Material.— One shell, SMF373110 About SMF . Northern Indian Ocean, Krishna-Godavari Basin , Bay of Bengal, offshore eastern India, 15°51.6335’ N, 81°50.2274’ E, 1046 m water depth, 16.68 mbsf level, core NGHP-01-12A; Upper Pleistocene GoogleMaps .

Description.—Elevated, conical, strong rissoid shell. Protoconch paucispiral with large nucleus, one and a quarter whorls, smooth, diameter about 350 µm. Teleoconch with three flattened whorls, sculpture with about 14 broadly undulating axial ribs with protruding pointed nodules on the shoulder, very fine growth lines, narrow undulating shoulder area, deeply impressed suture. Abapically pointed. Ultimate whorl shows fading axial ribs and few weak chords below periphery. Lip broken. Estimated height 2.5 mm.

Remarks.—The single shell is well preserved, apart from a broken lip. The shell is morphologically very similar to the East Atlantic type species. As several congeneric species are similar we refrain from a species determination based on only one specimen.
