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.

P. boucheti is closely related to other Perotrochus species from the Indo-West Pacific such as P. africanus Tomlin, 1948, P. teramachii Kuroda, 1955, P. tangaroana Bouchet & Métivier, 1982 and P. westralis (Whitehead, 1987). Consistent differences in colour of teleoconch and base, sculptural pattern of basal disc and selenizone, shape of aperture and proportion of surface area covered by the umbilical region callus pad on basal disc allow separation on specific level. This represents the fourth species of living Perotrochus in the South Pacific.

During the past decade, a large number of multi-gene analyses aimed at resolving the phylogeneticrelationships within Decapoda. However relationships among families, and even among sub-families, remain poorly defined. Most analyses used an incomplete and opportunistic sampling of species, but also an incomplete and opportunistic gene selection among those available for Decapoda. Here we test in the Caridea if improving the taxonomic coverage following the hierarchical scheme of the classification, as it is currently accepted, provides a better phylogenetic resolution for the inter-families relationships. The rich collections of the Muse´um National d’Histoire Naturelle de Paris are used for sampling as far as possible at least two species of two different genera for each family or subfamily. All potential markers are tested over this sampling. For some coding genes the amplification success varies greatly among taxa and the phylogenetic signal is highly saturated. This result probably explains the taxon-heterogeneity among previously published studies. The analysis is thus restricted to the genes homogeneously amplified over the whole sampling. Thanks to the taxonomic sampling scheme the monophyly of most families is confirmed. However the genes commonly used in Decapoda appear non-adapted for clarifying inter-families relationships, which remain poorly resolved. Genome-wide analyses, like transcriptome-based exon capture facilitated by the new generation sequencing methods might provide a sounder approach to resolve deep and rapid radiations like the Caridea.

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.

The exploratory fishing survey ZoNéCo 6 was canied out on board the R.Y. Alis of the IRD (Institut de Recherche pour le Développement) from 1-14 Décember 1998. lts main objective was to show whether commercial fish resources are present at depths between 300 and 800 m on the outer reef slopes of the Fairway-Lansdowne Bank and the Chesterfield Atoll. Two fishing techniques were used, bottom trawling and bottom longlining. The choice of fishing spots was based on both acoustic surveys using a 28 kHz FURUNO FCY 292 and the bathymetric charts produced during the seabed mapping survey ZoNéCo 4 canied out by the R.Y. L'Atalante. The duration of the trip was splitted into 41, l % devoted to transit, 27 % to bathymetry, 22.3 % to fishing and 9,6 % to waste of time due to bad weather conditions. 17 fishing stations were completed of which 9 were trawl hauls and 8 bottom longline sets amounting to a fishing effort close to 5000 hooks. Three trawl stations and 3 longline sets were made on the slopes of the Chesterfield Atoll whilst 6 trawl stations and 5 longline sets were completed on the slopes of the Fairway-Lansdowne Bank. The total catch was 822 kg of which 243 kg were caught with the trawl and 579 kg with the longline. The trawl did not catch any commercial species, shark amounting to 42 % of the catch, bone fishes 40 %, Crustaceans 9 % and Cephalopods 9 %. The average trawl catch rate was 0,6 tonne/km2 (6,06 kg/ha). The only commercial species caught with the longline were « red snappers» Etelis . carbunculus and E coruscans amounting to 211 kg (36,4 % of the total weight) with a catch rate of 4,3 kg/100 hooks. Sharks dominated the catch both in terms of number and weight (320 kg amounting to 55,3 % of the catch). Gnly one Beryx splendens was caught. With the exception of « red snappers », the survey did not show the presence of commercial target resources within the 300-800 m depth range of the prospected area.

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.

Seventy specimens of pycnogonid from New Caledonia and the Solomon Islands, collected during cruises from the Paris Museum, are described. No pycnogonids have been recorded previously from the Solomon Islands. Of the sixteen species identified, three ammotheids, Bathyzetes umbrella, Cilunculus cymobostrychos and C. mergus, are new to science. The distinctions of the sibling species Colossendeis pipetta Stock, 1991 and C. sinuosa Stock, 1997 are analyzed morphometrically. The pycnogonid fauna of the Melanesia-Micronesia-Polynesia region is summarized.

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.

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.

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.

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

Seamounts were often considered as‘hotspots of diversity’ and ‘centers of endemism’,but recently this opinion has been challenged. After 25 years of exploration and the work of numerous taxonomists, the Norfolk Ridge (Southwest Pacific) is probably one of the best-studied seamount chains worldwide. However,even in this intensively explored area, the richness and the geographic patterns of diversity are still poorly characterized. Among the benthic organisms,the post-mortem remains of mollusks can supplement live records to comprehensively document geographical distrbutions. Moreover, the accretionary growth of mollusk shells informs us about the lifes pan of the pelagic larva.To compare diversity and level of endemism between the Norfolk Ridge seamounts and the continental slopes of New Caledonia we used species occurrence data drawn from (i) the taxonomic literature on mollusks and (ii) a raw dataset of mainly undescribed deep-sea species of the hyperdiverse Turridae. Patterns of endemism and species richness were analyzed through quantitative indices of endemism and species richness estimates or metrics.To date, 403 gastropods and bivalves species have been recorded on the Norfolk Ridge seamounts. Of these, at least 38 species(10%) are potentially endemic to the seamounts and nearly all of 38 species have protoconchs indicating lecithotrophic larval development. Overall, our results suggest that estimates of species richness and endemism ,when sampling effort is taken into account, were not significantly different between slopes and seamounts. By including in our analyses 347 undescribed morphospecies from the Norfolk Ridge, our results also demonstratet he influence of taxonomic bias on our estimates of species richness and endemism.

An examination of extensive collections made in New Caledonia and nearby islands by the ORSTOM Center in Nouméa, New Caledonia, of collections kept at various museums, and collections of live material made by the author in New Caledonia and in Queensland, Australia, has revealed that a total of 20 species belonging to five genera of trapeziid crabs inhabit the Coral Sea region. Two of the species belonging to the genus Trapezia are described as new. The taxonomic status of several species, particularly Trapezia cymhce (Herbst, 1801), is also revised.

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.

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.

During the French-Indonesian expedition KARUBAR off Kai and Tanimbar Islands (Moluccas) in 1991, eight species of Stylodactylidae were collected. One of these species, Parastylodactylus moluccensis was new. Two other species, Parastylodactylus richeri Cleva, 1990, and Neostylodactylus affinis Hayashi & Miyake, 1968, are recorded from the region for the first time and the remaining five species, Stylodactylus tokarensis Zarenkov, 1968, S. multidentatus Kubo, 1942, S. libratus Chace, 1983, Parastylodactylus bimaxillaris (Bate, 1888), and Stylodactylus licinus Chace, 1983, are already known from the Indonesian area, the last one having been recorded recently by TAKEDA and HANAMURA (1994). On the other hand, some specimens, at first identified doubtfully as Stylodactylus libratus, and related to Stylodactylus pubescens Burukovsky, 1990, have been causing trouble to us, and we have not find till now a satisfying solution: they are mentionned here as Stylodactylus sp. Stylodactylus brevidactylus Cleva, 1990, considering the variability observed through 49 specimens of S. multidentatus Kubo collected during this cruise, is synonymised with this species. We added to the indonesian material, for each different species, the specimens collected recently from Wallis and Futuna, the Vanuatu and New-Caledonia. The species from these three countries which have not been collected during the KARUBAR expedition are mentionned at the end of this study.

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.

A new species belonging to the genus Spkaerodromia, S. lamellata, is described. It was caught by trawling off the SE of New Caledonia at a depth of 400 m. This species can be recognized, at first glance, from the four other species of the genus by the lamellated anterolateral margins of the carapace.

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

Hymenopenaeus obliquirostris ( Bate, 1881), a relatively poorly known species, is redescribed, figured and compared with H. halli Bruce, 1966. Two other species of Hymenopenaeus, H. methalli from the southwest Pacific and H. fallax from Hawaii, are described as new. All these species are closely related to one another. They are distinguished essentially by the presence or absence of a postrostral carina, the presence or absence of a fixed spine on the merus of the first pereopods, and the shape of parts of the thelycum and petasma.

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.

Five new amino acid derivatives were isolated from the New Caledonian sponge Jaspis carteri, together with known bengamides A and B. The structures of the new compounds were determined by interpretation of their spectral data and by comparison with spectral data of known bengamides. Compounds 4-7 are simply the tridecanoate and pentadecanoate analogues of the original bengamides A and B, whereas compound 8 is a caprolactam formamide derivative of bengamide B.

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.

