siderably in size, some being larger and some smaller than the 

 Maryland leaf, which agrees with them closely, however, in both 

 outline and venation.

This small, narrow, elongate-leaved willow which Lesquereux 

 regarded as a variety of his species Salix proteacfolia is very com- 

 mon in the Cretaceous of the Atlantic coastal plain and is particu- 

 larly abundant and widespread in the Magothy formation as far as 

 it has been explored in New Jersey, Delaware and Maryland. 

 The forms are here restored to specific rank, as they are obviously 

 distinct from Salix proteaefolia when the latter is correctly charac- 

 terized. As I have discussed these forms at length in the Report 

 of the State Geologist of New Jersey for 1905, they will not be 

 farther considered in this place. Found in the Magothy formation 

 at Cliffwood bluff, Cliffwood Brick Company and Morgan, New 

 Jersey ; Deep Cut, Delaware ; and Grove Point, Maryland.

It is unnecessary to comment upon the forms included under 

 this species, which are shown by the foregoing synonymy. 



It occurs in the Magothy formation at the pits of the Cliffwood 

 Brick Co., N. J., Deep Cut, Del., and Grove Point, Md. ; plate 

 7, figure 2 being a somewhat misleading representation in so far 

 as the venation is shown of a specimen from the latter locality.
