Description
The shell size varies between 27 mm and 50 mm
The elongated shell is conical, and slightly turreted. It is of a bluish or ashy white color. The spire is very pointed at its summit. It is composed of nine or ten slightly convex whorls, united by a shallow suture, and furnished at their upper part with very close small folds or granulations. tTese folds form a girdle, and crown the whorls, which are again ornamented throughout their whole length with transverse thin ridges, more strongly prominent towards the base. Tthere appear, besides, upon the body whorl, oblique striae of growth pretty apparent, and presenting sometimes the appearance of varices. One or two striae separate also the folds from the upper marginal edge. The aperture is oblong, slightly narrowed, dilated at its base, where it is terminated by a very deep and slightly oblique emargination. The interior of the aperture is of a brown fawn color. The outer lip is white, thin and sharp. The columella is white and rounded.
