214 Rk. T. Hili— Outlying Areas of the Comanche 
to be indicated by previous studies, If more were known of the 
chronologic sequence of the Dakota flora, it would possibly be 
found that the plants identified above belonged to lower or older 
beds. But all that can now be stated is that these species belong 
to the Dakota group as it has usually been accepted, and have 
never before been identified outside of it. 
Very respectfully,

Ill. Lhe Belvidere Shales.—The fossils enumerated by Prof. 
Cragin from these shales, especially in his earlier writings, 
were determined under difficult conditions, remote from large 
libraries and typical collections, and his synonymy is greatly in 
need of revision. 
From “the Neocomian shales,” (the Belvidere shales)—the 
shales lying between the “ Dakota” (No. IV) sandstone at the 
top and the highest layer of the Cheyenne sandstone, as above 
defined, Prof. Cragin in his various papers has reported the 
following fossils.*
