Description

The length of the shell attains 5½ mm, its diameter 2½ mm.

(Original description) The shell is globosely conical, somewhat peculiarly twisted or bent, with a distinct suture. It is white, with a pink tinge towards the top. The apex is very obtuse, with a decollated appearance. The shell contains 6 whorls. They are longitudinally ribbed, with the ribs thick and prominent, distantly transversely striated, so as to present a granulose appearance. At the base of the body whorl occur several rows of small granules. The columella is peculiarly twisted. The aperture is narrowly contracted. The outer lip is thick, in the middle bent inwards.[2]

Distribution

This marine species occurs off Sri Lanka.
