The rest are deeply and smoothly concave at the top, then slightly convex, furnished with numerous oblique rounded smooth close-set ribs, the ribs terminating in a well-defined angle at the top. The body whorl is about equal in length to the spire, slightly convex above and tapering below. It is spirally lirate towards the base and scarcely rostrate. The aperture is oblong, its interior smooth and, brown. The columella is rather straight . The outer lip is thin, arched, with a moderate posterior sinus situated close to the suture.[2]
