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.

Based primarily on samples collected during French expeditions to New Caledonia and nearby regions, two new species of the sand crab family Albuneidae Stimpson, 1858 are described from the tropical Indo-West Pacific Ocean: Albunea holthuisi, from Tanzania, Madagascar and Indonesia, and Austrolepidopa caledonia, from New-Caledonia. Twi closely related, and often synonymizes species of Albunea: A. microps Miers, 1878 and A. elioti Benedict, 1904 are found to be distinct. Several important diagnostic morphological features, not previously described in the Albueidae, are discussed. In addition, we provide diagnoses for three Indo-West species of mole crabs in the family Hippidae Latreille, 1825, including the very similar Hippa pacifica Dana, 1852 and H. celaeno (de Man, 1986). An annotated list of the 37 species of Hippoidea reported from the Indo-West Pacific region is provided, along with a diagnostic key to these species.

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

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

Two new genera and four new species of Cirolanidae are reported from deep water (c. 440-2,050 m) off New Caledonia. These are Scutulana pezata, gen. nov., sp. nov., Sintorolana atrox gen. nov., sp. nov., Metacirolana neocaledonica sp. nov. and Politolana crosnieri sp. nov. Scutulana is distinguished by the unique pleonal morphology which has pleonites 4 and 5 laterally reduced but not overlapped by pleonite 3, morphology of the frontal lamina, by several mouthpart characters and by pereopod 1 having a setal brush on the dactylus. Sintorolana is closely related to Natatolana, and is distinguished from that genus and the other cirolanid genera by the expanded propodus of the anterior pereopods which are also heavily armed with spines and the elongate haptorial dactylus which extends to the merus. Metacirolana neocaledonica is closely allied to M. fornicata Mezhov, 1981, from which it is distinguished by the ornamentation of the pleotelson. These two species are separated from all others in the genus by the frontal lamina having an acute anteromedial point. Politolana crosnieri sp. Nov., the second record of the genus from beyond Atlantic waters, differs from other species of the genus in having a longer uropodal exopod, a pentagonal frontal lamina, and in the proportions of the antennule peduncle articles.

Verrucomorpha from deep sea collections made by several French cruises to New Caledonia, Loyalty Ridge, Vanuatu, Wallis Island and Futuna Islands, Comoro Islands, and by the French-Indonesian cruise KARUBAR in Indonesian waters, over the period 1985-1994, are investigated. Fourteen species of verrucid are described, including four new species. Verruca jago, Altiverruca jonesae, Brochiverruca crosnieri and Metaverruca maclaughlinae', the bathymetric and geographic ranges of verrucid taxa are extended, and it is confirmed that this is one of the most diverse verrucomorph faunas known. The stams of both Verruca and Metaverruca is considered, and a revised key to genera of the Verrucidae is given.

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

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

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

Crustacea Mysidacea : The Lophogastrida from Indonesia, New Caledonia and Wallis and Futuna Islands. A large series of samples dredged during different cruises in the tropical western Pacific have made it possible to draw up or complete the species inventories of various regions. Thirteen species, including two new to science, were found in Indonesia (KARUBAR and ESTASE 2 cruises): Gnathophausia ingens, G. longispina, G. elegans, G. fagei sp. Nov., G. zoea, G. gracilis, Lophogaster inermis sp. Nov., L. manilae, L. rotundatus, Paralophogaster glaber, P. philippinensis, P. boucheti and Eucopia sculpticauda. Only three species were found at Wallis and Futuna Islands (cruise MUSORSTOM 7) : G. longispina, L. manilae and L. neocaledonensis. Moreover, of the 4 species identified from New Caledonia, one - Lophogaster intermedins - is a new record, bringing the total number of species known from this area to 10. From all the results published since 1981, it can be seen that 9 of the 21 lophogastrid species identified were new to science, and that the species diversity is greatest in the Philippines and Indonesia (18 species), decreasing in New Caledonia (10), and is lowest at Wallis and Futuna (3). Finally, remarks are made on the diagnostic features of each species to be retained in order to facilitate their identification.

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.

The KARUBAR cruise in 1991 collected a number of deep-sea lobster specimens from Indonesia. The material is found to contain five species of palinurids, five species of scyllarids and 11 species of nephropids. Although no new species were found, the KARUBAR material extends the known distributions for many species, such as Linuparus trigonus (von Siebold, 1824), Palinustus unicornutus Berry, 1979, lbacus pubescens Holthuis, 1960, I. novemdentatus Gibbes, 1850, Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993,N. serrata Macpherson, 1993, N. stewarti Wood-Mason, 1872, N. sulcata Macpherson, 1990, and Metanephrops australiensis (Bruce, 1966). The most interesting finding is a complete specimen of Metanephrops arafurensis (de Man, 1905), which was previously known only from a mutilated type. Together with the additional knowledge gained of the characteristics of the other Metanephrops species, their relationships are discussed and a revised key to the species of this genus is provided.

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.

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

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

Heterocarpus tenuidentatus n. sp. is described from an ovigerous female collected off the Solomon Islands at a depth of between 814 and 980 meters. It is distinguished by a branchiostegal carina that extends along two thirds of the carapace, this being the only long, sharp carina on the lateral part of the carapace. It is also characterized by having the rostrum scarcely longer than half the length of the carapace, the small size of the upper rostral and postrostral teeth, the proportionally wide blade of the scaphocerite, and by being larger in size than any other Heterocarpus species.

Four deep-sea fishing expeditions conducted in the Indian ocean allowed to catch 31 species of penaeid shrimps. None of them is new but several of them were known only in geographic areas remote from the Indian ocean and they were often represented by a very small number of specimens which somethimes belonged only to one sex. Therefore, additional descriptions are given and they are based on a rather abundant illustration. Moreover, a few synonymies could be established by reexamination of various types.

