopelta n. gen. with three species, two of which are new. The subfamily Megaesthesiinae Števčić, 2005, consists of Alainthesius n. gen. with two species, both of which are new; Megaesthesius Rathbun, 1909, with four species, one of which is new. The subfamily Trogloplacinae Guinot, 1986, consists of Australocarcinus Davie, 1988, with three species, and Trogloplax Guinot, 1986, with one species. A neotype is selected for Chasmocarcinus cylindricus Rathbun, 1901. Three nominal species were found to be junior subjective synonyms of other species: Chasmocarcinus panamensis Serène, 1964, of C. longipes Garth, 1940; Chasmocarcinus rathbuni Bouvier, 1917, of C. typicus Rathbun, 1898; and Hephthopelta superba Boone, 1927, of Deltopelta obliqua (Rathbun, 1898). Thirteen chasmocarcinid genera are exclusively found in the Indo-West Pacific region, one (Chasmocarcinus) in both the Western Atlantic and Tropical Eastern Pacific regions, and two (Deltopelta n. gen. and Amboplax n. gen.) exclusively in the Western Atlantic. Chasmocarcinids are remarkable for occurring from depths exceeding 1000 m to shallow water and completely freshwater habitats: chasmocarcinines and megaesthesiines are found from shallow to deep water marine ecosystems, whereas trogloplacines live in freshwater streams, including cave systems.

Nine species of Upogebia Leach from the Seychelles Islands, the Philippines, Indonesia and the Gulf of Aden are studied. U. balmaorum, U. laemanu and U. gracilis are all new species and the first two are closely related to each other. The four additional species include U. baweana Tirmizi and Kazmi, U.fallax de Man, U. hexaceras (Ortmann) and U. miyakei Sakai, two of which are known only from their holotypes. They are compared here with U. pugnax de Man, U. octoceras Nobili; all are briefly re-described.

A group of venomous turriform gastropods in the subfamily Turrinae, genus Lophiotoma, has been investigated. Previously, forms in this group were identified as either Lophiotoma unedo or Lophiotoma indica. Our analysis has led to the description of four new species from the Philippines (L. bisaya, L. friedrichbonhoefferi, L. panglaoensis, and L. tayabasensis) and one each from Australia (L. capricornica), South Africa/Mozambique (L. dickkilburni), and Madagascar (L. madagascarensis). A new subspecies, L. indica queenslandica, is also described. In addition, 11 distinctive forms related to these taxa that may or may not deserve separate taxonomic status are defined; these need further evaluation. It is hypothesized that the forms of Lophiotoma discussed in this report are closely related to a particular subset of Gemmula, the G. kieneri/G. interpolata group.

Ophiuroids of the families Ophiacanthidae (46 species) and Hemieuryalidae (2 species) are monographed for the region around New Caledonia in the southwest Pacific Ocean. Ophiohamus nanus n. gen. n. sp. is described in the Ophioplinthacinae. New species are also described in the following genera: Ophiacantha (O. fuscina n. sp., O. richeri n. sp.), Ophioplinthaca (O. amezianeae n. sp.), Ophiomitrella (O. mensa n. sp., O. parviglobosa n. sp.), Ophiothamnus (O. biocal n. sp.) and Ophiurothamnus (O. eleaumei n. sp.). The genus Ophiocyclus is synonymised with Ophiurothamnus, Ophiomelina with Ophiacantha, Toporkovia with Ophiolimna, Ophiomytis with Ophioplinthaca, and Ophiogyptis with Ophiomoeris. Ophiomelina moniliformis (Koehler, 1904) thus becomes a junior homonym of Ophiacantha moniliformis Lütken & Mortensen, 1899 and the replacement name Ophiacantha renekoehleri n. nom. is proposed. In addition there are 37 new species-level synonymies and 19 other new genus-species combinations. A key is provided for all genera and all tropical Indo-West Pacific species of the Ophiacanthidae. The results show that the biogeographical relationship of the ophiacanthid fauna of New Caledonia is with the tropical Indo-Pacific. Less than ten percent of the fauna is shared with Southern Australia and fifteen percent with New Zealand. More broadly, there appears to be a single ophiacanthid fauna at upper to middle slope depths (200-2500 m) across the Indo-West Pacific from Africa to Hawaii, with limited east-west differentiation. This fauna grades into distinct temperate bathyal faunas near South Africa, China/Japan and Australia/New Zealand, until there is an almost complete changeover of species by 45° latitude in both hemispheres.

Ophiodaphne scripta (Koehler, 1904) is an amphiurid brittle star exhibiting an unusual form of conspicuous sexual dimorphism and epibiosis. The males are much smaller and exist as epibionts on the larger female. These male–female pairs, attached mouth to-mouth, are in turn epibionts on cake urchins such as Echinodiscus auritus Leske, 1778, attaching themselves via the aboral side of the female. In this paper, Ophiodaphne scripta (Koehler, 1904) is reported from off the southern Indian peninsula for the first time, extending the range of this species eastwards. The distribution of this species is discussed in conjunction with that of the only other species in this genus, Ophiodaphne formata (Koehler, 1905), which also exhibits similar sexual dimorphism and epibiotic behavior. A detailed description of the specimens from India is provided, along with adaptations to their peculiar lifestyle. In addition, a brief historical review of the systematics of the genus Ophiodaphne Koehler, 1930 is presented, pointing out some discrepancies which persist, despite numerous revisions.

