It is of a reddish-brown color, pleasingly varied with white spots in transverse series, for the most part semi-lunar, and more or less distant.

It is composed of from five to six whorls which are furnished with numerous ribs, often widened, feebly convex, and separated by furrows hardly apparent.

The outer lip is thin, everted, a little undulated, and adorned with a white band the whole length of its interior, with the exception of the edge, which is of a deep brown.

The columella is smooth, polished, and forms at the left of the umbilicus a thick rib, marked by transverse striae, which terminates at the emargination of the base.

[2] The ground color of the shell is a bluish white, covered with irregular spots of a red brown, bordering upon the violet.
