Remarks. — The specimens included here agree entirely with Pecopteris arborescens 

 in size and form of the pinnules, but as the nervation is not clearly shown, the record 

 is marked with a ' querry.' 



Locality A. 



Pecopteris (Cyatheites), sp. 



Remarks. — Possibly more than one species is included here, but as the specimens 

 are fragmentary and the nervation not shown, it is impossible to determine them 

 specifically with any degree of certainty. It is rather remarkable that among the 

 Pecopteris none of the specimens showed the nervation, whereas in some of the other 

 ferns found with them the nervation was clearly seen. 



Localities B, D. 



Alethopteris, Sternberg. 

 Alethopteris aquilina, Schlotheim, sp.

1828. Pecopteris Schlotheimii, Brongt., Prodrome, p. 57. 



Remarks. — The examples from Jockie's Syke agree entirely with Schlotheim's 

 figures. I will not at present enter into the question of the identity or otherwise of 

 Brongniart's Pecopteris aquilina * with Schlotheim's plant, as I hope at another time 

 to publish some notes on this subject. 



Localities B, C. 



Alethopteris Grandini, Brongniart, sp. 



Alethopteris Grandini, Brongt. See ante, p. 787.
