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.
