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

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

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.

The bothid genus Tosarhombus is reviewed by comparing four species : T. octoculatus Amaoka, 1969, T. smithi (Nielsen, 1964), T. nielseni sp. nov. and T. neocaledonkus sp. nov. A description of the genus is given in addition to descriptions and a key to the four species. T. smithi from the western Indian Ocean is transferred from the genus Engyprosopon based on high numbers of dorsal fin rays, anal fin rays, lateral-line scales and total vertebrae, unsplit parhypural and hypural plates, and the tip of isthmus not extending to the middle part of the lower eye. T. nielseni sp. nov. From Saya de Malha Bank, western Indian Ocean and T. neocaledonicus sp. nov. From the Chesterfield Islands, west of New Caledonia, are described based on several male and female specimens. The former new species is distinguished by having the posterior 2/3 of the body on the ocular side in males colored pale violet, short pectoral fin on the ocular side (1.7-2.0 times in head length), and a long snout and upper jaw on the blind side (4.4-4.7 times and 2.5-2.6 times in head length respectively). The latter new species has a high number of scales in lateral line (more than 80). And the filamentous pectoral fin ray on the ocular side of males.

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

Species of the bothid genus Engyprosopon Günther, 1862 from the waters off Taiwan are reviewed. Nine species are recognized and described. Of the nine species, E. grandisquama (Temminck & Schlegel, 1846), E. multisquama Amaoka, 1963 and E. maldivense (Regan, 1908) previously known from Taiwan are confirmed, whereas E. xystrias Hubbs, 1915, E. mogkii (Bleeker, 1854), E. longipelvis Amaoka, 1969 and E. mozambiquense Hensley, 2003 represent new records for Taiwan. Moreover, two further species are described new to science. Engyprosopon brevifrontale sp. nov. is characterized by a deep and short body, large eyes situated close to the head margin, 0 + 9–10 smooth gill rakers, strong rostral and upper orbital spines on the ocular side, small rostral spine on the blind side, and a dark blue peritoneum. Engyprosopon parvipectorale sp. nov. is characterized by the combination of serrate gill rakers, large head (3.1–3.4 in SL); extremely narrow or almost ridge-like interorbital in both sexes; ocular-side pectoral fin distinctly short (1.4–1.6 in HL) in both sexes; and no rostral or orbital spines in either sex. Detailed descriptions and a key to all of the species of Engyprosopon recorded from the waters off Taiwan are provided.

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

Five new species of the family Isididae from New Caledonian waters are described together with comparative material from elsewhere in the western Pacific Ocean. By comparison with specimens from Australia, the Philippines, Taiwan and the Ryukyu Islands, the population of Isis in New Caledonia is considered to be within the range of variation of Isis hippuris Linnaeus. Mopsea bargibanti, M. laboutei and M. provocatoris are described as new to science and compared with M. whiteleggei from Australia. The genus Acanthoisis Studer and Wright, previously treated as a synonym of Mopsea Lamouroux, is restored to validity as a distinct genus. Acanthoisis richerdeforgesi and A. dhondtae are described as new and compared with the type-species of the genus, A. flabellum Wright and Studer, which is considered as a probable senior subjective synonym of Mopsea simplex Tixier-Durivault. The genus Sclerisis Studer, previously treated as a questionable synonym of Primnoisis Studer and Wright, is restored to validity and a new species, Sclerisis macquariana, is described from south of New Zealand. A revised key to the genera of the family Isididae and a key to the genera and species known or expected in New Caledonian waters are presented.

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

Cassis abbotti n. sp. is characterized by a smooth polished shell, a poorly developed parietal shield, a narrow aperture with denticulated inner and outer lips, and a bulbous, paucispiral protoconch. It is possibly endemic to the Chesterfield Bellona Plateau, where the holotype was taken in 205 m. The family Cassidae has been monographed in part by Abbott (1968) who recognized about 60 Recent species, the majority of which are Indo-Pacific. The higher classification of the Tonnoidea is revised by Beu (1981) and Waren and Bouchet (MS), and Marum has l~ecently been transferred to the neogastropod family Harpidae (Hughes, 1986) . That the alpha-taxonomy of the family has reached a phase of stability is evidenced by the fact that fewer than 5 taxa in the Cassis-Phalium group have been described or changed status in the 20 years since Abbott's revision. The discovery of a very distinct new Cassis from a depth of 205 m in the Coral Sea was therefore unexpected, and raises questions on generic limits within the family.

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

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.

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

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

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

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

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

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

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

A taxonomic review of the waspfish genus Neocentropogon Matsubara 1943 (Tetrarogidae), diagnosed by the following combination of characters: body sparsely covered with small embedded cycloid scales, palatine teeth present, XIII–XVI dorsal-fin spines, the first dorsal fin originating above the orbit, five pelvic-fin soft rays, and membrane of lower four pectoralfin rays deeply incised, resulted in the recognition of six species: Neocentropogon aeglefinus (Weber 1913), Neocentropogon affinis (Lloyd 1909a), Neocentropogon japonicus Matsubara 1943, Neocentropogon mesedai Klausewitz 1985, Neocentropogon profundus (Smith 1958), and Neocentropogon trimaculatus Chan 1966. Neocentropogon trimaculatus (anti-tropically distributed in East Asia and Australia) can be distinguished from its congeners by the presence of three dark blotches on the body (vs. absent or a single blotch); N. affinis (eastern Indian Ocean) and N. aeglefinus (Philippines to Australia) differ from other congeners in having a black blotch behind the opercle (vs. blotch absent), with the former distinguishable from the latter by dorsal rows of dark spots on the body, and pectoral and caudal fins (vs. spots absent), and 79–96 scale rows in the longitudinal series (vs. 94–137); N. mesedai (Red Sea) differs from N. profundus (southwestern Indian Ocean) and N. japonicus (northwestern Pacific Ocean) in having the lowermost four pectoral-fin rays elongated and XIII (vs. XIV–XVI) dorsal-fin spines, the latter species being separated by the symphyseal knob condition (unremarkable, N. profundus vs. pronounced, N. japonicus), dark dorsal spots on the body (vs. absent), and 5 anal-fin soft rays (vs. 6 or 7). Keys to the genera of Tetrarogidae and species of Neocentropogon are given, including taxonomic status of Vespicula Jordan and Richardson 1910 and Pseudovespicula Mandrytsa 2001.

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.

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

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

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

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

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.

Le benthos profond récolté tout d'abord lors des campagnes océanographiques MUSORSTOM IV (1) et CHALCAL (2), puis lors des campagnes de récoltes SMlB (1986, 1987, 1989) s'est avéré être extrèmement riche en invertébrés divers dont beaucoup sont nouveaux. L'abondance et l'originalité de cette faune nous a conduit à étudier une cinquantaine d'organismes recoltés entre 200 et 700m: éponges (40), échinodermes (1 O), alcyonaires (2), madréporaires (1).

