Original Description

[Original text]: Coquille libre, univalve, cloisonnée, en disque, et contournée en spirale, mamelonnée sur les deux centres; le dernier tour de spire renfermant tous les autres; dos caréné et armé; bouche triangulaire, recouverte par un diaphragme, et recevant dans son milieu le retour de la spire, percée à l’angle extérieur d’une rimule piriforme; cloisons unies.

[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
[Original text]: Il est une observation générale, et qui paroît appartenir à la totalité des coquilles cloisonnées et cellulées; jamais elles ne sont recouvertes de mousse ou de drap marin, et toujours elles sont lisses et polies; jusqu’à présent nous n’avons pas encore trouvé d’exception à cette règle, et nous croyons pouvoir en inférer que les mollusques qui les construisent les embrassent en dehors par leur manteau en les rendant lisses et irisées, polies et nacrées: non pas qu’elles soient des coquilles intérieures ou renfermées dans le corps d’un mollusque, comme nous le verrons pour quelques autres genres, mais les coquilles qui constituent ceux dont nous parlons sont entièrement recouvertes par un manteau que leurs mollusques ouvrent à volonté.

[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.
