The length of the shell attains 15 mm, its diameter 10 mm.

(Original description) The shell contains 6 whorls. The shell is conically ovate, solid, and blackish-brown, with longitudinal striations. It comprises six inflated whorls, separated by a moderately impressed suture. The apex is obtuse.

The aperture is obliquely ovate, subtly angulate at the base. The outer lip is simple and thickened on the inner side. The columella is short and straight, bearing a somewhat callous plication below its midpoint.

The shell features a distinct white band below the suture and a dirty white coloration in the umbilical region.^[2]
