D e s c r i p t i o n: Cingulochitina with ovoid to conical chamber. The tubular neck is often flared. The maximal width of the vesicle is at one third of the length of the chamber. Shoulders and flexure are well developed. A ridge-like cingulum does not change the curvature of the bluntly rounded basal edge. A short narrow mucron is observed if the vesicles are not connected. Vesicle twins are common.
