Bathybembix
''Bathybembix'' is a genus of deep-water sea snails, marine gastropod mollusks in the family Calliotropidae. This genus was originally called ''Bembix'' by Robert B. Watson (,〔Watson, Journ. Linn. Soc. London 1879 vol. 14 p. 603〕 but as this was a junior homonym of ''Bembix'' Fabricius, 1775 (), it was declared invalid. It was renamed in 1893 by Crosse as ''Bathybembix'' 〔Crosse, Journ. de Conchyl. 1893, vol. 40 p. 288〕 ==Description== The shell has a conical shape with a high spire. It is carinated and umbilicated. The base of the shell is inflated. The shell is covered with a thin, extremely persistent, smooth, fibrous epidermis, The epidermis swells up and becomes pustulated in water. The axis of the shell is perforated, and the columella is thin, reverted, and merely angulated in front.〔( Watson R. B. (1878-1883). Mollusca of H. M. S. Challenger Expedition.
