Sculpture: Rather distant spiral lirae, sometimes obsolete, crossed by oblique growth-lines.

The protoconch consists of two flatly convex whorls, which are finely spirally lirate with very distinct oblique growth-lines.

The body whorl is large, concave below the suture, obtusely angulate at the periphery and eroded in front of the aperture.

The outer lip is convex, sharp, black-edged inside, followed by a white opaque band which continues as a pearly stripe over the umbilical tract, parallel to the columella, and connects the terminations of the peristome.

The umbilical tract is bounded on the outer lower margin by green, grey, or brown.
