Cirsonella gaudryi is a species of sea snail, a marine gastropod mollusk in the family Skeneidae.[1]
Description
The height of the shell attains 2.5 mm. The rather solid, shining, white shell has a turbinate shape. it has a narrow umbilicus. The spire consists of 3½ convex whorls, separated by a marked suture. The surface is smooth, except for the base which contains two or three very faint concentric striae. The circular aperture has a continuous peristome. The columella has a thick callus that connects to the convexity of the penultimate whorl. it covers for the greater part the umbilicus, that is reduced to a narrow, arched chink. The lip is simple.[2]
