Diagnoza

Porównanie

Actually, the only basis for identification of this species is its geological age as the distinctions in the conch shape and course of internal thickenings are hardly significant. Specimens from Kowala do not not have the original shell preserved, so features of shell ornamentation cannot be taken into accout.