Material from recent expeditions off Vanuatu and Wallis and Futuna islands (NE of Fiji) include new records of deep water Pectinoidea. The 20 species recorded from Vanuatu are shared with New Caledonia (80%), Indonesia (70%) and Wallis and Futuna (60%), and the 24 species recorded from Wallis and Futuna are shared with New Caledonia (75%), Indonesia (63%) and Vanuatu (54%). Parvamussium musorstomi sp. novo is described from Wallis and Futuna. The New Caledonia records of Propeamussium maorium are revised and reidentified as P. investigatoris. Parvamussium cristatellum and Propeamussium siratama are recorded and P. richeri sp. novo is described from New Caledonia. A lectotype is designated for Propeamussiwn jefjreysii.

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.

The Macroramphosid fish Notopogon xenosoma Regan 1914 is recorded on the northern part of the Norfolk ridge and the southern shelf of New Caledonia from ORSTOM trawl surveys. It becomes the most northernly distribuuon m the south-west Pacific Ocean for this subtropical species. Other specimens have been identified from Madagascar collections and induces the same conclusion for the south-west Indian Ocean.

From the Philippines, Vanuatu, and New Caledonia, ten new species of Rissoinidae are described, namely Ailinzebina laticostata, A. sleursi, Rissoina aspera, R. guttulata, R. limicola, R. maestratii, R. neptis, R. opalia, R. quasimodo, and Takirissoina crocata. The material was obtained by various cruises organized by, or in cooperation with, the Muséum National d’Histoire Naturelle in Paris. The new species are compared with other rissoinids that are already known. Their vertical distribution varies from 2 to 430 m below sea-level.

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.

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.

The tropical deep-water Cominellinae commonly assigned to the genera Manaria E. A. Smith, 1906 and Eosipho Thiele, 1929 are revised. While the taxonomic details at the generic level were discussed by Kantor et al. (2013), the species level is discussed here. Twentyone new species are described: Manaria astrolabis n. sp. (French Polynesia), M. borbonica n. sp. (Réunion), M. circumsonaxa n. sp. (Papua New Guinea and the Solomons), M. corindoni n. sp. (Indonesia), M. corporosis n. sp. (the Solomons, Vanuatu, Coral Sea and New Caledonia), M. explicibilis n. sp. (Papua New Guinea and the Solomons), M. excalibur n. sp. (Indonesia and Western Australia), M. fluentisona n. sp. (the Solomons, Fiji, Wallis and Tonga), M. hadorni n. sp. (Papua New Guinea and New Caledonia), M. indomaris n. sp. (India), M. loculosa n. sp. (Fiji), M. lozoueti n. sp. (North Fiji Basin), M. terryni n. sp. (Mozambique Channel), M. tongaensis n. sp. (Tonga), M. tyrotarichoides n. sp. (Mozambique Channel), Calagrassor bacciballus n. sp. (Philippines), C. delicatus n. sp. (New Zealand), C. hespericus n. sp. (Mozambique), C. pidginoides n. sp. (Philippines, Papua New Guinea, the Solomons and Vanuatu), Enigmaticolus marshalli n. sp. (Kermadec Ridge, Monowai Caldera), and E. voluptarius n. sp. (New Caledonia). Considerable range extensions are recorded: Manaria kuroharai Azuma, 1960 is recorded from the Solomons, New Caledonia, Vanuatu and Tonga; M. brevicaudata (Schepman, 1911) is recorded from Taiwan, the Philippines, the Solomons and Fiji; and Calagrassor poppei (Fraussen, 2001) is recorded from Indonesia and the Solomons. Lathyrus jonkeri Koperberg, 1931, a fossil described from Indonesia, is recorded from the Recent fauna of Indonesia, Philippines and Fiji and is redescribed and placed in Manaria. Sipho jonkeri Koperberg, 1931, another fossil described from Indonesia in the same work, is a secondary homonym of Manaria jonkeri (Koperberg, 1931) and is renamed Manaria koperbergae nom. nov.

The greatest geographic source of new taxa is the islands and underwater features off northern New Zealand. The new shell-morphological term "sutsel" is introduced for the area between the SUTure and the SELenizone.

Descriptions of three new species of the aulopid genus Hime from the central and western Pacific and presumably the easternmost Indian Ocean are presented. Hime surrubea sp. nov., confined to the Hawaiian Island region, has been misidentified in species accounts and faunal lists as H. japonica and although resembling it is separable from that species by its shorter caudal peduncle, slightly larger head, larger eye, especially relative to head size, and slightly smaller pectoral and pelvic fins. Hime capitonis sp. nov. is known conclusively only from seamounts off the southern tip of New Caledonia and Vanuatu, and is distinguishable by its distinctively large head (32.3–35.6% SL) and eyes (orbital diameter 10.8–13.0% SL) and relatively few scales between the anus and anal fin origin (7–9). The Indonesian H. caudizoma sp. nov. is so far known from only 8 specimens, acquired in markets in southeastern Lombok and presumably caught nearby in what would be regarded the eastern reaches of the Indian Ocean. The species is recognisable by its dorsal fin of rather uniform moderate height with nearly straight distal margin and 17 rather than 16 rays, none of which is filamentous in either sex, the second penultimate ray rather than anterior rays the longest in males. Like the other two described here, H. caudizoma has among the largest head and eyes of the family. Observations on the dorsal fin form and other features of H. microps Parin & Kotlyar, 1989 are provided based on a large male specimen collected at Rapa Iti, Austral Islands and a re-evaluation of the original description.

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.

The homolid spermatozoon, as exemplified by Homola sp., Paromola sp. and Paromola petterdi, differs markedly from spermatozoa of crabs of the Heterotremata-Thoracotremata assemblage but agrees with the sperm of dromiids, in the strongly anteroposteriorly depressed acrosome (apomorphy?) and the capitate form of the perforatorium (a major synapomorphy seen nowhere else in the Crustacea). These similarities support inclusion of the Dromiidae and Homolidae in a single grouping, the Podotremata. The homolid perforatorium differs from that of dromiids in the autapomorphic spiked-wheel form of the anterior expansion. Homolid spermatozoa show nuclear arms symplesiomorphic of all investigated crabs (small or questionably sometimes absent in Dromiidae), and corresponding loss of purely microtubylar arms seen in other reptants. Homolid sperm agree with those of dromiids (synapomorphy?), raninids, higher heterotremes and thoracotremes (homoplasies?) but differ from lower heterotremes, in lacking microtubules in the nuclear arms. A posterior median process of the nucleus in homolids, not seen in dromiids, is shared with anomurans and lower heterotremes. No featlires in the ultrastructure of homolid or dromiid sperm have been detected which associate them exclusively with either the Raninidae or the heterotreme and thoracotreme Brachyura.

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.

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.

Species of the anglerfish genus Chaunax Lowe, 1846 from the New Zealand region are taxonomically reviewed with six species recognized and described: Chaunax penicillatus McCulloch; C. nudiventer Ho & Shao, a new record for New Zealand; and four species new to science. Chaunax flavomaculatus sp. nov. distinguished by having its skin covered with a mix of numerous bifurcated and simple spinules, large yellow spots on dorsal surface of fresh specimens, and brownish coloured escal cirri; Chaunax mulleus sp. nov. by having a uniformly pink body with a deep red colour on ventral surfaces of the outer pectoral-fin and pelvic-fin, and lower part of caudal fin; Chaunax reticulatus sp. nov. by having cirri on the dorsal surface of head, and a pale reticulate colour pattern on a greyish background dorsally; and Chaunax russatus sp. nov. by its very wide illicial trough that is usually as wide or wider than the diameter of the pupil, and uniformly deep red body colour with creamy white to fuzzy greyish spots or patches on its dorsal surface. A key to species recognized from the study area is given.

Examination and taxonomic review of the batfishes collected from New Zealand and adjacent waters reveals five nominal species: Halieutopsis bathyoreos and Malthopsis mitrigera are recorded from New Zealand for the first time; the synonymy of Halieutaea maoria with H. stellata is confirmed, and two new species are described. Malthopsis asparata sp. nov. is unique in having stout principal bucklers with prominent spines. Malthopsis parva sp. nov. differs from congeners in having a naked abdomen, a short rostral spine directed upward, and all principal bucklers blunt.