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

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

The 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.

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

Phos alabastrum sp. nov. and P. boucheti sp. nov. are characterized by a striking bicarinate protoconch, a character they hâve in common with the Carribean species oï Antillophos Woodring, 1928. The colour of the protoconch and the absence of strong sculpture on the teleoconch distinguish both species from the Australian P. sciilptilis Watson, 1886. P. deforgesi sp. nov. differs from the preceding species and from some species of H inia (Nassariidae) in having a siphonal notch.

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.

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

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

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

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.

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

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

All species of Umboniinae known to occur in New Caledonia are discussed (19 species, 8 new, belonging to 10 genera, 2 new) and a key to genera is provided. An additional new species is described from the Bismarck Sea. Nine species are perhaps endemic to New Caledonia. The diversity of the fauna is comparable to that of Japan and Australia, both regions of much greater extent and spanning a much broader latitudinal range. Ethalia lampra (Watson, 1880), previously known only from the original HMS Challenger material from Fiji, has been rediscovered in New Caledonia. Re-examination of the type material of Monilea apicina Gould, 1861 has led to a re-interpretation of the application of this name. Type specimens of a number of additional umboniine species examined for comparison are illustrated. Two new genera are proposed: Kanakina gen. nov. and Tylorhaphe gen. nov. Nine new species are described: Ethalia anomphala sp. nov., Ethminolia hickmanae sp. nov., Sericominolia porcata sp. nov., S. safrocincta sp. nov., Talopena maestratii sp. nov., Tylorhaphe alisae gen. et sp. nov., T. fritillaria gen. et sp. nov., T. luteopicta gen. et sp. nov. and T. wallacei gen. et sp. nov. Revised status: Talopena Iredale, 1918 is recognised as a full genus rather than a subgenus or synonym of Monilea Swainson, 1840. Minolia agapeta Melvill & Standen, 1896 is considered a distinct species, no longer to be regarded as a junior synonym of Monilea apicina Gould, 1861. Trochus (Monilea) lifuanus Fischer, 1878 is considered a distinct species, no longer to be regarded as a junior synonym of Monilea vernicosa Gould, 1861. New combinations: Monilea incerta Iredale, 1912 is reassigned to Talopena Iredale, 1918; Monilea apicina Gould, 1861, Monilea menkei A. Adams, 1855, Monilea philippii A. Adams, 1855, Pseudominolia tramieri Poppe, Tagaro & Dekker, 2006, Trochus belcheri Philippi, 1850, Trochus calyculus W. Wood, 1828, and Trochus (Monilea) masoni G. Nevill & H. Nevill, 1874 are all referred to Talopena Iredale, 1918. Minolia glaphyrella Melvill & Standen, 1895 is transferred to Kanakina gen. nov. Type localities: Nouméa, New Caledonia is designated as the type locality for Trochus nucleus Philippi 1850; the type locality ‘Port Jackson’ originally given for Monilea apicina Gould, 1861 is considered erroneous and is emended to Lansdowne Bank. New records for New Caledonian marine ecoregion: Ethalia lampra (Watson, 1880), Talopena apicina (Gould, 1861) and ‘Talopena’ tramieri (Poppe, Tagaro & Dekker, 2006).

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.

A new species of platycephalid, Onigocia lacrimalis, is described on the basis of specimens collected from the Chesterfield Islands (Coral Sea) and Norfolk Ridge (Tasman Sea), at depths of 111–330 m. Onigocia lacrimalis differs from the six congeners of the genus in having 12–13 (usually 12) second dorsal-fin rays, 12 anal-fin rays, 21–25 pectoral-fin rays, 8 branched caudal-fin rays, anterior 2–4 scales of the lateral line with a spine, and a single preocular spine, and in lacking gill rakers on the upper arch, ocular and interopercular flaps, and distinct antrorse lachrymal spines.

A total of 17 species, in 14 genera of majids have been examined for sperm ultrastructure. The present account describes the sperm of six of these species, in two subfamilies: Pisinae Sphenocarcinus orbicularus and Sphenocarcinus stuckiae and Inachinae-Cyrtomaia furici, Gypacheus hyalinus. Flatymaia rebierei and Macropodia longirostris. M. longirostris has the only eubrachyuran sperm in which the acrosome is known to depart radically from a subspheroidal form. The acrosome is semilunar in shape and is bordered by a very thin layer of cytoplasm and an unusually uniform, narrow band of chromatin. The apical surface of the acrosome is almost flat, though slightly concave, whereas the posterior surface forms a hemisphere, and is almost completely occupied by the thin, centrally perforate, electron dense operculum. The bulk of the acrosome consists of a homogeneous, moderately electron dense outer acrosome zone. This surrounds a small inner acrosome zone internal to which is an ellipsoidal, pale perforatorium capped by a central acrosome zone. Majid sperm are distinguished by a flattened andlor centrally depressed operculum; a further characteristic is that the pointed perforatorium is relatively short and frequently does not reach the operculum. They vary inter alia with regard to presence or absence of a posterior median process and, apparently. Of centrioles and of microtubules in the nuclear arms, and in the number of these ams. Perforation of the operculum, seen in the Pisinae, is not constant in the Inachinae. Spermatozoal ultrastructure offers no certain support for a close relationship of majids with parthenopids or hymenosomatids.

Les espèces les plus communes de crustacés décapodes et stomatopodes de Nouvelle- Calédonie ont été photographiées en mars 2009 dans 3 stations principales : en Province Sud, aux environs de Nouméa et sur les îlots Rédika et Ka ; en Province Nord, entre la presqu'île de Pindaï et Voh ; et aux îles Loyauté, à Lifou. Au total 19 stations ont été visitées en pêche à pied à basse-mer ou en plongée sous-marine sur des fonds de 1-20 m, de jour et de nuit. Une petite collection de référence a été constituée pour un examen au laboratoire nécessaire à certaines déterminations. Cette récolte est déposée dans les collections du Muséum national d'Histoire naturelle de Paris. Les photographies des auteurs réalisées in situ ou au laboratoire ont été complétées avec celles d’une dizaine de plongeurs photographes ayant accepté de participer à ce projet de recherche. La photothèque ainsi constituée comprend plus de 600 clichés exploitables, correspondant à 176 espèces différentes. Ces photographies sont présentées sur des planches photographiques pour servir d’aide à la détermination aux gestionnaires de l’environnement marin de Nouvelle-Calédonie et aux plongeurs photographes amateurs. Les espèces sont présentées par ordre alphabétique sur des planches regroupées par grands groupes taxonomiques : stomatopodes et langoustes, crevettes, bernard l’ermite, et crabes. Les déterminations provisoires sont indiquées par 'cf.' Parallèlement à cet inventaire photographique, une liste documentée préliminaire des espèces de crustacés stomatopodes et décapodes terrestres et de petits fonds, en excluant les espèces toujours récoltées au-delà de 100 m, est proposée pour la Nouvelle-Calédonie et les archipels voisins (Chesterfield, Entrecasteaux, Loyauté). Cette liste a été compilée en collaboration avec B. Richer de Forges et C. Hoffschir du centre IRD de Nouméa à partir des données de la BD 'Océane', complétées par les nouveaux signalements effectués au cours de ce travail et une recherche bibliographique supplémentaire. Elle comprend 939 espèces pour lesquelles sont indiquées : profondeurs minimale-maximale, au moins une référence bibliographique attestant de sa présence en Nouvelle-Calédonie, la liste des campagnes de prospection concernées et des lieux-dits de récolte.

