The shell is much depressed, the spire reaches only a trifle above the body whorl.

They are very convex, with a deep suture, and short subsutural folds.

Between these keels runs a row of elongated, slightly oblique tubercles.

Moreover the whole shell is covered with fine spiral striae and still finer growth-striae.

The aperture is very oblique, its upper margin concave near the body whorl, then strongly convex.
