Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. P. Popenoe and L. R. Saul 1987 | Bucciniform to pyriform gastropods of medium to moderately large size with a subangulate whorl periphery which is ornamented by fewer than five spiral ribs. The crossing of these spiral ribs by short axial ribs produces the characteristic noded periphery. The edge of the outer lip anterior to the periphery is fimbriated. With the exception of the geologically earliest species, P. cretacea (Cooper), all species have an expanded inner lip that is developed at growth halts and is the inner lip equivalent of a varix. |
