This paper is the second result of the study of large collections of Plumularioidea (Cnidaria, Hydrozoa, Leptolida), collected in the seas surrounding New Caledonia, in the Philippines and in Indonesian waters by French expeditions. A total of 13 species belonging to the genera Antennella (five species), Cladoplumaria (one species), Halopteris (four species), Monostaechas (two species) and Corhiza (one species) are described or mentioned in the present report; most of which are illustrated. Three new species, Antennella sinuosa n. sp., Antennella megatheca n. sp. And Corhiza pauciarmata n. sp. are described and another, Halopteris concava (Billard, 1911) is recorded for the first time since the original description. Two species, Antennella sp. and Monostaechas sp. are only identified to the genus level.

This publication is the third in a series of accounts on large collections of Plumularioidea McCrady, 1859 (Cnidaria, Hydrozoa, Hydroidolina) obtained during several French expeditions to the Philippines region, Vanuatu, New Caledonia, Fiji, and the Marquesas Islands. Additional material from Mozambique was also examined and is discussed. A total of 17 species, belonging to the families Kirchenpaueriidae Stechow, 1921 (two species) and Plumulariidae McCrady, 1859 (15 species), are scrutinized and illustrated in the present report. Three new species of the genus Plumularia Lamarck, 1816 are described (Plumularia bathyale n. sp., Plumularia contraria n. sp., Plumularia pseudocontraria n. sp.). The name Plumularia milsteinae n. nom., is proposed for Plumularia spiralis Milstein 1976, a permanently invalid junior homonym of Plumularia spiralis Billard, 1911. Polyplumaria kossowskae (Billard, 1911) is recorded for the first time since its original description. Two species of Plumularia are identified only to the genus level. Type materials of Plumularia habereri Stechow, 1909 and Dentitheca hertwigi Stechow, 1909, and the syntypes of all varieties of Plumularia habereri described by Billard (1913), have also been examined.

One new genus (Schizoplumularia) and three new species (Schizoplumularia vervoorti, S. geniculata and S. elegans) of plumulariids are recognized and described from large collections of plumularioid hydroids collected in New Caledonia and vicinity during several French expeditions. During taxonomic studies of these hydroids, colonies were compared with type material of Plumularia insignis Allman, 1883 and several other similar species-group taxa. As a result, three of the latter (P. flabellum Allman, 1883, P. conjuncta Billard, 1913, and P. billardi nom. nov.) are recognized as valid in addition to P. insignis. The binomen P. billardi is a replacement name for P. insignis var. gracilis Billard, 1913. In being elevated to the rank of species in this work, it becomes an invalid junior primary homonym of several others having the same name.

Species of the bothid genus Arnoglossus collected from waters around New Caledonia are reviewed. Seven species, including two new species, two new zoogeographical records and three species already recorded from the region were identified, being Arnoglossus septemventralis sp. nov. and A. nigrifrons sp. nov., A. tenuis, A. elongatus, and A. macrolophus, A. japonicus and A. polyspilus, respectively. Arnoglossus septemventralis sp. nov., described from ten specimens collected between 230-315 m off southern New Caledonia, is easily separable from all other members of the genus in having seven pelvic rays on both sides. Arnoglossus nigrifrons sp. nov., described from two specimens collected from 300-315 m on the Chesterfield Plateau and northwest of New Caledonia, is characterized by a rounded upper head profile, several anterior dorsal fm rays elongated in males, gill rakers without serrations and a darkened head region. Arnoglossus tenuis, collected from 10-16 m off New Caledonia, was previously known from southern Japan to the South China Sea, and A. elongatus, from 250-350 m off New Caledonia, previously only from the Madura Sea and northwestern Australia. Arnoglossus macrolophus was collected from relatively shallow waters (49-92 m) off New Caledonia, and A. japonicus and A. polyspilus from deeper waters (210-385 m) off New Caledonia, the Loyalty Islands and Chesterfield Plateau.

Five new species of Bolma are described, three from New Caledonia, one from Mozambique and one from French Polynesia, all from deep reef (75-155 m) to bathyal (230-580 m) depths. Four of the new species have been sequenced, and their holotypes are also voucher specimens for COl sequences, thus contributing to a new generation of name-bealing types. The descriptions and names are provided in advance of a forthcoming shell-based revision of the genus Bolma, and in advance of a detailed molecular- and morphology-based study of Bolma in New Caledonian waters.

Six species of the two related bothid genera Tosarhombus and Parabothus from the Coral Sea are described and keys to species are provided: T. neocaledonicus Amaoka & Rivaton, 1991, T. longimanus sp. nov., T. brevis sp. nov., P. filipes sp. nov., P. kiensis (Tanaka, 1918) and P. coarctatus (Gilbert, 1905). T. longimanus is characterized by having uniserial teeth on upper jaw, a pectoral fin on the ocular side longer than the head in males, 6 2 - 7 1 scales in the lateral line and a light brownbody. T. brevis is characterized by having a deeper body, a shorter pectoral fin on the ocular side in males and smaller mouth. P.filipes is distinguished from known congeners of the genus by the greatly elongated pelvic fm in males and the small number of scales in the lateral line. P. kiensis and P. coarctatus represent first records from the Coral Sea.

Several french oceanographie expeditions have permitted to explore the bathyals lope, off the New Caledonia Island (South Western Pacifie), between 300 and 2 900 metres depth. During these recent cruises (Biocal, Biogeocal, Musorstom IV-VI, Smib, Calsub),many stalked Crinoids of different families were sampled, or observed and took in pictures with the help of the IFREMER submarine "Cyana". The New Caledonian Crinoid fauna is relatively abundant but less diversified that the fauna which was collected off the Philippines Islands (Western Pacifie). A first list of this stalked Crinoid fauna (13 taxa identified) is established in this paper with a description of three new species (Metacrinus l evii n. sp., Caledonicrinus vaubani n. sp., Proeudesicrinus lifouensis n. sp.) belonging to two new genera (Caledonicrinus n. gen., Proeudesicrinus n. gen.). Further descriptions are supplied for some taxa (Naumachocrinus hawaiiensis, Gymnocrinus, Guillecrinus).Nevertheless, New Caledonian stalked Crinoid fauna appears to be the most archaic in there cent oceans with close relationship with the fossil fauna of the Mesozoic Mesogean Sea. Many taxa have inneed very ancient affinities. Guillecrinus sp. Is the only living representative of the Paleozoic subclass Inadunata. Proisocrinus ruberrimus, Gymnocrinus richeri, Proeudesicrinus lifouensis have relationships with Jurassic adaptative radiation. Caledonicrinus vaubani is the most archaic (late Cretaceous affinities) and the shallower 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 to the origin of New Caledonia fauna.

Among specimens of sea anemones collected from the tropical western Pacific on cruises under the auspices of the Institut de Recherche pour le Développement (IRD) and the Muséum national d’Histoire naturelle, Paris, are some we identify as Exocoelactis actinostoloides (Wassilieff, 1908). We synonymize under this name the species described as Cymbactis maxima Wassilieff, 1908, and Exocoelactis valdiviae Carlgren, 1928. The first two were described from one specimen each, collected at unspecified depths of Sagami Bay, Japan; the latter was based on five specimens reportedly collected off the coast of East Africa at depths of 741 to 823 m. We examined 23 specimens collected in New Caledonia, the Philippines, and Palau from depths of 175 to 480 m. Thus, we extend the geographical and bathymetric range of this species. These specimens allowed us to resolve discrepancies in the definition of the genus Exocoelactis concerning completeness and sterility of the mesenteries: the stronger partner of the mesenterial pairs may be complete and may be sterile.

Five species of Galatheidae : Alainius crosnieri new genus and new species, Phylladiorhynchus integrirostris (Dana, 1853), P. ikedai (Miyake & Baba, 196S), P. pusillus (Henderson, 188S), and Leiogalathea laevirostris (Balss, 1913), collected from New Caledonia are reported. Phylladiorhynchus antonbruuni Tirmizi & Javed, 1980, is transferred to Munida. Phylladiorhynchus serrirostris (Melin, 1939) is synonymized with P. integrirostris. It is suggested that Phylladiorhynchus caribensis Mayo, 1972, be removed from the genus and eventually placed in a new genus.

Examination of materials collected from Indonesia, New Caledonia and vicinity, now deposited in the Museum National d'Histoire Naturelle, disclosed three additional undescribed species of chirostylids belonging to the Uroplychus spinimarginatus group. The group is now shifted to a distinct genus Uroptychodes. Uroptychus grandirostris Yokoya, 1933, which can be transferred to Uroptychodes, has been a problematic species because of the brevity of the original description and the loss of the type material. However, a recent finding of a specimen, which is in poor condition, very much like the illustration of U. grandirostris by Yokoya (1933: Fig. 29), but different from the description of U. grandirostris given by van Dam (1939) for one of the type specimens, suggests that the type material of U. grandirostris includes at least two species. In this paper a neotype is selected for U. grandirostris. The genus Uroptychodes now contains 10 species. All these species are reviewed and a key to the species of the genus is provided.

Ce catalogue recense les spécimens-types de l'ordre des Gadiformes (sensu Patterson et Rosen, 1989) dans les collections ichtyologiques du Muséum national d'histoire naturelle à Paris (MNHN), du Musée océanographique de Monaco (MOM), de l'Université Claude Bernard de Lyon (UCBL) et du Musée zoologique de Strasbourg (MZS). Plusieurs articles traitant de la phylogénie des Gadiformes sont regroupés dans Cohen (1989). Les Zoarcoidei et les Ophidioidei ont été séparés des Gadiformes (voir Patterson et Rosen, 1989, pour un historique). Les premiers sont maintenant classés dans les Perciformes, les seconds dans un autre ordre de Paracantbopterygies, les Ophidiiformes (Lecointre, 1994: Nelson. 1994). Les catalogues correspondant restent à compiler. Le tableau 1 présente les récentes classifications des Gadiformes que nous avons consultées (Markle in Cohen, 1989; Cohen et al. , 1990; Nelson, 1994). Nous les avons comparées avec celles qui sont données par Eschmeyer (1990, 1998). Elles se recouvrent très largement, abstraction faite du niveau taxinomique des catégories utilisées. Markle les élève presque toutes au rang familial; Cohen et al. Ne distinguent ni les Steindachneriinae ni les Ranicipitinae; par rapport à Cohen et al. (1990), Eschmeyer (1990) incluait les Parabrotulidae dans les Gadiformes ( 1990), mais les place aujourd'hui dans les Ophidüdae (Ophidiiformes) (1998) comme les autres auteurs. Et élève les Phycinae et les Lotinae au rang familial. Néanmoins, la définition des Lotidae et des Phycidae varie d'un auteur à l'autre (Tableau Il). La liste des Gadiformes actuels est en grande partie donnée dans Cohen et al. (1990). Les Gadiformes et les Pleuronectiformes sont les deux grands ordres de Poissons qui n'ont pas été revus par Cuvier et Valenciennes dans leur monumental travail ( 1829- 1849). La liste des exemplaires historiques de l' annexe A comprend seulement des exemplaires conservés en herbier. Provenant de Risso et d' Adan son, ainsi que quelques exemplaires anciens conservés en alcool. Les types d'herbier de Risso avaient été revus par Bertin (1945). Les types des espèces de Macrouridae décrites par Vaillant en 1888 (Expéditions scientifiques du "Travailleur" et du "Talisman") avaient été revus par Bauchot et al. (1972). Nous avons intégralement repris leurs conclusions. Certains des types de Moridae ont été revus par Cohen en 1964 et 1966, et par Paulin en 1989.

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.

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.

Specimens of the genera Mathilda and Tuba from New Caledonia and the Loyalty Islands are studied, and compared with numerous other nominal mathildid species from the Indo-Pacific and Atlantic Oceans. Diversity is high in this region, with several species showing a much wider distribution in the Indo-Pacific than previously ascertained. Mathilda Semper, 1865 is used sensu lato, including Fimbriatella, Granulicharilda, Mathildona and Opimilda. From the study area thirteen species are diagnosed and compared, and several as yet unnamed forms that need further study are also discussed. Four new species are described, and Mathilda fusca (Okutani & Habe, 1981), previously placed in the turritellid genus Orectospira, is recognized as the largest extant member of the family Mathildidae. Tuba Lea, 1833 is also used sensu lato, including Gegania and Tubena, and is represented by two species (one described as new). Twelve Indo-Pacific species previously referred to as Mathildidae are removed from the family: Mathildona cookiana Dell, 1956 (Epitoniidae); Mathilda elegantula Angas, 1871 (Pyramidellidae ?); M. eurytima Melvill & Standen, 1896 (Cerithiidae); M. gracillima Melvill & Standen, 1901 (Capulidae); M. oppia Hedley, 1907 (Rissoidae); M. opulenta Hedley, 1907 (Cerithiidae); M. rosae Hedley, 1901 (Eulimidae); Eucharilda pleurorbis Laseron, 1951, and Opimilda protolineata Laseron, 1951 (Triphoridae); O. porrigata Laseron, 1951 (Cerithiopsidae ?); Dunkeria pulchella A.

