Dorsal view: chambers longer concentrically, barely inflated; sutures barely depressed; intercameral sutures radial to directed and curved posteriorly. Ventral view: chambers inflated; intercameral sutures radial, some curved posteriorly at distal end, meeting at slightly open umbilicus. Lateral view: smoothly rounded, though umbilical shoulder slightly acute in final chamber; aperture umbilical- -extraumbilical, low. Wall smooth with moderately dense pores especially towards periphery; dorsal side thickened, obscuring early chambers.
