PLATE XL. 



Pecopteris. Sp. 



We have no information respecting this specimen. 



The original drawing by Prior (presumably of the 

 natural size) is twice the size of our Plate. 



A pencil note on the back of the draAving gives the 

 generic name Steffensia. This is an obvious mistake, 

 however. The fronds figured are in some respects very 

 like Pecopteris obtusifolia, Murray ("Fossil Flora," Plate 

 CLVIII.)
