are larger still and more ovate in form, with less ascending 

 secondaries. They are intermediate in size among Lesquer- 

 eux's figures of L. frotcacfolia.

Recorded from the Raritan, locality not given ; Mataw^an, 

 Cliff wood, N. J. ; Dakota group, Kansas and Minn. (?) ; Cre- 

 taceous, Glen Cove, L. I., Martha's Vineyard and Block 

 Island; Middle Cretaceous at Atane and Patoot, Greenland. 



This is another species which was very common through- 

 out eastern North America from Greenland to New Jersey 

 during the Middle Cretaceous. The leaves were rather vari- 

 able in outline, Newberry's Amboy Clay forms and those 

 from Cliff wood which Hollick refers to this species being con- 

 siderably broader than the majority of Heer's specimens. 

 The leaves from the Dakota which Lesquereux identifies 

 with this species are, on the other hand, smaller and agree 

 fairly well with the leaves in our collections which seem to 

 belong to this species. The latter agree closely with Heer's 

 figures and differ considerably from Hollick's forms from 

 this formation. About the same size as the Block Island 

 leaf which Hollick refers to this species.

A small lanceolate Lauraceous leaf about 8 cm. long and 

 1.5 cm. in greatest width, which is at a point about half way 

 between the apex and base, the blade tapering about equally 

 in both directions ; secondaries four or five on each side,
