The very strong and solid shell has a depressed conoidal shape with a rounded periphery and a profoundly umbilicate axis.

It bears 18 or 19 crowded, closely granose cinguli, of which the 1st, 3d, 5th, 7th, 9th and two upon the base are composed of alternate black and white granules.

The basal lip, the outer margin of the umbilicus and the parietal wall are provided with wrinkle-like plicae.

The columella is very oblique, terminating below in a square prominence, contorted above, and inserted on the side of the umbilicus.

[2] Widely occurring in the shallow subtidal zone throughout the tropics of the Indo-Pacific region, from Hawaiian Islands to the Red Sea, the Gulf of Oman and Madagascar.
