ABYSSOGYRA VEMAE, = Moelleriopsis. Shell minute (1.8 mm. wide), planorbiform, weakly sculptured, and white in color. Periostra cum brown, thin, and pres- ent only in small patches. Whorls two, nearly circular in cross- section. Suture deep. Spire depressed, projecting only slightly above the body whorl. Aperture circular except in the parietal region where it is nearly straight and slightly thickened. Outer and inner lips thin and sharp. Umbilicus wide and extending to the nuclear whorl. Sculpture consisting of lines of growth and two low, medially located, revolving carinae, one located on the dorsal side of the whorls and one located ventrally. Two additional revolving carinae intersect the ends of the straight parietal lip the upper one borders the suture, the lower ascends into the umbilicus. Nuclear portion bulbous, unsculptured, and consisting of one-half whorl. Operculum thin, corneous, yellowish gray, multispiral, and spirally ridged. holotype major diameter 1.8 mm. minor diameter 1.3 mm. height 0.9 mm. Types. The holotype was collected at station 49 (1497 fathoms, 56°43' S, 27°41' W, Atlantic Indian Antarctic Basin, south of Traverse Island, South Sandwich Islands). Only one specimen, a living one, was obtained. The holotype is in the Museum of Comparative Zoology, no. 224962. Remarks. As stated above, in shell characters this species resembles a Cyclostrema without prominent sculpturing. It is probably closest to Abyssogyra normani (Dautzenberg and Fischer) but that species differs in having the aperture width approximately one-third the width of the shell and the spiral carinae very faintly developed, while in vemae, the aperture is approximately one-half the width of the shell and the carinae are rather well developed. It is also somewhat similar to Homalogyra denticostata Jeffreys 1884, except that in that species the spire is depressed below the level of the body whorl and the concentric sculpturing is slightly sigmoid and more prominent. Records. Known only from the type locality.