The University of the Philippines (UP) Biology Invertebrate Museum has recently completed the curation of its accessioned collections of invertebrates. This paper reports on the availability of the said collections to the community of researchers studying invertebrates. The accessioned collections were assessed in terms of their taxonomic scope, geographical range, and chronological breadth. A total of 4,238 accessioned specimens are in the Museum, which is composed of 1,108 non-insectan arthropods, 1,149 cnidarians, 178 echinoderms, and 1,803 mollusks. The insect specimens, all of which do not have any accession numbers, are yet to be curated. A total of 1,185 species belonging to 621 genera are found in the collections. The Museum’s sampling activities were greatest in the western part of the Philippines, specifically in Puer to Galera, Oriental Mindoro. Much of the Eastern regions in the Philippines are yet to be sampled, particularly the terrestrial habitats. Prolific museum contributors include Francisco Nemenzo, Sr. (709 specimen lots), Neon Rosell (327 specimen lots), and Fernando Dayrit (233 specimen lots). At present, plans for collection expansion is underway, to encourage collaborative research with other natural history museums.

Brachyuran crabs belonging to the subfamily Ethusinae Guinot, 1977, family Dorippidae MacLeay, 1838, are adapted to carry bivalve shells or other objects on their backs by using the hooked dactyli of their last two pairs of pereopods (P4 and P5), which are dorsally located and mobile. Most species inhabit deep water and are infrequently collected. The taxonomy of the 57 known Indo-West Pacific species of ethusines is revised. The subfamily consists of three genera: Ethusa Roux, 1830, with 30 species of which four are being described as new, Ethusina Smith, 1884, with 25 species of which eight are new, and Parethusa Chen, 1997, with two species of which one is new. Ethusa and Ethusina are worldwide in distribution while Parethusa is exclusive to the Indo-West Pacific region. Seven nominal species described by other authors were found to be junior subjective synonyms of other species: Ethusa major Chen, 1993, of Ethusa orientalis Miers, 1886; Ethusa makasarica Chen, 1993, of Ethusa hirsuta McArdle, 1900; Ethusa madagascariensis Chen, 1987, of Ethusa zurstrasseni Doflein, 1904; Ethusina investigatoris (Alcock, 1896) and E. alcocki Ng & Ho, 2003, of Ethusina robusta Miers, 1886; Ethusina insolita Ng & Ho, 2003, of Ethusina dilobotus Chen, 1993; and Ethusina saltator Ng & Ho, 2000, of Ethusina paralongipes Chen, 1993.

Eight species of deep-water porter crabs of the family Homolidae are recorded from Papua New Guinea from three MNHN-led cruises to these waters: Homola orientalis Henderson, 1888, Homola coriolisi Guinot & Richer de Forges, 1995, Homolomannia sibogae Ihle, 1912, Homolomannia occlusa Guinot & Richer de Forges, 1981, Paromolopsis boasi Wood-Mason in Wood-Mason & Alcock, 1891, Lamoha woodmasoni n. sp., Ihlopsis multispinosa (Ihle, 1912) and Latreillopsis gracilipes Guinot & Richer de Forges, 1981. Most are new records for the country, Lamoha woodmasoni n. sp. appears to be the Pacific sister species of the Indian Ocean L. longipes (Alcock & Anderson, 1899). The old records of the latter species from the Solomon Islands are now referred to the new species. The taxonomy of the other species is also discussed.

The tropical to subtropical squat lobster Uroptychus naso Van Dam, 1933 (Chirostylidae) is a widely distributed species originally described from Indonesia, subsequently reported from the Philippines, Taiwan, Japan and it has recently been discovered on the continental slope of north-western Australia. Populations of U. naso occur along the Indo-Pacific Ocean continental margin crossing the recently proposed marine analog of Wallace's line, responsible for past population fragmentation and ancient speciation. Sequence data from mitochondrial (COI, 16S) and nuclear (H3) DNA regions were used to assess genealogical relationships among geographically disjoint populations of the species throughout its known distribution range. Several mitochondrial lineages, corresponding to geographically isolated populations and three cryptic species were encountered, namely, U. naso sensu stricto and two new species. Uroptychus cyrano and Uroptychus pinocchio spp. nov. U. pinocchio is encountered only in Japan, Taiwan and the Philippines; U. cyrano is confined to north-western Australia; and U. naso consists of three genetically distinct populations distributed on both sides of the marine Wallace's line. Fossil-calibrated divergence time approximations indicated a most recent common ancestor (MRCA) for U. naso and U. cyrano from early Eocene whilst northern and southern populations of the former have been separated probably since the Miocene. These patterns may represent a standard distribution trend for several other deep-sea invertebrate species with similar geographical ranges. (C) 2011 Elsevier Inc. All rights reserved.

