The inner margin or dorsum is broadly flattened to slightly concave, sides well rounded, the outer margin or venter arched. The surface is covered with nodes or spines in a regular rhythmic pattern. the siphuncle is near the venter, tubular, without organic deposits. There is a well developed hyponomic sinus for the hydro-jet or hyponome on ventral side of the aperture.
