). It is discus-shaped and involute (ww/dm = 0.40; uw/dm = 0.12) and possesses a whorl profile with a rounded umbilical margin, from where the convex flanks converge towards the subacute venter. The ww/wh ratio is 0.77 and the coiling rate is low (WER = 1.72). The last whorl of the specimen is increasingly overlapping upon the umbilicus; therefore, the uw/dm ratio has a value of 0.17 at about

They have a weakly biconvex course with a low dorsolateral projection in some distance from the umbilicus on the inner flank, a very shallow lateral sinus, a low ventrolateral projection and a shallow, broadly V-shaped but closely rounded ventral sinus. The specimen has five shell constrictions, which are almost regularly spaced. They are slightly oblique in their course so that they cross the growth lines at a very acute angle.</paragraph>