The Polyplacophora from seven French cruises in the western tropical Pacific (Philippines, Coral Sea and New Caledonia), during the years 1980-1986, are discussed. Altogether 17 samples of chitons contain 29 specimens, belonging to 11 species, 4 of which are new, viz. Notoplax richen; N. richardi, N. rostellata and Ischnochiton (Stenosemus) per/oratus. Two other species, hitherto only known from the Queensland coast, viz. Leptochiton (Parachiton) capricornicus (Iredale & Hull, 1925) and Callistochiton granifer Hull, 1923, were obtained in the Coral Sea (Capel Bank and Chesterfield-Bellona) at a depth of little more than 50 m.

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.

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

Species of the genus Clavus of the conoidean family Drilliidae that occur in the littoral and shallow waters of New Caledonia are here revised. This study is based primarily on recent expedition material from the Institut de Recherche pour le Développement (New Caledonia) and Muséum National d’Histoire Naturelle (France). A total of 22 species is recorded, of which eight are described as new. New species: Clavus boucheti, Clavus delphineae, Clavus virginieae, Clavus picoides, Clavus squamiferus, Clavus devexistriatus, Clavus hylikos, Clavus maestratii; New synonyms: Tylotiella Habe, 1958 = Clavus; Clavus leforestieri Hervier, 1896 = Pleurotoma obliquicostata Reeve, 1845; Pleurotoma mariei Crosse, 1869 = Pleurotoma lamberti Montrouzier, 1860; Clavus mighelsi Kay, 1979, new name for Pleurotoma acuminata Mighels, 1845, non J. Sowerby, 1816, was misidentified by Kay 1979; the lectotype of P. acuminata Mighels, 1845, is mangeliine. Clavus mighelsi sensu Kay 1979, is a synonym of Pleurotoma humilis E. A. Smith, 1879. It is suggested that Pleurotoma pulchella Reeve, 1845, sometimes treated as an Indo-Pacific species, may be a senior synonym of Fenimorea halidorema Schwengel, 1940, from the tropical western Atlantic. Nomen dubium: Pleurotoma mediocris Deshayes, 1863.

A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduced species. The native fi sh fauna of New Caledonia therefore consists of 2320 species in 241 families. The largest families are the Gobiidae, Labridae, Pomacentridae, Serranidae, Apogonidae, Blenniidae, Macrouridae, Myctophidae and Muraenidae. The freshwater fi sh fauna is dominated by the families Gobiidae, Eleotridae, Anguillidae and Mugilidae. A total of 61 species represent new records from New Caledonia. The fish fauna from New Caledonia includes a total of 125 species occurring in freshwater (plus eight introduced species), 266 (plus two introduced) species in transitional (brackish) waters, and 2320 marine species. The detailed geographical distribution of the New Caldonian fi sh species including the southern submarine ridges (Lord Howe Island, Norfolk Island, New Zealand) is provided. Among the New Caledonian marine species, 905 are recorded from the East Coral Sea including Chesterfi eld Islands, 193 from the New Caledonian basin, 1860 from the Grande Terre group, 85 from the Norfolk Ridge, and 1029 from the Loyalty Ridge including Loyalty Islands. New Caledonia has a considerable endemic element of 107 species (4.6 % of the total native 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.

The Indo-West Pacific venerid genus Lioconcha is reviewed, with special emphasis on species occurring in the Australian and New Caledonian regions. Nineteen species, including four new species, are recognised: Lioconcha castrensis (Linnaeus, 1758), L. macaulayi n. sp., L. hieroglyphica (Conrad, 1837), L. tigrina (Lamarck, 1818), L. fastigiata (Sowerby, 1851), L. annettae Lamprell & Whitehead, 1990, L. pseudofastigiata n. sp., L. ornata (Dillwyn, 1817), L. berthaulti n. sp., L. sowerbyi (Deshayes, 1853), L. polita (Röding, 1798), L. schioettei n. sp., L. trimaculata (Lamarck, 1818), L. philippinarum (Hanley, 1844), L. dautzenbergi (Prashad, 1932), L. melharteae Lamprell & Stanisic, 1996, L. caledonensis Harte & Lamprell, 1999, L. richerdeforgesi Lamprell & Stanisic, 1996 and L. gordoni (E. A. Smith, 1885). Colour variation within species ranges from very high (L. ornata, L. castrensis) to very low (L. melharteae, L. caledonensis, L. philippinarum). All species are figured, diagnosed and discussed and a key is presented. Types of the following taxa are also figured: neotype of Venus ornata Dillwyn, 1817; holotypes of Lioconcha berthaulti n. sp.; L. macaulayi n. sp.; L. pseudofastigiata n. sp.; L. schioettei n. sp.; L. annettae Lamprell & Whitehead, 1990; Cytherea tigrina Lamarck, 1818; Hysteroconcha (?Lamelliconcha) dautzenbergi Prashad, 1932 and Cytherea sulcatina Lamarck, 1818; lectotypes of Cytherea hebraea Sowerby, 1851 and Circe sowerbyi Deshayes, 1853. Lectotypes of Cytherea hieroglyphica Conrad and C. fastigiata Sowerby are based on original figures, in the absence of other undoubted type material. Subdivision of Lioconcha into two subgenera (Lioconcha sensu stricto and Sulcilioconcha), based solely on the presence or absence of concentric ridge sculpture, appears unwarranted.

