The length of the shell varies between 14 mm and 36 mm.
The white shell is conical, turreted, polished, elongated, slightly transparent. It has three or four transverse, narrow reddish or chestnut spiral lines on the body whorl, and two on the whorls of the teleoconch. The middle band s always narrowest ; the others are wider and deeper colored. The pointed spire is composed of from ten to twelve distinct, smooth, slightly convex whorls. The body whorl is more inflated than the other whorls. The shell is smooth and umbilicated. The ovate aperture is subrotund at its base, and generally marked within, with very prominent ridges continued upon some specimens even to the edge of the sharp outer lip. The outer lip is often lirate within. The columella is slightly arcuated, recurved around the umbilicus. It is furnished at its base with three folds, the upper of which is more prominent than the others. The small umbilicus is cylindrical, narrow and deep.[2] The maximum recorded shell length is 36 mm.[3][4]
