The spiral lirae increase in number, to about 10 weaker spirals on the upper part and 4 or 5 stronger ones at the lower part of the upper surface, and numerous intermediate ones.

The whole shell is crossed by oblique, fine, but conspicuous growth-striae.

The umbilicus is narrow, in the front view concealed by the columellar margin, with rather smooth walls.

The interior of the aperture is nacreous, with a few shallow grooves, corresponding to the stronger external lirae.

Its outer surface is concave, many-whorled, each whorl divided in two parts, a central one, with oblique, strong and an external part with nearly perpendicular, fine striae.
