Original Description
[Google Translated from French]: Free shell, univalve, partitioned, disc-shaped, and spirally contoured, nippled on the two centers; the last turn of the whorl enclosing all the others; carinated and armed back; triangular mouth, covered by a diaphragm, and receiving in its middle the return of the whorl, pierced at the external angle by a pear-shaped rimule; united partitions.
Extra details from original publication
[Google Translated from French]: There is a general observation, which appears to apply to all partitioned and cellular shells: they are never covered with moss or marine cloth, and they are always smooth and polished; until now we have not yet found an exception to this rule, and we believe we can infer that the mollusks which construct them embrace them on the outside with their mantle, making them smooth and iridescent, polished and pearly: not that they are internal shells or enclosed in the body of a mollusk, as we will see for some other genera, but the shells which constitute those of which we are speaking are entirely covered by a mantle which their mollusks open at will.