A revision is provided of the Indo-Pacific species of the subfamily Scyllarinae. All of these species were formerly placed in the genus Scyllarus Fabricius, 1775, but a closer study revealed that several genera could be distinguished within the subfamily. The 13 new genera now recognized in the Indo-Pacific biogeographic region are as follows: Acantharctus n. gen., Antarctus n. gen., Antipodarctus n. gen., Bathyarctus n. gen., Biarctus n. gen., Chelarctus n. gen., Crenarctus n. gen., Eduarctus n. gen., Galearctus n. gen., Gibbularctus n. gen., Petrarctus n. gen., Remiarctus n. gen. and Scammarctus n. gen. Diagnoses and keys are provided for all the genera and their species. New and insufficiently known species have been described extensively, for the others additional morphological details are given. New species are: Bathyarctus chani n. gen., n. sp., B. steatopygus n. gen., n. sp., Petrarctus veliger n. gen., n. sp., Chelarctus crosnieri n. gen., n. sp., Eduarctus pyrrhonotus n. gen., n. sp., E. marginatus n. gen., n. sp., E. perspicillatus n. gen., n. sp. and E. reticulatus n. gen., n. sp. Furthermore efforts were made to provide each species with a complete synonymy, a description of the colour, its biology, habitat and geographical distribution. All the material examined is listed in detail. Where appropriate, remarks are provided on nomenclature, published data on the larval development and other topics.

Maculotriton ingens Houart, 1987 is transfen'ed from Ergalataxinae to Ingensia gen. novo in Muricinae. Phyllocoma Tapparone Canefri, 1881 is tentatively assigned to Muricinae, and Pagodula Monterosato, 1884, a hitherto Mediterranean and eastern Atlantic monotypic genus, is here used to include several Indo-West Pacific, eastern, and western Atlantic species formerly assigned to Trophonopsis Bucquoy & Dautzenberg, 1882 or to Trophon S. l. Additional records of previously described and I or recorded species of Pterynotus Swainson, 1833, Actinotrophon Dall, 1902, Leptotrophon Houart, 1995, and Pagodula Monterosato, 1884 from the New Caledonia region are noted. Eleven new species are described. Five are representatives of Muricinae: Pterynotus (Pterynotus) rubidus sp. nov., Dermomurex (Trialatella) triclotae sp. nov., and Ingensia brithys gen. novo and sp. nov., from New Caledonia, Phyllocoma platyca sp. novo from off Wallis Island, and Poirieria (Actinotrophon) tenuis sp. novo from Vanuatu and off Wallis; one is a muricopsine: Muricopsis (Murexsul) micra sp. novo from New Caledonia; four are trophonine: Leptotrophon alis sp. nov., L. chlidanos sp. nov., L. perclarus sp. nov., and Pagodula procera sp. nov., from New Caledonia; one is a rapanine: Thais (Mancinella) grossa sp. nov., from New Caledonia and Vanuatu.

Two new species of Timbellus are described from the Coral Sea and the New Caledonia region with extension to Fiji, Tonga and the Kermadec Islands for one species. Both species are compared to T. richeri (Houart, 1987) and T. vespertilio (Kuroda, 1959). Nine species of the genus Timbellus are recorded from the Coral Sea and the New Caledonia region. Ouly one, T. bilobatus n. sp. Is known from other localities in the Indo-West Pacific province.

The recent genetic analysis of the muricid subfamily Ergalataxinae has led to a better understanding of this subfamily, but some species were left without appropriate generic assignments and the classification of others required revision. This knowledge gap is partially filled herein, with new combinations and the description of three new genera. The examination of new material, along with a careful re-examination of and comparison to existing material, resulted also in the identification of nine new species. These new genera and new species are described herein, lectotypes are designated and new combinations are given. The geographical range of all the new species is provided on maps. All new species are compared with related or similar species. The radula of Morula palmeri Powell, 1967 is illustrated for the first time.

The classification of the subfamily Typhinae is revised based on a molecular phylogenetic analysis. The genera Typhina Jousseaume, 1880, Typhisopsis Jousseaume, 1880 and Typhisala Jousseaume, 1881 are here treated as synonyms, and Typhina is given precedence over Typhisopsis. Trubatsa Dall, 1889 is confirmed as a separate, valid genus, based on morphological shell characters and molecular analysis. Choreotyphis Iredale, 1936 is also regarded as a valid genus but still requires validation by molecular analysis. An appendix of Recent Typhinae includes a short description of each genus. The list of Typhinae recorded from New Caledonia is updated. The validity of Trubatsa lozoueti (Houart, 1991), a species so far known only from the empty collected holotype, is confirmed by the morphological and molecular analysis of a second specimen.

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.

Features of the spermatozoon of Calocarcinus apicanus which are general for heterotremes and endorse its inclusion in the Heterotremata are: extension of the subacrosomal chamber almost to the anterior apex of the sperm, presence of an acrosome ray zone, and presence of a thickened ring where the capsule surrounds the base of the subacrosomal chamber. A feature shared with ,highern heterotremes is the restriction of cytoplasm to the periacrosomal region, the arms being nuclear only, in contrast with invasion of their chromatin with cytoplasm and microtubules in majids; and loss of a posterior median process, containing chromatin, which is present in majids as in raninids and homolids. The relationship of Calocarcinus with xanthids is unequivocally apported b y (1) presence of a posterior circumperforatorialz one, the xanthid ring; (2) the precise form of the acrosome ray mne which is wide anteriorly and sends a long acrosome zone; (4) division of the operculum complex into a distinct upper zone and a lower, subopercular zone of lesser diameter; and (5)presence of an accessory ring around the in Calocarcinus may indicate origin of thoracotremes from a related xanthoid stock. A difference of Calocarcinus sperm from those of xanthids is the (plesiomorphic) presence of centrioles, also seen in some heterotremes and thoracotremes. No synapomorphies which are not common to other heterotremes are shared between Calocarcinus and trapeziid sperm. nTrapeziid sperm (plesiomorphically?) lack the xanthid ring, the posterior extension of the acrosome ray zone and the irregular margin of the outer acrosome mne of Calocarcinus and xanthids. Apomorphic features of the Calocarcinus africanus sperm include a spiral Configurationn of the contents of the outer acrosome zone (autapomorphy?), as seen in cross-section, and presence of a periopercular rim. A well developed periopercular rim is known elsewhere only in Potamonautes (family Potamidae), but a rudiment occurs in some xanthids (e.g., Etisus). The periopercular rim is probably a true synapomorphy indicative of relationship of potamids to xanthoids (represented by Calocarcinus) which has been postulated elsewhere on morphological grounds.

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.

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.

The genus Belloliva (Gastropoda: Olividae) consists of small (<15 mm) operculate species and was hitherto thought to be essentially confined to coastal waters of southern and eastern Australia. We report a small radiation from deep water (100-1000 m) in the Coral Sea and New Caledonia, consisting essentially of undescribed species. The new genus Calyptoliva, which differs from Belloliva by the absence of a mantle filament and the presence of a mantle lobe, is also represented in the same area by new species. Based on correlation with shell characters, we suggest that the olivid mantle lobe is responsible for secreting the primary spire callus that overlies the suture, rather than producing the columellar callus as was previously believed (Marcus and Marcus 1959). Belloliva and Calyptoliva combine a suite of shell, radular, and anatomical characters that is shared with either the Olivinae or the Ancillariinae. This raises the question of the distinctiveness of the two classically recognized subfamilies within the family Olividae. All species have paucispiral protoconchs with inferred limited larval dispersal, and many have extremely narrow distributions, sometimes endemic to a single guyot, or they show discrete geographical differentiation. New species: Belloliva iota sp. nov., Belloliva alaos sp. nov., Belloliva apoma sp. nov., Belloliva ellenae sp. nov., Belloliva obeon sp. nov., Belloliva dorcas sp. nov., Calyptoliva bolis gen. nov., sp. nov., Calyptoliva amblys sp. nov., Calyptoliva tatyanae sp. nov.

The genus Pseudolatirus Bellardi, 1884, with the Miocene type species Fusus bilineatus Hörnes, 1853, has been used for 13 Miocene to Early Pleistocene fossil species and eight Recent species and has traditionally been placed in the fasciolariid subfamily Peristerniinae Tryon, 1880. Although the fossil species are apparently peristerniines, the Recent species were in their majority suspected to be most closely related to Granulifusus Kuroda & Habe, 1954 in the subfamily Fusininae Wrigley, 1927. Their close affinity was confirmed by the molecular phylogenetic analysis of Couto et al. (2016). In the molecular phylogenetic section we present a more detailed analysis of the relationships of 10 Recent Pseudolatirus-like species, erect two new fusinine genera, Okutanius gen. nov. (type species Fusolatirus kuroseanus Okutani, 1975) and Vermeijius gen. nov. (type species Pseudolatirus pallidus Kuroda & Habe, 1961). Five species are described as new for science, three of them are based on sequenced specimens (Granulifusus annae sp. nov., G. norfolkensis sp. nov., Okutanius ellenae gen. et sp. nov.) and two (G. tatianae sp. nov., G. guidoi sp. nov.) are attributed to Granulifusus on the basis of conchological similarities to sequenced species. New data on radular morphology is presented for examined 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.

