From Bogoslovsky, 1980:

Very thin growth striae and parallel to them thin radialribs which are more distinct near the umbilicus and are smoothened near theventral shoulder. Ca. 20 ribs per one whorl. Growth striae on the flanks are weaklyrursiradiate and approaching the ventral margin are bent to form a narrow anddeep, lingulate ventral sinus, which is reflected on the internal mould as weakcrescent-like constrictions.
