The basic color of these oval-shaped smooth and shiny shells is whitish, with irregular greenish or blueish blotches or trasversal bands and brown small brown spots on the edges of both sides. Also the extremities show two larger brown blotches. The base is mainly whitish, with a narrow sinuous aperture with several short teeth. In the living cowries the mantle is very thin and transparent, with short papillae and external antennae.
