diagnosis. The close agreement between the English specimens 

 and some of the larger fossils referred by Fontaine, in his 

 Monograph- of the Potomac Flora, to the genus Nageiopsis, leads 

 me to adopt this name, although it is not improbable that the 

 genus Araucaria may prove to be the nearest living representative. 

 A specimen of similar form to that from the Inferior Oolite of 

 Yorkshire has been described from the Wealden beds of Sussex, 1 

 but the two types are probably not specifically identical. 



One of the Whitby specimens (2377) bears a label on which is 

 written "Probably the leaves of Araucaria Phillipsi" Nathorst, 

 in his notes on English specimens, refers to what is probably the 

 same plant; he speaks of fragments of branches in the Whitby

Without more evidence we cannot decide definitely between the 

 Podocarpeac and Araucariinae as the family in which to include 

 the vegetative shoots referred to the genus Nageiopsis, but on the 

 whole the comparison with Araucaria is more likely to be nearer 

 the truth. 



The English specimens, which I have described for the sake of 

 convenience under a distinct specific name, may prove to be