A review of the species of the Glyphocrangon caeca Wood-Mason & Alcock, 1891 group is presented based on samples obtained during French expeditions to the southwestern Pacific and western Indian Ocean, and supplemented with materials deposited in various museums and institutions in the world. Eight species are now recognized in this species group. The two previously described species, G. caeca from the Bay of Bengal and G. cerea Alcock & Anderson, 1894 from the Laccadive Sea, are rediagnosed based on literature, as types or supplemental topotypic specimens of these two species have not been available for study. Six new species are described: G. brevis n. sp. from Madagascar, G. demani n. sp. from Indonesia, G. humilis n. sp. from Japan and Taiwan, G. musorstomia n. sp. from Wallis and Futuna Islands, Vanuatu, Fiji and Chesterfield Islands, G. parviocullus n. sp. from New Caledonia, and G. rudis n. sp. from the Solomon Islands. Species of this group occur exclusively in the Indo-West Pacific. The horizontal and bathymetric distributions of the species are briefly summarized. The available data suggests that species of the group are highly localized.

Contrary to data in the literature, Nassarrius alomea Kay, 1979, has a much wider distribution than only the Hawaiian Islands. It occurs also in parts of the southwestern Pacific. Nassarius alamen and N. crebricostatus (Schepman, 1911) are shown to be separate species.

Thirty-two species of Spondylus (Spondylidae) including eight previously undescribed, are recorded from material collected off New Caledonia and adjacent waters. Most of the species live in shallow water in coral reef and lagoonal environments, but at least four species have their main distribution at depths around 200 m, with one species occurring at 700 m. Spondylus exiguus sp. novo is the smallest known species in the family, with a maximum size of 6.4 mm. Spondylus flabellum Reeve, 1856 is placed into the synonymy of S. anacanthus Mawe, 1823. Confusion surrounding usage of the names Spondylus anacanthus and S. sanguineus Dunker, 1852 is finally resolved. The name Spondylus anacanthus, which has previously been applied to S. occidens Sowerby, 1903, is shown to be a prior and validly proposed name for S. sanguineus. Despite being well figured by MAWE, the absence of any documented type material for Spondylus anacanthus necessitates the establishment of a neotype for this species. Lectotypes are designated for Spondylus albibarbatus, S. butleri, S. castus, S. flabellum, S. ocellatus, S. pacificus, S. plurispinosus, and S. rubicundus, all of Reeve, 1856. By First Reviser action, the name Spondylus nicobaricus Schreibers, 1793 is given precedence over S. pseudochama Schreibers, 1793.

A new species of spurdog, Squalus bucephalus sp. nov., is described from deepwater south of New Caledonia in the northern Tasman Sea. It belongs to the ‘megalops-cubensis group’ but differs from Australian forms of S. megalops in having a broader head, larger dorsal-fin spines and reaches a larger adult size. It also differs in several other meristic and morphometric details and is the only Squalus known to possess both unicuspid and multicuspid denticles in adults. It is morphologically similar to the newly described S. crassispinus from the eastern Indian Ocean, but differs in having a lower, strongly raked first dorsal fin, more vertebrae, and more slender dorsal-fin spines.

The reproductive biology of the alfonsino Beryx splendens was studied by histological examinations, gonadosomatic index and macroscopic scales of maturation of a large sample of gonads. Alfonsino is a gonochoric species. The size-frequency distribution of the sex ratio was bimodal and considered to be due to size dimorphism. In New Caledonia, the breeding period of this species occurs during the southern summer, with a peak in December to January. The spawning stage is attained at a minimum fork length of 28 cm for females and 33 cm for males. The size at which 50% of the population attain sexual maturity (FL50) is 33.2 cm for females and 34.5 cm for males. Maximum potential fecundity is estimated to lie between 270 000 to 675 000 eggs for ®sh between 34 and 40 cm in fork length. It was possible to differentiate vegetative zones, in which juvenile alfonsino grow until they reach maturity, from reproductive zones (®shing grounds) which are inhabited by mature individuals. The larvae and juveniles could be carried from the reproductive zone to the vegetative zone by currents in an oceanic eddy system.

Species of the parapagurid genus Strobopagurus Lemaitre, 1989 are reviewed based primarily on abundant specimens obtained during French campaigns across the Indo-Pacific region. A new species, S. breviacus, is described. The genus contains two other species, S. gracilipes (A. Milne-Edwards, 1891), the type of the genus, and S. sibogae (de Saint Laurent, 1972). One taxon, Parapagurus kilburni Kensley, 1973, originally described from off eastern Africa, has been found to be a junior synonym of S. sibogae. An updated diagnosis of the genus, and diagnoses and comparative illustrations of all three species, are presented together with a key to aid in their identification. Information on live coloration is provided for S. gracilipes and S. sibogae; live coloration of S. breviacus is not known.

A review of species of the genus Sympagurus Smith, 1883 (sensu Lemaitre) from the world oceans is presented. The study is based on the rich collections obtained during French campaigns in the Pacific and Indian Oceans, and on additional material in various museums and research institutions throughout the world. The 17 species recognised in this genus occur most frequently between 500 and 1000 m depth, and range from 80 to 2537 m. Some live in striking symbiosis with anthozoan or zoanthid coelenterates that can produce pseudo-shells. Three new species, S. aurantium, S. chani and S. symmetricus, are fully described and illustrated here. Sympagurus rectichela (Zarenkov 1990), a taxon originally described in Parapagurus Smith, 1879, has been found to be a junior synonym of S. dofleini (Balss, 1912); and S. papposus Lemaitre, 1996 is a junior synonym of S. burkenroadi Thompson, 1943. All previously known Sympagurus species are diagnosed or redescribed and illustrated, and data on habitat, symbiotic associations, and coloration are provided. A key to aid in the identification of all Sympagurus species is presented, and their bathymetric and geographic distributions are summarised. The geographic distribution of 14 species (82.3%) includes the Pacific Ocean, 9 (52.9.%) the Indian Ocean, and 3 (1.8%) the Atlantic Ocean. New Caledonia and adjacent islands have the highest number of Sympagurus species in the world, with 12 species known to occur there.

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

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

Based on the material deposited in the Museum national d'Histoire naturelle, Paris, collected from the Indo-West Pacific, principally from the New Caledonian region, the present paper reports 117 palaemonoid shrimp species, which belong, respectively, to Anchistioididae ( one genus, one species), Gnathophyllidae ( one genus, one species), Palaemonidae Palaemoninae ( seven genera, nine species), and Palaemonidae Pontoniinae ( 30 genera, 106 species), including eight new species. The new species are all Pontoniinae: Mesopontonia brevicarpalis sp. nov., Palaemonella komaii sp. nov., Periclimenes crosnieri sp. nov., Periclimenes forgesi sp. nov., Periclimenes loyautensis sp. nov., Periclimenes paralcocki sp. nov., Periclimenes paraleator sp. nov., and Periclimenes pseudalcocki sp. nov. The last six new species are members of the deep-water "Periclimenes alcocki species complex'', which has more than two ( usually four) pairs of dorsolateral telson spines anterior to the posterior telson margin, the cornea is usually reduced, the dactyl of the major second chela is generally flanged and the chela is sometimes covered with small tubercles. The complex is usually found at more than 200m depth in the West Pacific. The species can be distinguished from each other by the armature of ambulatory propod and dactyl, diameter of cornea, rostrum shape and the number of pairs of dorsolateral telson spines. Mesopontonia brevicarpalis sp. nov., from the southeast coast of Africa, is the seventh species of the genus. Palaemonella komaii sp. nov. is very similar to Palaemonella dolichodactylus Bruce, 1991 and Palaemonella hachijo Okuno, 1999. These three species share the features of very long and slender ambulatory pereiopods with the dactyl more than eight times longer than its basal depth and with several long setae on the dorsal dactylar margin.

