The rather high shell is turriculate and contains seven convex whorls, subangular at the periphery, separated by a simple suture. The whorls contain longitudinal, nodulose ribs (13 on the penultimate whorl). The aperture is narrow and is half as long as the length of the shell. The front of the columella is slightly twisted and has a small callus. The outer lip is simple and sharp. It forms a rather narrow sinus.
