Description
The shell size varies between 16 mm and 32 mm
The shell has an ovate, ventricose shape. The pointed spire is composed of six or seven convex whorls. It is ornamented upon its whole surface with granular, longitudinal folds, and transverse striae. The suture is very distinct, formed by a small canal, and bordered with closer tubercles, principally upon the body whorl. This is very much inflated, and composes almost half of the shell. The aperture is rounded. The thin outer lip is arcuated. It is folded upon the edge, ornamented internally with raised striae, which are continued within the shell. The inner lip expands upon the columella, which is truncated towards the top, and extends like a raised lip towards the base. It is covered lengthwise by two or three slightly marked, oblique folds. The interior of this shell is of a diaphanous white, like the surface, which, moreover, is covered with reddish clouds.