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

During the CORINDON II and IV expeditions, the former in the Makassar Strait and the latter in Piru Bay and Ambon Bay, Molluccas, 47 species of penaeoid shrimps were collected. They include 2 species belonging to the Benthesicymidae, 5 to the Aristeidae, 19 to the Solenoceridae, 2 to the Sicyoniidae and 19 to the Penaeidae. The twenty eight species of the first four families are considered in this study; the Penaeidae will be presented in a separate publication. Most of the species treated in this work occur in deep water, with only a few samples taken in shallow water. Two species Cryptopenaeus clevai and Solenocera moosai are new ; eight others have not been recorded previously in the waters of Indonesia. Several specimens of Solenrocera annectens (Wood Mason, 1891) have been collected; this species has not been reported since its description and additional figures, particularly of genitalia, are included in this paper. One species of the genus Pseudarktew and one of the genus Solenocem both probably new, are recorded but not named as only a single specimen of each was collected. In addition to the description of Soleizoeera moosai, the original drawings of two closely related, but little known species, S. fuxoni De Man, 1907 and S. spiiiajugo Hall, 1961, are published. The bibliography is restricted to literature on Indonesian material. For each species, one or two references, each with comprehensive bibliographies, are provided. For station lists and expedition details, see Moosa.

Trap fishing in French Polynesia, at Mururoa (Tuamotu Archipelago), Tubuai (Austral Islands), and Tahiti obtained twelve species of shrimps of the family Pandalidae, only three of which had been reported previously from the region. Four are Heterocarpus and eight Plesionika. Of the latter, two, P. chacei and P. carsini, are new to Science.

The numerous samples collected during the MUSORSTOM I, II and III expéditions in the Philippines to which were added those of the CORINDON II and IV expéditions in Indonesia, those of the « Vauban » made from 1970 to 1974 around Madagascar, as well as various others, particularly collected in the Red Sea, Australia and New Caledonia, have permitted a reexamination of the Indo- West-Pacific deep-sea Metapenaeopsis. Ten species, of which three, M. liui, M. angusta and M. erythraea, are new, and one subspecies, M. provocatoria longirostris, also new, are recognized. A key to the species and subspecies, as well as illustrations of each are included.

Collecting from 1971 to 1982 in the South Western Indian Ocean resulted in the collection of 3 I species of Oplophorid Shrimps. Four of them, Acanthephyra frontieri, Heterogenys monnioti, Systellaspis curvispina and S. guillei, are new to Science and six others had never been reported from the Western Indian Ocean. Moreover the synonymy of Acanthephyra gracilipes Chace, 1940, with A. tenuipes Bate, 1888, is proposed and Notostomus rnurrayi Bate, 1888, which had never been reported since its description from a single specimen from the South Atlantic is discussed and illustrated. Finally, the variations of Systellaspis debilis (A. Milne Edwards, 1881) and S. pellucida (Filhol, 1885) are examined partly.

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

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

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

CORINDON 2, KARUBAR

During the MUSORSTOM 7 cruise, carried out in the economic zone of the Wallis and Futuna Islands and mainly devoted to the deepwater fauna, 26 species of peneid shrirnps belonging to the families Benthesicymidae, Aristaeidae and Penaeidae were collected. Only five of these had previously been recorded from the region (more exactly from the nearby Fiji Islands) and most of the species have had their known distribution ranges considerably extendOO.

MUSORSTOM 7

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

La campagne franco-indonésienne KARUBAR, faite à bord du navire de recherche indonésien "Baruna Jaya I", s'est déroulée dans l'est de l'indonésie, en mer de Banda et d'Arafura, au large des îles Kai et Tanimbar. Les prospections ont porté sur la faune bathyale. Quatre-vingt-onze dragages et chalutages, à des profondeurs comprises entre 200 et 1200m, ont été effectués.

A new species, Mursia longispina, previously confused with Mursia armata de Haan, 1837 and which is distinguished by the longest lateral spines of the carapace known in the genus Mursia, is described after specimens caught in New Caledonia.

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

A new species, Lebbeus laevirostris, is described from one specimen collected in the Makassar Strait, at a depth of 779-798 m. It can be distinguished fromall the other Lebbeus by its rostrum smooth on all its length and overreaching the eyes by almost half of its length.

CORINDON 2

A new genus and species, Eumanningia pliarthron, is described based on a specimen collected during the MUSORSTOM 7 cruise on the outer slope of Wallis Island, South-West Pacific, in depths of 890-915 m. Using available identification keys, this specimen would be placed in the genus Merhippolyte Bate, but as it differs from all species of this genus in several characters, of which the most obvious are: presence of three strong movable postrostral spines, posterior part of the third abdominal somite produced in an extremely large sharp tooth, left second pereiopod very long and with merus and carpus subdived into an unusually high number of articles, a new genus is created.

MUSORSTOM 7

The material examined for this note was obtained mostly by the MUSORSTOM 9 Expedition to the Marquesas, French Polynesia, in 1997. Collections were made from the intertidal zone to 260 m deep. Twenty-four species, of which four are new, are listed. The new species are: Portunus paralatibrachium n. sp. Which is very close to P. latibrachium (Rathbun, 1906) but which can be easily distinguished by the shapes of the abdomen and male first pleopod; Thalamita difficilis n. sp. Which belongs to the admete group and the auauensis-margaritimana subgroup, but can be distinguished from these two species by a series of characters (particularly the shape and positon of the frontal lobes and the male pleopods); Thalamita pseudopelsarti n. sp. Which is very close to T. pelsarti Montgomery, 1931, from which it is distinguished by a few but constant characters (shape and position of the frontal lobes, reduction in the size of the penultimate anterolateral tooth of the carapace, spinulation of the basal antennal article, etc.); Thalamita simillima n. sp. Which is very similar to T. pseudospinifera Crosnier, 1975 and from which it can be distinguished by an undivided first anterolateral tooth of the carapace, the spinulation and granulation of the chelipeds and the basal antennal article. A new subspecies, Thalamita auauensis dytica n. ssp., is erected for the specimens from the Indian Ocean previously identified as Thalamita auauensis Rathbun, 1906; they are distinguished by the ornamentation of the chelipeds and the form of the sixth abdominal segment. Two species known until now by their holotypes only have been rediscovered: Charybdis rathbuni Leene, 1938, described from Indonesia, and Thalamita multispinosa Stephenson & Rees, 1967, described from Hawaii. Thalamita seurati Nobili, 1906, known only by its holotype, unfortunately a female, is redescribed and illustrated. The possibility that T. wakensis Edmondson, 1925 is a synonym of the latter species is also discussed.