This revision of the scissurellid genus Satondella Bandel, 1998 is mainly based on shell characters due to the availability of only a few live collected specimens. There are seven Recent species (two described as new) and one Eocene fossil. Satondella minuta Bandel, 1998, the type species from Indonesia, is redescribed and its range extended to New Caledonia, Solomon and Fiji Islands. Satondella tabulata (Watson, 1886) is only known from type material off Culebra Island (Puerto Rico); lectotype and paralectotypes are here designated, and similar material from the Indo-Pacific is discussed. Satondella brasiliensis (Mattar, 1987) is another W. Atlantic species, ranging from Bermuda to Brazil. Satondella senni (Geiger, 2003) is only known from the E. Pacific (Easter Island) and Satondella danieli Segers, Swinnen & Abreu, 2009 from the NE. Atlantic Ocean (Desertas and Madeira Islands). The two new species are distributed through the E. Indian and W. Pacific oceans (S. cachoi n. sp.) and W. Pacific (S. dantarti n. sp.). The Tongan Eocene fossil S. kondoi (Ladd, 1970) is redescribed and illustrated with SEM images. Satondella brasiliensis and S. cachoi have a typical scissurellid radula, except for uniquely having one cusp on the inner edge of the third lateral. The monophyly of the genus is discussed, since species currently included in Satondella show two clearly different shell patterns but all share the unique chimney-like foramen.

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

During two cruises to Vanuatu, MUSORSTOM 8 (September-October 1994) and SANTO 2006 (September-October 2006), numerous specimens of deep-sea galatheids belonging to the genus Galathea Fabricius, 1793 were collected. The specimens were caught at stations at depths between 180 and 702 m. These collections contain five new species (G. barbellata n. sp., G. echinata n. sp., G. profunda n. sp., G. raventosae n. sp. and G. sanctae n. sp.), all of which are also found in other collections obtained by French cruises to New Caledonia. Galathea barbellata n. sp., G. echinata n. sp. and G. profunda n. sp. are closely related to G. robusta Baba, 1990, from Madagascar, G. raventosae n. sp. resembles G. consobrina De Man, 1902, from Indonesia, the Philippines, South China Sea and SW Australia, and G. sanctae n. sp. is very close to G. multilineata Balss, 1913, from Japan, East China Sea, Taiwan and the Philippines.

New material of Brisingaster robillardi de Loriol 1883, including juveniles, allows a more complete description of the species. Papulae, obscured in the holotype and previously unknown for this taxon, are present. Abactinal plate arrangements provide new autapomorphies for the genus Brisingaster. Scanning electronic microscope photographs of pedicellariae are described and compared with those of Novodinia antillensis. The range of B. robillardi is extended to New Caledonia, Western Australia and Amami-o-shima, Japan. Morphological variation is present between material from the Pacific and the Indian Ocean. Novodinia helenae Rowe, 1989 is synonymized with B. robillardi. New phylogenetic evidence also supporrs a new family, the Brisingasteridae, which tentatively includes Brisingaster and Novodinia.

A phylogenetic analysis of 11 taxa and 31 characters resulted in a single most parsimonious tree that supports monophyly of the goniasterid genera Iconaster and Glyphodiscus. Four new species, Glyphodiscus magnificus n. sp., Glyphodiscus pentagonalis n. sp., Iconaster uchelbeluuensis n. sp., and Iconaster vanuatuensis n. sp., are described and two species are synonymized. At least three species within the genus Iconaster appear to have invaded shallower water from a deeper-water ancestry. Glassy tubercles, similar to those interpreted as photoreceptors in ophiuroids and other goniasterids, are present in the shallow-water Iconaster clade. Glassy tubercles are largely absent in the deeper-water sister and outgroup taxa, suggesting their occurrence is related to photic zone or shallow-water occupation. Biogeographic patterns as presently known suggest that diversification in Iconaster and Glyphodiscus has been restricted to the central and south Pacific regions.

Recent expeditions to Rapa Nui (also known as Easter Island) and New Caledonia have revealed undescribed species from mesophotic and deeper depths. This includes three new species from Rapa Nui, Hacelia raaraa, Linckia profunda (Ophidiasteridae), Uokeaster ahi (Asterodiscididae) and two new species from New Caledonia, Astroglypha pyramidata n. gen. and Ophidiaster colossus (Ophidiasteridae). The new genus Astroglypha is described for A. pyramidata but the genus also includes the Atlantic Tamaria passiflora, which is reassigned herein. Pauliastra n. gen. is designated as a replacement for the homonym issue with Pauliella. New occurrences and synonymies are addressed for taxa related to New Caledonia, Rapa Nui and adjacent regions. A morphology based phylogenetic analysis agrees with prior work which placed Goniaster among the Asterodiscididae and posits biogeographic relationships among asterodiscidid genera. Implications for the Goniasteridae and placement of Goniaster among asterodiscidid genera are discussed. Biogeography and relationships among taxa from Rapa Nui and New Caledonia are reviewed. In situ observations from species observed from Rapa Nui are included.

The very interesting and rather specialized hermit crab genera Porcellanopagurus and Solitariopagurus are represented in collections from the MUSORSTOM cruises to New Caledonia and the Marquesas by four species of the former and three of the latter. Among the species of Porcellanopagurus, three species, P. tridentatus Whitelegge, P. filholi de Saint Laurent & McLaughlin, and P. chiltoni de Saint Laurent & McLaughlin have heretofore been reported only from Australia and New Zealand; P. haptodactylus sp. nov. is a distinctive species, new to science. Solitariopagurus triprobulus Poupin& McLaughlin is reported for the first time beyond the islands of French Polynesia, and the range of S. tuerkayi McLaughlin is extended from the Kai and Tanimbar Island of Indonesia to New Caledonia, Vanuatu and Okinawa. A new species, S. trullirostris sp. nov., is described from New Caledonia and the Marquesas. The similarities and differences of the two new genera are elucidated, and an apparently rare attribute, a terminal anus, common to some species of both is discussed.

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

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

Two new species of Hymenocephalus are described from the New Zealand region and Tasman Sea. Hymenocephalus fuscus sp. n. has 11–12 pelvic fin rays, is darkly pigmented, with enlarged bony ridges on the dorsal aspects of head, lacks a chin barbel, has few (16–19) gill rakers on inner side of first arch and is similar to other species in the H. aterrimus species group. Hymenocephalus maculicaudus sp. n. has 8 pelvic fin rays, a mid-lateral line of melanophores on body and tail that extends about a head length posterior to anal fin origin, a short (7–16 % HL) chin barbel and is similar to other species in the H. megalops species group. Hymenocephalus nascens has 12–14 pelvic fin rays, lacks a chin barbel, has a mid-lateral stripe of silvery (fresh) or brownish (preserved) pigment running along trunk and tail. Hymenogadus gracilis has a serrated (weak, near tip) first dorsal fin spine, 7–9 pelvic fin rays, long (20–30% HL) chin barbel, and one row of enlarged melanophores along lateral mid-line of the tail. Hymenocephalus nascens and Hymenogadus gracilis are recorded for the first time from the New Zealand region. A key to the known New Zealand species of Hymenocephalus and Hymenogadus is provided.

Ophiuroid assemblages were successfully predicted from current museum sample data using presence-only modeling techniques and a multivariate classification on the resulting species occurrence probabilities across the Coral and Tasman Seas (20-37°S, 148-172°E). The classification involves two-stages. The first uses a non-hierarchical clustering technique to reduce the number of data points (map-pixels) to a manageable number that can be analysed in a second stage with a hierarchical classification method. For both steps, the Bray-Curtis similarity statistic is used.

The large-scale spatial distribution of seafloor fauna is still poorly understood. In particular, the bathyal zone has been identified as the key depth stratum requiring further macro- ecological research [ 1 ], particularly in the Southern Hemi- sphere [ 2 ]. Here we analyze a large biological data set derived from 295 research expeditions, across an equator- to-pole sector of the Indian, Pacific, and Southern oceans, to show that the bathyal ophiuroid fauna is distributed in three broad latitudinal bands and not primarily differentiated by oceanic basins as previously assumed. Adjacent faunas form transitional ecoclines rather than biogeographical breaks. This pattern is similar to that in shallow water despite the order-of-magnitude reduction in the variability of environmental parameters at bathyal depths. A reliable biogeography is fundamental to establishing a representative network of marine reserves across the world’s oceans [1, 3].

This is a regional revision of the Coralliophilinae (Neogastropoda: Muricidae) from the southwest Pacifi c, based on the material collected during recent expeditions to New Caledonia (including the Coral Sea, mainland New Caledonia, and the Loyalty Islands), Vanuatu, Wallis and Futuna, Fiji and Tonga. It is the fi rst revision of a tropical coralliophiline fauna based on large and extensive sampling, and it yielded a total of 97 coralliophiline species, 13 of them new: Coralliophila candidissima n. sp., C. bathus n. sp., C. norfolk n. sp., C. xenophila n. sp., C. cancellarioidea n. sp., Babelomurex natalabies n. sp., B. pallox n. sp., B. depressispiratus n. sp., B. macrocephalus n. sp., Hirtomurex marshalli n. sp., Mipus tonganus n. sp., M. alis n. sp., and M. boucheti n. sp. A lectotype is selected for Purpura monodonta Blainville, 1832. In addition, this survey resulted in new biogeographical records for 37 species from the southwest Pacifi c fauna. Regional endemicity may be as high as 17.5% (17 out of 97 species). The protoconchs of 47 species are fi gured by SEM. At least 68 species have planktotrophic development, while 10 species are probably lecithotrophic, either with a short pelagic phase or with a totally intracapsular develoment.

