Description

The size of the shell varies between 7 mm and 13 mm. The very solid, imperforate shell has a conical shape. It is flesh-colored, painted with radiating white streaks, the apex blackish-violet. The granulate whorls are a little convex, the last one rounded-angulate, above a little concave. The granules of the surface are hemispherical, closely crowded. The superior whorls are entirely flat and contain 6 or 8 granulate cinguli, close, separated by a narrow granulate line. The base of the shell is granose-cingulate, with about 8 principal cinguli, alternating with smaller ones. The aperture is rhomboidal and depressed. The outer lip is superficially sulcate within, corresponding to the principal lirae of the outer surface. The columella is oblique, somewhat twisted, cylindrical, without tooth at its base.[2]
