The transverse striae are very fine, and the longitudinal ribs regular and rounded. The colour is yellowish white, suffused with greyish green, with transverse lines of light brown, and a dark brown band, interrupted by the ribs, at the angle of the whorls, and another near the base of the body-whorl. The aperture is oblong and very narrow.The outer lip is acute and incrassate.[2] DistributionThis marine species occurs off Pakistan and West India. References1. ^1 WoRMS (2009).
