Calliax jonesi, N. Sp. (Decapoda: Thalassinidea: Callianassidae) from the Northwestern Bahamas

Two specimens of Calliax jonesi, n. sp., were collected from fine carbonate sediments in 3 to 5 m of water at Bimini Harbor, Bahamas. Of the species presently assigned to the genus Calliax de Saint Laurent, 1973, C. jonesi appears to be most closely related to C. quadracuta (Biffar, 1970), presently known from the Atlantic coast of Venezuela and the Florida Keys. Calliax jonesi is distinguished from C. quadracuta by: (1) the absence of a distal spinose process on the dorsal and ventral margins of the carpus of the first pair of chelipeds, (2) the armature and shape of uropods and telson, and (3) the shape of male first pleopod. Calliax jonesi, C. quadracuta, and at least two undescribed species from the northwestern Atlantic appear to form a closely related species complex which may not be congeneric with the type species, C. lobata (de Gaillande & Lagardère, 1966), and other species assigned to Calliax

Notes on the Genus Probythinella Thiele, 1928 (Gastropoda: Hydrobiidae) in the Coastal Waters of the Northern Gulf of Mexico and the Taxonomic Status of Vioscalba louisianae Morrison, 1965

The gastropod genus Probythinella Thiele, 1928, is considered a senior synonym of Vioscalba Morrison, 1965. Probythinella louisianae (Morrison, 1965) n. comb. tentatively is recognized as a valid species distinct from the closely related P. lacustris (Baker, 1928) and P. protera Pilsbry, 1953. The eastern range of P. louisianae is extended to Mobile Bay, Alabama. Limited observations on the habitat and reproduction of P. louisianae are reported

Observations on the Food and Food Habits of Clapper Rails (Rallus longirostris Boddaert) from Tidal Marshes Along the East and Gulf Coasts of the United States

The feeding habits of five nominal subspecies of clapper rails (Rallus longirostris Boddaert) collected in tidal marshes along the Gulf and Atlantic coasts of the United States are compared. Data on the food from the stomachs of 183 rails were analyzed and the earlier literature critically reviewed. During the warmer months (May through early fall), crabs, predominantly Uca spp., comprised the major part of the food items found. Limited data on a few rails collected during late fall and winter, when Uca spp. are not usually available, indicate that snails then become a major part of the clapper rail’s diet during that part of the year. Earlier studies, which describe the food or feeding habits of clapper rails, are reviewed and the food habits and trophic relationships of some other tidal marsh consumers are discussed. Data from this and previous studies indicate that clapper rails are opportunistic omnivores, and occupy a relatively broad niche within tidal marsh ecosystems. A comparison of available data of the food of five clapper rail subspecies of the eastern United States indicates no distinct differences in their feeding behavior. Differences in the kinds of food eaten appear to simply reflect the types of marsh habitat (fresh, brackish, polyhaline) or geographical location (temperate, subtropical, tropical) in which a particular clapper rail population occurs. The food habits of the king rail are compared with those of the clapper rail and problems concerning the taxonomic status of the “subspecies” of Rallus longirostris are briefly discussed

Studies on the Crustacea of the Turks and Caicos Islands, British West Indies. V. Records of Mysids from Pine Cay, Fort George Cay, Water Cay, and Adjacent Waters

Only 2 species of mysids, Heteromysis spottei and Stygiomysis clarkei, have been previously reported from the Turks and Caicos Islands. Between 1988 and 1990, 21 species of mysids were collected from reef (to 38 m) and shallow non-reef habitats surrounding Pine Cay, Fort George Cay, and Water Cay, Turks and Caicos Islands. One species collected, Anchialina typica, is distributed throughout tropical and subtropical seas. Twelve species (Bowmaniella johnsoni, Dioptromysis paucispinosa, Heteromysis bermudensis, H. guitarti, H. mayana, Mysidium columbiae, M. gracile, M. integrum, Mysidopsis bispinulata, M. brattstromei, Parvimysis bahamensis, and Siriella chierchiae) are widely distributed throughout the subtropical and tropical waters of the Northwest Atlantic. Five species (Amathimysis serrata, A. torleivi, Heteromysis coralina, Mysidopsis mathewsoni, and Siriella chessi) are reported for only the second or third time. Three undescribed species are recognized: 2 species of Amathimysis associated with either gorgonians on reefs or grass beds and a species of Heteromysis collected from sponges on deeper reefs

