The fusiform shell is dark white or straw-colored. It contains 8-10 whorls (in the holotype the protoconch is lacking). The suture is profoundly impressed. The whole build of the shell is coarse, though of a light rather than massive consistency. Particularly conspicuous are the spiral sulci deeply furrowing the summit of each whorl, leaving a narrow noduled space between them and the sutures. The ovate aperture has a dark interior. The thin outer lip is slightly expanded. The sinus is wide and deep. The white columella is straight. The siphonal canal is short and straight.