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

The two new species described in this paper are widely distributed in the tropical south-western Pacific; they have been found on the upper continental shelf of the area, around New Caledonia, westward to Chesterfield Islands and Lord Howe Ridge, southward to northern part of Norfolk Ridge, north- and eastward to Vanuatu, Fiji and Tonga islands. They belong to two often confused genera of subfamily Protocardiinae (sensu Keen 1980), Frigidocardium Habe, 1951 and Microcardium Th iele, 1934, that are briefly characterized herein. Frigidocardium valdentatum n. sp. is characterized by the peculiar sculpture of mid-posterior slope ending in strongly dentate margin. Frigidocardium kirana is a similar species with lower outer sculpture, more asymmetrical shape and rather strong umbonoventral fold; it is first recorded here from the tropical Southwest Pacific and Mascarene islands. Diagnostic features of Microcardium trapezoidale n. sp. include rather high trapezoidal shape and posterior sculptural area extending on 2/5 of shell length, with an anterior limit almost parallel to radial ribs in the adult and well-developed, non lamellous sculpture in the rib interstices. A comparative review of all Recent Microcardium species in the Indo-West Pacific is given, to place the new species in the context of the genus. Five Microcardium species are presently known in this area: M. gilchristi from southern Africa, M. simillimum n. comb. (for Cardium (Fragum) simillimum) from Sri Lanka and Mascarene Plateau, M. sakuraii from Japan and the Philippines (new record), M. aequiliratum from the Philippines, and M. tenuilamellosum from the Philippines and Solomon Islands (new record).

The Australasian Eucla cod, Euclichthys polynemus McCulloch, family Euclichthyidae, is described for the first time from the New Caledonian Exclusive Economic Zone where it appears to be restricted to seamount "B" (24°55'S, 168°21 'E) on the northern Norfolk Ridge southeast of New Caledonia. The Eucla cod is superficially very similar to morid cods (family Moridae), but can be distinguished by a long filamentous pelvic fin with four to six distal elements, an unequally divided anal fin, and an asymmetrical caudal fin.

Gemfishes of the genus Rexea from the New Caledonia Exclusive Economic Zone (EEZ) are reviewed based on fresh and preserved specimens. Three species are recognized: Rexea aniefurcata Parin, 1989, confirming recent records (previously also recorded as R. prometheoides), distinguished by the presence of small scales on the caudal peduncle and extending anteriorly along the edges of the lower lateral line, lateral line branching below the 4th-5th dorsal fm spines, a long pectoral fm, and dusky colour of spinous dorsal fm membrane and (in adults) pectoral fm; R. bengalensis (Alcock, 1894), first record, distinguished by its small maximum size, lateral line branching below the 5th-6th dorsal fin spines, long pectoral fin, and naked body (except lateral line); and R. alisae sp. nov., endemic, distinguished by 3-4 dorsal finlets and 4 anal finlets, lateral line branching below the 6th to 7th dorsal fin spines, posterior extent of the upper lateral line, its naked body (except lateral line), and coloration. A key to New Caledonian gemfishes {Rexea spp., Rexichthys johnpaxtoni and Promethichthys prometheus) is provided.

The genus Leiogalathea Baba, 1969 currently contains only two benthic species both occurring on the continental shelves and slope: L. laevirostris (Balss, 1913), widely reported in the Indo-Pacific region, and L. agassizii (A. Milne Edwards, 1880), from both sides of the Central Atlantic. A certain degree of morphological variability linked to their geographic distributions was previously noticed, mostly in L. laevirostris. In the present study, we revise numerous specimens collected from the Atlantic, Indian and Pacific Oceans, analysing morphological and molecular characters (COI and 16S rRNA). We found 15 new species; all of them are distinguished from L. laevirostris and L. agassizii by subtle but constant morphological differences and show clear genetic separation. Furthermore, L. imperialis (Miyake & Baba, 1967), previously synonymized with L. laevirostris, was found to be a valid species. All species are described and illustrated. Species of the genus Leiogalathea are morphologically distinguishable on the basis of the spinulation of the carapace, the shape and the armature of the rostrum, the shape of the propodi of the walking legs, and the pattern of the setae covering on rostrum, carapace and chelae. Some species are barely discernible on the basis of these characters but are highly divergent genetically.

The ecology, abundance and diversity of galatheoid squat lobsters make them an ideal group to study deep-sea diversification processes. Here, we reconstructed the evolutionary and biogeographic history of Leiogalathea, a genus of circum-tropical deep-sea squat lobsters, in order to compare patterns and processes that have affected shallow-water and deep-sea squat lobster species. We first built a multilocus phylogeny and a calibrated species tree with a relaxed clock using StarBEAST2 to reconstruct evolutionary relationships and divergence times among Leiogalathea species. We used BioGeoBEARS and a DEC model, implemented in RevBayes, to reconstruct ancestral distribution ranges and the biogeographic history of the genus. Our results showed that Leiogalathea is monophyletic and comprises four main lineages; morphological homogeneity is common within and between clades, except in one; the reconstructed ancestral range of the genus is in the Atlantic and Indian oceans (Tethys). They also revealed the divergence of the Atlantic species around 25 million years ago (Ma), intense cladogenesis 15–25 Ma and low levels of speciation over the last 5 million years (Myr). The four Leiogalathea lineages showed similar patterns of speciation: allopatric speciation followed by range expansion and subsequent stasis. Leiogalathea started diversifying during the Oligocene, likely in the Tethyan. The Atlantic lineage then split from its Indo-Pacific sister group due to vicariance driven by closure of the Tethys Seaway. The Atlantic lineage is less speciose compared with the Indo-Pacific lineages, with the Tropical Southwestern Pacific being the current centre of diversity. Leiogalathea diversification coincided with cladogenetic peaks in shallow-water genera, indicating that historical biogeographic events similarly shaped the diversification and distribution of both deep-sea and shallow-water squat lobsters.

This is the third contribution to the Indo-Pacific species of the family Conradiidae. In the present work 29 species of the genus Conradia A. Adams, 1860 and one species of the genus Conjectura Finlay, 1927 are studied, 20 of which are considered as new to science, and are described and figured. All these species are compared with the previously known species of these genera. The type material of Conradia carinifera A. Adams, 1860, Conradia cingulifera A. Adams, 1860, Conradia clathrata A.

The New Caledonian species of Cones with a main distribution below 100 m are surveyed. This fauna consists of 39 species, of which 5 are new and 18 represent significant range extensions. In addition, eight species, mostly represented by single specimens, remain unidentified. Ten species (Conus boucheti, C. kanakinus, C. luciae, C. plinthis, C. richeri, and the five new ones) are so far only known from the New Caledonia region and may be endemic. Conus smirna and C. profundorum are regarded as distinct, and two additional species are described in this species complex: C. vaubani sp. Nov., from South of New Caledonia and of the New Hebrides Arc in 440-775 m; and C. loyahiensis sp. Nov. From the Loyalty Islands in 480-575 m. Three other new species, and one subspecies, are named: Conus alisi sp. Nov. From the New Caledonia area, in 200-525 m; C. estivali sp. Nov. From the Chesterfield Islands, Coral Sea, in 355-410 m; C. gondwanensis sp. Nov. From the Norfolk Ridge, South New Caledonia, in 170-260 m; and C. orbignyi coriolisi ssp. Nov., from the Coral Sea, New Caledonia and Loyalty Islands, in 225-550 m.

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

Domiporta dianneae n. sp. Is described from the Indo-Pacific and compared to Domiporta sigillata (Azuma, 1965). Scabricola splendidula n. sp., from the Philippines and Solomon Islands is compared to Scabricola coriacea (Reeve, 1845), Neocancilla clathnis clathrus (Gmelin, 1791) and Neocancilla maciilosa (Gmelin, 1791). Mitra {Mitra) heinickei n. sp. From the Philippine Islands is compared to Mitra {Mitra) maui Kay, 1979 and Ziba? Rehderi (J. H. Webb, 1958). A new record and range for Mitra (Mitra) maui Kay, 1979 is reported. Mitra (Mitra) millepunctata Schepman, 1911 (non Mitra millepunctata Sowerby, 1889) is given a new name: Mitra (Mitra) schepmani.

