The length of the shell attains 2¾ mm, its diameter 1½ mm. (Original description) The minute, ovate-fusiform shell contains 5 slightly convex
whorls, including 1½ smooth whorls in the
protoconch. Its color is blackish to reddish with below the suture a series of white granules. The 12–14 longitudinal ribs are slightly oblique. The sulci (in the upper whorls 4, in the
body whorl about 15) cut through the ribs and produce a somewhat granular appearance. The lira beneath the first sulcus below the suture is that which is white upon the riblets in the black variety. The
aperture is elongate and narrow. The
columella is slightly oblique with a small callus. The outer lip is probably slightly incrassate and at the top slightly sinuate. ==Distribution==