MUSORSTOM 9

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

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

During the French cruises conducted in the South-West Pacific during the last 20 years, two new Parapenaeus were found: Parapenaeus kensleyi n. sp., off New Caledonia, Vanuatu and the Fiji Islands; and Parapenaeus cayrei n. sp., off Tonga and the Chesterfield Islands. Amongst the Parapenaeus species provided with a branchiostegal spine on the anterior border of the carapace and extended by a rather long carina, P. kensleyi n. sp., with its long and sinuous rostrum, is related to P. australis Dall, 1957, P. lanceolatus (Bate, 1881) and P. perezfarfante Crosnier, 1986. Parapenaeus cayrei n. sp., with its short and straight rostrum, is related to P. fissurus (Bate, 1881), P. sextuberculatus Kubo, 1949 and P. ruberoculatus Hall, 1962. In both cases, the shape of the distal part of the ventrolateral lobe of the petasma in the males, the arrangement of the lateral bulbous portions and median tubercles, and the bulgings of the thelycum in the females allow the new species to be readily distinguished.

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

The species of the genus Trachypenaeopsis (Crustacea, Decapoda, Penaeidae). Morphological and molecular approaches. The genus Trachypenaeopsis Burkenroad, 1934 has been known in the Indo-West Pacific region by two species, T richtersii (Miers, 1884), described from Mauritius and recorded afterwards as far as Indonesia, Japan, and Hawaii, and T minicoyensis Thomas, 1972, known only from the Laccadive Is. The present work shows that T minicoyensis is a synonym of T richtersii, that identifications of material from China, Taiwan, and Hawaii are erroneous and that these specimens are not morphologically distinguishable from the Atlantic species, T mobilispinis (Rathbun, 1915), described from the West Indies. DNA analyses show that Pacific specimens other than T. richtersii belong to one species: genetic divergence is not higher than 2.2%, while the genetic distance between Pacific and Atlantic populations averages 3.6%. The absence of morphological differences between these two sets of populations indicates that the populations are becoming genetically different but cannot yet be considered separate species. The colour patterns of the Atlantic and Pacific specimens have not been determined so it is possible that these Populations could eventually be shown to represent separate sibling species.

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.

After a discussion of the valid publication date of the genus Intesius Guinot Richer de Forges, 1981 and of the structure of the male abdomen in this genus, new samples of L pilosus Guinot & Richer de Forges, 1981 are recorded from the Philippines and a new species, Intesius richeri n. sp., is described, based on a specimen from New Caledonian waters. The latter can be distinguished from the two other species of the genus by its more rectangular carapace, a less developed pilosity (particularly on the walking legs), and the second male pleopods ending in a very slender tubular part. Two other specimens, from Guam, are described under the name I lucius n. sp. They are very close to I. crosnieri Davie, 1998, known by a single specimen, but differ mainly by slightly longer, more slender and less pilose walking legs.

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

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

Echinolatus n. gen. is described for four species, E. bullatum (Balss, 1923), from the Juan Fernandez Islands off Chile, E. caledonicum (Moosa, 1996) from New Caledonia, E. proximum n. sp. from French Polynesia, and E. poorei n. sp. from the Great Australian Bight and southern Victoria. The first two species had been previously attributed to Nectocarcinus A. Milne Edwards, 1860. Echinolatus is characterised by a subhexagonal carapace, a quadrilobate front, at least the last pair of anterolateral carapace teeth, and usually others, bearing spinules or spiniform denticles on the anterior margins, the chelipeds having the carpus armed with a long pointed tooth at its anterointernal angle which also has a smaller strong tooth basally. E. bullatum is redescribed.

