Description

The size of the shell varies between 25 mm and 50 mm. The solid, imperforate shell has a conoid shape. It is more or less elevated. The 5-6 whorls are obliquely radiately costate, imbricately spinose at the periphery. The body whorl is carinated, carina with about ten long vaulted spines. The base of the shell contains about ten concentric squamose lirae. The white columella is oblique and is generally rosy margined, rarely bluish. The aperture is angulated.[2]

The white or green operculum is granulose outside. The animal has no lateral filaments.