Alcithoe aillaudorum n. sp. is the first Alcithoe known outside New Zealand waters; it is however not consider ed a Gondwanian vicariant relict but is probably a recent 'immigrant that dispersed from New Zealand to New Caledonia via the Norfolk ridge. Lyria exorata n . Sp. Is known from Capel and Kelso Banks, two submerged flat plateaus surrounded by abyssal depths in the Coral Sea. L. habei Okutani, 1979 is a new record for New Caledonia. Records of other Lyria are reviewed and summarized. Although the distribution of Lyria in the Western Pacific corresponds rather well with the limits of the Pacific plate, this distribution appears to be a result of constraints in larval biology rather than a reflection of the plate tectonic history of the area.

Calliotectum Dall, 1890, until now a monotypic deep-water volute genus from the Eastern Pacifie, is shown to be a senior synonym of Teramachia Kuroda, 1931 from the Western Pacifie. Pakaurangia Finlay, 1926 (originally Thiaridae; Miocene of New Zealand) and Butonius Martin, 1933 (originally Fusinidae; Neogene of Indonesia) are new synonyms. Ca/liotectum has a fossil record in the Neogene of the Pacifie region (Okinawa, Indonesia, New Zealand and Ecuador), with a total of 5 species. Ali fossi! records are from deep-water facies. Seven Recent species of Callioteetum are recognised, ail from deep water in tropical latitudes. Three species occur in South-East Asia and the Eastern Indian Ocean, at 200-1660 m depth. Of these, C. tibiaeforme is treated as a polytypic species, with C. johnsoni and C. dupreyae considered to be geographical forms. Calliotectum piersonorum sp. nov. and C. egregium sp. nov. are described from the South-West Pacifie at 450-1060 m depth. Single species occur each in the East Pacifie and in the Caribbean.

The new genus Fusulculus, conchologically most similar to Benthobia Dall, 1889 and Zemira H. & A. Adams, 1853, is erected for axially sculptured species of Pseudolividae with shouldered whorls and obsolete labral tooth; the columellar and parietal callus is of very limited extent, and a parietal rib at the adapical end of the inner lip is absent. Two new species, Fusulculus crenatus (type of genus) and F albus are described from bathyal (400-800 m) hard bottoms at tropical and subtropical latitudes in the southwest Pacific. No post-Paleocene species of Pseudolividae are known from the tropical IndoPacific; the habitat of Fusulculus is bathymetrically transitional between those of Benthobia, from abyssal depths, and the various genera from subtidal waters in southern Australia, South Africa and Angola.

Volutomitra glabella n. sp., from off New Caledonia, is the second representative of the genus from the tropical South-West Pacific, where it has been recorded alive on hard bottoms in 258-525 m. Its anatomy is essentially similar to that of other boreal, Antarctic and Australasian species of Volutomitridae. It is sympatric with the V. vaubani species-complex, from which it differs by its larger adult size (17-25 mm), more vividly coloured shell, and larger protoconch (average diameter 1440,um vs average 1030,um in V. vaubani).

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.

One new genus and nine new species of Cancellariidae are described from New Caledonia from depths between 200 and 600 meters. They are: Africotriton adelphum new species, Mirandaphera new genus, Mirandaphera cayrei new species, Mirandaphera maestratii new species, Merica marisca new species, Sveltia rocroii new species, Sveltia splendidula new species, Nipponaphera pardalis new species, Nipponaphera cyphoma new species, and Nipponaphera goniata new species. Africotriton adelphum new species is the first species in that genus known from outside South Africa and Australia. The new genus Mirandaphera is characterized by its broad, non-umbilicate shell with very large crenulated axial ribs, and axial columella. The genus is composed of the new species described herein, Mirandaphera maestratii new species and M. cayrei new species, and two other species: M. tosaensis (Habe, 1961) new combination and M. arafurensis (Verhecken, 1997) new combination, from deep water off Japan and the Arafura Sea respectively. Trigonaphera teramachii Habe, 1961 and Agatrix. nodosivaricosa Petuch, 1979 are transferred to Nipponaphera. New species of Merica, Sveltia, and Nipponaphera are the deepest dwelling known representatives in their respective genera.

Recent deep-sea explorations in the South Pacific have documented around New Caledonia the most diverse fauna of gastropods of the family Volutomitridae anywhere in the world. Fourteen species (nine new, two remaining unnamed) are recorded, all essentially confined to the 250–750 m depth range. The high number of species in the New Caledonia region does not appear to be an effect of sampling intensity, but appears to result from four factors: regional spatial heterogeneity, frequency of hard substrates, syntopy, and a historical heritage shared with Australia and New Zealand, which until now ranked as the major centre of volutomitrid diversity. In the New Caledonia region, volutomitrids show a marked preference for hard bottoms and up to three species may cooccur in the same dredge haul. Many species appear to have extremely narrow geographical distributions within the region (e.g. a single seamount or a single submerged plateau); conversely, Microvoluta joloensis, the only non-endemic volutomitrid present in New Caledonia, ranges from the Mozambique Channel to Tonga.

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.

Fifteen species of Cancellariidae referable to the genera Zeadmete, Admetula, Fusiaphera, Nipponaphera, and Trigonostoma are reported from depths between 200 and 700 m in New Caledonia and other island groups in the southwest Pacific. Twelve are new species: Zeadmete bathyomon new species, Zeadmete physomon new species, Zeadmete bilix new species, Admetula affluens new species, Admetula marshalli new species, Admetula bathynoma new species, Admetula lutea new species, Admetula emarginata new species, Nipponaphera argo new species, Nipponaphera agastor new species, Nipponaphera tuba new species, and Trigonostoma tryblium new species. All the Recent nominal species of Fusiaphera described from localities throughout the Indo-Pacific area Lire considered to be conspecific, the senior name being Fusiaphera macrospira (Adams and Reeve, 1.850), now with ten synonyms. The ranges of Nipponaphera nodosivaricosa (Petuch, 1.979) and Trigonostoma thysthlon Petit and Harasewych, 1987, are extended to the South Pacific.

A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s. (16) and Strictispiridae (2). A diagnosis with description of the shell and radulae is provided for each of these families.

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.

One species of Gibberula, three species of Dentimargo, and one species of Protoginella are described as new from bathyal levels south from New Caledonia.

Thirty five species attributed to Serrata Jousseaume, 1875 are recognized from the bathyal zone of New Caledonia. Four of these, S. beatrix (Cossignani, 2001), S. tuii (Cossignani, 2001), S. stylaster (Boyer, 2001) and S. boucheti (Boyer, 2001), were previously described in other genera, and 31 other species are here described as new. This series of 35 Serrata species from New Caledonia increases fi ve-fold the Recent specifi c diversity recognized in the genus. The diversity of Serrata species from New Caledonia is inferred to be very partially known, based on the fact that 31% of the identifi ed species are represented in the collections by only one specimen and that 51% were collected at only single stations. The important Serrata fauna documented here has an asymmetrical geographical distribution in New Caledonia, the highest diversity of species being found off far southern New Caledonia and on the northern Norfolk Ridge. The Serrata fauna from New Caledonia, the Loyalty Ridge and the Norfolk Ridge appears to be isolated in the southwest Pacifi c, but it has affi nities with several species occurring in the fossil or Recent fauna of Australia and New Zealand. The fossil distribution of Serrata extends from the Eocene of Alabama to the Pliocene of New Zealand. The distribution of the genus in the Recent seems to be restricted mostly to the southern Indo-Pacifi c latitudes from Cape Agulhas to the Tuamotu Islands, with maximum diversity from the Australian Platform to the Norfolk and New Caledonia Ridges. The fossil genera Euryentome Cossmann, 1899 and Conuginella Laseron, 1957 and the Recent genera Deviginella Laseron, 1957 and Serrataginella Coovert & Coovert, 1995 are proposed as junior synonyms of Serrata. Marginella anatina Lea, 1833 is used instead of Euryentome silabra Palmer, 1937 as the valid name for the type species of the genus Euryentome. The fossil genus Strombiginella Laseron, 1957 is placed in synonymy with the recent genus Hydroginella Laseron, 1957. Serrata and Hydroginella do not seem more closely related to each other than they are to Volvarina-Prunum or to the Austroginella and Dentimargo groups. The “Serrata Group” sensu Coovert & Coovert 1995, composed of Hydroginella, Serrata and 3 synonymous genera, is rejected as being a possibly polyphyletic assemblage. The high disparity in the specifi c shell morphologies of Serrata, the frequent combination of features found as typical in Volvarina and Dentimargo in the Recent, the occurrence of many morphological intergrades between these genera since the Mid-Eocene of the western Tethys sea, and the higher specifi c frequency of the plesiomorphic character of a radula with numerous cusps, together suggest that the genus Serrata may be situated near the base of the common stem from which most of the Recent groups of the Volvarina-Dentimargo complex have differentiated.

The anomuran sand crab family Albuneidae sensu stricto was previously known worldwide from 41 validly described Recent species in eight genera and four fossil taxa of the genus Albunea. A worldwide revision is presented based on a comprehensive survey of the literature and examination of more than 1700 specimens representing all known species. The state of taxonomic knowledge regarding the Albuneidae is summarized; the family is divided into two new subfamilies; two new genera and six new species of albuneids are described; and new information on species’ ranges and biology is presented. Additionally, the genera Blepharipoda Randall and Lophomastix Benedict are removed from the Albuneidae and placed in a new family, based in part on characters of the gill formula and morphology. This new family contains six Recent species and one fossil taxon. Although there is some doubt about its hippoid affinities, it is retained in the Hippoidea as the most basal taxon, pending further cladistic phylogenetic analyses. Here and there are people with eyes which can see, minds which can correlate. They say to themselves: ‘‘If the science of the day before yesterday is rejected by the people of yesterday, and that of yesterday by us of today, is it not possible that what we call science now will be rejected by the men of tomorrow?’’ And the bravest of them answer, ‘‘It is possible.’’ Wassily Kandinsky, 1911, Concerning the Spiritual in Art

A single specimen of a small new hippolytid shrimp, captured between 65-120 m off New Caledonia, is described and illustrated. A new genus, Gelastreutes, is designated for its accommodation, indicating its relationship with the genera Gelastocaris Kemp, Latreutes Stimpson and Paralatreutes Kemp. The new species, G. crosnieri, is remarkable for its robust, nighly calcified body and its similarity in general body form to Gelastocaris paronae suggests that it is also probably a commensal species, possibly an associate of sponges.

A small collection of palaemonoid shrimps, mainly Pontoniinae, from New Caledonian waters of over 100 m depth, has been studied and found to represent 27 taxa, including eight new species of Periclimenes, one new species of both Periclimenaeus and Mesopontonia, and three specimens, including a single ovigerous female, representing a new genus, Amphipontonia kanak. Seven species were recorded from New Caledonian waters for the first time. The species of Periclimenaeus, from 370-450 m, represents the greatest depth from which this mainly shallow-water genus has been reported. Two species, a Periclimenes and a Mesopontonia, both new, were found together in association with a hexactinellid sponge host, Phoronema sp., the first reported association of pontoniine shrimps with a hexactinellid host. Another new Periclimenes, with a remarkable pectinate ambulatory dactylus, is also possibly associated with the "living fossil" crinoid, Gymnocrinus richeri. The present study increases to 57 the number of palaemonoid shrimps known from Indo-West Pacific marine waters exceeding 100 m depth, and clearly indicates that these shrimps are quite well represented in deeper tropical seas. A list of the Indo-West Pacific palaemonoid shrimps known from over 100 m depth, with a new key to the deep-water Indo-West Pacific species of the genus Periclimenes is provided.