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

New specimens of the genus Eumunida Smith have been collected in the Indo-West Pacific, including new or poorly known species. The study of the material collected, together with the reexamination of types or published specimens of previously described species, demonstrated the need for a revision of the genus in the vast Indo-West Pacific area. The two groups of species recognised by authors since the work of GORDON (1930) are elevated in the present paper to subgeneric rank. The nominal subgenus Eumunida includes those species bearing a pair of well-developed spines on the anterior margin of the thoracic sternite 4 (group A of GORDON). The new subgenus Eumunidopsis, with Eumunida capillata de Saint Laurent & Macpherson, 1990, as type species, includes the species in which the anterior margin of this sternite is at most finely denticulated, most usually without any prominent spines. Four new species are established in the subgenus Eumunida: E. (Eumunida) treguieri sp. Nov., from French Polynesia, E. (Eumunida) multilineata sp. Nov., from the eastern coast of Australia, and E. (Eumunida) depressa and E. (Eumunida) macphersoni spp. Nov., both from Japan. Two new Indonesian species are described in the subgenus Eumunidopsis, E. (Eumunidopsis) ampliata and E. (Eumunidopsis) karubar spp. Nov. Apart from the description of new taxa, the present study includes a revised list of all known species from the Indo- West Pacific area, with an identification key, in French and English, along with references, types, remarks on the affinities and distribution. Whenever it has seemed useful, new diagnoses and illustrations of poorly known species are provided for each taxon. Two species have been collected in French Polynesia, where the genus had never before been found. E. (Eumunida) treguieri sp. Nov. Is a large species, close to E. (Eumunida) similior Baba, 1990, from Madagascar and to another new species from Japan. The second Polynesian species is E. (Eumunida) keijii de Saint Laurent & Macpherson, 1990, previously known only from New Caledonian waters. The Franco-Indonesian cruise KARUBAR, in 1992, has provided a few Eumunida. This material includes three specimens of E. (Eumunidopsis) smithii Henderson, 1885, about 20 individuals of a closely-allied species, E. (Eumunidopsis) karubar sp. Nov., a very small specimen of E. (Eumunidopsis) laevimana Gordon, 1930, never found since its original description, and one young male, provisionally identified as E. (Eumunida) pacifica Gordon, 1930. The taxonomic problems centered around Eumunida smithii, already discussed in DE SAINT LAURENT & MACPHERSON (1990a), have been solved ; the new KARUBAR material identified with it allows a better definition of the species and leads to the proposal of the synonymy of Eumunida propior Baba, 1988 with HENDERSON'S species. The "Siboga" specimens identified as E. balssi by VAN DAM (1933) are conspecific with it, while the material identified by GORDON (1930) and VAN DAM (1933) as E. smithii Henderson represents the same new taxon, herein described as E. (Eumunidopsis) ampliata sp. Nov. The small male from the "Albatross" dredgings cited in BABA (1988) belongs to another species very close to, if not identical with, E. (Eumunidopsis) capillata de Saint Laurent & Macpherson, 1990. The KARUBAR collections also include two dozen individuals of another new species, E. (Eumunidopsis) karubar sp. Nov., very close to E. (Eumunidopsis) parva de Saint Laurent & Macpherson, 1990, and E. (Eumunidopsis) smithii. These three species form a small unit of related taxa, without a pad on the propodus of the chelipeds, and in which the males have vestigial pleopods on abdominal segments 3 to 5, absent in all other Eumunida. Examination of three Japanese specimens of Eumunida cited by MIYAKE (1982: 144, pi. 48), and BABA (1986: 287, fig. 116) under the names E. fumambulus and E. pacifica, respectively proved to belong to neither species: they represent two different, new species, which are here described as E. depressa and E. macphersoni spp. Nov. The first is close to the new Polynesian species E. treguieri, the second to E. pacifica and E. keijii. The geographical ranges of several species are extended: E. (Eumunida) keijii de Saint Laurent & Macpherson, 1990, described from New Caledonian waters, has now been found in French Polynesia and off Wallis Islands in the South Eastern Pacific. Specimens attributed to E. (Eumunida) capillata, described by the same authors from New Caledonia, have been collected in Indonesia during the French Indonesian cruise KARUBAR; the "Albatross" specimen from the South of Taiwan, refered to E. smithii by BABA (1988), is also here attributed to E. capillata. Three small Eumunida (Eumunidopsis) from the Marshall Islands (Bikini), provided by the National Museum of Natural History, Washington, are identified as E. (Eumunida) minor de Saint Laurent & Macpherson, 1990, previously known only from New Caledonia and Madagascar.Some characters, used to differentiate the species, can vary according to the size and sex of the specimens. The striae of the carapace and abdominal tergites, the spinulation of the chelipeds, and the development of the ventral pad on their palm, for example, are likely to differ noticeably from the juvenile to the adult stages. Moreover, autotomy of one of the chelipeds is not infrequent in the genus, and may lead to a dimorphism in size and/or ornamentation of the regenerated appendage. Despite our efforts, the species identification of Eumunida remains difficult, the more so when only isolated specimens are available. Some of our taxonomic conclusions may need to be re-appraised if and when further material is collected. It should also be noted that the colouration of fresh specimens is important and has proved useful in helping to distinguish species in this study.

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

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

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.

The polychelids are large, uncommon, primitive decapods that inhabit the depths of the world oceans down to 5000 m, between latitudes 50°N and 55°S. A study of major deep-sea collecdons led to a revision of the family. All genera and species are redescribed and extended synonymies given. Two new genera are established: Cardus, for Polycheles crucifer (Thomson, 1873) and Homeryon, for Polycheles asper Rathbun, 1906 and a new species, H. armarium. The genus Pentacheles Bate, 1878, is revived to include polychelids in which the epipod on third maxilliped is longer than the ischium: P. gibbus Alcock, 1894, P. laevis Bate, 1878, P. obscurus Bate, 1878, P. synderi (Rathbun, 1906) and P. validus A.

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

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

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

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

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

The study of many samples collected by MUSORSTOM cruises, deposited in the Muséum national d'Histoire naturelle, as well as the reexamination of types and published specimens reveal that Pasiphaea sivado (Risso, 1816) and the related species, P. propinqua de Man, 1916, P. japonica Omori, 1976, P. marisrubri Iwasaki, 1989 and P. nudipeda Burukovsky, 1993, belong to one group. All are characterized by a terminal spine on the sixth abdominal somite and a branchial reduction. However, P. nudipeda is entirely devoid of arthrobranchia, has unarmed first pereiopods and three pairs of spines on the posterior margin of telson and has to be separated; a new genus Alainopasipheae is proposed for it. The other species mentionned above, except P. marisrubi, bear three arthrobranchiae from the fourth to sixth thoracic somites. P. marisrubri and five new species found in the MUSORSTOM material and belonging in this group have four pleurobranchiae from the fourth to seventh thoracic somites. On the other hand, P. propinqua, P. japonica and P. sivado have one more, but rudimentary, pleurobranchia on the eight somite. A key for all these species is provided.

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

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

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

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

Twenty six species of brachiopods were dredged in the bathyal area surrounding New-Caledonia and the Chesterfield Islands, from 1985 to 1989, during the cmises BIOCAL, BIOGEOCAL, CALSUB, CHALCAL 2, MUSORSTOM 4, 5, 6, SMIB 1, 4, and VOLSMAR. That fauna shows a broad diversity, including 19 genera belonging to 14 families. A new genus {Kanakythyris) and four new species are described {K. pachyrhynchos, Stenosarina globosa, S. lata, Fallax neocaledonensis). Several species are strongly sulcate {Neorhynchia strebeli. Abyssothyris wyvillei, K. pachyrhynchos, Nipponithyris afra), a feature that is usually considered as typical of deep-sea brachiopods. Nevertheless, this feature also occurs in New-Caledonian species at lesser depths. Moreover, in several taxa, size differences between populations or species seem to be related to depth.

Parapagurid hermit crabs are reported for the first time from French Polynesia, based on a collection obtained during a deep-water trapping survey by the French government's Service Mixte de Contrôle Biologique des Armées. The collection contains nine species of the genus Sympagurus Smith, 1883, four of which are new, and one of Slrobopagurus Lemaitre, 1989. The material of the previously described species of Sympagurus found in French Polynesia is compared with types and supplemental specimens from other IndoPacific regions, and the species diagnosed in light of a recent re-evaluation of diagnostic characters in this genus. Based on examination of representative material of ail Sympagurus species from the world oceans, three informai groups are proposed for the species. Group 1, including nine species, is defined by the presence of a slender, curved epistomial spine; Group 2, including ten species, is defined by the presence of a vestigial pleurobranch on each side of the last thoracic somite; and a heterogenous Group 3, for the remaining 14 species and three subspecies, all of which lack a curved epistomial spine and vestigial pleurobranch on the last thoracic somite. A list of all known species of Sympagurus is presented, along with their geographic and bathymetric distributions.

