Dorsal view: chambers slightly longer concentrically, weakly inflated; sutures slightly depressed; intercameral sutures directed and curved posteriorly. Ventral view: chambers weakly inflated; intercameral sutures radial, meeting at tight umbilicus; aperture umbilical, highly arched, pushed distally, with a thick lip. Lateral view: smoothly rounded. Wall surface thickened, fairly densely perforate, weakly cancellate prior to final chamber.
