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

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

The pontoniine shrimps collected by the second MUSORSTOM Expedition, 1980, to the Philippine Islands, are described. The collection includes eight species, only two of which were also captured by the first expedition. Of these, two represent new species of Periclimenes and Onycocaris and one a new genus, Plesiopontonia. A key for the identification of the twelve deep water (> 100 m) Indo-West Pacific species of Periclimenes is also provided.

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.

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.

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

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

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

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

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.

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

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

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

From bottom trawlings at 38 stations in Philippines waters during the MUSORSTOM cruise, this firsf list deals with 106 species of fishes. Among them three are new, Plectranthias foresti, Callanthias crosnieri and Chlorophtalmus brevirostris; many are rare and some are cited for the first time. The bathymetric distributions are revised or specified for most of the species.

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

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

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

The deep-sea Brachyura Majidae collected during the MUSORSTOM I and II cruises in the Philippines, completed by several other indo-pacific collections, are studied here : genera Platymaia, Cyrtomaia, Pleistacantha, Sphenocarcinus and Naxioides. A key is given for the genera Platymaia and Sphenocarcinus. Four new species are described : Platymaia rebierei, from New Hebrida ; Sphenocarcinus stuckiae and S. orbiculatus, both from New Caledonia, and S. bipartitus from Philippines.

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

This paper reports on Muricidae originating mostly from the continental slopes of South-East Asia, New Caledonia and S. French Polynesia. The genus Daphnellopsis Schepman, 1913 and Latiaxis sibogae Schepman, 1911 are transferred respectively from the Turridae and from the Coralliophilidae to the Muricidae ; Pterynotus cerinamarumai Kosuge, 1980 is synonymized with Chicoreus orchidiflorus (Shikama, 1973) and Siratus hirasei Shikama, 1973 with Chicoreus (Siratus) pliciferoides Kuroda, 1942. The following new species are described : Poirieria (Paziella) vaubanensis, Poirieria (Paziella) acerapex and Poirieria (Paziella) spinacutus (all from New Caledonia, 250-550 m), Trophon (Trophonopsis) minirotundus (New Caledonia, 250-350 m), Nipponotrophon regina (Philippines, 680-970 m), Typhis (Typhina) virginiae and Siphonochelus (Laevityphis) tillierae (New Caledonia, 250-430 m).

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

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

En dehors des PORTUNIDAE, étudiés séparément, plus de 155 espèces de Brachyoures récoltées aux Philippines par l'expédition MUSORSTOM ont été l'objet d'une identification préliminaire. Des espèces rares, uniquement signalées de l'Océan Indien ou des eaux japonaises, sont mêlées à d'autres connues des Philippines seulement. Plusieurs espèces n'avaient pas été retrouvées depuis leur description originale. Trois formes de XANTHIDAE sont nouvelles : PARAMEDAEUS PLANIFRONS GLOBUSUS ssp. nov., CROSNIERIUS CARINATUS gen. nov., sp. nov., NEOXANTHIAS MICHELAE sp. nov. Parmi les espèces non identifiées certaines sont aussi probablement nouvelles ; c'est le cas notamment d'une espèce de PISIDAE et d'une espèce de RETROPLUMIDAE, lesquels sont particulièrement bien représentés dans la collection (quatre espèces)

After a more detailed investigation of its skeletal anatomy, the Japanese Bathyraja tobitukai (Hiyama, 1940) is removed from its genus and is considered as a species of Notoraja Ishiyama, 1958. The latter taxon is elevated to generic rank from its original status as a subgenus of Bathyraja Ishiyama, 1958. A single early adolescent specimen, obtained in 1980 during the MUSORSTOM 2 expedition from deep water off the northwestern Philippines, is described as the holotype of Notoraja subtilispinosa sp. nov. which is the second species of this, so far, monotypic genus.
