acuteness which they exhibit. It is exceedingly common and character- 
istic of the Kootenay, being present at numerous localities in the Crows- 
nest Pass region of Alberta, as well as in British Columbia and Montana. 
It is also found in the Bull Head Mountain sandstone and the Kome 
beds of western Greenland, the last being the type locality. As the pin- 
nules do not meet medianly on the rachis and they are not contracted proxi- 
mad I have transferred it from Zamites to the genus Pterophyllum. The 
oldest name available, acutipennis, is not especially appropriate as the 
pinnules are more often obtuse instead of acute. The species occurs in 
the Lower Blairmore, but is not so prominent at that horizon as in the 
Kootenay. 
Occurrence. Kootenay; localities CK1, CK2, CM1, CN1 (very abund- 
ant), CN2, CQ4, DG1, and DH1. Lower Blairmore; localities CH5, 
and CH7 (?). 
Genus, cycadolepis Saporta 
Cycadolepis sp. 
Plate VII, figure 7 
An unsymmetrical obovate scale of considerable consistency and 
about 2-75 cms. in length by about 1 cm. in maximum width appears to 
represent a carpellary or antheriferous scale of some species of cycado- 
phyte. 
The genus Cycadolepis was proposed by Saporta 1 for detached bud 
scales of cycadean fronds, but it was extended by Seward 2 to include 
petiolar bases and isolated carpellary or antheriferous scales which show 
no traces of ovules or pollen sacs. 
Occurrence. Kootenay: locality CN1.

This species is superficially like Pseudocycas unjiga which is so common 
in the Upper Blairmore, but lacks the double midrib of the latter. It was 
described originally from the European Lower Cretaceous and has been 
recorded on this continent from the Patuxent formation of the Atlantic 
Coastal Plain, and the Knoxville and Hometown beds of California. It 
has not been recognized in the Kootenay of this or other areas. 
Occurrence. Lower Blairmore; localities CH7, I) A3, and DB2.