During the French-Indonesian KARUBAR campaign, ten species and a megalopal stage of deep-water hermit crabs of the family Parapaguridae, were collected. Two of the species found in the collection are undescribed, Oncopagurus glebosus sp. nov., and Paragiopagurus insolitus sp. nov., and are characterized by several unusual or unique characters. One previously described species, Oncopagurus orientalis (de Saint Laurent, 1972), was found to be insufficiently defined. These three species are described or diagnosed, and illustrated. Another species, Parapagurus latimanus Henderson, 1888, is reported for the first time from Indonesia. Two megalopal stage specimens of a parapagurid species cannot be assigned with certainty based on current knowledge, to any species; they are also illustrated and discussed.

A review of the deep-water hermit crab species of the genus Parapagurus Smith, 1879 from the Indian and Pacific Oceans is presented based on abundant samples obtained during French expeditions to the New Caledonia region, and supplemented with extensive material deposited in various major museums and institutions throughout the world. A total of 14 species were found to occur in the Indian and Pacific Oceans. Of these seven are new, P. richeri sp. nov., P. furici sp. nov., P. stenorhinus sp. nov., P. saintlaurentae sp. nov., P. janetae sp. nov., P. foraminosus sp. nov., and P. woljfi sp. nov.; and three, P. abyssorum (Filhol, 1885), P. bouvieri Stebbing, 1910, and P. andreui Macpherson, 1984, include parts of the Atlantic Ocean in their distribution. The new species are fully described and illustrated; all previously known species are diagnosed or in the case of one obscurely defined species, P. holihuisi Lemaitre, 1989, redescribed. Information on morphological variations is included for the most abundant species, and a key to aid in the identification of all 14 species is given. Of the seven new species, P. richeri sp. nov. and P. furici sp. nov., were found in the New Caledonia region but are also distributed elsewhere in the Indo-Pacific; P. saintlaurentae sp. nov. and P. stenorhinus sp. nov., have been found exclusively in the Indian Ocean; and P. janetae sp. nov., P. foraminosus sp. nov., and P. wolffi sp. nov., exclusively in the eastern Pacific. As result of this study, the genus now contains 17 species, of which P. pilosimanus Smith, 1879, P. nudus (A. Milne-Edwards, 1891), and P. alaminos Lemaitre, 1986, are so far known only from the Atlantic Ocean. The bathymétrie distribution of all species in the genus is summarized.

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.

Three subfamilies are recognised : Asthelysinae new subfamily, Seguenziinae Verrill, and Guttulinae Goryachev. Two tribes are recognised in Seguenziinae. Fifty five seguenziids are newly recorded from off New Caledonia and the Loyalty Islands, of which 50 are new to science. These species are referable to 13 genera, including 2 new genera and Anxietas Iredale, which is transferred from Trochidae. Asthelys nitidula sp. Nov. is based on type material from Queensland. Jaw plates and lateromarginal radular plates are recorded for the first time in the family. Seguenziid species richness and western Pacific biogeography are briefly discussed.

This paper reports upon the snake eels collected by trawl during the 1985 MUSORSTOM 4 New Caledonia Expedition. The 14 specimens comprised five new ophichthid taxa which are described herein: Ophichthus exounis sp. nov. from 400-520 m (also from Fiji); O. genie sp. nov. from 430-500 m (also from Maldives); O. mystacinus sp. nov. from 450-580 m; Yirrkala insolitus sp. nov. from 59 m; and Rhinophichthus penicillatus gen. et sp. nov. from 435 m. The dorsal fin location of the new species of Yirrkala provides an expanded character state within the genus. Rhinophichthus differs from other generalized ophichthins in its very conical snout, and includes Ophichthys unicolor Regan from South Africa. The affinities of the new taxa are with Indo-west Pacific ophichthids, however the collections are too few to allow significant conclusions about the bathyal ophichthid fauna of the region.

The French-Indonesian 1991 campagne to the islands of Kai, Aru, and Tanimbar, part of the Maluku region of Indonesia, revealed an unexpected wealth of hermit crabs of the family Paguridae. Although only 295 specimens were collected in depths ranging from 85 to 1024 meters, an incredible 19 genera and 36 species are represented, of which seven genera and 26 species are described for the first time. Included are the monotypic Alainopaguroides gen. nov., Enneopagurus gen. nov., Enneophyllus gen. nov., lcelopagurus gen. nov., and Tarrasopagurus gen. nov., and their respective new species. The genus Michelopagurus, gen. nov., is established for "Pagurodes" limatu lus Henderson, 1888, and one additional new species, and the genus Pseudopagurus is created for "Pagurodes" piliferus Henderson, 1888, the last of the original trio of species initially assigned to the heterogeneous Pagurodes. A lectotype for Pagurodes inarmatus Henderson, 1888, the type species of the now monotypic Pagurodes, is also designated. The genus Turleania is proposed as a replacement name for Laurentia McLaughlin & Haig. Of the new genera, three are particularly noteworthy. Not only are Enneopagurus and Enneophyllus just the second and third genera of the Paguridae to be characterized, in part, by the absence of gills on the third maxillipeds, the latter genus is unique, at least for the present. !ts type species. E. spinirostris sp. nov., is the first pagurid known to have a weil developed epi-rostral spine. Alainopaguroides joins that very specialized group of genera distinguished by marked reduction in the abdomen, accompanied by total loss of male pleopods and reduction in the number of female pleopods. Two additional genera of this group, Solitariopagurus and Porcellanopagurus, are also represented in the KARUBAR collection, each by a new species. In addition to the new genera, new species are described in several of the less commonly reported genera, e.g., Catapaguroides, Decaphyllus, Catapagurus, and Tomopaguropsis. Although Pagurus is widely represented in the colder waters, particularly of the northern hemisphere, the discovery of three new species from the restricted geographic region of the KARUBAR campagne was unexpected. A third species has been added to, and extends the distributional range of, the recently described Bathypaguropsis from Australian and New Zealand waters. A new species described in Australeremus has provided continuity to the heretofore disjunct distribution of this genus. Only one genus, Pylopaguropsis, was represented entirely by known species.The KARUBAR collection is also significant for its number of highly evolved genera. Specifically, development of the male sexual tube(s) is uncommonly prevalent. In the 19 genera included in the collection, males of 13 develop a sexual tube on one or both coxae of the fifth pereopods, or nearly two-thirds of the total genera. All species are fully illustrated and detailed descriptions or diagnoses provided. Keys are provided for the regional genera and species, including those reported from the Maluku area, but not included in the KARUBAR collection.

