Type characteristic of the Pocahontas or lowest Pottsville. 

 It gave rise to numerous variations, several of which are 

 distinct species. In the upper part (Quinnimont formation) 

 of the lower Pottsville it is replaced by a group of forms, 

 generally listed as N. Smithii Lesq. (see below), while in the 

 middle Pottsville it is followed by forms probably indis- 

 tinguishable from N. Schlehani Stur. 

 NEUROPTERIS SMITHII Lesquereux.

 ville group ; Clark and Quinnimont formations] . 



This species, everywhere present in the lower Pottsville, 

 and represented by derivatives in the middle Pottsville, be- 

 longs to the group referred by European paleobotanists to 

 Neuropteris Schlehani.