La caractérisation du substrat des fonds marins est une première étape fondamentale pour la prédiction des habitats benthiques, la gestion des ressources biologiques ou encore l’inventaire des ressources minérales. Ce travail est d’autant plus essentiel lorsque l’on traite la Zone Economique Exclusive (ZEE) de Nouvelle-Calédonie considérée, à l’échelle globale, comme une des régions les plus riches en termes de biodiversité marine. Ce stage, qui a pour but de cartographier la nature des fonds de la ZEE, s’inscrit dans le cadre du projet de mise en place d’une politique de « gestion intégrée de l’Espace maritime de la Nouvelle-Calédonie ». La méthodologie employée pour répondre à cet objectif a consisté à traiter l’ensemble des données d’imagerie acoustique acquises pour la plupart au cours des campagnes ZoNéCo et à les corréler aux prélèvements disponibles. Ce travail a permis de réaliser la carte de réflectivité des fonds marins couvrant 34 % de la ZEE et la mise à jour de la base de données des prélèvements comptabilisant aujourd’hui plus de 880 échantillons. L'examen approfondi de ces nouvelles données a permis de créer une classification adaptée à la Nouvelle-Calédonie s'inspirant des normes européennes EUNIS. Au final, deux cartes ont été produites : (i) une carte présentant la dureté des fonds marins de la ZEE et (ii) une carte présentant la nature et le type de substrat de la ZEE. Ces nouveaux résultats révèlent la présence de grands ensembles sédimentaires et la découverte de nouvelles structures géologiques. Sur un plan appliqué, ce travail a amélioré la connaissance des ressources minérales de la ZEE et a permis de créer les couches d’informations utiles aux futurs travaux de prédiction des habitats benthiques marins. Il a enfin été l’occasion de dresser des préconisations visant à réduire les incertitudes et orienter les travaux futurs.

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 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.

Galatheid crustaceans of the genus Paramunida Baba, 1988, collected in the Philippines, Indonesia and New Caledonia, have been studied. The collection contains 12 species, seven of which are described as new : P. belone, P. evexa, P. pictura, P. polita, P. pronoe, P. stichas, and P. thalie. An identification key for all of the species of the genus is provided.

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

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

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.

A revision of the genus Sadayoshia Baba, 1969 (type species: S. miyakei Baba, 1969) is carried out based on more than 460 specimens from numerous localities in the Indo-Pacific, revealing the existence of seven species. Sadayoshia edwardsii (Miers, 1884) is redescribed using material collected near the type locality (SW Indian Ocean) and from numerous localities from the Indian and Pacific Oceans. The three previously described species (S. acroporae, S. balica, and S. miyakei) proved to be valid species. Four additional species are described here as new to science: S. latisternata n. sp. from French Polynesia, Loyalty Islands and Mauritius Island; S. lipkei n. sp. from French Polynesia, Solomon Islands, Vanuatu, New Caledonia, Loyalty Islands and Chesterfield Islands; S. inermis n. sp. from Solomon Islands, Vanuatu and New Caledonia; and S. tenuirostris n. sp. from Japan, South China Sea, Palau Islands, Philippines, Indonesia, Solomon Islands, Vanuatu and New Caledonia.

Careful examination of the morphology of recently obtained specimens as well as previously reported specimens of the genus Sadayoshia, initiated by unpublished molecular data that suggest the existence of several different species, led us to describe six new species. The species are very similar to one another and distinguished by very slight morphological differences. Some of the characters that were previously considered as intraspecifically variable in some species, proved to be valid for species discrimination. A dichotomous key to all species of the genus is provided.

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

Gigantione petalomerae sp. nov. infests the dromiid crab Petalomem pulchra Miers in New Caledonia. Two species of Pseudione show new host and geographic records: P. nephropsi Shiino, 1951, infests Metanephropsis velutiniis Chan & Yu at Tanimbar Islands, Indonesia; P. elongata elongata (Hansen, 1897) infests Neinatocarcinus sp. in Chesterfield Islands; both species are redescribed in detail. Pseudione taniinbarensis, sp. nov. infests Nephropsis sulcata Macpherson at Tanimbar Islands, Indonesia. As a result of these redescriptions, the subspecies P. nephropsi atlantica Bourdon, 1971, is considered a separate species, Pseudione atlantica Bourdon, 1971, and the variety P. elongata var. norinalis Nierstrasz & Brender à Brandis, 1931, is considered invalid.

Thirty species (27 new) of Calliostomatidae are recorded from the study region, all but two of which are new records. An additional new species is based on material from northern New Zealand. They are referred to Fautor Iredale, 1924, Benthastelena Iredale, 1936, Ampullotrochus Monterosato, 1890 (as subgenera of Calliostoma Swainson, 1840), Bathyfautor gen. nov., Dactylastele gen. nov., Laetifautor Iredale, 1929, Selastele gen. nov., Fautrix gen. nov., and Thysanodonta Marshall, 1988. A new tribe, Fautricini, is introduced for species with a radula that is evidently the most primitive (plesiomorphic) in the family, and Fautricini either represents the common basal stock or an early offshoot from it. Calliostomatidae is treated as a family within Trochoidea rather than a subfamily of Trochidae as has been traditional. Three calliostomatid genus group taxa are newly synonymised: Tristichotrochus Ikebe, 1942 ( = Benthastelena Iredale, 1936), Salsipotens Iredale, 1924 (= Astele Swainson, 1840), Spicator Cotton & Godfrey, 1935 ( = Laetifautor Iredale, 1929). Criteria used for taxonomic discrimination, evolutionary history, and some biogeographical observations are discussed. All calliostomatid genus group taxa and taxa removed (some newly) from the family are listed in appendices. A lectotype is designated for Zizyphinus scobinatus A. Adams, 1863.

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

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

A new species in each of two recently proposed genera are described and illustrated: Alainopaguroides megalophthalmus n. sp., Icelopagurus undulatus n. sp. The new species assignable to Alainopaguroides McLaughlin expands the range of this genus from the Kai and Tanimbar Islands of Indonesia and the Andaman Sea to New Caledonia. Similarly, the discovery of a new and readily recognizable species belonging to the heretofore monotypic Icelopagurus McLaughlin extends the distribution of this genus from Indonesia to New Caledonia. The diagnoses of both genera have been emended slightly to accommodate the interspecific variation exhibited by the taxa now included.

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

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

Five species of the samarid genera Plagiopsetta and Samaris: P. stigmosa n. sp., P. gracilis n. sp., S. cristatus Gray, 1831, S. spinea n. sp. and S. chesterfieldensis n. sp., collected from New Caledonia and adjacent waters are described and keys to the species provided. Plagiopsetta stigmosa is easily separable from its congeners by having lateral lines on both sides and the pectoral fin with a jet-black blotch. Plagiopsetta gracilis is characterized by a uniformly dark pectoral fin, shallow body and caudal peduncle, a short ocular side pelvic fin, and large numbers of dorsal fin rays, anal fin rays, scales in the lateral line and vertebrae. Samaris spinea and S. chesterfieldensis are both characterized by caudal peduncle spines and bifurcated middle caudal fin rays, and are also separable by body depth.

