THE DESCRIPTION AND STRATIGRAPHIC RELATIONSHIPS. 417 



The specimens representing this species appear to be the same as the 

 Canadian form, P. serrulata of Hartt,'^ and Zeiller's European form, P. dantata. 

 There seems also to be no essential difference between the plants studied 

 and the forms described and figured by Brongniart as P. plumosa. 



Locality: Yoho School. 



Pecopteris sp. 



PI. II, fig. 8. 



Detached pinnae of a rather delicate Peeopterid plant comparable with 

 P. Miltoni were found at the Yoho School locality. The diagnostic features 

 of those fossils are too obscure for definite determination. 



Pecopteris ef. abhrcviala Brongn. 

 PI. IX, figs. 11, 12 and 13?. 



A few poorly preserved fragmentary plants are doubtfully referred to this 

 species. The shape and size of the pinnules agree rather closely mth forms 

 figured by Zeiller.^^ 



Locality: Fire clay under the Upper Block Coal, Asherville. 



Undermined Pecopteris Species 



A few imperfectly preserved, fragmentary Peeopterid forms are figured in 

 plates VI, IX and X. Fig. 13, pi. VI, represents a plant from the Reels- 

 ville locality; fig. 1, pi. IX, a plant from the Liberty school locality; figs. 

 5 and 6, pi. IX, are of fossils from Schroepferman's mine; fig. 2, pi. X, is a 

 plant from the fire clay under the Upper Block Coal, Asherville.

 The fossils referred to this species closely agree in all essential character- 

 istics with plants from the shales of the Whetstone beds of Indiana. 

 Locality: Yoho School.