Seguenzioidea and Trochoidea are substantial parts of the biodiversity in the Indo-Pacific. While many Japanese, Australian, New Caledonian and New Zealand species have been studied and described recently, these superfamilies remain unsatisfactory known in the Philippines. Modern collecting resulted in the discovery of many new species. Others are well presented in collections worldwide but most often they bear names of mainly Japanese species, occasionally of Australian or Indian Ocean species. These names have been used as "megaspecies-names" for a vast part of the Indo-Pacific mollusca. We here document 178 species collected in the Philippines, either by Conchology, Inc. Or the Museum National d'Histoire Naturelle, Paris (hereafter referred to as MNHN). The first author is a fan of Trochidae since three decades, from where this publication, which is the result of three years collecting by hundreds of fisherman, scientists and divers. We therefore enlighten this book with photographs of the area, the events, living animals and the people.

Material close to Naxioides robillardi (Miers, 1882), obtained recently from French Polynesia between 90 and 400 m is compared with numerous specimens from the Indo-west Pacific. Two new species are described, one from the Society Islands, the other from the Marquesas. The synonymy between Naxioides mammillata (Ortmann, 1893) and Naxioides robillardi (Miers, 1882), by Griffin (1974), is adopted, with the distinction being made between two forms corresponding to the species of Miers and Ortmann: viz. N. robillardi forma typica, and N. robillardi forma mammillata. A new synonymy is recognized between Naxioides elegans (Miers, 1886) and Naxioides robillardi (Miers, 1882).

Based on the material obtained from the waters of the tropical Western Pacific (Philippines, New Caledonia, Vanuatu), three “large-eyed” species of Grammatonotus are redescribed: G. ambiortus, presumably widely distributed along island arcs in the western and central parts of the Pacific Ocean; G. cf. macrophthalmus from the waters of New Caledonia (new finding, but the specimens do not fully correspond to the original description, based on the fish caught at the Kyushu-Palau Ridge); and G. crosnieri, apparently endemic species in the Philippines waters. Clear diagnostic differences between these species were established, the structure of the caudal fin of G. ambiortus was described for the first time, and it turned out to be specific within the genus; the importance of individual morphological features in species diagnostics is discussed.

Mollusks are an invaluable resource in the Philippines, but recent reviews on the status of museum collections of mollusks or research trends in the country are lacking. Such assessments can contribute to a more comprehensive evaluation of natural history museums in the Philippines, as well as biodiversity management. This review showed that local museums in the Philippines have much to improve in terms of their accessibility and geographic coverage in order to effectively cater to research and conservation needs of the country. Online access to databases was lacking for local museums, making it cumbersome to retrieve collection information. The UST museum held the most species and subspecies across all museums (4899), comparable to the national museums of countries such as the USA and France. In terms of size, there were larger Philippine mollusk collections in museums abroad. Majority of mollusk specimens come from Regions 4 and 7, while the CAR and Region 12 were least sampled. Publications on Philippine mollusks are dominated by taxonomic and biodiversity research. Around 80% of publications were on marine species. Therefore, there is a great need to (1) improve access to collections by publishing databases and collections online; (2) improve spatial coverage of mollusk sampling to have a better nationwide (and habitat) representation of Philippine mollusk diversity; (3) fill important knowledge gaps in the ecological assessment of exploited mollusks and minor taxa that will be useful in status assessment and management; and (4) build a network of functional museums to facilitate mollusk and invertebrate researches and conservation by making properly curated specimens available to more researchers nationwide.

The genus Phylladiorhynchus Baba, 1969 currently contains 11 species, all occurring in the shallow waters and on the continental shelf of the Indian and Pacific oceans. Recent expeditions in these oceans have resulted in the collection of numerous new specimens in need of analysis. We have studied this material using an integrative approach analysing both morphological and molecular (COI and 16S) characters. We describe 41 new species and resurrect three old names: P. integrus (Benedict, 1902) and P. lenzi (Rathbun, 1907), previously synonymized with P. pusillus (Henderson, 1885), and P. serrirostris (Melin, 1939), previously synonymized with P. integrirostris (Dana, 1852). Most species of the genus are described and illustrated. Some species are barely discernible on the basis of morphological characters but are highly divergent genetically. Species of Phylladiorhynchus are mainly distinguishable by the number of epigastric spines and lateral spines of the carapace, the shape and the armature of the rostrum, the number and pattern of the ridges on the carapace and pleon, the shape of thoracic sternite 3 and the armature of the P2–4 dactyli. A dichotomous identification key to all species is provided.