A collection of 52 species of palaemonoid shrimps from the Muséum national d'Histoire naturelle, Paris, is reported upon. Material is derived principally from the New Caledonian region but also includes specimens from Aden/Yemen, Comoro Islands, western Indian Ocean, Philippines, Indonesia and Wallis Island. Specimens have been collected from intertidal depths to over 600 m. Ten species have been collected from water depths of over 100 m. Two new genera of pontoniine shrimp are designated : Climeniperaeus, for Periclimenaeus truncoideus Chace & Bruce, 1993, and Typtonychus, for a new species, T. crassimanus. The following species are transferred from the genus Typton to the new genus Typtonychus : T. anomalus (Bruce, 1979), T. dentatus (Fujino & Miyake, 1969), and T. dimorphus (Bruce, 1986). These species are probably all associates of Porifera. Six new species of pontoniine shrimp are described. These include Conchodytes philippinensis, from an unknown locality in the Philippines; Mesopontonia verrucimanus, from 184-186 m in the Tanimbar Islands, Indonesia; Periclimenaeus colodactylus, from 20-25 m in New Caledonia, in association with Diplosoma versicolor Monniot; Periclimenes involens, from 92-97 m, off Mindoro, Philippines, of unknown association; Pontonia compacta, from 10- 60 m, in New Caledonia, in association with Pyura albaneyensis Michaelson and Pontonia simplicipes, from 71 m, in the Chesterfield Islands, in association with Pyura nigricans Heller.

Three new species of Tridentella Richardson, 1905 are described from the New Caledonia region. All three species are smooth bodied or largely smooth bodied, and all were collected from the shelf around New Caledonia at depths from 150–760 metres. Tridentella palmata sp. nov. is characterised by pereopod 4 having numerous large robust setae on the carpus and an exceptionally long dactylus (7.0 times as long as proximal width); Tridentella katlae sp. nov. is the only species in the genus with medially united eyes that fill the head in dorsal view; Tridentella magna sp. nov. is the largest species in the genus (36 mm) and can be identified by the head having an anterior submarginal ridge and three submarginal tubercles on the poster margin. Tridentella takedai Nunomura 2006 (off Arasaki, Hokusuka-Shi, Kyushu, Japan) is formally transferred to Alcirona Hansen, 1905, forming Alcirona takedai (Nunomura, 2006) comb. nov.

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 diversification of Indo-Pacific marine fauna has long captivated the attention of evolutionary biologists. Previous studies have mainly focused on coral reef or shallow water-associated taxa. Here, we present the first attempt to reconstruct the evolutionary historyphylogeny, diversification, and biogeographyof a deep-water lineage. We sequenced the molecular markers 16S, COI, ND1, 18S, and 28S for nearly 80% of the nominal species of the squat lobster genus Paramunida. Analyses of the molecular phylogeny revealed an accelerated diversification in the late OligoceneMiocene followed by a slowdown in the rate of lineage accumulation over time. A parametric biogeographical reconstruction showed the importance of the southwest Pacific area, specifically the island arc of Fiji, Tonga, Vanuatu, Wallis, and Futuna, for diversification of squat lobsters, probably associated with the global warming, high tectonic activity, and changes in oceanic currents that took place in this region during the OligoceneMiocene period. These results add strong evidence to the hypothesis that the Neogene was a period of major diversification for marine organisms in both shallow and deep waters.

Six new species of Zygophylax (Z. dispersa sp. nov., Z. encarnae sp. nov., Z. laertesi sp. nov., Z. medeae sp. nov., Z. niobae sp. nov. and Z. pseudoabietinella sp. nov.) are described and figured. The material studied was present in collections from several French expeditions in the western Pacific, mostly in the waters around New Caledonia and vicinity.

The inventory of epibenthic dredgings in the areas of New Caledonia, Indonesia and Wallis and Futuna Islands shows that there are 14 species of Euphausiids, of which Pseudeuphausia sinica is new for this region. Another species, Thysanopoda cornuta, sampling of which is always exceptional, leads the author to report on a closely related species, T. minyops, caught in the South of Madagascar and of which it is the second mention since its description. These two, giant, abyssal species are compared and original morphological features are described. In the Euphausiids, except petasma, modifications of the tegumental parts linked with reproduction only affect the segment bearing the gonopores, the coxae and sternites being involved in both sexes. In the females, the thelycum is a median unpaired specific modification of the sixth sternite articular sheet, partly closed by the coxal fold of the sixth thoracopods. The insertion of the spermatophores and their relation with the orifices of oviducts, situated beneath the coxae, helps in understanding the entirely external functioning of these seminal receptacles. A description of the antennular sensory setae is provided for the deep species Bentheuphausia amblyops.

In numerous samples dredged in the New Caledonian area during many cruises (MUSORSTOM 4, 5 and 6, in particular), 11 species of mysidaceans were caught, 3 of which new to science. Nine belong to the sub-order Lophogastrida : Gnathophausia ingens, G. elegans fagei, Lophogaster manilae, L. neocaledonensis sp. nov., Paralophogasler glaber, P. foresti, P. philippinensis, P. boucheti sp. Nov., and Eucopia australis. Two others belong to Mysida : Petalophthalmus armiger and Hansenomysis carinata sp. Nov. Some original morphological features are provided for a few already known species (such as the description of females of L. manilae), as well as the bathymetrie distribution of species of Lophogaster and Paralophogaster.

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.

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.

Two new species belonging to the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) are described from the western Pacific Ocean. The first belongs to Carcinoplax H. Milne Edwards, 1852, the second to Pycnoplax Castro, 2007. The new species of Corcinoplax is distinguished from the 18 known species of the genus by the morphologies of the first male pleopods and outer orbital and anterolateral teeth; the new species of Pycnoplax is distinguished from the five known species of the genus by the morphology of the first and second male pleopods and the granular carapace. A female specimen of a third goneplacid, Thyraplax truncata Castro, 2007, which was previously known only from male specimens, is also described. The characters of the two new species further confirm that in the Goneplacidae s.s. the morphology of the external reproductive structures rather than that of the carapace are far more reliable in showing phylogenetic relationships among supraspecific taxa.

The present report deals with a collection of 33 species of Nassariidae from New Caledonian waters. Approximately 30 % of the species recorded are new geographical range extensions. Nassarius bifarius (Baird in Brenchley. 1873). Previously considered a synonym of N. Novaezelandiae (Reeve, 1854). And N. stigmarius (A. Adams. 1852). Previously considered a synonym of N. splendidulus (Dunker.,1846). Arc now acknowledged to be valid, separate species Nassarius olomea Kay, 1979 is synonymed with N. crebricostatus (Schepman, 1911). Nassarius (Zeuxis) arcus sp. nov is described and recorded from depths of 95-200 m.

The present study describes a new species of Arcoscalpellum Hoek, 1907, and a new species of Gymnoscalpellum Newman & Ross, 1971, collected by deep-sea expeditions led by the Muséum national d’Histoire naturelle (Paris) in the Coral Sea off New Caledonia, Papua New Guinea (PNG), the Solomon Islands and Vanuatu. Arcoscalpellum epeeum sp. Nov. Differs from all described species of Arcoscalpellum by the presence of a long, sharp, sword-shaped carina, which extends beyond the apices of the terga by 1/3 to 1/4 of their length. The species is dioecious, with large females and dwarf males that are sac-like, lack shell plates and are housed in paired receptacles at the inner edges of the scutal plates. Arcoscalpellum epeeum sp. Nov. Was collected in the waters of New Caledonia and Vanuatu. Gymnoscalpellum indopacificum sp. Nov. Differs from the six currently described species of Gymnoscalpellum by having a very small inframedian latus and a branched upper latus. The species is dioecious, with large females and dwarf males, the latter composed of 4 shell plates and housed in paired receptacles at the inner edges of the scutal plates. The penis of the dwarf males of G. indopacificum sp. Nov. Is about 0.8 of the total length of the male and has five side branches extending out along its length. Gymnoscalpellum indopacificum sp. Nov. Is distributed in the waters of Papua New Guinea, the Solomon Islands and Vanuatu, and represents the first record of this genus in the Indo-Pacific region.

The Indo-West-Pacific material previously identified as Eugonatonotus crassus (A. Milne Edwards, 1881) is found to be distinct from the typical form in the tropical Western Atlantic by bearing an extra pair of spines at the fifth abdominal tergite. The new form, named E. chacei sp. nov., is described and a holotype selected from Taiwanese material. The morphological differences between the two species are listed and discussed and their coloration is illustrated.

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.

Before the present study, Plesionika rostricrescentis (Bate, 1888) and P. lophotes Chace, 1985 were the two Plesionika species unique in having a high basal rostral crest. A recently described species, P. erythrocyclus Chan & Crosnier, 1997 has a low basal rostral crest but is evidently related to P. rostricrescentis. Close examination of the abundant material collected during the MUSORSTOM expeditions and from Taiwan revealed that there are at least eight species in this ‘‘P. rostricrescentis-P. lophotes’’ species complex. These taxa are morphologically very similar but can be distinguished by their very distinctive colorations, which are often striking and consist of large circular spots. In the ‘‘P. rostricrescentis’’ group, which has the dorsal margin of the rostrum unarmed between the anteriormost tooth of the basal rostral crest and the subapical teeth, five species are recognized. Plesionika rostricrescentis is still known only by the holotype from the Kai Islands. Two new species, P. hsuehyui and P. suffusa, closely similar to P. rostricrescentis, are described. Plesionika hsuehyui is widely distributed from Taiwan to Fiji, while P. suffusa has only been found off New Caledonia. Plesionika erythrocyclus, previously known only from Taiwan and French Polynesia, occurs widely in the southern Pacific. Another new species, P. bimaculata, which closely resembles P. erythrocyclus, is distributed off New Caledonia and in adjacent areas. Three species are recognized in the ‘‘P. lophotes’’ group, which bear dorsal rostral teeth between the basal rostral crest and subapical teeth. Plesionika lophotes is restricted to the area between Japan and northwestern Australia. Two further closely similar new species, P. rufomaculata and P. scopifera are described, the former widely distributed from Okinawa to Futuna Island, the latter only off New Caledonia and Tonga. Although coloration is very important in distinguishing these species, species with similar color patterns do not necessarily belong to the same species group. Morphologically, these species are mainly separated by the height of the basal rostral crest, the number of rostral teeth, and the length of the stylocerite and the dactyli of the posterior three pereiopods. However, there is sexual dimorphism in the development of the basal rostral crest in these species, sometimes making positive identification of males and young specimens difficult.

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.

Although O. dorsomaculata and Ocosia apia Poss & Eschmeyer 1975 both share modally XVI, 8 dorsal-fin rays with a long second dorsal-fin spine, and presence of supraocular, lateral lacrimal, and suborbital spines, the former has modally 13 pectoral-fin rays (vs. usually 12 in the latter), a lower modal count of total gill rakers (10 vs. 16–18), greater upper-jaw length, greater third to sixth dorsal-fin spine lengths, the third dorsal-fin spine slightly shorter than the second dorsal-fin spine (vs. third spine markedly shorter than second spine), 1 or 2 prominent pale brown to dark brown blotches on the membrane between the fifth to eighth or sixth to ninth dorsal-fin spines (vs. 1 blotch on the membrane around the third dorsal-fin spine and 1 blotch on the membrane between the sixth to eighth dorsal-fin spines), and body with 11–15 longitudinal pale brown to dark brown bars along lateral line (vs. irregular brown specks).

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.

