These snails usually live in the sand in fairly shallow water in tropical and temperate regions of the world. Most species are predators of marine bivalves.[3][4][5]

Description

The thin shell is not umbilicated. The spire is elongated with the suture enamelled. The inner lip has the callus moderate, defined. The outer lip is simple. [6]
