Description Test flat, almost equally biconvex, thickness approximately 1/3 of maximal diameter. At the umbilicus side only the last whorl is visible and the umbilicus isfilled with a large, beaded plug, surrounded by a deep spiral fissure; the sutures are depressed and straight at the umbilical side and some scattered pustules occur with larger beads around the spiral depression.
At the spiral side the sutures are raised and limbate because the keel of the individual chambers continues inward to the spiral suture.
Only some chambers of the last whorl can be discerned, all earlier chambers are obscure, due to the ornamentation which is strongest in the central part of the spiral side.
The periphery is sharp, keeled, lobate in most specimens. [details]