\u3ci\u3eLeucon (Crymoleucon) rossi\u3c/i\u3e, a New Species (Crustacea: Cumacea: Leuconidae) From the Shelf Waters of the Ross Sea (Antarctica), With a Key to the Genus \u3ci\u3eLeucon\u3c/i\u3e South of 60°S

A new leuconid cumacean, Leucon (Crymoleucon) rossi n. sp., is described from depths of 84 to 458 m in the Ross Sea off the Victoria Land coast. Leucon rossi n. sp. is distinguished from other members of the genus by a combination of characters including 1) a blunt, horizontally directed pseudorostrum) Without a distinctly protruding siphon; 2) strongly developed antennal notch; 3) entire dorsomedian margin of carapace appearing serrate, armed with 14 to 19 anteriorly Curved spines in female (up to 21 in subadult males); 4) a small, but distinct, spine behind the frontal lobe; and 5) the uropodal peduncle slightly shorter than the exopod. After Leucon antarcticus Zimmer, 1907, L. rossi was the second most frequently Occurring cumacean in the samples collected off Victoria Land. Statistical analyses showed significant differences in the proportion of carapace length and height of adult (all incubating in the present Study) and immature females compared to immature males; no adult males were available for study

Tanaidacea (Crustacea: Peracardia) of the Gulf of Mexico. VI. On the Genus Mesotanais Dollfus, 1897 with Descriptions of Two New Species, M. longisetosus and M. vadicola

Two new species of tanaidaceans belonging to the family Leptocheliidae were collected from the continental shelves and slopes of the eastem and Gulf coasts of the United States. Both of these species are assigned to the poorly known genus Mesotanais Dollfus, 1897. Mesotanais is unique within the Leptocheliidae because its members lack eyes. The second supposedly important generic character, uniramous uropods, reported in the original description is considered to be a misdiagnosis. The assumption of this error is supported by the rediscovery of the type-species, Mesotanais dubius Dollfus, 1897 (Sieg and Bird, in press). In the present study, the genus Mesotanais is rediagnosed and the two new species from the western Atlantic are described. Mesotanais longisetosus n. sp. can be distinguished from M. vadicola n. sp. by a variety of characters including the much longer terminal setae on antenna 1, the distinctly more elongate carpus of the cheliped, and the shape of the pars molaris of the mandible. Mesotanais longisetosus appears to be closely related to the type-species, M. dubius known from the eastern Atlantic. It is distinguished from M. dubius by having an elongate distal seta on the carpus and more styliform dactylus of the first peraeopod, and by the presence of two short, distal, tergal spines on the merus of peraeopods 4-6. Mesotanais vadicola occurred at depths of 22-865 m, while M. longisetosus was collected mainly from the upper continental slope at depths of 545-1386 m. Between 500 m and 900 m there is a broad area of overlap in the distribution of the two species, but with increasing depth M. vadicola is replaced by M. longisetosus

Tanaidacea (Crustacea: Peracardia) of the Gulf of Mexico. IV. On Nototanoides trifurcatus Gen. Nov., Sp. Nov., with a Key to the Genera of the Nototanaidae

Nototanoides trifurcatus gen. nov., sp. nov. is described and illustrated from the Gulf of Mexico. Nototanoides differs from the other genera of the family by the male possessing a vestigial maxilliped. It most closely resembles the genera Nototanais and Androtanais. In addition to the differences of the maxillipeds the males of Nototanoides can be separated by the 4-segmented antenna 1 and the females are distinguished by the trifurcate spine on the second segment of the palp of the maxilliped. A key to known genera of the family Nototanaidae is presented