Previous work that recorded 75 species of Scaphopoda in New Caledonian waters is augmented with study of new material from several expeditions. The number of species in the region is increased to 115. Of the 40 additional taxa, 28 are described as new, 7 are new records and 5 remain unidentifi ed. Material from New Caledonia previously identifi ed as Antalis phaneum (Dall, 1895) is now determined as A. albatrossae n. sp.; material previously identifi ed as Compressidentalium sedecimcostatum (Boissevain, 1906) is now determined as C. clathratum (Martens, 1881); Episiphon virgula (Hedley, 1903), formerly treated as a synonym of Dentalium subrectum Jeffreys, 1883, is revalidated; material previously identifi ed as Entalina mirifi ca (Smith, 1895) is now determined as E. dorsicostata Lamprell & Healy, 1998; Fissidentalium transversostriatum (Boissevain, 1906), previously synonymized with F. shoplandi (Jousseaume, 1894), is revalidated and the material previously reported from New Caledonia as the latter in fact belongs to the former. New synonyms: Episiphon jamiesoni Lamprell & Healy, 1998 is synonymized with Gadilina insolita (Smith, 1894); Dentalium subrectum Jeffreys, 1883 and D. bisinuatum André, 1896 are synonymized with Laevidentalium eburneum (Linné, 1767); Laevidentalium arnoldi Lamprell & Healy, 1998 is synonymized with L. houbricki Scarabino, 1995; Bathoxiphus steineri Lamprell & Healy, 1998 and B. stanisici Lamprell & Healy, 1998 are synonymized with Solenoxiphus striatulus Chistikov, 1983.

Study of deep-water chitons from around New Caledonia and Vanuatu has revealed 35 species, of which 25 species were identified to species and 10 only to genus. This article includes 7 new records for this area of which 4 are described as new species: Ischnochiton crassus Kaas, 1985, Stenosemus robustus Kaas, 1991, S. herosae n. sp., Connexochiton discernibilis Kaas, 1991, Loricella vanbellei n. sp., L. eernissei n. sp. and L. dellangeloi n. sp. In addition, Vermichiton vermiculus Kaas, 1991 is reviewed. Based on available biogeographic data it is proposed that Loricella originated off South Australia during the Oligocene, in a time of global cooling. Later, Loricella extended its range north up to Taiwan and east to Tonga, most likely remaining in the bathyal zone. These new discoveries add to the already high diversity and high proportion of endemics known from this region, and a speculative interpretation of these patterns is offered in conclusion.

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

Material collected by deep-sea expeditions in the south-west Pacific Ocean reveals a previously unrecognized radiation of the family Phyllidiidae into deeper waters, with a couple of species having a bathymetric range confined below 500 m. Whereas the shallow-water « 100 m) radiation consists mainly of species of Phyllidia, species of Phyllidiopsis make over 70% of the fauna in the 100-500 m interval, and the only two taxa recorded in the 500-750 m interval are species of Phyllidiopsis. A parallel pattern is observed in the Atlantic. There are no consistent anatomical differences between congeneric shallow and deep-water species, but taxa from deeper water are paler and have a simpler dorsal morphology. Twelve new species are described: Phyllidia orstomi sp. novo (Norfolk Ridge, 270-300 m), Phyllidiopsis brunckhorsti sp. novo (New Caledonia, 290350 m), P. anomalasp. Novo (Norfolk and Loyalty Ridges, 240-310 m), P. holothuriana sp. novo (Norfolk Ridge and Vanuatu, 110-240 m), P. macrotuberculata sp. novo (Norfolk Ridge, 270-300 m), P. futunai sp. novo (off Futuna 1., NE of Fiji, 165 245 m),P. crucifera sp. novo (off Futuna 1.,105-160 m), P. lozoueti sp. Novo (Norfolk Ridge, 235 m), P. richeri sp. novo (Norfolk Ridge, 510-750 m), P. circularis sp. novo (Norfolk Ridge, 510-530 m), P. vanuatuensis sp. novo (off Tanna 1., Vanuatu, 410 m), and P. neocaledonica sp. novo (New Caledonia, 315 m). Phyllidia varicosa var.quadrilineata Bergh, 1905, unrecorded since its description from the Flores Sea, Indonesia, is recognized as a valid species of Phyllidiopsis and recorded from Vanuatu in 160 -180 m.

There are six valid species in the traditional genus Bathydoris, all of them found in polar or deep waters: Bathydoris abyssorum Bergh, 1884 (from the deep equatorial Pacific Ocean), Bathydoris ingolfiana Bergh, 1899 (from Greenland), Bathydoris hodgsoni Eliot, 1907 (from Antarctic and subantarctic waters), Bathydoris clavigera Thiele, 1912 (from the Argentinean deep-sea basin and Antarctica), Bathydoris aioca Ev. Marcus and Er. Marcus, 1962 (from deep waters off California), and a new species, Bathydoris spiralis (from deep waters off New Caledonia). Bathydoris patagonica Kaiser, 1980 and Bathydoris violacea Baranets, 1993 are regarded as synonyms of B. hodgsoni and B. clavigera, respectively. Bathydoris spiralis is clearly distinguishable from other members of the genus mainly in having a triaulic reproductive system and a very elongated, spirally coiled deferent duct. Examination of the holotype of B. violacea revealed that it is a synonym of B. clavigera. Bathydoris vitjazi Minichev, 1969 is most likely a synonym of B. hodgsoni, but is provisionally regarded as nomen dubium until more material becomes available. The phylogenetic hypothesis supports the monophyly of the Anthobranchia but shows that the genus Bathydoris is paraphyletic. Species of Bathydoris are divided into two clades, one of them also containing the phanerobranch and cryptobranch dorids. Bathydoris type species B. abyssorum retains its name and diagnosis, but B. clavigera and B. spiralis are excluded from this genus. They are, however, provisionally maintained in "Bathydoris" s.l., a likely paraphyletic group. This result shows some incongruities between the traditional nomenclatural system and phylogenetic systematics.

One hundred and twenty-one species of deep sea “cephalaspidean” heterobranchs belonging to the genera Acteon, Crenilabium, Obrussena, Rictaxis, Japonacteon, Maxacteon, Bullina, Diaphana, Toledonia, Cylichna, Scaphander, Sabatia, Roxania, Cylichnium, Acteocina, Truncacteocina, Philine, Retusa, Pyrunculus, Volvulella, Relichna, Micratys, Gastropteron, Aglaja and Philinopsis are reported from the tropical southwest Pacifi c. Thirty-nine of these species are new: Acteon ionfasciatus, Acteon chrystomatus, Rictaxis sanguinea, Japonacteon longissimus, “Acteon” editus, “Acteon” buccinus, “Acteon” ringiculoides, “Acteon” boteroi, “Acteon” loyautensis, “Acteon” rhektos, “Acteon” profundus, “Acteon” osexiguus, “Acteon” aphyodes, “Acteon” herosae, “Acteon” comptus, “Acteon” chauliodous, “Acteon” cohibilis, Bullina rubropunctata, Toledonia neocaledonica, Toledonia epongensis, Cylichna tanyumphalos, Cylichna grovesi, Sabatia pyriformis, Roxania smithae, Cylichnium mucronatum, Cylichnium nanum, Acteocina lata, Philine habei, Philine babai, Philine abyssicola, Retusa diaphana, Retusa insolita, Retusa lenis, Retusa abyssicola, Retusa trunca, Volvulella onoae, Volvulella multistriata, Relichna hadra and Micratys wareni. A previously described species, Acteon aequatorialis, is included in the new genus Bathyacteon. Three species are assigned provisionally to already described species until more material becomes available: Acteon cf. nakayamai, Maxacteon cf. kawamurai, “Acteon” laetus. Thirty-eight species remain unnamed because of the absence of adequate information, but the shells are illustrated. Most species are described based on conchological data. Fourteen species of Acteonidae and two of Retusidae are provisionally assigned to the artifi cial taxa “Acteon” and “Retusidae” until anatomical data become available. The present collecting effort in the southwest Pacifi c has produced large numbers of previously undocumented species. The largest number of species was found in the area comprising the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna, which is probably a consequence of a greater collecting effort. The list of species refl ects a high degree of endemism in the deep sea fauna from the southwest Pacifi c. Only a few widespread Indo-Pacific species have been found in the deep sea. It also appears that there is some sort of isolation between the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna region and the Philippines and Indonesia region, which is refl ected in the small number of species shared between these two areas. Most species of “cephalaspidean” heterobranchs studied here have broad bathymetric ranges compared to other groups of opisthobranchs, which may be a result of a higher ecological adaptability of this group, or may be an artifact caused by transport of empty shells. When only specimens collected alive are considered, the bathymetric ranges of most species are considerably narrower. Most species studied are exclusively found in the deep sea, but a small number of shallow water species have been recorded here for the fi rst time in deep waters. When the ranges of empty shells are examined there appears to be a turnover of “cephalaspidean” heterobranch species at about 1000-1200 m depth and a blurry transition between shallow waters and the deep sea. When only specimens collected alive are considered, there is a sharp boundary at about 200 m that clearly separates the shallow water and the deep sea faunas. “Cephalaspidean” heterobranch species are more common relative to other groups of opisthobranchs in deep waters than in shallow waters, but this result may be an artefact caused by the collecting techniques.

