Type, Small fish wanting extremity of tail. 
A species closely related to P. freieslebeni , but distinguished, 
according to the original diagnosis, by the less tapering form of the 
caudal region, the relatively larger size of the head, the greater 
breadth of the opercular apparatus, and the comparative straightness 
and elongation of the branchiostegal rays. The scales of the flank are 
also said to be less vertically elongated than those of the type species 
—a somewhat doubtful distinction. 
Form. <$f Loc, Upper Permian: Thuringia.
