Kosmoclymenia undulata (Münster, 1832) from the late P. jugosus Zone at Dzikowiec in the Sudetes and at between Stokówka and Besówka in the Holy Cross Mountain.

Kosmoclymenia undulata; growth lines, suture, septal geometry and outline of the shell.

Diagnoza

Serially distributed blade-like transverse expansions of the aperture ventrally prominent; deep infundibular sinus of the aperture; nearly circular whorl cross section until conch maturity.

Porównanie

The large specimen from Kowala attributed to K. wocklumeri  because of its angular umbo, is here transferred to K. undulata, as this is rather the character of this species. Also the material of K. venusta Czarnocki, 1989 from the locality between Besówka and Stokówka probably represents this species, as suggested by the appearance of fragmentarily preserved growth lines on one specimen.