Twenty nine specimens of the rare deep-sea shrimps Bathypalaemonellidae, just represented until now by few species and specimens (nine species, gathered in only one genus, Bathypalaemonella Balss, 1914) have been collected during different cruises, that occured, on the one hand, in the east Atlantic (Ibero-Moroccan Gulf: BALGIM-84, 1984, and SEAMOUNT 1, 1988; Açores, BIACORES, 1971), and on the other hand, mainly in the Pacific Ocean: Philippines (MUSORSTOM 2 , 1980); Indonesia (KARUBAR, 1991); New Caledonia (BIOCAL, 1985; MUSORSTOM 4, 1985; SMIB 2, 1986; VOLSMAR, 1989; HALIPRO 2, 1996); Vanuatu (MUSORSTOM 8, 1994); Marquesas islands, French Polynesia (MUSORSTOM 9, 1997), and another specimen from the Gulf of Aden (SCIMEROUAD, 1977), that prove to belong to a new species, Bathypalaemonella adenensis n. sp., which can be separated from the seven other species maintained in the genus Bathypalaemonella, by the feature of the scaphocerite (the latero-distal spine overreaches significantly the distal margin of the blade), and of the telson, ended by three pairs of spines. Seven species have been collected: apart from Bathypalaemonella adenensis n. sp., these are: Bathypalaemonella serratipalma Pequegnat, 1970; B. hayashii Komai, 1995; B. cf. humilis Bruce, 1966; B. pandaloides (Rathbun, 1906); B. brevirostris Bruce, 1986; B. pilosipes Bruce, 1986. Bathypalaemonetes n. gen. is established for the last two species mentionned above, Bathypalaemonella brevirostris and B. pilosipes, which can be separated from the species of the genus Bathypalaemonella by a set of features such as: cephalothorax with at the most one postrostral spine; major second pereopod with the ischium shorter than the merus, and its fingers showing a serie of tubercles; minor second pereopod with the dactyl far less shorter than the palm. A key to the genera and species of the family is proposed.

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.

Coelopleurus exquisitus sp. nov. Coppard & Schultz, 2006 occurs at depths of 240 m to 520 m off of New Caledonia in the South Pacific. This new species is distinctive in having large naked interambulacral median regions that are purple with an undulating lavender line, in conjunction with highly curved primary spines that are banded red and pale-green on their dorsal surface for three quarters of the distal length, pointed secondary spines and aboral ophicephalous pedicellariae that have constricted valves.

Species of the bivalve family Lucinidae form a previously unrecognized and signifi cant component of bivalve assemblages at bathyal depths (150-1000 m) in the Indo-West Pacifi c province. Elliptiolucina labeyriei n. gen., n. sp., from 2570 m, is the deepest-occurring lucinid species. South-East Asian seas, from Taiwan to the Arafura Sea, are a hotspot of deep-water lucinid diversity, with 11 species recorded from the Philippines and 14 from Indonesia. Numerous species are in the 20-50 mm range, with several up to 75-80 mm in size, and Meganodontia acetabulum reaches 150 mm. Several species co-occur with representatives of the Vesicomyidae, characteristic of seep and vent communities. It is hypothesized that the lucinid species of this radiation live in discrete pockets of poorly oxygenated sediments enriched in sulfi de by plant debris from nearby land masses and/or diffuse seeping. A parallel is drawn with the “Calcari a Lucina” from the Miocene of Europe. Nine new genera and 32 new species are described.

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.

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.

A new species, Heterocarpus intermedius, confused until now with H. woodmasoni Alcock, 1901, is described after specimens caught off the east coast of Australia, New Caledonia, the Loyalty and the Chesterfield islands, and the Combe and Tuscarora banks. It can be separated mainly by the fact that it has no postrostral crest and only two pairs of dorsolateral spines on the telson. An addition to the indentification key of the Heterocarpus species publishede by Crosnier (1988) 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.

A systematic study of the ctenostome and anascan cheilostome (malacostegan, cellularine, and scruparioid) Bryozoa collected during the recent set of MUSORSTOM cruises has yielded 12 families, 26 genera and subgenera, 51 species and 4 subspecies, mostly from bathyal depths. Only 6 of the species have previously been recorded from New Caledonian waters. The new taxa comprise 1 family (Leiosalpingidae), 3 genera (Candomenipea, Candoscrupocellaria, Astoleiosalpinx), 2 subgenera (Beanodendria, Thaminozoum), 15 species and 4 subspecies. Also newly recorded for the first time from New Caledonian waters are 5 families (4 ctenostomatous), 14 généra (4 ctenostomatous) and 25 species ; 11 of the latter are common to New Caledonia and New Zealand in deeper waters.

The genus Platepistoma Rathbun, 1906, is reviewed and considered ta be valid and not a subgenus of Cancer Linnaeus, 1758. Three new species are described viz. P. nanum, P. kiribatiense and P. seychellense. They are mainly separated on the distinctness of the carapace regions, extent of dorsal granulation of the carapace, and shape of the telson of the male abdomen. The genus is considered to contain seven species, and a key is provided. The name Platepistorna anaglyptum Balss, 1922, is resurrected and the synonymy clarified. Cancer balssii Zarenkov, 1990, is placed in Platepistoma. Cancer (Glebocarcinus) Nations, 1975, is also considered a valid taxon and provisionally allowed to remain as a subgenus of Cancer; it contains at least Cancer oregonensis Rathbun, 1898, and C. amphioetus Rathbun, 1898. Platepistoma is restricted to deeper water, mostly greater than 350 m, in the Indo-West Pacific Oceans, and this is briefly discussed in relation to recent biogeographic theories.

Basal discodorids, with an emphasis on Discodoris and Peltodoris, are revised for the first time. Hundreds od specimens were examined, including all type availables. The individuals variation of morphological characters is evaluated and taken into account for species delineation. Discodorids species are rediscribed based on large numbers of individuals: e.g., 98 individuals were dissected for Sebadoris fragilis (Alder and Hancock, 1864). The nomenclature status (valid name, synonym, nomen dubium) of 125 species names is adressed. Prior to the present study, there were 106 valid names, 13 synonyms, two nomina dubia, three permanently invalid names, one nomen nudum; after revision, there are 39 valid names, 12 synonyms (out of the 13 former synonyms), 25 new synonyms, 27 nomina dubia, three permanently invalid names, one nomen nudum, and 18 names that refer to poorly-know species (which could be nomina dubia, synonyms or valid names). Those numbers confirm again the critical need for taxonomic revisions in order to obtain a reliable knowledge on species biodiversity. Also, the high proportion of new synontyms and new nomina dubia is related to the fact that many discodorids were described based on few specimens (of the 81 Discodoris species names, only five were originally created with more than 4 specimens). Another important factor that explains the high proportion of new synonyms and nomina dubia is the large number of incomplete originale descriptions. The supra-specific relationships of all species considered are addressed based on cladistic analysis. Discodoris is a clade including only two of all the former Discodoris species: Discodoris boholiensis Bergh, 1877, the type species of Discodoris under the ICZN, and Discodoris cebuensis Bergh, 1877. Peltodoris is a clade including only three species: Peltodoris atromaculata Bergh, 1880, the type speces of Peltodoris under the ICZN, Peltodoris mullineri Millen and Bertsch, 2000, and Peltodoris murrea (Abraham, 1877). Also, several species are re-allocated to different discodorid clades: e.g., Discodoris fragilis (Alder and Hancock, 1864) transferred to Sebadoris, Doris raripilosa Abraham, 1877 to Asteronotus, and Discodoris crawfordi Burn, 1969 to Rostanga. However, 50 species (including 21 valid species, 17 nomina dubia, and 12 poorly know species) could not be places in any of the discodorid clades (genera), and therefore are part of a metaphyletic group at the base of Discodorididae. There are 50 species names for which we cannot use a generic name as the first part of the Linnaean binomial. This situation is handled in two ways. First, "Montereina", is used as a genus name for all the species that are part of the metaphyletic group at the base of Discodorididae (the quotation marks indicate that this genus name does not refer to a clade), which is compatible with the ICZN but contradicts phylogenetic principles. Second, the clade name Discodorididae is used as a clade address for those species that cannot be placed in a clade of "generic" rank, which is compatible with the International Code of Phylogenetic Nomenclature (ICPN), or PhyloCode. The use of a supra-generic name instead of a generic name in front of a specific name is implemented in a monographic revision for the first time here, and represents a major change in our nomenclature practices. The vast majority of the species regarded as valid here are efficently delineated based on morphological features (mainly the dorsal color, the shape of the radular teeth, and the reproductive system). However, in a few cases, such as in Tayuva, it seems that species cannot be distinguished morphologically. Future possible studies that could help solve those taxonomic issues are discussed. Seven new species are describes. However, those new species are not formally named for a variety of reasons (mainly because not enough information was available). Finally, many new records are provided, especially from the tropical Indo-West Pacific.

The genus Eumunida, belonging to the family Chirostylidae, is represented in New Caledonia and Chesterfield Islands by seven species, ail of them new to Science : Eumunida keijii, E. sternomaculata, E. annulosa, E. capillata, E. parva, E. minor and E. marginata. Four species (E. sternomaculata, E. annulosa, E. capillata, and E. parva) are very common at depths between 400 and 600 meters, being currently caught at the same stations. The other species are scarce, and hâve been collected either at the same depths (E. keijii), or in shallower waters (E. minor and E. marginata). The high abundance of thèse species could be related to the présence on the bottom of hydrocorallians of the family Stylasteridae. Three species (E. keijii, E. annulosa and E. sternomaculata) belong to the group A after GORDON (1930), characterized by a spine on either side of the sternal segment bearing the chelipeds. The latter two of thèse species hâve a pad on the ventral surface of the palm. E. keijii is closely related to E. pacifica Gordon, 1930, from the south of Timor, but, among other différences, the two are readily distinguished by the size of the first hepatic spine, the médian sinus of the third thoracic sternite and the scales on the sternal segments. E. sternomaculata resembles E. sp., from southeast Australia (E. picta, GORDON, 1930, in part) ; both are nevertheless easily distinguished by the shape of the frontal part of the carapace, the direction of the supraorbital spines and the relative lengths of the anterolateral spines and antennal peduncles. E. annulosa is close to E. sternomaculata. Thèse two species are differentiated by the shape of the rostral spines, the ornamentation of the carapace, the length and shape of the chelipeds and the présence or absence of a disto-mesial spine on the carpus of the chelipeds. E. marginata, E. capillata, E. parva and E. minor belong to the group B, after GORDON, that has no spine on either side of the sternal segment bearing the chelipeds. With the exception of E. parva, ail the other species are provided with a pad on the ventral surface of the palm. E. parva is closely related to E. smithii Henderson, 1883, from the south of Timor, and to E. propior Baba, 1988, from the Philippines. A discussion about the identity of the material of E. smithii from différent expéditions and the relationships between the three species is provided. The maies of thèse three species are characterized by the présence of pleopods on the second to fifth abdominal segments. E. capillata is very close to E. parva, but can be easily distinguished from it by a number of characters. The main différence is the présence of a pad on the ventral surface of the cheliped palm in capillata, and its absence in parva. E. minor is the smallest représentative of the genus. The species is clearly distinguishable from ail the others of the group B by the présence of two prominent spines on the merus of the third maxillipeds, and of four longitudinal rows of spines on the merus of the cheliped. Its closest relative is E. balssi Gordon, 1930. E. marginata is related to E. gordonae Baba, 1973, from Japan. However, the length and the spinulation of the pereopods are very different.

A new genus is porposed for a new species widely distributed in the western Pacific Ocean from the Philippine Islands in the northwestern Pacific south to Kermadec Islands of New Zeland. Jacquesia n. genus, bears considerable similarity to Iridopagurus de Saint Laurent-Dechancé, 1966, in lacking an accessory tooth on the crista dentata of the third maxilliped, but having eleven pairs of quadriserial gills, slender elongate and subequal chelipeds and a well-developed left male sexual tube. It is distinguished from Iridopagurus by he presence of paired fisrt pleopods in females. The new species is a very distinct, but morphologically variable species. Theses variations, however, do not appear to be correlated with either size or sex.

A new right eyed flounder, Samariscus hexaradiatus, is described on the basis of two specimens collected from the Solomon Islands, southwestern Pacific Ocean, at depths of 135-325 m. The new species is distinguished from other species of the genus by the following characters: 6 pectoral-fin rays; 82 dorsal-fin rays and 60-62 anal-fin rays; 9 abdominal vertebrae and 32 caudal vertebrae; presence of ctenoid scales on the interorbital space and high number (74-75) of lateral-line scales. Ocular side of body light brown with four and three distinguishable horseshoe-shaped spots along margins of both dorsal and ventral profiles, respectively. Two indistinct dusky blotches on the lateral line, one situated before the distal end part of the pectoral fin when flattened posteriorly, the other placed near the last one-third of the body length. Two distinct black spots placed on the upper and lower margins of the caudal peduncle at the posterior end of the dorsal and anal fins, respectively. Pectoral fin with dark pigmentation. Dorsal and anal fins dusky brown near the proximal and distal ends of the fin-rays, respectively, and with distinct series of small dusky spots on the medial parts the fin-rays.

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.