The MUSORSTOM Expedition has gathered stalked Crinoids (family: Isocrinidae) belonging to the two genera Metacrinus and Saracrinus. Four species are described here, M. musorstomae is a new one. The validity of the genus Saracrinus is confirmed. The organization of the skeleton is analysed. It shows some aspects of the evolution of the Isocrinidae. Metacrinus and Saracrinus present several primitive characteristics. The study of the MUSORSTOM specimens permits a review of our knowledge about recent and fossil Isocrinidae. The recent representatives of this family are more hightly diversified than the fossil one. It becomes apparent that Metacrinus and Saracrinus are two young taxa at the outset of their adaptative radiation.

A review of species of the deep-sea sponge-associated shrimp genera Spongicola de Haan, 1844 and Paraspongicola de Saint Laurent & Cleva, 1981 (Decapoda, Stenopodidea) is presented on the basis of rich collections made by French expeditions in the Indo-West Pacific, supplemented by collections preserved in various institutions in the world. Seven species are recognized in Spongicola, of which three are new to science: S. venustus de Haan, 1844, S. andamanicus Alcock, 1901, S. levigatus Hayashi & Ogawa, 1987, S. parvispinus Zarenkov, 1990, S. depressus n. sp. from Loyalty Islands, S. goyi n. sp. from Japan, Indonesia, New Caledonia and Vanuatu, and S. robustus n. sp. from Mauritius and Mozambique. Subspecific division of S. andamanicus Alcock, 190 1, proposed by de Saint Laurenr & Cleva (198 1), is abandoned, since our morphological analysis strongly suggests that the division does not reflect a population structure of the species; S. holthuisi de Saint Laurent & Cleva, 198 1, is also reduced to a junior synonym of S. andamanicus. Two species are recognized in Paraspongicola, both previously described, viz. P. pusillus de Saint Laurent & Cleva, 1981 and P. inflatus (de saint Laurent & Cleva, 198 1) n. comb., of which the latter is here transferred from Spongicola. Keys in aid for identification are provided for each genus. Geographic and bathymetric distributions of species are briefly discussed. Association with host sponges was verified for some species.

A species group hitherto concealed within Chlorophthalmus (Chlorophthalmidae) is described as a new family and genus of Aulopiformes, Paraulopidae and Paraulopus, respectively. Paraulopus clearly belongs in Aulopiformes owing to an enlarged uncinate process on the second epibranchial, the absence of a swimbladder, and fusion of the medial processes of the pelvic girdle, but characterized by having the following combination of characters: the fourth basibranchial with a long tail but no gap separating fourth basibranchial and fifth ceratobranchial, epipleural bones distributed from posterior portion of abdominal vertebra to anterior portion of caudal vertebra, and flesh specimens of most species with paired olive spots dorsally on body. The phylogenetic position of Paraulopus is defined by a cladistic analysis of 101 morphological characters, in 21 genera of Aulopiformes. In a single most parsimonious tree, Paraulopus and Chlorophthalmus are in two different major clades, there being four major clades in all, roughly corresponding to the four suborders of Aulopiformes. Paraulopidae is included in the suborder Synodontoidei. In addition, Bathysauroides is transferred to Chlorophthalmoidei from Giganturoidei, and Bathysauroides and Bathysauropsis are elevated to familial status.

New data on the scaphopod fauna of the Indo-West Pacific are presented, based on new material from recent oceanographic expeditions, mostly in the SW Indian Ocean, SE Asia and the New Caledonia region. Over 780 stations yielded a total of 139 species. Of 81 species of Dentaliida and 58 Gadilida, 42 species (16 Dentaliida and 26 Gadilida), as well as 3 gadilid genera, are described as new. Many range extensions are documented, and new synonymies are established. With 73 recorded species, New Caledonia is currently the geographic area with the highest documented scaphopod diversity. Their bathymetric distribution shows a peak in species numbers in deep water around 800 m, with a second, minor peak for Gadilida at around 2,000 m. Including genera not represented in the Indo-Pacific, 44 Recent scaphopod genera are recognized. The radula of 42 of these is described, and an update of the general classification of the class Scaphopoda is proposed.

A cladistic analysis of Neoglyphea inopinata Forest & de Saint Laurent, 1975, clearly reveals that it possesses both of the diagnostic apomorphies for the fractosternalian Reptantia, the fractured or articulated sternum between the seventh and eighth thoracic somites, and the tripartite secula. Furthermore, there is a distinctive epistome form that is otherwise seen only in the freshwater Astacida. These features have implications for the eventual modification of the higher taxonomy and our ideas concerning the evolution of Reptantia.

