species, SalLv Hayei Lesq., and with the Arctic Tertiary, Salix 

 R(2mia, Heer, both of which it resembles in general appearance. 

 The Dakota group leaf, however, is coriaceous, w'ith a coarse 

 venation, blunt apex and more narrow pointed base, and is seen 

 to be quite different from the Raritan species when careful com- 

 parisons are made.

 Quercus raritanensis Berry, Bull. Torrey Club, vol. 36 : 249, 1909. 



Description. — Leaves ovate in outline, subcoriaceous, ap- 

 parently about 8 cm. or 9 cm. in length, by 4.5 cm. in width, 

 pointed above. Margin with coarse pointed teeth separated by 

 rounded sinuses. 



The New Jersey occurrence of this species is based on the 

 single obscure fragment of the terminal half of a leaf figured 

 by Prof. Newberry and correlated with Quercus Johnstrupi 

 Heer, a Greenland species. 



The New Jersey form is obviously not the same as Heer's, 

 which has pointed instead oi rounded sinuses, and is a smaller, 

 more Myrica-like leaf, with the marginal teeth dentate rather 

 than serrate. 



The present species considerably resembles an undescribed 

 Quercus from the Cretaceous of North and South Carolina, but 

 this resemblance cannot be construed as a proof- of identity