The genus Cypraeopsis was so far known from two species in the Miocene of Europe and South-East Asia. An unnamed species is here recorded from the upper Oligocene of France and C. superstes sp. Nov. Is described from the Recent bathyal fauna of New Caledonia and Reunion. C. superstes differs from the fossil species by the body whorl being spirally sculptured, by the outer lip undulating as in Pedicularia, and by the protruding, uncovered protoconch. A character tentatively interpreted as progenetic. C. superstes thus appears paradoxically as an evolved relict.

The Indo-Pacific species of Trivia, Dolichupis and Trivellona are revised, based on the most abundant and comprehensive material ever brought together and reveals a previously unsuspected diversity of Triviinae in the upper bathyal zone (200-500 m) of the tropical West Pacific. The description of this fauna gives an opportunity to reevaluate the validity of numerous species- and genus-group taxa recognized earlier, both in the littoral and deep water zones. The present paper deals with Trivia Broderip, 1837, Decoriatrivia Cate, 1979, Dolichupis Iredale, 1930, and Trivellona Iredale, 1931. A forthcoming study will deal with Trivirostra Jousseaume, 1884, Cleotrivia Iredale, 1930, and Semitrivia Cossmann, 1903. By First Reviser action, Ellatrivia Iredale, 1931 is given precedence over Fossatrivia Iredale, 193 I . Decoriatrivia is treated as a subgenus of Trivia; Dolichupis is regarded as generically distinct from Pusula; the nominal genus Pseudotrivia is synonymized with Trivellona. Trivia (T.) cylindrica sp. novo from the Philippines, and Trivia (T.) vitrosphaera sp. nov., from New Caledonia, represent the first records of Trivia (T.) in the Indo-Pacific. Their deep-water occurrence contrasts with that of the six or so species from the littoral of the temperate and tropical eastern Atlantic. Dolichupis malvabasis sp. nov., a deep water species from the Philippines, is closely related to the type species and sole other representative of Dolichupis, D. producta (Gaskoin, 1836). Nine named and six new species are recognized in Trivellona: T. bulla sp. nov., T. conjonctiva sp. nov., T. oligopleura sp. nov., T. syzygia sp. novo and T. galea sp. nov., all from New Caledonia, and T. eglantina sp. novo from the Philippines. Trivia valerieae Hart, 1996 [= Erato tetatua Hart, 1996, syn. Nov.; First Reviser] is treated as a SW Pacific subspecies of T. paucicostata (Schepman, 1909); T. Shimajiriiensis McNeil, 1961, described from the Pliocene of Okinawa, is now recorded in the Recent fauna of the Philippines. Pusula niasensis Wissema, 1948 is a new synonym of Dolichupis producta (Gaskoin, 1836), Pseudotrivia sagamiensis KUI'oda & Habe, 1971 is a new synonym of T. sibogae (Schepman, 1909), and Fossatrivia suduirauti Lorenz, 1996 is a new synonym of T. speciosa (Kuroda & Cate, 1979). Three nominal species described by Cate (1979) supposedly from the Philippines are shown to be wrongly localized and synonyms of Atlantic taxa: Pseudotrivia samarensis is synonymized with Trivia (T.) arctica (Pulteney, 1799) from Europe, and Pseudotrivia dumaliensis and Niveria (Cleotrivia) aquatanica are both synonymized with Niveria (N) nix Schilder, 1922 from the Caribbean. Decoriatrivia halians Cate, 1979 and D. but'ius Cate, 1979 are both synonymized with Trivia (Decoriatrivia) pauci!irata Sowerby, 1870 from the Panamic Province.

Ten species of Sipunculans collected during a survey of the bathyal fauna of seas off the coast of the Philippines (cruises ESTASE 2 and MUSORSTOM 3) and near New Caledonia (cruises BIOCAL and MUSORSTOM 4) are described and identified. The commonest species in the Philippine collection was Sipunculus robustus and in the New Caledonian Nephasoma diaphanes and Onchnesoma magnibathum. No new species are recorded. Only two species of Echiurians were collected ; the specimens were unfortunately in too poor a state for precise identification.

Four new species of Halgerda from the deep western Pacific Ocean are described. Halgerda fibra n. sp. was found in the Philippines at depths near 90 m and is also recorded from the New Caledonia region in 90-400 m. The new species differs from other Halgerda in its reproductive morphology. The ampulla is larger and more coiled than other Halgerda and the vagina is also much larger and more bulbous than other members of the genus. Halgerda abyssicola n. sp. was found near Vanuatu at depths of 207-280 m and from the Coral Sea in 385-420 m. Its reproductive morphology is unusual for a species of Halgerda in that the penis and vagina are both extremely large and bulbous. Halgerda azteca n. sp. was found near Norfolk Ridge, south of New Caledonia at depths from 230-367 m. Its reproductive morphology differs from other Halgerda species primarily due to its long, coiled ejaculatory duct and prominent vaginal sphincter. Halgerda orstomi n. sp. was found near Vanuatu at depths between 160-251 m; from the Philippines at 92-95 m and from New Caledonia at 120 m. Halgerda orstomi has an unusual vaginal sphincter and bulbous vagina which distinguishes it from other Halgerda species. The ranges and depths of three additional, previously described Halgerda species: H. brunneomaculata Carlson & Hoff, 1993, H. carlsoni Rudman, 1978 and H. dalanghita Fahey & Gosliner, 1999 are also extended.

Two new species of Horaiclavus, lacking radula, venom gland and proboscis, are described. The genus is placed in the subfamily Crassispirinae (Turridae). Both species possess a peculiar foregut structure, the muscular rhynchodaeal outgrowth situated in the rhynchocoel. The possible function of the rhynchodaeal outgrowth is discussed. Other studied species of Horaiclavus possess a radula of a typical ‘crassispirine’ type but lack the outgrowth. The anatomy of the foregut of the new species is superficially similar to that of Zemacies excelsa (Turridae: Zemaciinae), which also possesses an additional structure of the rhynchocoel, namely the ‘pyriform gland’. Conchologically, there is no resemblance between Zemacies and Horaiclavus and it is concluded that similar foregut arrangement appeared independently in both lineages. A new monotypic subfamily Zemaciinae was erected mostly on the basis of the unique foregut arrangement of Zemacies excelsa. We express doubts concerning the importance of these characters in establishing a new taxon of subfamilial rank and therefore the validity of the subfamily Zemaciinae.

The triviid genus Trivellona Iredale, 1931 is distinguished from the other genera within the Triviidae and all 32 known taxa are revised. All recent available informations as weil as the original descriptions and the types were studied and resulted in the description of five species new to science: Trivellona schilderi nov. sp., Trivellona macneili nov. sp., Trivellona catei nov. sp., Trlvellona dolini nov. sp. and Trivellona globulus nov. sp. They are briefly discussed with related forms and with its congeners .. The assumed endemism of several forms of the genus to the bathyal of New Caledonia by Dolin (2001) could not be confirmed as many new findings in the deep water from the Aliguay Island and Balicasag Island, Philippines show a wider distribution th an previously thought This is also true of Trivellona eos (Roberts, 1913) and Trivellona opalina (Kuroda & Cate in Cate, 1979), which are reported for the first time in Philippines waters. The genus Willungia Powell, 1938 is attached as junior synonym to the genus Triviella Jousseaume, 1884 and the decision is briefly discussed.

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.

Crustacea Decapoda Anomura : Revision of the genus Trizopagurus Forest, 1952 (Diogenidae), with the establishment of two new genera. Prior to the present study, the genus Trizopagurus Forest, 1952, included ten species, mostly from the Indo-West Pacific, but two of them from the Eastern Atlantic and one from the Eastern Pacific. Following the examination of about 350 spécimens, this genus has now been revised and two new genera established, Ciliopagurus gen. Nov. And Strigopagurus gen. Nov. In addition 24 species are assigned to the three gênera, 14 of thèse being described as new. After an introduction that discusses the examined material and the methods used in the taxonomic study, a chapter is devoted to the characters that led to the partition of genus Trizopagurus, namely the shape of the cephalothoracic shield, ornamentation of thoracic appendages, organization of the pleopods, and the stridulatory structures. Thèse structures, described and compared in the following chapter, are of particular interest since they can be used to define the three gênera. Their homologies indicate an evolutionary trend from Trizopagurus via Ciliopagurus to Strigopagurus and the three gênera are studied following the order of this cline. The systematic section first gives an account on the current status of the Diogenidae, recently enriched with four gênera. The characters of each genus are tabulated and their comparison used to define some groupings. In most cases, the genera brought together in a same group show marked differentiations and are not closely related. However, the three genera presently studied form a coherent unit, especially on account of the stridulatory structures, which are peculiar and unique, not only within the family, but in ail decapods. An identification key is provided for ail known genera of Diogenidae.The systematic treatment of the three studied gênera comprises references, diagnosis and définitions, together with remarks on the affinities of the included species. Key s for species identification are provided. For each species are given références, a full synonymy, a list of examined material, informations on type spécimens, a description and an account of variations, when enough spécimens are available. In the remarks, the main distinctive morphological features are pointed out and compared with those of related species. Are also mentioned the size distribution by sex, the identified inhabited shells, and the distribution. Trizopagurus Forest, 1952, is characterized by the relatively weak development of the stridulatory elements, which are fewer, less differenciated and grouped in less distinct patches than in the other two genera. The ornamentation of the chelipeds consists of slightly projecting and rounded teeth or tubercles, in front of which short setae (ciliae) are located in semicircular rows. In both sexes, there are four biramous pleopods on the left side of the abdomen, the last one smaller and never oviferous in the female. The three species inhabit shallow water, usually in the tidal zone. T. magnificus (Bouvier, 1898) belongs to the tropical fauna of the eastern Pacific. T. melitai (Chevreux & Bouvier, 1892) and T. rubrocinctus Forest & Raso, 1990, are both from the tropical northeastern Atlantic. In Ciliopagurus gen. Nov., the stridulatory structures are looking like fine, corneous, parallel rods, grouped in several neatly separated patches, which are homologous in the different species. The first three thoracic legs are ornamented by transverse ciliated striae, with much longer setae in some species. There are four unpaired biramous pleopods in both sexes, the last one equal to the others and always oviferous in the female. The species can be separated into two groups, according to whether the ridges on the carpus and propodus of chelipeds, along the transverse striae, are smooth or tuberculated-denticulated. The first group includes eight species : C. strigatus (Herbst, 1804), C. îricolor sp. Nov., C. krempfi (Forest, 1952), C. caparti (Forest, 1952), C. albatrossi sp. Nov., C. shebae (Lewinsohn, 1969), C. macrolepis sp. Nov. Et C. liui sp. Nov. The second group comprises also eight species : C tenebrarum (Alcock, 1905), C. haigae sp. Nov., C. hawaiiensis (McLaughlin & Bailey-Brock, 1975), C. pacificus, C. plessisi, C. major, C. alcocki and C. babai spp. nov. The genus Ciliopagurus, which is widely distributed, includes one species, C. caparti, from the tropical eastern Atlantic. All others are from the tropical Indo-West Pacific, from the Red Sea and southeastern Africa to Japan and the Hawaiian and Marquesas Islands. The bathymetry range is highly variable. In the first group two species are restricted to very shallow water, mostly from the tidal zone. The other ones are distributed from 50 to 120 m, except for the eurybathic C. krempfi, which has been collected between 10 and 300 m. The second group is mostly présent from 120 to 480 m, one species reaching probably a greater depth. The genus Ciliopagurus gen. Nov. Also includes a fossil pagurid from the Middle Miocène, previously known as Dardanus substriatiformis (Lorenthey) and related to the species of the second group.The genus Strigopagurus gen. Nov. Is provided with the most differentiated and accomplished stridulatory structures. They consist of relatively thick corneous rods, arranged in strongly individualized patches, the larger of which appearing as distinctly channelled plates. The carpus and manus of the chelipeds are covered dorsally with strong teeth that end in a thin corneous spine. Thinner corneous teeth are also present on the two following appendages. As usual within the Diogenidae, except Paguristes and Paguropsis, there are no appendages on the first abdominal segment. In the female, the four pleopods are unpaired and biramous, the last one being only partially oviferous. But the second abdominal segment of the maie is usually supplied with a pair of pleopods, which, according to the species, are modified or not as gonopods ; the following three appendages are unpaired and biramous. The five species can be separated into two groups. The first comprises two species without a differentiation of the paired maie pleopods, i. e. S. strigimanus (White, 1847) and S. elongatus sp. nov. The three species with differentiated gonopods, S. bilineatus, S. boreonotus and S. poupini spp. nov. Form the second group. Strigopagurus gen. nov. Is not as extensively distributed as Ciliopagurus gen. nov., being found only from the eastern Indian Océan to Japan and Polynesia. The genus is not strictly tropical, since the two species with undifferenciated pleopods inhabit the southern Australia. One of the other three species is known only from Queensland and another from Polynesia. The last one, present in eastern Indonesia, New Caledonia, the Philippines and Japan, is the only species of the genus spreading north of the Equator. The species of the first group inhabit relatively shallow water, usually from a few to about a hundred meters. The other species are all present at about 250 m, but one of them, the most widely distributed, is still relatively common to 500 m. Finally, a general account of the geographic and bathymetric distribution of genera and species is given and illustrated with maps and a table.

