They contain a subsutural subsquamose carina, and are encircled by numerous subequal granulose lirae. The body whorl is acutely carinated below the middle, slightly excavated above and flat below the carina. The base of the shell is white with an outer zone of purple red, concentrically ornamented with series of granules. The umbilical region has a white smooth callus, its margin stained with yellow.