Centroscymnus coelolepis is a deep-water sleeper shark and, like most sharks, it is covered in placoid scales, or dermal denticles. The morphological diversity of the dermal denticles in this species, however, has not been described in detail, and ontogenetic changes in denticle morphology are poorly understood in sharks. Combining scanning-electron microscopy and micro-CT imaging, we demonstrate the presence of eleven dermal-denticle morphotypes across the ontogeny and different regions of the body of Centroscymnus coelolepis. The snout, interspiracular, and trunk/tail regions have similar changes in denticle morphotype during development. For example, on the trunks and tails of juveniles (~350 mm TL), denticle crowns have two to three longitudinal ridges and three posterior cusps that are gradually replaced by ridgeless and cuspless crowns in adults (>800 mm TL). Sixteen measurements were obtained from the 3D models generated. A principal component analysis demonstrated that the eleven distinct dermal-denticle morphotypes observed were located in different regions of the morphospace. The denticle volume and surface area showed negative allometry with respect to body length throughout the ontogeny. The results reflect the considerable diversity within the denticle multiverse (ontogenetic and intraspecific variations), and much of this diversity remains to be explored to fully understand the role of dermal denticles in shark taxonomy, ecology, and biomechanics.

The genera Cantharus Röding, 1798, Pollia Gray in Sowerby, 1834, and Cancellopollia n.g. (type species : C. gracilis n. sp.) are pisaniine buccinids having a small tooth (labral spine) at the edge of the crenulated outer lip. As defined and restricted here, these genera have a mainly Indo-West Pacific distribution. Cantharus septemcostatus n. sp. , Pollia pellita n. sp., Cancellopollia gracilis n. sp. , and C. ustulata n. sp., are reported from deep water in the New Caledonia region, and Cantharus leucotaeniatus Kosuge, 1985 and Pollia vicdani (Kosuge, 1984) n. comb. are from the Vanuatu. Despite a narrow bathymetric (4154-560 m) and horizontal (northernmost Norfolk Ridge) distribution, Cancellopollia gracilis exhibits remarkable variation, with highly localised morphs.

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

The fauna of the tropical Indo-west Pacific is exceptionally diverse but poorly known with even relatively well-studied faunal components yielding new species after careful study, novel approaches (e.g., delineation of cryptic species via molecular analyses) and/or rigorous collection efforts. In an attempt to quantify the biodiversity of the western Pacific molluscan fauna, comprehensive, systematic collecting expeditions have been made since 1978, with a focus on New Caledonia. Building on earlier studies of cardiids from the western Pacific, we report one new genus of cardiid (Pseudofulvia n. gen.) and 10 new cardiid taxa from the area: Acrosterigma capricorne n. sp., Fulvia (Fulvia) colorata n. sp., F. (F.) vepris n. sp., F. (Laevifulvia) subquadrata n. sp., F. (L.) imperfecta n. sp., Pseudofulvia caledonica n. gen., n. sp., P. arago n. gen., n. sp., Ctenocardia gustavi n. sp., C. fi jianum n. sp., C. (Microfragum) subfestivum n. sp. The new species are easily differentiated from conspecifics in details of hinge, dentition, lunular shape and area, rib number and/or rib ornamentation, but often diff er in gross morphological features, such as coloration, shape and size as well. Ctenocardia gustavi n. sp., C. (Microfragum) subfestivum n. sp. and Pseudofulvia caledonica n. gen., n. sp. are relatively large-bodied, with a wide distribution throughout the western Pacifi c. In contrast, Acrosterigma capricorne n. sp. and Pseudofulvia arago n. gen., n. sp. are known only from the Austral Islands and considering the intensive collecting efforts in the region, they appear restricted in their distributions.

Low coverage ‘genome-­skims’ are often used to assemble organelle genomes and ribosomal gene sequences for cost-­effective phylogenetic and barcoding studies. Natural history collections hold invaluable biological information, yet poor preservation resulting in degraded DNA often hinders polymerase chain reaction-­based analyses. However, it is possible to generate libraries and sequence the short fragments typical of degraded DNA to generate genome-­skims from museum collections. Here we introduce a snakemake toolkit comprised of three pipelines skim2mito, skim2rrna and gene2phylo, designed to unlock the genomic potential of historical museum specimens using genome skimming. Specifically, skim2mito and skim2rrna perform the batch assembly, annotation and phylogenetic analysis of mitochondrial genomes and nuclear ribosomal genes, respectively, from low-­coverage genome skims. The third pipeline gene2phylo takes a set of gene alignments and performs phylogenetic analysis of individual genes, partitioned analysis of concatenated alignments and a phylogenetic analysis based on gene trees. We benchmark our pipelines with simulated data, followed by testing with a novel genome skimming dataset from both recent and historical solariellid gastropod samples. We show that the toolkit can recover mitochondrial and ribosomal genes from poorly preserved museum specimens of the gastropod family Solariellidae, and the phylogenetic analysis is consistent with our current understanding of taxonomic relationships. The generation of bioinformatic pipelines that facilitate processing large quantities of sequence data from the vast repository of specimens held in natural history museum collections will greatly aid species discovery and exploration of biodiversity over time, ultimately aiding conservation efforts in the face of a changing planet.

Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still few in number. In this study, we had access to the largest number of solariellid gastropods ever collected for molecular studies, including many rare and unusual taxa. We used a Bayesian chronogram of these deep-sea gastropods (1) to test the hypothesis that deep-water communities arose onshore, (2) to determine whether Antarctica acted as a source of diversity for deep-water communities elsewhere and (3) to determine how factors like global climate change have affected evolution on the continental slope. We show that although fossil data suggest that solariellid gastropods likely arose in a shallow, tropical environment, interpretation of the molecular data is equivocal with respect to the origin of the group. On the other hand, the molecular data clearly show that Antarctic species sampled represent a recent invasion, rather than a relictual ancestral lineage. We also show that an abrupt period of global warming during the Palaeocene Eocene Thermal Maximum (PETM) leaves no molecular record of change in diversification rate in solariellids and that the group radiated before the PETM. Conversely, there is a substantial, although not significant increase in the rate of diversification of a major clade approximately 33.7Mya, coinciding with a period of global cooling at the EoceneOligocene transition. Increased nutrients made available by contemporaneous changes to erosion, ocean circulation, tectonic events and upwelling may explain increased diversification, suggesting that food availability may have been a factor limiting exploitation of deep-sea habitats. Tectonic events that shaped diversification in reef-associated taxa and deep-water squat lobsters in central Indo-West Pacific were also probably important in the evolution of solariellids during the Oligo-Miocene.

Material previously identified as Galearctus kitanoviriosus (Harada, 1962) from New Caledonia has been found to consist of two distinct species. These species differ in the shape of the gastric tooth, third pereiopod propodus, antennal segment IV and thoracic sternum. The shallow water form is the true G. kitanoviriosus, while the deep-water form is new to science. Genetic comparison of the sequence of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), also supports the separation.

The slipper lobsters belong to the family Scyllaridae which contains a total of 20 genera and 89 species distributed across four subfamilies (Arctidinae, Ibacinae, Scyllarinae, and Theninae). We have collected nucleotide sequence data from regions of five different genes (16S, 18S, COI, 28S, H3) to estimate phylogenetic relationships among 54 species from the Scyllaridae with a focus on the species rich subfamily Scyllarinae. We have included in our analyses at least one representative from all 20 genera in the Scyllaridae and 35 of the 52 species within the Scyllarinae. Our resulting phylogenetic estimate shows the subfamilies are monophyletic, except for Ibacinae, which has paraphyletic relationships among genera. Many of the genera within the Scyllarinae form non-monophyletic groups, while the genera from all other subfamilies form well supported clades. We discuss the implications of this history on the evolution of morphological characters and ecological transitions (nearshore vs. offshore) within the slipper lobsters. Finally, we identify, through ancestral state character reconstructions, key morphological features diagnostic of the major clades of diversity within the Scyllaridae and relate this character evolution to current taxonomy and classification.