In the present paper we describe the new genus Amiantofusus gen. nov. to accommodate the Atlantic species Fusus amiantus Dall, 1889. The genus belongs to Fasciolariidae and this family is confirmed as distinct from Buccinidae, based on anatomical differences. We add an Indo-West Pacific fauna of seven species described as new to science: miantofusus pacificus sp. nov. (North Fiji Basin, New Caledonia, southern Coral Sea, south West Pacific), A. gloriabundus sp. nov. (North Fiji Basin, Vitiaz Zone), A. sebalis sp. nov. (New Caledonia, Loyalty Islands, Vanuatu), A. candoris sp. nov. (Chesterfield Islands, Fairway), A. maestratii sp. nov. (New Caledonia), A. borbonica sp. nov. (Reunion) and A. cartilago sp. nov. (Mozambique Channel). In addition we add two unnamed species: A. species 1 (North Fiji Basin) and A. species 2 (Vanuatu). Fusus thielei Schepman, 1911 is briefly discussed, the generic placement is still uncertain.

A new species of dragonet, Callionymus petersi from northern New Ireland Province, Papua New Guinea, is described on the basis of five specimens collected with dredges and trawls in about 181–207 m depth from off northwestern New Hanover and off Kavieng. The new species is characterized within the subgenus Bathycallionymus by a short head (3.9–4.3 in SL); eye large (2.1–2.3 in head length); preopercular spine with a long, slightly upcurved main tip, a small antrorse serra followed by two large curved points on its dorsal margin and a strong antrorse spine at its base, ventral margin smooth, slightly concave; first dorsal fin higher than second dorsal fin in the male, slightly lower than second dorsal fin (female), with 4 spines, first spine filamentous (male only); second dorsal-fin high, distally convex (male) or low, distally nearly straight (female), with 9 unbranched rays (last divided at base); anal fin with 9 unbranched rays (last divided at base); 18 pectoral-fin rays; caudal fin elongate (male), the two median rays unbranched, elongate but barely filamentous (male), or distally rounded, without filaments (female); pectoral-fin base with a large dark blotch; sides of body with a series of dark blotches, each of the anterior blotches broken into 2–4 vertical dark streaks; first dorsal fin with a large ocellated black blotch extending over the second and third membranes (male), or mostly confined to the third membrane (female); second dorsal fin pale (male) or spotted with grey; anal fin distally dark (male), with distal dark spots (female); caudal fin with a grey streak in lower section (male), or lowermost membrane black (female). The new species is compared with similar species. Revised keys to callionymid fish species of New Guinea, as well as of the subgenus Bathycallionymus, are presented.

Forty-three species of sertulariid hydroids (Cnidaria: Hydrozoa: Sertulariidae), collected from the tropical western Pacific (Taiwan, Philippines, New Caledonia, French Polynesia, Vanuatu, Fiji, Tonga, Solomon Islands) during various expeditions of the French Tropical Deep-Sea Benthos program, are discussed. Of these, nine are new to science: Gonaxia nova sp. nov., G. plumularioides sp. nov., Sertularella folliformis sp. nov., Se. plicata sp. nov., Se. pseudocatena sp. nov., Se. splendida sp. nov., Se. tronconica sp. nov., Se. tubulosa sp. nov., and Symplectoscyphus paucicatillus sp. nov. The subspecies Symplectoscyphus johnstoni (Gray, 1843) tropicus Vervoort, 1993 is raised to species but, in order to avoid the secondary homonymy with Sy. tropicus (Hartlaub, 1901), the replacement name, Sy. fasciculatus nom. nov., is introduced. The male and female gonothecae of Diphasia cristata Billard, 1920, the male gonothecae of Gonaxia elegans Vervoort, 1993, as well as the female gonothecae of Salacia macer Vervoort & Watson, 2003, are described for the first time. Additional notes on the morphology of several other species are provided. All taxa are illustrated, in most cases using figures drawn at the same scale, so as to highlight the differences between related species.

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 new genus, Ancylodactyla n. gen., is established for two deep water species excluded from Praebebalia Rathbun, 1911, P. elongata Zarenkov, 1969, and P. elata Zarenkov, 1994, and for Randallia nana Zarenkov, 1990, provisionally assigned to Randallia s.s. A study of the extensive collection of leucosiid crabs made by French expeditions to the Indo-Pacific Ocean has increased the known geographic and bathymetric ranges of these species. The new genus is distinguished from Praebebalia and from Randallia s.s. in having male abdominal somites 3-6 fused, and the second male pleopod longer than first pleopod. The species are redescribed, fully illustrated, synonymies are discussed, and a key for their identification is provided.

Thirty-four species of marine bivalve molluscs of the family Lucinidae are described and illustrated from water depths less than 200 m around New Caledonia, the Loyalty Islands and Chesterfield Bank. Most of the bivalves came from three intensively sampled sites: Koumac and Touho on New Caledonia and Lifou in the Loyalty Islands. Eighteen new species are described. Nine new genera (Myrtina n. gen., Poumea n. gen., Solelucina n. gen., Discolucina n. gen., Lepidolucina n. gen., Ferrocina n. gen., Liralucina n. gen., Parvidontia n. gen. And Bretskya n. gen.) include both new and previously described species. Additionally, new descriptions and illustrations of type species are provided for two previously misunderstood genera – Epicodakia Iredale, 1930 and Gonimyrtea Marwick, 1929. The fauna described in this study is the most diverse assemblage of chemosymbiotic bivalves yet recorded.

Knowledge of the little-known cheilostome bryozoan family Petalostegidae has hitherto been based on only two extant species (Petalostegus bicornis (Busk) and P. spinosus Powell), and an Australian Miocene species (P. tenuis (Maplestone)). Previously, these have been included among the anascan superfamily Buguloidea. With the discovery of a remarkably diverse petalostegid fauna in New Caledonian waters (especially on the northern Norfolk Ridge), it is apparent that the family is neither " anascan " nor monogeneric. The obscure monotypic Australian Miocene genus Chelidozoum Stach is now recognised as petalostegid, based on the discovery of four, new. Recent species (including one from off Victoria). Among these species there is a reduction in the size of the costal field from five spines, through three, to two. The known species of Petalostegus Levinsen are redescribed and four new species are described (including one from the New Zealand deep sea). The family, which is entirely southern-hemisphere in distribution, is now included in the ascophorine superfamily Catenicelloidea. Evidence of predation on embryos is seen from boreholes in ovicells of two species of Petalostegus.

The present paper deals with bryozoans in three of the four infraorders of the large suborder Ascophorina (order Cheilostomatida) from MUSORSTOM cruises along the northern Norfolk Ridge and around New Caledonia (including five species from the MUSORSTOM 3 cruise to the Philippines included with the other material). A total of 44 species is recorded (Cribriomorpha : 35 species; Hippothoomorpha : 1 species; Umbonulomorpha : 8 species) of which 22 species are new. A noteworthy feature in New Caledonian waters is the remarkable diversity of two families — the Petalostegidae and Bifaxariidae. Proportionally more species of these families are found here than anywhere else in the world.

The discovery of living species of the predominantly Tertiary catenicellid subfamily Ditaxiporinae on the Norfolk Ridge has necessitated a revision of the subfamily, which is characterised by biseriate multizooidal segments. The type species of the genera of Ditaxiporinae and of the related family Ditaxiporinidae were examined by scanning electron microscopy, leading to the recognition of six genera (two new) and 18 species (four new) and the incorporation of the Ditaxiporinidae into the Ditaxiporinae. The earliest occurring species is Caberoides rockallensis sp. nov. In the late Paleocene of the North Atlantic. There are only two living species - Bryosartor sutilis gen. et sp. Nov. and Plagiopora recens Gordon, both on the northern Norfolk Ridge. A new monotypic genus, Ahcheethamia, is introduced for Caberoides corniculatus Cheetham from the British Eocene. With the exception of two species from North America, the subfamily is clustered in two centres of diversity - northwestern Europe and Australasia, the latter including Caberoides miranda sp. nov. and Plagiopora alma sp. nov., both newly recorded from the Eocene of New Zealand. Thus a Tethyan distribution of the subfamily was achieved relatively early in the Paleogene. Just as in other catenicellids, there seem to have been parallel trends in the Ditaxiporinae in the diversification of the frontal shield from a spinocyst to a perforated gymnocyst on the one hand and with cryptocystal elements (derived from expanded shallow pore-chambers) on the other. A unique development is indicated by the genus Vasignyella. Hitherto included in the family Savignyellidae, Vasignyella appears to have been derived from Ditaxiporina or a common ancestor by reduction to unizooidal segments and the loss of ovicells. A new subfamily of Catenicellidae, Vasignyellinae, is established for tliis genus.

This paper describes a fauna of 98 species of ascophorine bryozoans from 1984-89 MUSORSTOM cruises, mainly in the New Caledonian EEZ. Ten of the species occur solely in the Philippines and some species occur in both regions. The fauna is noteworthy for its endemism (57 of the 84 New Caledonian species, i.e., 68%, are endemic) and its high taxonomic novelty, the latter contributing to a clearer appreciation of the taxonomic limits of some genera and families. Two new families (Phorioppniidae, Buffonellodidae), 54 new species, and 16 new genera are described, mostly from New Caledonia; some, from elsewhere, are the consequence of systematic revision. The new genera are: Xynexecha (Exechonellidae), Parkermavella (Bitectiporidae), Phorioppnia, Oppiphorina, Punctiscutella (Phorioppniidae), Haswelliporina, Mosaicoporina (Porinidae), Wrigiana, Ijimaia (Calwelliidae), Ipsibuffonella, Maiabuffonella (Buffonellodidae), Macrocamera (Eminoeciidae), Pseudoplatyglena (Euthyrisellidae), Richbunea (Celleporidae), Lifuella (Phidoloporidae), and Ptoboroa (Batoporidae). The most speciose family in the collection is the Phidoloporidae, represented by 7 genera and 19 species. The most speciose genus in the collection is, remarkably, the little-known deep sea genus Siphonicytara, with 6 species, all new, which more than doubles the number of species previously described. Ten of the species in the New Caledonian fauna studied here are shared only with New Zealand, and 4 only with the Philippines .

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.

From a brief survey of the literature, it appears that until now only two articles were published during the last century by specialists that are dealing with New Caledonian hydroids. The first was by Redier (1966). From samples collected by Yves Plessis, he described 25 species (including 5 varieties), all already known. Most of them were from the littoral zone and were collected at low tide; a few were from deeper waters (to 40 m depth). The second article was published later on by Vervoort (1993) who studied representatives of the family Sertulariidae in several collections of the Natural History Museum of Paris. The specimens mostly originated from the following oceanographic cruises: Biocal (1985), Lagon (1984, 1985 and 1989), Musorstom 4 (1985), Cha1cal 2 (1986), Biogeocal (1988), Smib 2 (1986), 4 and 5 (1989) and 6 (1990), with two additional sites, a station of the "Vauban" (1978) and a dive of H. Zibrowius (1989). Vervoort recorded 57 species of which 39 were new to Science. Most of the biological material from these cruises came from deep water: only 6 stations were from depths between 28 and 57m, and 77 were from a greater depth (125-860m). More recently, Laboute & Richer de Forges (2004) published a book illustrating the high biodiversity of New Caledonia with many in situ photographs of marine plants and animals. This book includes several pages of beautiful photographs of hydroid colonies, exhibiting part of the macroscopic hydroid fauna observable underwater. It presents interesting illustrations of these animals that are usually little known with divers. Besides, pictures of several species of hydrocorals like milleporids and stylasterids, of pelagic hydroid colonies (Velella and Porpita spp) and of a hydromedusa Aequorea) are also found in this book. From these three publications and from an additional provisional list sent by Bertrand Richer de Forges, the aim for the author was to establish a reliable list of species and to comment on it bearing in mind well known data on hydroids. According to the time dedicated to this project it was not possible to study the entire literature to integrate scattered records from New Caledonia or to discuss additional data related to Pacific hydroids. Moreover, the author never personally studied the New Caledonian hydroid fauna or revised specimens in museum collections: she therefore does not feel responsible of misidentifications that could be found in the list.

