How the shell is carried
It is evident from several features of the shell and its internal organization that the shell in this genus is carried with its principal axis transverse to the longitudinal axis of the foot; that is, the spire is directed to the right. The flattened surface of the outer whorl thus rests upon the dorsal surface of the foot or upon the substratum when the animal is in a state of aestivation, a position which they had assumed in both instances.
