Abundant material of the rare lobster genus Thaumastocheles, recently collected from Taiwan, led to an extensive survey of the Indo-Pacific specimens of this genus deposited at various institutions. Altogether 82 specimes of Thaumastocheles from the Indo-Pacific (Madagascar to Japan and New Caledonia at depths of 70-1,753 m) were examined and 2 distinct species are recognized. The 2 species, T. japonicus Calman, 1913, and T dochmiodon, new species, differ mainly in the shape of the cutting teeth of the first chelae and the lateral carinae of the abdominal tergites. Both species are found in Japan, Taiwan, and the South China Sea.

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 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.

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

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.