The first scanning electron microscopical (SEM) study of a morphologically generalized ascothoracidan crustacean is presented. The extemal morphology of a female Waginella metacrinicola (Okada), ectoparasitic on a pentacrinid stalked crinoid, Metacrinus rotundus Carpenter from Japan, is illustrated using SEM. Several kinds of gland openings on the fiat, ventral side of the carapace are described. The inner wall of the large anteroventral pore on each carapace valve possesses lamellar ridges that bound a large number of small gland openings. Two anterior lattice organs (cardic organs) are found on each valve. The so-called second antenna or antennavestigial eyestalk complex does not arise from the cephalon proper, but from the mantle lateral to the antennule, and it most likely incorporates the extemal part of the organ of Bellonci complex. Records of W. metacrinicola and W. axotremata Grygier infesting metacrinine pentacrinids collected by recent French expeditions to the Philippines and New Caledonia are listed. The former species is reported from Metacrinus musorstomae Roux for the first time, and the latter from M. levii Cominardi, M. serratus DOderlein, and Saracrinus nobilis (Carpenter) for the first time. Waginella axotremata is also reported from northem Australia, infesting S. nobilis, and southeastem Australia, infesting M. cyaneus H.L. Clark. This species apparently uses its raspy, awl-like mandibles, drawings of which are presented herein, to drill ho les in the cirri of its host; such drill-holes are proposed as potential trace fossils for studying the history of crinoid-ascothoracidan associations. The apparent absence of ascothoracidan parasites on other genera of Pentacrinidae suggests that the association may be no older than the Miocene. The possible synonymy of W. metacrinicola and W. axotremata is discussed on the basis of morphology, depth distribution, and biogeography, but is not resolved. Crinoidoxenos Blake, 1933 is revealed as a potential senior synonym of Waginella.

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.

A number of fusinids from the Indo-Pacific deep-water fauna are studied to get more insight in the distribution and variability. The subgenus Chryseofusus (Gastropoda: Fasciolariidae: Fusinus Rafinesque, 1815) is described as new to accommodate a number of species sharing conchological characteristics different from typical Fusinus. Their separation from Fusinus s.s. is based on differences in axial sculpture (usually absent on body whorl), spiral sculpture (weak, close-set, regular, crossed by distinct growth lines), shape (shorter spire, shorter siphonal canal, less convex whorls with subsutural concavity, less constricted suture) and parietal callus (inner lip smooth, parietal wall covered with an extended, adherent thin layer as callus). Fusinus (Chryseofusus) bradneri (Drivas and Jay, 1990), F. (C.) chrysodomoides (Schepman, 1911), F. (C.) graciliformis (Sowerby, 1880), F. (C.) hyphalus M. Smith, 1940, F. (C.) jurgeni Hadorn and Fraussen, 2002, F. (C.) kazdailisi Fraussen and Hadorn, 2000 and F. (C.) subangulatus (von Martens, 1901) are briefly described and their taxonomic placement in the new subgenus is discussed. To avoid further taxonomic complications, a lectotype is designated for the correct F. (C.) chrysodomoides. F. (C.) acherius (west Madagascar, Mozambique Channel, 1475-1530 m), F. (C.) alisae (north New Caledonia, 444-452 m), F. (C.) artutus (Philippines, Bohol, deep water), F. (C.) cadus (south New Caledonia, 460-470 m), F. (C.) dapsilis (Vietnam, deep water), F. (C.) riscus (New Caledonia, Norfolk Ridge, 394-401 m), F. (C.) scissus (south New Caledonia, 535 m), F. (C.) wareni ( New Caledonia, 480 m), and F. (C.) westralis (northwest Australia, off Port Hedland, 450 m) are described as new to science.

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. (Vanuatu, 480-544 m), G. geometricus sp. nov. (Tonga Islands, 427-436 m), G. monsecourorum sp. nov. (Madagascar, 240 m) and G. babae 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.

A survey of the deep-water malacofauna of New Caledonia has brought to light two species referable to the subfamily Columbariinae (Gastropoda: Turbinellidae). Coluzea faeeta sp. nov. is described from off the Isle of Pines at depths of 385-500 m. Additional specimens of Coluzea pinicola Darragh, 1987, previously described from off the Isle of Pines, serve as the basis for the description of the new genus Fustifusus. Serratifusus virginiae sp. nov. And Serratifusus lineatus sp. nov., two recent species of the columbariform genus Serratifusus Darragh. 1969. previously known only from deep-water fossil deposits of Miocene age. Are also described. On the basis of anatomical and radular data, Serratifusus is transferred from the Columbariinae to the family Buccinidae.

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.

Four new muricid species are described from the coral-reef lagoon (25-80 m) of southern New Caledonia: Aspella media n. sp. Is characterized by its reticulated intritacalx and is most similar to A. platylaevis Radwin and D'Attilio, 1976; Maculotriton ingens n. sp., is the second known Maculotriton; it differs from the type species by having a strong intritacalx, a different protoconch, and stronger axial ridges; Typhis carolinae n.sp. Belongs to a small group of Indo-Pacific species only doubtfully referred to T. (Typhina) and Typhis neocaledonicus n. sp. is the third Indo-Pacific species of the predominantly Atlantic subgenus T. (Talityphis).

Seven new muricid species are described from New Caledonia and from the Chesterfield reefs in the Coral Sea. Chicoreus paucifrondosus n. sp. and C. subpalmatus n. sp. are both compared with C. boucheti Houart, 1983; Pterynotus levi n. sp. and P. fulgens n. sp., the first deep-water Pterynotus species described from New Caledonia, are both compared with P. laetifica flemingi Beu, 1967 from New Zealand. Ponderia caledonica n. sp. and P. magna n. sp. are two supplementary species to include in the recently named Ponderia Houart, 1986 and are both compared with the other species of this genus; Muricopsis metivieri n. sp. is related to certain Japanese species tentatively grouped in the subgenus Murexsul Iredale, 1915. All the new species have paucispiral protoconchs.

The New Caledonian species of Typhinae are revised. A total of 11 species are recorded ; 5, all from deep-sea, are new : Siphonochelus (S.) angustus; S. (S.) boucheti; 5. (S.) saitantis; S. (S.) unicornis and S. (? Siphonochelus) undulalus. All the species are described and illustrated together with comparative material. The radulae of 3 species are illustrated : Typhis (Typhina) carolinae Houart, 1987; Siphonochelus (S.) boucheti sp. nov. And S. (S.) saitantis sp. nov. Position and angle of anal tubes are considered to be a good criterion for the separation of species.

The genus Chicoreus Montfort, 1810 is divided into five subgenera : Chicoreus (s.s.) ; Triplex Perry, 1810, Siratus Jousseaume, 1880, Rhizophorimurex Oyama, 1950, and Chicopinnatus n. subgen. Naquetia Jousseaume, 1880 and Chicomurex Arakawa, 1964 are treated as separate genera, due to differences in radula morphology. A new subgenus of Chicoreus, Chicopinnatus is introduced for three species formerly classified in the genus Pterynotus Swainson, 1833. All of the species are systematically revised and illustrated. The Recent species are redescribed and their distributions are mapped. Sixty-three Recent species and one subspecies are recognized : 7 are referable to Chicoreus (s.s.), 39 to Triplex, 2 to Siratus, 1 to Rhizophorimurex, 3 to Chicopinnatus, 5 to Naquetia, and 7 to Chicomurex. One new species is named : Chicomurex protoglobosus. Of the 19 fossil species, 17 are assigned to Triplex and 2 to Chicomurex.

New Caledonian representatives of the muricid subfamily Trophoninae are revised. Two new genera are described and a total of 32 species are recorded, of which 24 are new to science. One species is refered to Apixystus Iredale, 1929, four to Trophonopsis Bucquoy & Dautzenberg, 1882, twenty-two to Leptotrophon n. gen., four to Conchatalos n. gen., and one to Litozamia Iredale, 1929. Two species formerly described in Poirieria (Paziella) (Muricinae) are transfered to Trophoninae. Three species are also known from SE and E Australia, and/or from Indonesia. The others are known only from the New Caledonian region. Most species live between 250 and 775 meters; only one species occurs in 105-110 m and three range deeper than 1000 m.

A new species of Erebonasteridae, Amphicrossus pacificus, is decribed on the basis of a single female from a depth of 155 m north of New Caledonia in the Grand Passage zone. The new species is closely related to Erebonaster spinulosus Humes and for that reason the latter is transferred to the new genus Amphicrossus. Differences in body ornamentation and armature of maxilla, maxilliped and P4 serve to distinguish Amphicrossus and Erebonaster. Other noticeable discrepancies are found in the structure of the rostrum, the shape of the thoracic epimera and the design of the fifth pair of legs. A peculiar structure, the "sensory area", is shown on the posterior surface of enp-2 P2 in both Amphicrossus species which can be differentiated from each other on the basis of differences in antennulary setation, ornamentation of P1-P4 (exopods, intercoxal sclerites) and length: width ratio of anal somite and P5 exopod. The discovery of A. pacificus in the southern hemisphere considerably extends both the depth range and geographicaJ range of the family.

Studies of recent bathyal collections mainly made during MUSORSTOM cruises have shown an extremely diverse grenadier fauna in the New Caledonian region. A total of 932 grenadier specimens (families Bathygadidae and Macrouridae) representing 49 species in 16 genera were collected from 102 samples taken from depths between 395 and 2105 m (mid-depth sounding). Of the 49 species, 15 (31%) were found to be new (one recently described) and two are treated as indeterminate. The collections were dominated by the genera Caelorinchus (14 spp., 5 new), Ventrifossa (7 spp., 2 new, but one not named), Hymenocephalus (sensu lato) (7 spp., 2 new), and Nezumia (5 spp., 3 new). This paper reports the taxonomic findings on the collections. A subsequent paper will report on aspects of the distribution and biology of grenadiers in the New Caledonian region.

A new species of pinguipedid fish, Parapercis nigrodorsalis, is described from 17 specimens collected off the North Island of New Zealand and Wanganella Bank, Norfolk Ridge, Tasman Sea, in depths of 56–280 m. The species has also been photographed underwater off the Poor Knights Islands Reserve and Burgess Island, Mokohinau Group, in New Zealand. It is most similar to Parapercis binivirgata (Waite, 1904) in morphology, coloration and meristic values, but is unique among the genus in having a combination of dorsal-fin rays V, 23, anal-fin rays I, 19, lateral-line scales 57–63, vomer with 1–2 irregular rows of robust conical teeth, palatines with 1–2 rows of small teeth, angle of subopercle smooth, 10 abdominal and 22 caudal vertebrae, and coloration, including seven broad reddish-brown bands on the upper body between the spinous dorsal-fin and the caudal peduncle, most bands bifurcated into close-set double bars with black smudge-like blotches below, and membrane of the spinous dorsal fin black. Comparison of the mitochondrial cytochrome c oxidase subunit 1 (CO 1) genetic marker utilised in DNA barcoding produced a genetic divergence of 5.38% and 7.63% between the new species and its two closest sampled congeners. The holotype of P. binivirgata is identified from two specimens previously regarded as syntypes, some revisions are made to meristic data in the original description of the latter, and a detailed description of the revised geographic range of P. binivirgata is provided.

