Original Description
Extra details from original publication
Les Rotalies, qu'il faut nommer rotalites, parce qu'on n'en connoit que de fossiles, sont de tres-petites coquilles en spirale orbiculaire, convexes ou un peu coniques en dessus, dont les tours sont contigus et distincts, et dont la base, qui est la partie la plus large de la coquille, est aplatie, tuberculeuse ou granuleuse, et garnie de rayons onduleux. Ces rayons sont les interstices des saillies que font les loges du dernier tour de la spirale.
L'ouverture de la coquille est celle de sa derniere loge; elle est marginale, trigone, et semble renversee ou dirigee vers la base. Les cloisons transversales qui separent les loges sont dirigees comme des rayons vers le centre ou l'axe de la coquille; en sorte que les loges sont legerement coniques.
