however, since this similarity runs through all the members of this 

 genus and these two species are so widely removed geographically it 

 has seemed best to maintain their distinctness. B. ohesiforme Saporta * 

 from beds of Albian age in Portugal is also very similar to the forms 

 under discussion. This species in its more slender specimens approaches 

 very close to certain forms from the Upper Cretaceous of the Southern 

 Coastal Plain (Tuscaloosa formation of Alabama, Eutaw formation of 

 Georgia), which the writer has referred to the usually somewhat larger, 

 more striate-leafed form Brachyphyllum macro carpum Newb. 



Occurrence. — Patusent Formation. Trents Eeach and near Dutch 

 Gap, Virginia. Patapsco Formation. Ft. Foote, Federal Hill, near 

 Glymont, Stump JSTeck, Maryland; near Widewater, near Brooke, Dum- 

 fries Landing, Virginia. *

Description. — "Twigs branching sparingly and dichotomously ; leaves 

 and leaf-scars elliptical to subrhombic, with the longer dimensions in 

 the direction of the length of the twigs; leaves convex, spirally arranged, 

 showing a keel in their upper portions, closely appressed, contiguous, 

 prolonged very slightly at the tips, branches cylindrical, of the same 

 thickness throughout; so far as can be seen about 4 mm. in diameter,"
