This idcntilifiitiou rests on two fragments of A^ery large leaves that 

 are not in niy opinion well enough preserved to warrant specific deter- 

 mination. They can hardly belong to P. Raynolihll^ as I^es({U(n-eux 

 has stated, nor do they seem to be parts of either P. vohlUx or /*. 

 aeeroldes. Just what they are I am unable to say at present.

I have before me as 1 write the type of Newberry's CrativyiistJdves- 

 ce/is (LT. S. Nat. Mus., No. 7088) and a part of Lesquereux's tyjjcii of 

 his Jli/r/'ca diver^^'i folia as descril)ed first from Florissant, Colorado. 

 The type of the Bridge (-reek example referred by Lesquereux to J/i 

 diversifoUa (op. cit., PI. L, fig. 10) is in the paleontological collection 

 of the University of California, where T have seen it, and there can 

 be no doubt of its al)Solute identity with Newberry's (^rativgus flaves- 

 censoi prior date, and I have so referred it. In regard to the status 

 of the Florissant specimens" I am somewhat in doubt. The National 

 Museum collection does not appear to contain all of the figured 

 examples and, judging from the figures alone, it would seem that they 

 represent more than one species. Figs. T. S, 11, 12, and 14 are 

 seemingly identical with the Bridge Creek species, yet they show a 

 tendency to have sharpiy toothed lobes, a condition not often i)resent 

 in the former species. In the absence of a sufficient amount of mate- 

 rial (these leaves appear to be rare in the Bridge Creek collections) it 

 has seemed best to leave it for future settlement. 



Locality. — Bridge Creek, Grant County, Oregon. Collected by 

 Rev. Thomas Condon and Maj. Charles E. Bendire (U. S. Nat. Mus., 

 No. 8489). Type of Lesquereux's fig. 10, op. cit., in Mus. Univ. Cal., 

 No. 1757.
