Ventral view: chambers highly inflated, sutures radial to curved posteriorly, meet at slightly open umbilicus; aperture an umbilical--extraumbilical interiomarginal very low slit. Lateral view: dorsoperipheral shoulder rounded; dorsal side of final chamber slightly concave; ventral face, umbilical shoulder, and apertural face smoothly rounded, convex, and high. Wall smooth but densely pustulose.