The new genus, Diacanthurus, is proposed for a group of three Recent and one fossil species formeriy assigned to the heterogeneous genus Pagurus Fabricius. In addition to the transfer of Pagurus clifdenensis Hyden & Forest (fossil), P. spinulimanus (Miers), P. rubricatus (Henderson), and P. ophthalmicus (Ortmann), two new species, Diacanthurus ecphyma sp. nov. from New Caledonia and Western Australia, and D. richeri sp. nov. from New Caledonia are assigned to this new genus. Expanded diagnoses or descriptions and illustrations of all Recent species are provided.

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

We reported in an earlier paper the great species richness of the grenadier fauna (families Bathygadidae and Macrouridae) from recent bathyal trawl collections made mainly during MUSORSTOM cruises in the New Caledonian region. Here we add information from further samples to complement earlier taxonomic findings, and descriptions of 2 new species, together with comments on species, distribution and ecology. Thus a total of 2055 specimens from 221 samples examined representing 20 genera and 63 species were found to have closest similarity in composition with New South Wales, Western Australia and New Zealand. As expected, dissimilarity increased with distance from New Caledonia. Four genera dominated in species richness: Caelorinchus (17), Hymenocephalus (8), Nezumia (5) and Ventrifossa (6), comprising 2/3 of the total fauna. The generic make-up of the faunas closest to New Caledonia were most consistent with that region; propordons varied radically from there in the more distant regions invesdgated. Bathymetrically, the smaller trawls of the MUSORSTOM surveys collected grenadiers over a range of tows shallower than that reflected by the commercial gear used on the HALIPRO 2 cruise, with a generally smaller size of fish sampled. Co-occurrence of grenadier species within similar depth strata on the slope was remarkably high, with only two of the 63 species not represented, at least over part of their depth range, in the upper 1600 m. Species richness peaked at 37 in both the 700 and 800 tn strata, although it did not drop below 20 across the depth range 400-1100 m and reduced substantially only deeper than 1400 m.

Fifteen species of comatulid crinoids in eleven genera and four families collected in 180-800 m by the joint French-Indonesian KARUBAR Expedition to the Kai and Tanimbar Islands, Indonesia (October 1991), are described in detail. The specimens represent the most important collection of bathyal comatulids from the East Indies in the second half of the twentieth century. The material described herein comprises four species of Comasteridae, one Asterometridae, two Calometridae and eight Thalassometridae. One species of calometrid (Neometra xenocladia sp. nov.) is described as new. FiveTpecies are recorded for the first dme since they were originally collected. Four thalassometrids (Aglaometra valida, Oceanometra annandalei, Cosmiometra philippinensis and Stenometra cristata) together account for 75% of identified specimens, reflecting this family's importance to the outer shelf-upper bathyal comatulid fauna of the tropical Indo-Western Pacific. The substantial amount of material of several species, notably A. valida and O. annandalei, permits a better understanding of morphological variability than previously. Statistical analyses of several sipposedly diagnostic characteristics including aspects of calyx form and number of cirri, reveal substantial variation. We place several taxa in sinonymy as a result. SIM studies of different ossicles have been made for the first time for A. valida and O. annandalei. The preliminary results show that great morphological differences exist within the family. Three species (Stiremetra breviradia, Palaeocomatella hiwia and Cosmonuetra iole) are recorded from Indonesian waters for the first time. Moreover, most of the KARUBAR comatulids represent geographical and bathymetrical range extensions.

A survey of the bathyal and abyssal area around New Caledonia began in the South-West Pacific Ocean with some recent cruises of french research vessels. The ascidian fauna appears especially diverse, with 58 species of which 31 are new. The species described here belong to almost all genera known throughout the world showing deep-sea adaptations. The 5 main types of trophic adaptation defined for deep-sea tunicates are represented. Around New Caledonia the species having the most elaborate adaptations are more numerous than in the Antarctic, Atlantic or Indian Oceans. Some of the species may possibly be intermediates between shallow water and deep-sea genera. Some genera previously known by a small number of species are here very diverse, and provide the opportunity to discuss their affinities. This applies to the genera Pharyngodictyon (Aplousobranchia), Simla (Octacnemidae), Bathyoncus and Fungulus (Stolidobranchiata). A new interpretation of Corynascidia and Pterygascidia is proposed. With the discovery of 3 new species in New Caledonia, some evolutionary stages of the genus Molguloides (Molgulidae) may now be discussed in terms of branchial structure. A tabular key of the 13 species of this genus is presented. The bathymetric distribution is compared here and in other oceans. The species showing morphological adaptations to the deep-sea live at higher levels in the New Caledonia area than in other oceanic basins. However the presence of deep-sea forms in relatively high levels has been established in other tropical areas (Indonesia, Philippines, Comores). The higher temperature of the water at this depth in low latitudes may have less influence on the ascidian ecology than the seasonal variations occurring in temperate and cold areas at equivalent depths. The affinities of the New Caledonian deep-sea ascidians vary with the families and the kind of adaptations but they are most closely related to the antiboreal fauna of temperate and cold areas. There is no relationship with the shallow water fauna. For the Polyclinidae, with the greatest diversity, relations are established with New Zealand and the subantarctic areas. The deep-sea phlebobranchs are principally known from the southern hemisphere. New Caledonia has the largest number of Octacnemidae species wordwide. The Styelidae dominate in the deep Atlantic but are poorly represented here. The Pyuridae appear to have expanded from both Austral and Indomalayan areas. The majority of the deep-sea species of Molguloides live in the southern hemisphere and all the shallow-water species are Austral ; the genus is particularly diverse around New Caledonia.

