Cyrtoclymenia angustiseptata (Münster, 1832) from the late P. jugosus  and D. trigonica  Zones at Kowala in the Holy Cross Mountains and Dzikowiec in the Sudetes.

Diagnoza

Umbo covers almost half of the whorl diameter in mature specimens, much less in juveniles, smooth flattened flanks of the conch.

Porównanie

Distinction between this species and C. plicata (Münster, 1832) is rather doubtful on purely morphological grounds.
