The sculpture of the post -embryonic whorls consist of fine somewhat unequal spiral striae, with linear interspaces.

The periphery of the body whorl has semicircular small white spots, usually two together, and at subequal distances.

The first increases slowly, then more rapidly, the upper half convex, the lower slightly concave.

The oblique columella is straight with a distinct tubercle above, and a small denticle at the base.

The deep umbilicus is moderate, extending to the initial whorl, about one-sixth of the greatest diameter.
