 Jurassic species).

 Description. — "D. foliis bipinnatis, pinnulis erectis, oblongo- 



lanceolatis, basi attenuatis, integ-errimis, nervis subtilissimis, 



nervillis angulo acute egredientibus, erectis." Heer, 1882. 



Both of Heer's types, which are here united with Newberry's 

 species, are small fragments of ultimate pinnae, which their 

 author confesses are very similar, a fact well brought out by a 

 comparison of the figured specimens. The material from Wood- 

 bridge is more ample, and as may be seen lower down on the 

 frond the pinnules become toothed and finely pinnatifid, a feature 

 not seen in the Greenland material. There is slight reason, 

 however, for doubting their identity, Newberry himself pointed 

 out that Dicksonia borealis of Heer was probably identical with 

 his Amboy clay species. Although common at Woodbridge, N. 

 J., this species has not been found elsewhere in the Coastal Plain 

 except for a single specimen which the writer discovered recently 

 in the Tuscaloosa formation of Alabama. It is present at both 

 the Atane and Patoot horizons of Greenland.