A compiled list of Fiji Islands chitons, including an updated chresonymy list and identification key, is provided. To the nine species previously known from the literature ten more are added. Of the 19 species now known from Fijian waters, one is a deep-water species and two are also known from fossils. A redescription of Callochiton neocaledonicus Kaas & Van Belle, 1990, and a detailed description of subadult specimens of Choneplax littlerorum Sirenko, 2003 are herein provided. Chiton spinosetatus Bergenhayn, 1930 is here regarded as a synonym of Chiton subassimilis Souverbie in Souverbie & Montrouzier, 1866. A lectotype designation is herein made for one of the numerous syntypes of Cryptoplax jugosus Bergenhayn, 1930 and for one of the two syntypes of Chiton reticulatus Nierstrasz, 1905 to stabilize the type localities for these species. For the same reason, and to clarify the confusing type status of Lepidopleurus niasicus Thiele, 1906, a lectotype is also selected from the three available syntypes. Acanthopleura nigropunctata Carpenter, 1865 and Tonicia novemrugata Bergenhayn, 1930, formerly placed in Tonicia, are both reassigned to the genus Lucilina on the basis of radular differences of both genera (second lateral tooth quadricuspid in Lucilina vs. unicuspid in Tonicia) and the geographic isolation of the Tonicia, of which species occur in central and south American waters only.

This study investigated the taxonomy and distribution of the deep-sea polyplacophoran mollusc Nierstraszella Sirenko, 1992 in the Indo-West Pacific, based on a collection of 516 specimens collected in the Philippines and Solomon Islands. Although seven species names have historically been proposed in this group of chitons, all have been considered as synonyms of the monotypic N. lineata (Nierstrasz, 1905). Morphological examination of this new material reveals the presence of two species. N. lineata is distinct from N. andamanica (Smith, 1906), based on morphological characters given in the original species description and very distinctly different morphology of aesthete pores in the shell surface. Furthermore, populations of N. andamanica in the Philippines and Solomon Islands are locally colonized with the epibiotic (ectoparasitic) bryozoan Pseudobathyalozoon profundum d'Hondt, 2006. These bryozoans attach ventrally to the girdle of the host chiton and the erect zooids feed within the pallial cavity, among the chiton's gills.

Chitons of the order Lepidopleurida are a regular, and sometimes abundant, component of deep-sea faunas associated with sunken wood and other plant debris. Eleven species are known from off New Caledonia (6 species) and Vanuatu (10 species), at depths between 110 and 2340 m. These show discrete bathymetric segregation, but up to three species of Leptochiton may cooccur in the same haul. Five new species and one subspecies are described: Leptochiton boucheti sp. nov., L. deforgesi sp. nov., L. vanbellei sp. nov., L. saitoi sp. nov., L. thandari sp. nov., and Ferreiraella xylophaga karenaessp. Novo Beside sunken plant remains, species of Leptochitonidae are known from reduced environments, both in shallow and deep water, and it is open to speculation whether sunken wood represent the ancestral habitat from which the family radiated, or whether sunken wood represents a secondary habitat that was invaded sometime during the Mesozoic.

Several hundred species of turriform gastropods (Drilliidae, Turridae, Conidae) have been collected at bathyal depths in New Caledonia and other South-West Pacific archipelagoes. Seventeen new species are here described in the genera Drillia (Drilliidae), Inquisitor, Funa, Zemacies, Comitas (Turridae), Benthofascis, Bathytomq Glyphostoma, Daphnella, Spergo, Gymnobela, Teretiopsis, and Rocroithys gen. Novo (Conidae). The genus Zemacies, until now known from Paleocene to Pliocene deposits in New Zealand and Australia, is recognized for the first time in the Recent fauna, and includes Z. excelsa sp. Novo from New Caledonia, and Z. queenslandica (Powell, 1969) comb. nov., from Queensland to Papua. Benthofascis lozoueti sp. Nov., from the Norfolk Ridge, is the second confirmed species of the genus. Bathytoma boholica Parth, 1994 is synonymized with B. atractoides (Watson, 1881), and the validity of B. hedlandensis Tippett & Kosuge, 1994 is questioned. The range of Spergo fusiformis (Kuroda & Habe, 1961), hitherto known only from Japan, is shown to extend to Madagascar and the South-West Pacific. Daphnella itonis, which has been known under that name in the Japanese literature for more than 40 years, is formally described for the first time, based on specimens from New Caledonia. The species has very long radular teeth and, like molluscivorous species of cones, appears to be feeding on gastropods.

A new species of the crab genus Cosmonotus Adams & White in White, 1848, Cosmonotus mclaughlinae n. sp., is described from the Indo-West Pacific Ocean. This new species inhabits coarse sand and shell bottoms between 75 and 369 m and is so far known from La Réunion, Philippines, Indonesia (Kai Islands), Salomon, Futuna, Vanuatu, Loyalty Islands (Lifou), Fiji, Tonga (N Ha’apai Group). This new species is morphologically close to C. genkaiae Takeda & Miyake, 1970, from which it is easily separated by: 1) the carapace covered by squamiform tubercles (instead of long striae); 2) the lack of the median rostral process (instead of being present and short); 3) the dorsal carpal face of chelipeds with rounded tubercles (instead of striae); and 4) the slender, eyestalks (instead of stout).