A new scorpionfish, Phenacoscorpius longilineatus n. sp., is described on the basis of 94 specimens from New Caledonia and New Zealand in the southwestern Pacific Ocean, at depths of 345–1089 m. The new species is distinguished from its congeners by the following combination of characters: 8–18 (mode 12) pored lateral-line scales, last of which is situated from below base of seventh spine to below base of fourth dorsal-fin soft ray; no slit behind fourth gill arch; palatine teeth present; second preopercular spine always absent; nuchal and parietal spines distinct; nape and anterior body strongly arched in adults of over ca. 80 mm standard length (SL); post-nuchal-spine length 5.0–9.7% (mean 7.2%) of SL; caudal fin length 21.4–26.7% (mean 23.4%) of SL; 1–5 (mode 2) black spots on posterior half of caudal peduncle; and body usually uniformly whitish without distinct dark saddles in preserved specimens. In addition, P. adenensis Norman, 1939, which is similar to P. longilineatus morphologically, is redescribed on the basis of 3 specimens from the western Indian Ocean and 52 specimens from the southwestern Pacific. The latter represent the first records of this species outside the western Indian Ocean.

A taxonomic review of the scorpaenid genus Pteroidichthys Bleeker, 1856 resulted in recognizing four valid species, including two new species; P. acutus n. sp., P. amboinensis Bleeker 1856, P. caussei n. sp., and P. noronhai (Fowler 1938). The genus Pteropelor Fowler, 1938 is regarded as a junior synonym of Pteroidichthys. Rhinopias godfreyi Whitley 1954, previously treated as a valid species, is herein regarded as a junior synonym of P. amboinensis. Pteroidichthys amboinensis and P. caussei have two spines and six soft rays in the anal fin and a supplemental preopercular spine, whereas P. acutus and P. noronhai have three spines and five rays, and lack the spine. Pteroidichthys amboinensis differs from P. caussei in having flexible dorsal-fin spines (vs. rigid in the latter) and tentacles on the supraocular and posterior lacrimal spines well developed, their lengths greater than the orbit diameter (vs. less than orbit diameter). Pteroidichthys noronhai differs from P. acutus in having a relatively short snout, its length shorter than (vs. longer than in the latter) the postorbital length, and a distance between tips of the lateral lacrimal and first suborbital spines shorter than or subequal to (vs. longer than) that between tips of the first and second suborbital spines. Pteroidichthys acutus is known from the western Pacific in depths of 73–400 m, P. amboinensis from the Indo-West Pacific in 7–43 m, P. caussei from the South Pacific in 68–122 m, and P. noronhai from the western Pacific and Western Australia in 52–215 m.

A new species of Pleurotomariid gastropod, Perotrochus deforgesi n. sp. Dredged from the Chesterfield-Bellona Plateau, Coral Sea, is described. This new species is characterized by having depressed shell, strongly beaded spiral cords and discrete orange blotches that are restricted to below the selenizone. This is the third species of the genus Perotrochus recorded from SW Pacific.

Deep-water trawl surveys on seamounts around New Caledonia yielded 62 specimens of the little-known genus, Scaeurgus. Members of this genus of octopuses typically occur at depths of 200-500 m in temperate and tropical latitudes worldwide. Prior to this study, Scaeurgus was considered to contain one to two species. The new material from New Caledonia contained a surprising diversity of Scaeurgus species from a small area: three distinct new species are described and limited material of a further two taxa is reported. A pygmy member of this genus is reported for the first time. Distributions of these new taxa are consistent with reports of high endemism on the seamount systems in this region. Fifty-eight of the 62 specimens were collected from seamounts, with four of the five taxa unique to a single seamount.

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].

A single specimen of the samarid flatfish, Samaris spinea Mihara and Amaoka, 2004, was collected off the northwest coast of Ototo-jima Island, Ogasawara Islands, Japan. This specimen represents the third occurrence of this species and the second record from Japan and the Northern Hemisphere. We report morphological characters of the specimen in detail with discussion of small spines along the dorsal and ventral margins of the caudal peduncle and the intermuscular bones. We confirmed the small spines coming out from large, plate-like scale. It is also revealed that distributional patterns of intermuscular bones of S. spinea are different from those of the congeneric species, S. cristatus: epimerals are absent and hypomerals are present only on abdominal and anterior caudal vertebrae in S. spinea. Although the present specimen bears a testis, male character as prolonged anterior dorsal- and pelvic-fin rays on ocular side is not appeared. This may be related to the presence of a single isopod parasite in the gill. The taxonomic confusion on gender of the generic name is also fixed.

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.

Squat lobsters have a worldwide distribution and are highly visible crustaceans living in a broad range of habitats. In this study, partial sequences of two mitochondrial DNA genes (16S rRNA and COI) and a nuclear gene (H3) were obtained for all but one of the known species of the shallow-water genera Sadayoshia (Munididae) and Lauriea, Macrothea and Triodonthea (Galatheidae). Lauriea siagiani appeared to be phylogenetically closer to Triodonthea and Macrothea than to other Lauriea species, suggesting the need for taxonomic re-evaluation of these taxa. All species of Sadayoshia formed a monophyletic group that would have diverged during the Paleogene (around 50 Mya). Our results support the hypothesis that the late Paleogene–Neogene transition was a period of rapid diversification for shallowwater species of both Galatheidae and Munididae in the Indo-Pacific region. This is probably related to high tectonic activity among the Eurasian, Philippine Sea, Indo-Australian and Pacific plates and corresponding changes in distribution of habitats and ocean currents during the late Paleogene. Finally, the tropical south-west Pacific province is identified as a major diversification centre for shallow-water squat lobsters, from where species dispersed to other Pacific and Indian Ocean regions.

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

This paper reports on deep water Pyramidellidae from the tropical South Pacific, collected during the Tropical Deep-Sea Benthos expeditions conducted by IRD and MNHN in New Caledonia, the Solomon Islands, Fiji, Tonga, Vanuatu, Wallis and Futuna, and French Polynesian, and deals more specifically with those species that can be included in the tribe Turbonillini. Since the different genera have not been thoroughly revised at the present time and there is no certainty about their validity, we have employed only the genus name Turbonilla in a broad sense. In total, 272 species are studied, of which 30 were already known, 33 were too poorly represented to be named and are presented as sp., and 209 are described as new to science. There is a clear decrease in species richness from the Solomon Islands (202 species) eastwards to Fiji (82 species), New Caledonia (85 species), Vanuatu (31 species), Tonga (11 species) and the Marquesas (7 species). Replacement names are proposed for Turbonilla gracilis (A. Adams, 1854) non Turbo gracilis Brocchi, 1814, and Exesilla sulcata Laseron, 1959, non Odostomia sulcata Garrett, 1873, both secondary homonyms in Turbonilla. New taxonomic opinions in this work are the following: Turbonilla theresa Thiele, 1925 and Pyrgiscus mirandus Saurin, 1959 are considered synonyms of Turbonilla funiculata de Folin, 1868; Odontostomia robusta Hedley, 1899, Turbonilla microscopica Laseron, 1959, and Turbonilla (Pyrgostelis) manorae Melvill, 1898 are considered synonyms of Turbonilla mumia (A. Adams, 1861); Turbonilla decussata Pease, 1861, T. elongata Pease, 1868, Proto cornelliana Newcomb, 1870, Chemnitzia coppingeri E. A Smith, 1884, Turbonilla (Lancella) bella Dall & Bartsch, 1906, and Turbonilla (Lancella) vitiensis Pilsbry, 1917 are considered synonyms of Turbonilla varicosa (A. Adams, 1855); Elusa secunda Saurin, 1959 is a synonym of Turbonilla ovalis de Folin, 1868; Turbonilla multigyrata Dunker, 1882 is a synonym of T. candida A. Adams, 1855; Turbonilla lydia Thiele, 1925 is a synonym of Turbonilla crystallina Dall & Bartsch, 1906.

