of the pinnules on the frond-long, narrow, almost straight proximal pinnules 
passing gradually into more or less short, broad, and falcate distal pinnules. 
This species, which is not uncommon in both the Kootenay and the 
Lower Blairmore of Alberta, is not very different from the widespread 
Lower Cretaceous type of Cladophlebis commonly referred to the species 
albertsii of Brongniart. As here understood it exhibits considerable minor 
variation from specimen to specimen, but these variations show so many 
gradations and are so readily explained that any specific segregation of 
them seems unwarranted. In general the pinnules are larger and rela- 
tively much wider than in Cladophlebis albertsii.

This European Lower Cretaceous species is supposed to be represented 
on this continent by the material represented by the foregoing synonymy. 
These represent occurrences in the early and late Potomac of the Atlantic 
Coastal Plain, and the Knoxville of California, the Fuson formation of 
Wyoming, and the species is also probably represented in the Koine beds 
of Greenland. 
It is a minor element in the Lower Blairmore of Alberta, being present 
only at locality CH7.

Small fragments of a fruiting fern of the Dicksonia type and typically 
that of the family Cyatheaceae occur in both the Kootenay and Lower 
Blairmore of Alberta. I have referred them both to a single species,
