Description

edit

The thin shell is globosely pyriform with the axis perforate and the umbilicus partly concealed by the reflected inner lip. The spire is obtuse. The aperture is oblong, produced anteriorly into a wide subrecurved canal.

Rapa differs from Rapana not only in the produced canal of the aperture and thin simple whorls, but in the free, reflexed inner lip and moderate umbilicus.[2]