Collectings by deep SCUBA dives have brought up 4 new species of Plurellidae, a family known by 2 Plurella species and one Microeastra. A new genus Plurascidia is also described, intermediate between the Plurellidae and the Ascidiidae families. All these new species are compared to the 3 Plurellidae already known and to a strange deep Ascidiidae, Fimbrora calsubia.

Six mid-depth octopuses of the Order Octopoda are reported from the Banda and Arafura Seas off Indonesia and northern Australia, based on material collected through the collaborative French-Indonesian KARuBAR cmise of 1991. Octopod material was collected through benthic trawls at 18 of 91 stations, at depths between 199 and 869 metres. Two new species are described here, Benthoctopus karubar sp. nov. and Octopus pyrum sp. nov. An additional species of the genus Octopus is reported as indeterminate but distinct from O. pyrum. The genus Pteroctopus is reported from IndoPacifie waters for the first time, based on female material collected through the KARuBAR cmise and linked with additional male material collected off New Caledonia and Vanuatu. Eledone palari is recorded as a northerly extension to the Australian distribution reported in the original description for this species. A single submature female of the pelagie octopod, Haliphron atlanticus (previously treated under the name Alloposus mollis), is also reported from the region. The depth distributions and phylogenetic affinities of this fauna are discussed.

Four species of Stegidotea Poore (S. pinnata Poore, S. longipes sp. nov., S. carinata sp. nov. and S. forcipes sp. nov.) are reported from deep water in the region of New Caledonia. The last of these is unusual in several respects having a complex seta on the palm of the fust three pereopods, subequal uropodal rami, a spike-like molar process and a habitus different from all other species of the genus. Symmius philippinensis sp. nov. is described from the Philippines, the third species in this north-western Pacific genus. The 14 species of Chaetiliidae known from the Western Pacific (Japan, Philippines, New Caledonia, Australia and New Zealand) are tabulated.

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 Musorstom 7 Cruise in the Walis and Futuna economic zone. Report and list of stations. The MUSORSTOM7 cruise took place from the 5th of May to the 4th of June 1992 in the Wallis and Futuna economic zone. The 142 dredgings ans trawlings were realized in the upper bathyal zone, on the slopes of Futuna, Alofi and Wallis Islands ans on the slopes of the numerous seamounts laying in this area. The deep sea fauna collected was quite poor but diverse. Some animals described formerly from New Caledonian's waters are now rediscovered on the Pacific plate (Sphinctozoa, Gymnocrinus, Amalda)

Sampling cruises of bathyal benthos in New Caledonia for the years 1993-94 (BATHUS 1-4, SMIB 8, HALIPRO 1). In 1992 and 1993, several oceanographic cruises (BATHUS 1-4) were carried out with the aim of improving the inventory of the benthic fauna of the outer slopes around New Caledonia. On the basis of these results, another cruise (HALIPRO 1) was devoted to the sampling of fishes on slopes suitable for trawling, down to depths of 1100 m. In addition, the SMIB (Substances Marines d'Intérêt Biologique) research program was continued, with a new cruise - SMIB 8 - collecting deepwater invertebrates for experimentation. All of these cruises took place on board the R.V. "Alis" of the Nouméa Research Station (ORSTOM). The present paper gives an account of the fauna collected, the geomorphological characteristics of the zones explored, and an indication of particular studies on the material collected. The latter include population genetics (particularly of Brachiopoda and decapod Crustacea) and crustacean phylogeny. An appendix is provided, giving a list of stations sampled by the various cruises and their general characteristics.

The MUSORSTOM 9 cruise was carried out in the Marquesas Archipelago from 18 August to 11 September 1997. 168 samples by dredging and trawling were made in the upper-bathyal zone and in the circalittoral depths, on the slope ofthe islands and on the top of the Dumont d'Urville Seamount. A terrace with a gentle slope is surrounding each island. Deeper than 100 meters the slope is very steep with from time to time terraces between 400 and 600 meters deep. The benthic fauna of this remote archipelago isolated in the Central Pacific is remarkably poor in all the groups.

The BORDAU 1 cruise was carried out in the Fijian Archipelago from 22 February to 14 March 1999 on board of R.V. "Alis". A total of 118 samples were made by dredging and trawling in the upper bathyal zone and in the circalittoral depths of the islands and on the seamounts in the Lau Ridge. The upper part of the slope to 600 m consists of hard bottoms and deeper muddy bottoms with pumice. In some islands particularly isolated (Vanua Balavu, Yacata, Aiwa and Yagasa), the landsnails were sampled.

BORDAU 1

The MUSORSTOM 10 cruise, using the R.V. "Alis", was carried out in the Fijian Archipelago during 5-19 August 1998. A total of 82 samples were collected by dredging and trawling from the upper bathyal zone and in the circalittoral depths, on the outer reef slopes of Vitu Levu and from Bhgh Water. The bottom of Bligh Water is muddy and covered with pumice stones. Hard bottoms were sampled in the Beqa Channel. The invertebrate biodiversity of the benthic communities sampled is much lower than those sampled from the New Caledonian area, especially sessile epifaunal groups like sponges, stylasterine hydrocorals (Cnidaria, Stylasterina) and crinoids.

The CALSUB cruise took place in 1989 off the coast of New Caledonia. The diving saucer Cyana enabled the exploration of the bathyal environment from the edge of the coral platform down to a depth of 3000 m. In this paper an account is given of how the study was carried out, along with the material gathered during the course of the study which may be consulted (in particular the photographs and the videos). The various sectors explored, and the principal observations made are discussed. Apart from the wide diversity of ecological niches observed, what makes this sector of the Pacific Ocean original, is the existence of bathyal benthic communities rich in "living fossils", giving us an idea of the fauna which populated the Tethys Ocean during the Mesozoic. The use of the Cyana diving saucer allowed direct observation of the nature of the sea beds and the associated fauna, in particular of rocky slabs, and environments affected by deep currents, where fields of hydraulic bioclastic dunes develop along fault scarps covered with dense populations dominated by Echinoderms. We were able to establish the bathymetrical distribution of the bathyal populations.

