---|---|---|
D.K. Pandey et al. 2012 | Shell moderately large, incomplete, evolute, compressed. Whorl section suboval, maximum inlation at one-third of whorl height. Ornamentation consists of prorsiradiate, moderately coarse, sharp, and sparse primary ribs originating near the umbilical suture rather rursiradiately. Primaries cross the rounded umbilical margin more or less straight and branch at three-quarters of whorl height into two secondary ribs. Occasionally single, undivided primaries present, demarcating shallow constrictions. Secondaries cross the venter with distinct forward-directed convexity. |
