The upper ones are slightly extended outwards and plicate, tuberculate or undulating at the sutures.

The body whorl is beaded, but smoother than the preceding, or radiately finely wrinkled, or nearly smooth, angulate at the periphery.

The base of the shell is flat, concentrically lirate, the ribs smooth, wide, separated by shallow grooves, obsolete toward the outer margin.

The basal margin is straight, not concave in the middle, deeply notched at its junction with the columella.