The primary purpose of DNA-barcoding projects is to generate an efficient expertise and identification tool. This is an important challenge to the taxonomy of the 21st century, as the demand increases and the expert capacity does not. However, identifying specimens using DNA-barcodes requires a preliminary analysis to relate molecular clusters to available scientific names. Through a case study of the genus Eumunida (Decapoda : Eumunididae), we illustrate how naming molecule-based units, and thus providing an accurate DNA-based identification tool, is facilitated by sequencing type specimens. Using both morphological and unlinked molecular markers (COI and 28S genes), we analysed 230 specimens from 12 geographic areas, covering two-thirds of the known diversity of the genus, including type specimens of 13 species. Most hypotheses of species delimitation are validated, as they correspond to molecular units linked to only one taxonomic name (and vice versa). However, a putative cryptic species is also revealed and three entities previously named as distinct species may in fact belong to a single one, and thus need to be synonymised. Our analyses, which integrate the current naming rules, enhance the a-taxonomy of the genus and provide an effective identification tool based on DNA-barcodes. They illustrate the ability of DNA-barcodes, especially when type specimens are included, to pinpoint where a taxonomic revision is needed.

En 1983, W.F. PONDER publiait une révision mondiale de la famille des Xenophoridae. Dans ce même ouvrage, iI décrivait une nouvelle espece, Xenophora granulosa recoItée par Ie N/O "Vauban" dans Ie sud de la Nouvelle-Calédonie. Jusqu'à présent, quatre espèces du genre Xenophora étaient signalées de Nouvelle-Calédonie : - Xenophora (Xenophora) solarioides solarioides (Reeve, 1845) - Xenophora (Stellaria) lamberti Souverbie, 1873- Xenophora (Xenophora) cerea (Reeve, 1845) var. torrida - Xenophora (Xenophora) granulosa Ponder, 1983. En 1984, I'ORSTOM (*) débutait un programme de cartographie des peuplements benthiques de la Nouvelle Calédonie qui permettait d'échantillonner systématiquement la macrofaune et d'améliorer ainsi les connaissances faunistiques. Parmi les nombreux groupes zoologiques récoItés a la drague Charcot, les Mollusques representent I'un des plus important aussi bien en quantité qu'en diversité spécifique. Dans les récoItes réalisées dans Ie lagon Sud Ouest entre Teremba et I'Ile des Pins, nous avons rencontré cinq espèces de la famille des Xenophoridae, I'une d'elles (X. konoi) n'était pas signalée dans nos eaux et surtout nous avons recoIté de nombreux spécimens vivants de X. lamberti jusqu'alors connue de deux exemplaires et considerée comme fossile !

From the 26th of October to the lSt of November 1986, the R.V. "CORIOLIS' completed a dredging and trawling survey on the seamounts located on the Norfolk Ridge. The bathyal benthos was abundant and diversified. Several specimens of a Crinoid belonging to a family which was supposed to be extinct since the Jurassic were collected. At depths between 280 and 600 m these seamounts show flat tops the ichtyofauna of which is rich . Trawl hauls showed their fisheries potential as several high valued commercial species were caught e.g. Etelk comscans, Apsilus sp, , Pentaceros japonhi$, P. richardson< (armorhead) and Beryx sphmdens (alfonsin).

New Caledonia is an island situated in the South West Pacific on the edge of the Indo- Australian plate (fig. 1). The morphology of the sea-bed in this région is extremely complex and very varied structures occur. Thus the principal island of New Caledonia (The Mainland, or ' Grande-Terre '), and adjacent islands (the Isle of Pines and the Belep Islands) are an emerged portion of the Norfolk Ridge, a geosyncline dating from the Mesozoic, which extends to New Zealand.

The CHALCAL I cruise on board of the RV Coriolisi the Chesterfield Island region (19°-22°S and 157°-160°E) has allowed the collection of many fish species. We present here two detailed lists of these fishes. The first list includes 75 lagoonal species, caught between 60 and 90 m, 26 species of which are mentioned for the first time in this region. The second list includes 73 species of the bathyal zone (200-400) 35 of which are also new to this region. Biogeographical remarks allow to show affinities between the fish populations of this archipelago and those from nearby zones such as New Caledonia and Australia, but also those from tropical Japan.

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

The 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.

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

A new pineapple fish is described based on 26 type and 80 non-type specimens collected from Taiwan, Vanuatu, the Solomon Islands, and Queensland, Australia. This new species is sympatric with and similar to Monocentris japonica but can be distinguished from the latter in having only 6 or 7 scales on the third scale row below the lateral line; excisura notched and a small pseudo-excisura present on the sagittal otolith; consistently greater head depth, body depth, postorbital length, dorsal-fin–pelvic-fin length, and dorsal-fin–pectoral-fin length in proportion to standard length. A detailed description and designation of neotype are provided for M. japonica. DNA barcoding analysis supports the distinction of the new species with an estimated average COI gene divergence of 3.6 % from M. japonica.

Four new species of urolophid stingarees are described from the Coral Sea (South-West Pacific): Urolophus deforgesi sp. nov. and U. papilio sp. nov. from the continental slope of the Chesterfield Islands; U. neocaledoniensis sp. nov. is more widely distributed on the slopes of the Chesterfield Islands and New Caledonia and along the northern part of the Norfolk Ridge; U. piperatus sp. nov. is restricted to the coast of northern Queensland (Australia). The holotype and only known specimen of a rare and unusual stingaree, U. annatus Val. in Muller & Henle, 1841 from New Ireland (Bismark Archipelago), is redescribed and it could represent a new genus. The new species are mainly distinguished by a combination of the following characters: disc shape (particularly its width), dorsal fin (present or absent), interorbital distance (narrow or broad), tail length (short or elongated), coloration (plain or with spots), and oral papillae, vertebrae and pectoral-fin radial counts. A key for the urolophids of the Coral Sea is provided.

