Diagnoza

Porównanie

A single specimen in the Czarnocki’s collection from a grey crinoidal limestone of his Nodosoclymenia beds at Ostrówka is unusual in having a parabolic section of the venter and gently curved septum also in the umbonal area. A similar specimens occur in the significantly younger strata with Clymenia at Kowala. Septum so steep dorsally resembles that in Clymenia and Kosmoclymenia and this may possibly be a vaulting-free member of that branch. In fact, in sample Ko-187 pyritized juvenile specimens occur closely resembling at this stage conchs of Platyclymenia, do not known so high in the Kowala section. They may belong to this species or to Clymenia.