This is part of a series of papers (TAVARES, 1991a, 1991b, 1992a, 1992b, 1992c) reviewing the Cyclodorippidae Ortmann, 1892, and Cymonomidae Bouvier, 1897, of the world. It contains a review of all the Cyclodorippidae from the Indo West Pacific as well as one genus of Cymonomidae. This is a systematic approach preceding a more detailed study of the Cyclodorippoidea morphology and of the phylogenetic relationships within the superfamily. The present work was based upon large collections from the Indo-West Pacific (Madagascar, Japan, Vietnam, Philippines, Indonesia, Australia, Chesterfield Islands, New Caledonia, Loyalty Islands, and Wallis and Futuna Islands) carried out by the following French expéditions : MUSORSTOM 1-7, BIOCAL, CHALCAL 2, CORAIL 2, KARUBAR, LAGON, and SMIB 6. Also included is the material collected by the "Siboga" Expédition, 1899, CRUSTACEA DECAPODA : CYCLODORIPPIDAE ET CYMONOMIDAE 255 "Albatross", 1908, the material collected by the Russian océanographie ships "Orlik" in 1960 on the coast of Vietnam and "Vytiatz" on the west coast of Australia, two samples made by Raoul SERÈNE in Indonesia in during the RUMPHIUS I expédition in 1973 and RUMPHIUS IV in 1975, as well as collections made by the Australian ship "Soela" in 1984 on the north coast of Australia, and others made during the expédition CiDARis I under the auspices of the James Cook University on the Great Barrier Reef. Additional material from the collections of The Natural History Muséum (British Muséum), London ; Museum of Comparative Zoology, Massachusetts ; Zoological Museum of Moscow University ; National Science Museum, Tokyo; Northern Territory Muséum of Arts and Science, Darwin ; Queensland Museum, Brisbane ; South African Museum, Cape Town ; National Museum of Natural History, Smithsonian Institution, Washington and Zoologisch Museum, Amsterdam was also examined. Because of insufficient original descriptions, the re-examination of all type specimens [except for Tymolus truncatus (Ihle, 1916) which is apparently lost and Genkaia gordonae Miyaké and Takeda, 1970] and most of the spécimens cited in the literature, was required to properly establish the correspondence between species and the names introduced in the literature.Until now, seven gênera (Tymolus, Corycodus, Xeinostoma, Genkaia, Krangalangia, Ketamia, and Cymonomus) and23 species of Cyclodorippidae and Cymonomidae were known from the Indo-west Pacific. They are as follows : Cyclodorippidae : Tymolus japonicus Stimpson, 1858, T. uncifer (Ortmann, 1892), T. dromioides (Ortmann, 1892), T. similis (Grant, 1905), T. truncatus (Ihle, 1916), T. brucei Tavares, 1991, Corycodus disjunctipes (Stebbing, 1910), Xeinostoma eucheir Stebbing, 1920, Krangalangia rostrata (Ihle, 1916), K. spinosa (Zarenkov, 1970), Ketamia depressa (Ihle, 1916), Genkaia gordonae Miyaké and Takeda, 1970. Cymonomidae : Cymonomus valdiviae Lankaster, 1903, C. andamanicus Alcock, 1905, C. indicus Ihle, 1916, C. trifurcus Stebbing, 1920, C. japonicus Balss, 1922, C. curvirostris Sakai, 1965, C. aequilonius Dell, 1971, C. bathamae Dell, 1971, C. delli Griffin and Brown, 1976, C. umitake Takeda, 1981, C. hakuhoae Takeda and Moosa, 1990. From this study : — Two new genera (Phyllotymolinum and Elassopodus) and 11 new species of Cyclodorippoidea are herein described : Cyclodorippidae : Corycodus merweae, C. decorus, Xeinostoma richeri, X. sakaii, Krangalangia orstom, Ketamia handokoi, K. limatula, K. proxima, Genkaia keijii, Phyllotymolinum crosnieri. Cymonomidae : Elassopodus stellatus. — Two species are resurrected : Corycodus bouvieri Ihle, 1916, from the synonymy of C. disjunctipes (Stebbing, 1910) and Krangalangia spinosa (Zarenkov, 1970) from the synonymy of A", rostrata (Ihle, 1916).— Four lectotypes are designated here for the following species : Corycodus disjunctipes, Xeinostomaeucheir,Krangalangia rostrata, and Ketamia depressa.Presently, a total of 9 genera (7 Cyclodorippidae and 2 Cymonomidae) and 34 species (22 Cyclodorippidae and12 Cymonomidae) are known from the Indo-West Pacific. All these species are studied here except those belonging to the genus Cymonomus which will be treated in a future publication. Keys for families, genera and species are provided as well as illustrations for all species.