Four new species, belonging to the subfamily Rissoininae (Neotaenioglossa: Truncatelloidea: Rissoidae), are described from deep water in the Nex Caledonian region: rissoina (Rissoina) boucheti sp. nov., R. longispira sp. nov., Zebina (Zebina) re sp. nov. And Z retusa sp. nov. An anatomical description of R. Boucheti is given.

Fourty-nine species of Pycnogonida (and six unidentifiable forms) are recorded from the continental slope (200-3740 m) in the Western Pacific off New Caledonia, the Loyalty and Chesterfield Islands, and in the Lau Basin ; only six samples originate from the continental shelf (40-73 m). Of these 49 species, not less than 33 (67 %) are new to Science. The new species belong to the genera Ascorhynchus (3 spp.), Ammothella (1 sp.), Heterofragilia (1 sp.), Cilunculus (4 spp.), Proboehmia gen. Nov. (1 sp.), Sericosura (1 sp.), Rhopalorhynchus (1 sp.), Colossendeis (1 sp.), Hedgpelhia (1 sp.), Austrodecus (5 spp., of which 4 attributed to a new subgenus, Tubidecus), Nymphon (4 spp.), Seguapallene (1 sp.), Parapallene (1 sp.), Pallenopsis s. str. (1 sp.), Pallenopsis (Bathypallenopsis) (1 sp.), Phoxichilidium (2 spp.). Anoplodactylus (1 sp.), and Pycnogonum (3 spp.). The richness in new species is explained by the fact that the bathyal zone around New Caledonia was unexplored so far for Pycnogonida.

Nineteen new species are described from the bathyal zone of the Arafura Sea at depths between 146 and 1084 m. The genus Lusitanops is recorded for the first time from the Indo-Pacific and Clinura vitrea sp. nov. is the first Recent representative of this hitherto Cenozoic fossil genus. Based on shell and radula morphology, the classification of Heteroturris in the Clathurellinae is confirmed. Including new species described here, there are now 92 turrid species recorded from Indonesia at depths greater than 200 m.

Euryplegma auriculare, previously known off the coast of New Zealand, has recently been collected from the vicinity of New Caledonia, Fiji, Wallis and Futuna Islands. The description of spicules, structure and speculation on the origin of this species as well as reinvestigation of the related genera, Tretopleura and Fieldingia, has led to revision of the family Aulocalycidae and modification of its diagnosis. The scope of the family has been restricted to five genera: Euryplegma. Aulocalyx, Rhabdodictyon, Ijimadictyon, and Leioplegma. A new taxon Aulocalycoida, with the same rank as the orders Hexactinosa, Lychniscosa, Lyssacinosa, has been proposed to receive the reorganized family. It is distinguished by an aulocalycoid framework. The order Hexactinosa is thus restricted to include all of its former families except for the family Aulocalycidae. Two genera previously included in the Aulocalycidae, Tretopleura and Fieldingia, are reassigned because of their lack of an aulocalycoid framework. Tretopleura is referred to the hexactinose family Euretidae without a clear closest relative. Fieldingia (sensu stricto), still pooriy known, is provisionally referred to the order Reticulosa, as incertae sedis, and possibly represents the only extant member of that group. It has some similarity to the family Stromatidiidae, but cannot be included in that taxon with the limited information now available. The position of Reticulosa in relation to the more well-known recent Hexactinellida taxa remains unclear.

Six species belonging in the family Cyclodorripidae were collected from the Vanuatu Archipelago, in 1994, during the MUSORSTOM 8 cruise. One of them, Tymolus daviei, is new and has been found too in New Caledonia; it constitutes the first record of the genus Tymolus in this area. The five other species, already known from other localities within the Indo-Pacific, are recorded for the first time from the Vanuatu Archipelago: Krangalangia spinosa (Zarenkov, 1970), known from Australia, New Caledonia, Chesterfield and Wallis and Futuna Islands; Krangalangia orstom Tavares, 1993, known from Loyauté and Wallis and Futuna Islands; Ketamia limatula Tavares, 1993, known from Indonesia; Phyllotymolinum crosnieri Tavares, 1993, known from New Caledonia; and Xeinostoma richeri Tavares, 1993, known from Chesterfield and Wallis and Futuna Islands.

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

Psammina zonaria sp. nov. is the first member of this genus described from bathyal depths of the West Pacific. It is characterized by strong compartmentalization of the interior space and strictly directional growth. It appears to live attached to hard substrates, with the sriff but fragile test sticking up in the near-bottom water layer.

The purpose of the BIOCAL, MUSORSTOM 4 and BIOGEOCAL océanographie cruises was to study the nature and the affinities of the deep-sea fauna of New Caledonia. This area has been until then poorly prospected and its echinoderm fauna is almost unknown. Among the Ophiuridae collected during these two cruises, a first group of 10 species is studied. Five of them are new for science : the subfamilial status of the genus Ophiophyllum Lyman and the affinities of the genera Anihophiura Fasmer and Aspidophiura Matsumoto are discussed. The species belonging to the genera Ophiophycis. Ophiopyrgus, Aspidophiura. Anthophiura. Ophiotypa and Perlophiura. Very small and showing a rudimentary external morphology, are considered as progenetic. These present collects show once more the frequency of these progenetic forms at bathyal and abyssal levels.

The deep-water Cancellariidae collected during the KARUBAR cruise near the Kai and Tanimbar Islands are represented by 20 species (9 new), only two of which were recorded earlier from the Arafura Sea. As many as 14 species (70% of the total) are represented by single specimens, and 17 (85%) have been collected at one station only: this points to a still more diverse cancellariid fauna. New species of Axelella, Perplicaria, and Solatia represent the first occurence of these genera in the Indo-West Pacific. Admete aethiopica Thiele, 1925, recently suspected to be a species of Turridae, is confirmed as a cancellariid.

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