the margins. In the other species mentioned they are less numerous and 

 more curved and the marginal teeth are coarser. 



Formation and locality : Cretaceous (Puget Sound group). Chuckanutz, 

 near Bellingham Bay, Washington. 



Quercus gracilis Newb. 

 PI. LXVII, fig. 4. 

 Proc. U. S Nat. Mus., Vol. V (March 21, 1883), p. 504. 



" Leaves narrow, lanceolate, long-pointed, acute, wedge-shaped at the 

 base; margins set with remote, low, acute teeth ; nervation regular and fine; 

 nerve branches fifteen to twenty on each side, curved gently upward, and 

 terminating in the marginal teeth." 



Collected by Dr. J. S. Newberry. 



This is another of the lanceolate, serrate-leaved oaks of which Q. Dry- 

 meja Ung. (Chlor. Protog., p. 113, PI. XXXII, figs. 1-4) may be considered 

 as a type. It differs from that species, however, in its more crowded 

 nervation, smaller teeth, and shallower sinuses. 



In the figure given the nervation is represented as too strong, and the 

 marginal teeth are not sufficiently acute. Several very beautifully pre- 

 served specimens are before us, which give a very exact and complete 

 view of it, and its resemblance to Q. Drymeja is so strong that if it had 

 occurred in the same horizon and locality there would have been no pro- 

 priety in separating them; but in addition to the differences that have 

 been mentioned, the geological horizons are so different that the probability 

 of finding any identity of species is extremely small. For the present, 

 therefore, it has been thought best to regard this as distinct from the great 

 number of leaves that have been in North America and Europe referred to 

 Q. Drymeja. 



Formation and locality: Cretaceous (Montana group). Point of Rocks, 



Wyoming.
