They are marked by 8 strongly incised spiral lines on the first and second and 20 upon the third, between the sutures. The sutures are well marked. The periphery and the base of the body whorl are well rounded. They are marked by numerous spiral striations, which are a little weaker than those between the periphery and summit of the body whorl.

It is provided with a strong fold at its insertion.