Balanomorph barnacles of the superfamilies Chionelasmatoidea and Pachylasmatoidea collected by various French deep-sea expeditions in the waters of New Caledonia, Vanuatu, and the Wallis and Futuna Islands are discussed. One sample from the Marianas Islands is also included. Of the 21 species reported herein, 18 are new to science, 2 are recognised as relictual, and 1 represents a northward range extension within the waters of the southwestern Pacific Ocean. In addition 4 new genera and 1 new subfamily are described. An exceptional diversity of species occurs in the subfamilies Pachylasmadnae and Hexelasmadnae of the family Pachylasmatidae. The number of new pachylasmatines described represents 46% of the known species and that of the new hexelasmatines 40%, indicating the richness of these waters. Of the 17 new species described from the waters of New Caledonia, Vanuatu, and the Wallis and Futuna Islands, 14 are considered presently to be endemic to the Vanuatu/New Caledonian region and the remaining 3 occur in a broader area which includes the Futuna and Wallis Islands region. The richest fauna occurs at the Loyalty Islands (15 species), the Norfolk Ridge (11 species) and New Caledonia (11 species). The occurrence of 2 relictual species, the chionelasmaune Chionelasmus darwini and the eolasmatineWaite/aima boucheti, in the waters of the New Caledonian region supports the hypothesis that the southwestern Pacific is a relictual area.

Les espèces les plus communes de crustacés décapodes et stomatopodes de Nouvelle- Calédonie ont été photographiées en mars 2009 dans 3 stations principales : en Province Sud, aux environs de Nouméa et sur les îlots Rédika et Ka ; en Province Nord, entre la presqu'île de Pindaï et Voh ; et aux îles Loyauté, à Lifou. Au total 19 stations ont été visitées en pêche à pied à basse-mer ou en plongée sous-marine sur des fonds de 1-20 m, de jour et de nuit. Une petite collection de référence a été constituée pour un examen au laboratoire nécessaire à certaines déterminations. Cette récolte est déposée dans les collections du Muséum national d'Histoire naturelle de Paris. Les photographies des auteurs réalisées in situ ou au laboratoire ont été complétées avec celles d’une dizaine de plongeurs photographes ayant accepté de participer à ce projet de recherche. La photothèque ainsi constituée comprend plus de 600 clichés exploitables, correspondant à 176 espèces différentes. Ces photographies sont présentées sur des planches photographiques pour servir d’aide à la détermination aux gestionnaires de l’environnement marin de Nouvelle-Calédonie et aux plongeurs photographes amateurs. Les espèces sont présentées par ordre alphabétique sur des planches regroupées par grands groupes taxonomiques : stomatopodes et langoustes, crevettes, bernard l’ermite, et crabes. Les déterminations provisoires sont indiquées par 'cf.' Parallèlement à cet inventaire photographique, une liste documentée préliminaire des espèces de crustacés stomatopodes et décapodes terrestres et de petits fonds, en excluant les espèces toujours récoltées au-delà de 100 m, est proposée pour la Nouvelle-Calédonie et les archipels voisins (Chesterfield, Entrecasteaux, Loyauté). Cette liste a été compilée en collaboration avec B. Richer de Forges et C. Hoffschir du centre IRD de Nouméa à partir des données de la BD 'Océane', complétées par les nouveaux signalements effectués au cours de ce travail et une recherche bibliographique supplémentaire.

The anatomy of Ceratoxancus is characterized by a short or very short proboscis, the presence of an accessory sali vary gland, the ventral odontophoral retractor passing through the nerve ring, and the position of the buccal mass at the proboscis base in contracted condition. These characters are shared by other representatives of the subfamily and confirm the classification of Ceratoxancus in the Ptychatractinae, until now based on shell and radula characters. Ceratoxancus Kuroda, 1952, comprises six species of which four are described as new from the New Caledonia region in deep water (530-830 m). Ceratoxancus elongatus Sakurai, 1958, is removed from the synonymy of C. teramachii Kuroda, 1952, and both species are recorded from the south west Pacific. Species of Ceratoxancus with a long labral spine present numerous shell breakages, while toothless species have mu ch fewer scars, and it is hypothesized that the tooth and outer lip are used in prey capture with accompanying shell breakage.

Consequently all of these nominal genera are synonymised with Exilia, with a stratigraphical range from Late Cretaceous to Recent. Anatomically, Exilia is similar to other ptychatractine genera, but is characterized by a stomach with a long, narrow caecum, a penis with terminal fold surrounding the seminal papilla, and a radula with rachidian teeth with broad lateral flaps. Recent species of Exilia are restricted to deep water at middle to low latitudes in the Indian and Pacific oceans. Exilia hilgendorfi (Martens, 1897) is treated as a species highly variable within its broad IndoPacific distribution, with Benthovoluta gracilior Rehder, 1967, B. claydoni Harasewych, 1987, and B. prellei Bozzetti, 200 I considered local variants. Three new species are described: Exilia graphiduloides sp. nov. (New Caledonia, 520 m), E. vagrans sp. nov. (West and SW Pacific, 865-1280 m), and E. kiwi sp. nov. (New Zealand, 1386-1676 m).

The anatomy and evolution of the radular apparatus in predatory marine gastropods of the superfamily Conoidea is reconstructed on the basis of a molecular phylogeny, based on three mitochondrial genes (COI, 12S and 16S) for 102 species. A unique feeding mechanism involving use of individual marginal radular teeth at the proboscis tip for stabbing and poisoning of prey is here assumed to appear at the earliest stages of evolution of the group. The initial major evolutionary event in Conoidea was the divergence to two main branches. One is characterized by mostly hypodermic marginal teeth and absence of an odontophore, while the other possesses a radula with primarily duplex marginal teeth, a strong subradular membrane and retains a fully functional odontophore. The radular types that have previously been considered most ancestral, “prototypic” for the group (flat marginal teeth; multicuspid lateral teeth of Drilliidae; solid recurved teeth of Pseudomelatoma and Duplicaria), were found to be derived conditions. Solid recurved teeth appeared twice, independently, in Conoidea – in Pseudomelatomidae and Terebridae. The Terebridae, the sister group of Turridae, are characterized by very high radular variability, and the transformation of the marginal radular teeth within this single clade repeats the evolution of the radular apparatus across the entire Conoidea.

The new family Belomitridae is established for the deep-water buccinoid genus Belomitra P. Fischer, 1883, based on morphological (shell and radulae) and molecular evidence. The rachiglossate radula is uniquely characterized by a multicuspid rachidian and lateral teeth with very long narrow bases and two small cusps closer to tip. Molecular analysis of a reduced set of Buccinoidea did not resolve the group as a clade, but shows that Belomitridae forms a well supported clade within Buccinoidea. Species of Belomitra have adult sizes in the 7-53 mm range; they live in deep water, mostly in the 500-2,000 meters range, at low and mid latitudes. Eleven valid species described from the Indo-Pacific were originally named in the families Buccinidae, Columbellidae, Cancellariidae, Volutidae, and Turridae. Fourteen new species are described: Belomitra nesiotica n. sp. (Society Islands to Tonga and Fiji in 580-830 m), B. bouteti n. sp. (Society and Tuamotu Islands in 430-830 m), B. subula n. sp.

In the ancillariid genus Amalda, the shell is character rich and 96 described species are currently treated as valid. Based on shell morphology, several subspecies have been recognized within Amalda hilgendorfi, with a combined range extending at depths of 150–750 m from Japan to the South-West Pacific. A molecular analysis of 78 specimens from throughout this range shows both a weak geographical structuring and evidence of gene flow at the regional scale. We conclude that recognition of subspecies (richeri Kilburn & Bouchet, 1988, herlaari van Pel, 1989, and vezzaroi Cossignani, 2015) within A. hilgendorfi is not justified. By contrast, hilgendorfi-like specimens from the Mozambique Channel and New Caledonia are molecularly segregated, and so are here described as new, as Amalda miriky sp. nov. and A. cacao sp. nov., respectively. The New Caledonia Amalda montrouzieri complex is shown to include at least three molecularly separable species, including A. allaryi and A. alabaster sp. nov. Molecular data also confirm the validity of the New Caledonia endemics Amalda aureomarginata, A. fuscolingua, A. bellonarum, and A. coriolis. The existence of narrow range endemics suggests that the species limits of Amalda with broad distributions, extending, e.g., from Japan to Taiwan (A. hinomotoensis) or even Indonesia, the Strait of Malacca, Vietnam and the China Sea (A. mamillata) should be taken with caution.

Eight species of benthopelagic synaphobranchid eels (Synaphobranchidae, Synaphobranchus affinis, S. brevidorsalis, S. oregoni, Diastobranchus capensis, Haptenchelys texis, Meadia abyssalis, Dyssomina rugoso, and Atroctodenchelys robinsorum sp. nova) were collected during MUSORSTOM cruises in 1985- 1986 and 1994-1999 off New Calcdonia and adjacent underwater rises. Descriptions are given for the two monotypic genera Haptenchelys and Atractodenchelys, previously known only from the North Atlantic and thus recorded for the first time in the Pacific, and two new species, M. abyssallis and D. rugosa, for the first time recorded in the south western Pacific. A description of the new species, A. robinsorum sp. nova, is provided based on three specimens collected in the mesobenthic zone off Chesterfield and Vanuatu Islands. The new species is distinct from its Atlantic counterpart A. phrix by the greater number of vertebrae ( 186-199 vs. 16X-172), greater number of vomcrine tceth (7-8 vs. 5), greater number of pores in supraorbital and infraorbital canals, and lower number of pores in prcopcrcular-mandibular canal.

The results are presented of a study of the collection of congrid (18 species) and nettastomatid (4 species) eels collected by the MUSORSTOM and other expeditions on the underwater rises and island slopes in the western tropical part of the Pacific Ocean. The following new species were described: three species of the genus Ariosoma (A. sereti and A. multivertebratum from the waters of the Marquesas Islands and A. sazonovi from the waters of the Philippines), two species of the genus Gnathophis ( G. neocaledoniensis from New Caledonia and G. asanoi from the Philippines), and one species each from the genera Parabathymyrus (P fijiensis from the Fiji Islands), Congriscus (C. marquesaensis from the Marquesas Islands), Acromycter (A. longipectoralis from the waters of New Caledonia), Blachea (B. longicaudalis from Fiji and New Caledonia), and Saurenchelys (S. taiwanensis from the waters of Taiwan). The validity of Ariosoma howensis (McCulloch & Waite), Gnathophis heterognathos (Bleeker), and Macrocephenchelys brevirostris (Chen & Weng) is confirmed. For the first time, C. maldivensis, P adenensis, and D. polystigmatus, known earlier only by occurrences in the Indian Ocean, were recorded in the western part of the Pacific Ocean.

Bathycongrus trimaculatus is described from 16 specimens collected from moderately deep water off the Solomon Islands, Fiji, and New Caledonia in the southwestern Pacific. It is distinguished from all other species by the presence of three conspicuous dark spots in the dorsal and anal fins; by having the vomerine teeth in an elongate patch with all the teeth about the same size and none of them greatly enlarged; by having fewer vertebrae; and by its small size. Bathycongrus bleekeri is redescribed, based on the unique holotype and two additional specimens, and compared to other species of the genus.

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.

A new cratigonid genus and species, Pseudopontophilus serratus n. gen., n. sp., is established from the southwestern Pacific. The new genus is closely related to Pontophilus Leach, 18 17 and Parapontophilus Christoffersen, 1988 in having at least one pair of lateral teeth oil the rostrum and a postorbital suture on the carapace. It is distinguished from both Pontophilus and Parapontophilus in the completely loss of exopod on the First pereopod and the less reduced second pereopod. Considerable variation in the number of median spines oil the carapace, which not appear to be correlated with either size or sex, is found in this new species.

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.

The crangonid genus Lissosabinea Christoffersen, 1988 was established to accommodate two rare deep-water species: Sabinea indica De Man, 1918 and S. tridentata Pequegnat, 1970 (type species). A study of collections made by French expeditions to the western Pacific, supplemented by material from other sources (including types of both known species), has led to a review of the genus. This Study shows that the hypothesis placing Lissosabinea as a sister group of a clade containing three genera: Vercoia, Prionocrangon and Paracrangon, was derived from an insufficient character analysis. Lissosabinea appears most closely related to Sabinea, as suggested by the original generic assignment of the two known species. Lissosabinea maintains full generic status, as the species referred to the genus are clearly differentiated from the three species assigned to Sabinea by a number of morphological characters. Three new species of Lissosabinea are described: L. armata n. sp. from New Caledonia; L. ecarina n. sp. from the Philippines and Indonesia, and L. unispinosa n. sp. from New Caledonia and Tonga. The two known species are redescribed, and L. indica is newly recorded from New Caledonia. The bathymetric and geographic ranges of the species are briefly discussed. A key to the identification of the species of the genus is presented.

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.
