Pl. 3, figs. 7, 8, pl. 8, figs. 10-13.

D e s c r i p t i o n: Ancyrochitina with a conical chamber. Flanks of the chamber are sometimes convex. The neck is tubular, in some cases widened in an apertural direction. The base is flat to convex. Processes are on the basal edge. Processes can be present on the neck. The chamber constitutes one third to more than half of the length of the vesicle. The basal edge is rounded to sharp. The wall of the vesicle is very thin at the apertural pole, hence often broken.
