The size of the shell attains 55 mm.

The smooth shell is ovate and oblong. Its ground color is whitish, marked with longitudinal reddish lines. The epidermis which covers it, is pretty thick, and of a beautiful chestnut color. The spire is elongated, pointed, composed of seven slightly convex whorls. The whitish aperture is ovate, slightly narrowed towards the upper part, and widened at the base, which is rather deeply emarginated. The thin outer lip is slightly rounded, compressed towards its upper third. The columella shows a white callosity, adhering to the body of the shell, and partially formed by the left lip.[2]

Distribution

This marine species occurs from Argentina to Chile. It also inhabits the rocks of Payta upon the coasts of Peru.