In this second study of MUSORSTOM Hexactinellida from New Caledonia, the Loyalty Islands, Wallis and Futuna Islands, and some seamounts from the South Pacific, 31 species (22 new) of Lyssacinosida, and a new subspecies of Caulophacus lotifolium Ijima, are described. New members of the formerly monotypic lyssacinosid genera Saccocalyx, Dictyaulus, Dictyocalyx, Neocaledoniella and Hyalostylus are described, and Neocaledoniella is introduced as a replacement name for the Caledoniella Tabachnick & Lévi in Tabachnick 2002, which is preoccupied.

A new species of parthenopid crab, Pseudolambrus guinotae n. sp., is described. The single male specimen, which was collected from New Caledonia, most closely resembles Pseudolambrus planus (Rathbun, 1911) but can be easily differentiated from the latter by possessing a much longer rostrum.

The genus Nemocardium Meek, 1876, is traditionally considered a relict of the past. Morphometric and morphological analyses reveal that the well-known species N. bechei (Reeve, 1847) is in need of taxonomic reconsideration. In this paper, five species are recognized, three of which are new to science: N. bechei from Taiwan, Philippines and Indonesia; N. probatum (Iredale, 1927) from northern Australia; N. australojaponicum spec. nov. From southern Japan and Korea; N. enigmaticum spec. nov. From the SouthWest Pacific and N. fulvum spec. nov. from Mozambique, Madagascar, Seychelles, India, Philippines and Vanuatu. All but the last species seem to occur perfectly parapatrically. With N. fulvum spec. nov., which is not confined to the Central Indo-Pacific but covers large parts of the Indian Ocean as well, the longitudinal range of Nemocardium is much wider than hitherto thought. A substitute lectotype is designated for Cardium bechei Reeve, 1847, and the New Zealand genus Varicardium Marwick, 1944, is synonymized with Nemocardium.

For the goatfish genus Upeneus Cuvier 1829 (Mullidae), a new taxonomic species group called the “margarethae group” is established which can be distinguished from the six species of the most similar “tragula group” by a combination of the following characteristics: absence of dark pigmentation in the area of the first dorsal-fin tip, 21–25 total gill rakers and 28–30 lateral-line scales. Initially, three recently-described species have been included in the margarethae group: Upeneus margarethae Uiblein & Heemstra, 2010, known from the Indian Ocean including the Red Sea and from the Arafura Sea (W Pacific), U. mouthami Randall & Kulbicki, 2006, from New Caledonia and Vanuatu (W Pacific), and U. randalli Uiblein & Heemstra, 2011, from the Arabian/Persian Gulf and the inner Gulf of Oman (NW Indian Ocean). The present taxonomic review of the margarethae group analyses a large data set of 41 morphometric, 10 meristic and many colour characters obtained from 279 preserved goatfish specimens and 166 fresh-colour photos (plus a fresh-colour drawing). For the nominal species of the group, U. margarethae, a redescription of the colour patterns is provided and new records for Myanmar, Andaman Sea (NE Indian Ocean) and the Gulf of Carpentaria, N Australia (W Pacific), are reported. Three new species are described: U. caudofasciatus n. sp. from the area of the Great Barrier Reef to Torres Strait off NE Australia (Coral Sea, W Pacific), U. gubal n. sp. from the S Gulf of Suez (Northern Red Sea), and U. heterospinus n. sp. from S Indonesia to Singapore, the Gulf of Thailand, Vietnam, Philippines, China, Taiwan and Japan (W Pacific). A comprehensive alpha-taxonomic approach is adopted, considering population differences as well as intraspecific sizerelated variation in morphology and colour patterns by splitting the data set into two size classes, adults (≥ 65 mm SL) and smaller subadults. Inter- and intraspecific comparisons include statistical analyses for species and population with sufficiently large samples sizes (n ≥ 20). Colour-pattern characterization and analysis are based on photos of recently collected and deceased fish (partly associated with voucher specimens), photos obtained from active or resting fishes in situ or in a tank, and inspection of pigmentation patterns retained in preserved specimens. Species differences are elaborated under consideration of distribution patterns and the characteristics found in the closest-most population of widely distributed species such as U. margarethae, resulting in clear and consistent distinction among the six species in single or in a combination of several characteristics. Comparisons among size classes revealed species-specific patterns in morphometric, meristic and colour changes with increasing size. One species, U. heterospinus n. sp., has seven or eight spines in the dorsal fin which occur in balanced ratio across populations. This is a unique characteristic for Upeneus species which usually have either seven or eight dorsal-fin spines, respectively. The best distinction of Upeneus heterospinus n. sp. from all other congeners is reached by combined examination of dorsal-fin spines with several other characters such as barbel colour, presence of a mid-lateral body stripe, pigmentation patterns (partly retained also in preserved fish), gillraker and pectoral-fin ray numbers, and body-shape variables. The high degree of overall morphological differentation among the three most common species U. caudofasciatus n. sp., U. heterospinus n. sp. and U. margarethae, as revealed by the statistical comparisons, strongly contrasts with a still signficant, but much lower degree of differentiation among populations. The diagnostic characteristics of the margarethae group are updated and the importance to use the results of this taxonomic review in ongoing fisheries-related and ecological research is emphasized. Requirements for future taxonomic research featuring the stunning diversity of the goatfish genus Upeneus are also discussed.

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.

This paper presents the first part of a study of large collections of Hydroida (Cnidaria : Hydrozoa) in the Museum national d'Histoire naturelle, Paris, originating from various expeditions in the Philippines, the eastern part of the Malay Archipelago, the Chesterfield Islands, New Caledonia and the Loyalty Islands. In this first part, genera of the family Sertulariidae Lamouroux, 1812, are reviewed, including new species of the genera Abietinaria Kirchenpauer, 1884 (1 new species), Dictyocladium Allman, 1888 (1 new species), Gonaxia nov. Gen. (20 new species and a new variety), SertularellaGray, 1848 (8 new species and a new subspecies), Symplectoscyphus Marktanner-Turneretscher, 1890 (6 new speciesand a new subspecies), and Thyroscyphus Allman, 1877 (1 new species). In addition to other, already known species from those genera, species of Caminothujaria Von Campenhausen, 1896, Cnidoscyphus Splettstosser, 1929, Dynamena Lamouroux, 1812, Geminella Billard, 1925, Hydrallmania Hincks, 1868, and Idiellana Cotton & Godfrey, 1942, are recorded. Many of the records are considerable range extensions or constitute new records for the Chesterfield Islands, New Caledonia and Loyalty Islands regions. Additional species and genera will be treated in a second part. Noteworthy is the occurrence of the curious new genus Gonaxia with many new species from the New Caledonia area, producing its gonothecae in intimate contact with the axis and its secondary tubules. Remarkable also is the occurrence of two northern Atlantic shallow water hydroids, Hydrallmania falcata (Linnaeus, 1758) and Diphasia attenuata (Hincks, 1861), the latter to be fully described in the sequel to this report, from deep water of the New Caledonia region. In zoogeographic context, the present study reveals a considerable degree of endemism in the deeper water hydroid fauna of the seas bordering New Caledonia and the Loyalty Islands, a phenomenon also observed amongst other groups of marine animals. Further zoogeographic comments will be postponed until a larger part of this highly interesting collection has been fully studied.