Sixty-three Cardiidae species (including Tridacninae) sampled by the 2004 Panglao Marine Biodiversity Project (PMBP) to Panglao, Philippines, and the PANGLAO 2005 Deep-Sea Cruise are described. In addition, Cardiidae species lists of the Philippine Cuming Tour 2005 and AURORA 2007 expedition are provided. Four species are new to science: Fragum grasi spec. nov., Frigidocardium helios spec. nov., F. sancticaroli spec. nov. and Microcardium velatum spec. nov. For the following six species this paper includes the first published records for the Philippines: Acrosterigma dianthinum (Melvill & Standen, 1899), F. torresi (E.A. Smith, 1885), Fulvia (Laevifulvia) subquadrata Vidal & Kirkendale, 2007, Microfragum erugatum (Tate, 1889), M. subfestivum (Vidal & Kirkendale, 2007) and Vasticardium sewelli (Prashad, 1932). Indo-Pacific range extensions for several other species are given. Ecological data support assignment of Afrocardium to Orthocardiinae. Cardium (Ctenocardia) victor Angas, 1872 and Cardium bomasense Martin, 1917 are transferred to Freneixicardia, the former being the sole extant representative of the genus, and of which Cardium (Trachycardium) hulshofi Pannekoek, 1936 is a new synonym. Based on shell morphology, it is shown that the current variously adopted generic assignments of Cardium lobulatum Deshayes, 1855, C. attenuatum G.B. Sowerby 2nd, 1841, C. biradiatum Bruguière, 1789 and C. multipunctatum G.B. Sowerby 1st in Broderip & Sowerby 2nd, 1833 are unsatisfactory. As a consequence, the alleged Indo-Pacific presence of the genus Laevicardium is questionable. Fulvia (Laevifulvia) imperfecta Vidal & Kirkendale, 2007 is a new synonym of “Laevicardium” lobulatum Deshayes, 1855. Habitat preferences of the taxa encountered during PMBP 2004 are defined, based on four main macro-habitat categories. SEM photos, showing the early ontogenetic stages, demonstrate markedly allomorphic growth of some taxa. Description of the process of development to the terminal shell shape provides a more complete species concept and rigorous species delimitation.

Upeneus stenopsis n. sp. is described based on four specimens collected off northern Australia and Quezon Island, Philippines, at depths between 165 to 275 m and compared with four closely related species: the deep-water dwelling Upeneus davidaromi (Red Sea) and U. mascareinsis (Western Indian Ocean) and the shallow Indo-West Pacific species, U. subvittatus and U. vittatus. The new species can be distinguished from all other Upeneus species by a narrow caudal peduncle and a combination of morphometric and meristic characters. This is the first record of a deep-water goatfish of the genus Upeneus from the Pacific. A juvenile Upeneus collected off Quezon at 127–142 m depth was also assigned to the new species and compared to four similar-sized (69–79 mm SL) specimens of U. mascareinsis. A diagnosis is provided for U. subvittatus, along with evidence of its occurrence in the Eastern Indian Ocean and interspecific comparisons. The continued need to screen scientific fish collections for the occurrence of undescribed species that have successfully colonized and adapted to the depth zone surrounding the ocean margin is outlined.

Leptochela Stimpson (1860) is a shallow-water, benthopelagic genus within the predominantly pelagic superfamily Pasiphaeoidea. We inventoried a global fauna of 17 currently valid species of Leptochela and identified a newly discovered eighteenth species. Our analysis combined both morphological and molecular data, using 13 characters (including two multistate characters) and 5 gene markers, respectively. The results revealed incongruence between the molecular and morphological datasets. However, our phylogenetic conclusions were based on a consensus approach, integrating morphological, molecular, and total evidence trees, which revealed three robust clades. We discuss the evolutionary development of quantitative and qualitative morphological traits in Leptochela and explore the potential causes of the incongruence between morphological and molecular signals, particularly in the context of pelagic eucarids transitioning from pelagic to benthopelagic habitats. Additionally, we describe the new species from Madagascar and provide a key to all known species of Leptochela.

Delineating biogeographical regions can provide important insights into the processes shaping large‐scale species distribution patterns. Here we aimed to 1) identify global marine benthic biogeographical regions for ophiuroids extending from shallow waters to the deep sea and 2) quantify the importance of contemporary environmental conditions and geological features in shaping the delineated biogeographical regions. We delineated marine benthic biogeographical regions using a bipartite network analysis applied to a historical dataset of brittle stars. We then examined the faunal exchanges between the regions, and applied random forest models to evaluate the relative role of contemporary environmental conditions and tectonic configuration underlying the proposed biogeographic scheme. We propose ten main large biogeographical regions across the benthos. The biogeographical regions with the highest species richness and endemicity rates were found in the Indo‐Pacific region, Tropical West Atlantic and Southern Ocean, and South America. The key transition regions fall within the subarctic areas of the Pacific and the waters surrounding Southern Australia and New Zealand. Tectonic configuration, surface temperature and salinity were found to be the most important predictors of the ten delineated biogeographical regions. Our biogeographic delineation, including the deep sea, is in partial agreement with those proposed in previous studies. Our results suggest that contemporary environmental conditions (sea water temperature and salinity) strongly influence the modern distribution of ophiuroids, but that plate tectonics left a marked imprint on regional species pools. Future work based on multiple benthic taxa, and with a better understanding of the environmental conditions in the deep sea, are needed to evaluate the robustness of our proposed division.

