Cyclostrema prominulum is a species of sea snail, a marine gastropod mollusk in the family Liotiidae.[1][2]
The height of the shell attains 1 mm and its diameter 2 mm. It is a very minute, deeply umbilicate, white shell with a depressed discoidal shape. The shell contains four whorls. The two apical whorls are very small. The surface is uniformly multilirate. The lirae at the periphery are metamorphosed into a strong, very prominent and acute keel. The aperture is round. The outer lip is thin.[3]