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 cardiids of the subfamily Trachycardiinae Stewatt, 1930 (sensu Keen, 1969, genus Papyridea excluded), are reviewed, with special attention given to the geneta Trachycardium, Acrosterigma, and Vasticardium. No change is proposed here to the relatively well-defined taxonomy of Trachycardium, consideted to be exclusively American, with six subgenera, nor to the American Acrosterigma. In contrast, the generic taxonomy of the Indo-Pacific Trachycardiinae, quasi-randomly distributed by authors among the three genera cited above, was not clear and is reevaluated. All of the species are regrouped here into two genera Vasticardium and Acrosterigma which receive clear and usable definitions. The American genus Trachycardium differs widely from them in both hinge and rib morphology. The two genera Vasticardium and Acrosterigma are distinguished mainly by rib motphology. These three genera are now grouped in the subfamily Cardiinae. In several previous articles, I have analyzed in detail the genus Vasticardium, including fifteen Recent species. The results are summarized here. The genus Acrosterigma is represented in America by several fossil species and two Recent species; in the Indo-Pacific, where no general study has previously been undettaken, it is represented by several fossil species (one new) and twenty-five Recent species, of which nine are new; these species are divided into six species-groups. Neotypes ate proposed for Cardium magnum Linné, 1758 and Cardium biradiatum Bruguière, 1789 and lectotypes for Cardium laevigatum Linné, 1758, Cardium serratum Linné, 1758, and Cardium marmoreum Lamarck, 1819.

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.

The bothid flounder family Bothidae contains 20 genus and 166 species. Most of the known species have wide distributions, others are restricted to specific zones and depth ranges. Fourteen bothid specimens captured near Vanuatu Archipelago were confirmed to be Parabothus taiwanensis (Pleuronectiformes; Bothidae), a rare species described before from only five specimens from the coasts of Taiwan and recorded only from the East China Sea (Amaoka and Shen, 1993; Yamada et al., 2007). The present note provides a description of these specimens with considerable range extension for this species and a new diagnostic character.

An analysis of lateral line system (LLS) morphology in 304 species (39% of those presently known) from 121 (92%) genera belonging to all 14 families of Pleuronectiformes is presented. The main feature of the LLS of flatfishes is bilateral asymmetry in the course of the cranial lateral line canals, but also in the reduction of canals or portions of canals, which occurs independently on the eyed and blind sides. The number of reductions is used to define two patterns for comparative analysis. A complete pattern is defined by the presence of all main canals, connected with each other, and the canaliculi that end in pores are usually highly branched. The reduced pattern is defined by the presence of more than two reductions. Each family is characterized by the occurrence of a complete pattern, a reduced pattern or both patterns. The combination of reductions varies considerably and characterizes taxa at the generic level. A reduced pattern appears independently several times and has a complex evolutionary history with reversals to a complete pattern. This study has shown that LLS characters are very informative for phylogeny and taxonomy and should be an important component of the description and revision of pleuronectiform taxa and their relationships.

Before talking about a largely underestimated and poorly known, yet so beautiful family of Gastropoda, there is an issue which I must attract your attention to. While gathering the necessary information, shells and literature, I often wondered why people still call some of the Tonnidae by the wrong name, despite the sometimes meticulous research done by scientists in the past. Is it because of the often controversial information in the available publications? Is it for lack of decent information? This issue became clear to me when I was looking into the most recent publications on Eudolium such as Piani (1977), Marshall (1992) and Bouchet & Waren (1993). All concluded that what is usually sold as Eudolium pyriforme is in fact Monterosato 's true Eudolium crosseanum. I must say I was a bit shocked to read those papers and see some photographs of the type material. Why were erroneous names still used ifproofwas there, clearly and undoubtedly, to the contrary? It took me a few weeks and a few discussions with Dr Philippe Bouchet and Dr Alan Beu to figure it out, but in the end, the answer is simple: In scientific terms, proof is given by photography and description, and maybe by discussion, but not in such words or language that they are understandable to the untrained reader. Also, such research is often documented in broader publications (e.g. Bouchet & Waren, 1993; Beu, 2005) that don't attract the attention of the advanced amateur or naturalist straight away, and are wrongfully neglected. These works are seldom offered commercially, and thus unjustly remain unknown to the wider public. It is in this respect that works such as the Concho logical Iconography, often written by advanced naturalists, have their true value and Guido Poppe, Klaus Groh and Yves Terryn must be commended for an initiative such as this is an excellent medium to bring science and amateur collecting closer together in an attempt to cover the gap between the two. It is my ambition to give a synoptical overview ofthe existing (described) species, based on my collection of well over 1000 specimens and an ever-increasing library of historical as well as recent publications. Ten years of collecting and studying shells and publications have resulted in what is to follow. I have listed the most important synonyms for each species in order to clarify some of the dubious issues, but the lists are not exhaustive. Although I have many of the old publications through digital photography, I'm sure that there are still many more out there. And even if I was to spend another month in the libraries of, e.g. the BM(NH) or the MNHN, there will still be publications "hidden" somewhere. I mainly concentrate my research on Recent material, whilst a lot has been described in the fossil area as well. For example: recently, Dr Alan Beu discovered that there is an earlier name for what we all know as Eudolium pyriforme (G. B. Sowerby III, 1914), namely Eudolium javanum (Martin, 1879), originally described as the fossil Cassidariajavana from the late Miocene oflndonesia. While researching this, he also discovered names such as Dolhun hochstetteri Martin, 1879 (= Tonna allium (Dillwyn, 1817)) just to give one example. Another issue is interpretation. Many have interpreted, e.g. Adanson's "Le Minjac" in different ways. For one author, it is T. marginata (Philippi, 1845), for another author T. tessellata (Lamarck, 1816). March (1852) even lists it as a full species, D. minjac. In order to clarify such matters, I have tried to compare specimens with type material. This publication should be a solid basis for any future researcher in this family and I do hope you will all find the necessary answers to your basic tun-related questions to start that collection you always wanted to start.
