Whorls 10 to 12½ and moderately convex. Spire attenuate and tapering from the body whorl to form an acute cone. The spire is produced at an angle of 22° to 25°. Aperture subcircular. Lip expanded and reflected but not turned back. It is attached on the parietal area but generally built forward enough to make the aperture holostomatous. Columella short. Parietal tooth centered, rather prominent and extending back for less than ¼ whorl. Columellar tooth small and weak, extending back for nearly ½ whorl. Columella short and somewhat arched. Umbilicus rimately formed and shallow, extending within hardly more than ½ whorl. Suture well defined but only slightly indented. Sculpture consisting of numerous and well-developed axial costae numbering 10 to 13 on the body whorl. Spiral sculpture consisting of numerous incised lines which pass over the axial costae. Surface with the peculiar powder-like element. Agglutinated sand grains rare.