Based on specimens from the Muséum National d'Histoire Naturelle, Paris, the drilliid genera Splendrillia and Plagiostropha from New Caledonia are revised, and information on species of these genera from other areas is included. A total of 18 species of Splendrillia are examined. Fourteen species are described as new: one from the Philippines and thirteen from New Caledonia (of which two are also recorded from the Mozambique Channel and one from the Philippines). Splendrillia disjecta (Smith, 1888) described from the Persian Gulf, is recorded from the Philippines. Splendrillia persica (Smith, 1888), also described from the Persian Gulf is recorded from New Caledonia. Splendrillia solicitata (Sowerby, 1913) described from Japan is recorded from New Caledonia. Splendrillia praeclara (Melvill, 1893) described from Bombay, India, is recorded from both the Philippines and New Caledonia. Four new species of Plagiostropha are described: three from New Caledonia and one from Réunion Island.

The slipper lobster Chelarctus cultrifer (Ortmann, 1897), a putatively wide-spread Indo-West Pacific species, is well-known in Japan. However, recent collections from Taiwan and the Philippines, and comparisons with material from Indonesia and elsewhere revealed that there are actually two species confused under this name. The two species differ markedly in morphology and colour. On the basis of the lectotype designation of C. cultrifer by Holthuis (2002, from Indonesia), the material from Taiwan and Japan is shown to be actually undescribed and is named herein. Chelarctus cultrifer sensu stricto is restricted to the material from the more southern localities in the Philippines westwards to Iles Glorieuses. Genetic comparison of sequences of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), supported the species separation. The molecular data further suggested that two genetic forms are present within C. cultrifer sensu stricto, and therefore, the subspecific name C. cultrifer meridionalis (Holthuis, 1960) is resurrected.

The commercial deep-sea penaeid shrimp genus Parapenaeus contains 15 species, three subspecies and two forms in the Indo-West Pacific and the Atlantic. Novel nucleotide sequence data from five different genes (COI, 16S, 12S, NaK and PEPCK) were collected to estimate phylogenetic relationships and taxonomic status amongst all but one subspecies in this genus. The phylogenetic results only support two of the four species groups previously proposed for this genus and indicate an evolution direction of the genital organs from simple to complex. The present results suggest that Parapenaeus originated in the shallow waters of the West Pacific with subsequent migration to the deep sea and the Atlantic. The molecular data reveal that there was probably misidentification of females between Parapenaeus australiensis and Parapenaeus ruberoculatus, with females previously assigned as P. australiensis likely being the females of P. ruberoculatus, while material identified as P. australiensis forma nodosa being the true P. australiensis females. On the other hand, Parapenaeus longipes forma denticulata truly represents a variation of the same species, while the subspecies Parapenaeus fissuroides indicus warrants a specific rank.

Recent French expeditions to the Philippines, New Caledonia and Makassar Strait (Indonesia) have resulted in a small collection of hyperiid amphipods representing 11 species. All are tropical or warm temperate species. Megalanceola stephenseni, a rare species, is represented by 8 specimens including some very large females and two males; only one male specimen has been recorded previously. Paratyphis promontorii is a new record for the south western Pacific.

The bathyal zone lies along the slopes of continents and on seamounts and underwater rises. It extends from the edge of the shelf to the beginning of the abyss and is a substantial part of the ocean, being larger than the shallow shelf zone, including the sublittoral. Some taxa of benthic animals attain their optimal number of species and abundance in the bathyal zone. The distribution of the bathyal fauna is described on the basis of groups of species with comparable geographical range, termed geographic faunistic elements or types of range. The Brachiopoda, which have been thoroughly studied from a large database of samples and records, are used to establish clear biogeographical patterns in the bathyal zone of the world ocean. There are depth-related changes within the limits of the bathyal zone: the number of species; the number of geographic faunistic elements; and the number of latitudinal (climatic) faunistic belts diminish with increasing depth. Correspondingly, there is a reduction in number of faunistic provinces. The simplification in biogeographic structure of bottom fauna down the slopes is in accordance with the simplification in the structure of the water masses that are in contact with the bottom along the slopes. Food supply is also an important factor related to depth distribution of the macrobenthic animals. The basic biogeographical divisions of the bathyal zone become asymmetric under the influence of the unequal distribution of land and water masses on the globe, and in relation to oceanic gyres that cause differences in productivity on the eastern and western sides of the oceans. This inequality results in faunistic differences especially in the number of species in different taxa. The bathyal zone may have acted as a reserve of species for recolonization of the shelves and the abyss between periods of global changes in climate. Partly related to this, the bathyal zone contains many relict species, some of which are the most primitive extant members of their groups. The function of the bathyal zone as a reserve of species is challenged by the consequences of commercial exploitation of the non-sustainable fish and shellfish populations on the upper part of the continental slope and on seamounts.
