The smooth protoconch is sinusigera in form, the exposed portion of its lower lip concave.

The aperture is narrow oblong, obliquely angled behind, truncated in front.

The anal sinus is deep, separated from the body whorl by a thick callous ridge.

Sculpture : The shell shows regular low axial ridges, about 15 on the body whorl, slightly constricted at their upper ends near the suture.

The shell is white, with a faint brown band, dark in patches, along the lower edge of the whorls, but not reaching the outer lip, where, at its anterior end, two narrow brown bands are very faintly indicated.
