Quercus Hollickii sp. nov. Pl. 57. f. 1, 2. 
Leaves subcoriaceous, obovate, obtuse, gradually narrow- 
ing to the base; secondaries strong, ieee and parallel, 
alternate, camptodrome, angle of divergence about 50°; 
basal one third of the margin entire, above rather irregularly 
dentate. 
These specimens evidently represent a leaf about 9 cm. in 
length by about 4.5 cm. in greatest width. 
I have been unable to refer this to any of the described 
species of Quercus although it resembles several; in outline 
it is similar to 2. Wardiana Lesq.* from the Dakota group, 
but the latter is 50 per cent. larger and with different vena- 
tion. There is also a resemblance to Newberry’s 2. ellp- 
t7ca t but the secondaries are straighter, more ascending and 
more regularly arched in our specimen. Again, it may be 
compared to the Tertiary 2, Olafsent Heer, but the latter 
has the leaves more oval, margin more dentate, secondaries 
craspedodrome and straighter, greatly resembling Les- 
quereux’s ~/. 48. f. 4 from the Fort Union Beds; in the 
latter, however, some of the upper secondaries run directly 
to the dentate points of the margin. There is, further, a re- 
semblance to 2. Vevadensis Lesq., from the Pacific Coast 
Miocene, which however has the secondaries straighter and 
subcraspedodrome. 
Considerable similarity is to be noted with various leaves 
referred to Celastrophyllum, as for instance C. grandifolium 
Newb., which is common in the Raritan (localities not given) ; 
our leaf is considerably shorter and relatively wider, more 
obovate in outline, with a more tapering base, straighter mid- 
rib and more regular secondaries.
