The imperforate, rather thin, but pretty solid shell has a strictly conical shape.

The surface is densely finely sculptured by spiral lirae crossed by very regular oblique lamellae, producing a clathrate pattern.

The spiral lirae number about 6 on each whorl, but often double as many, by the intercalation of riblets in the interstices.

The periphery has a prominent keel, cord-like, with secondary spiral striae, or bifid, cut into compressed granules, somewhat prominent above the sutures.

The interstices are radiately striate, sometimes with a central riblet.
