but the flora as determined by Prof. F. H. Knowlton of 'the U. 8. 
Geological Survey consists entirely of species hitherto supposed to 
be peculiar to the Dakota Group, while the flora of the Trinity 
Division of Texas as has been reported by Professor Fontaine is all 
of the non-dicotyledonous Potomac type. The Cheyenne sandstones 
are separated from the true Dakota sands of Kansas by nearly 200 
feet of shale, containing a molluscan fauna composed of fifteen 
species characteristic of the Washita Division of the Comanche 
Series of Texas, and about twenty littoral species peculiar to the 
locality.’ 
In September of the same year Professor Hill published an ex- 
tended article “On Outlying Areas of the Comanche Series in 
Kansas, Oklahoma and New Mexico” in which the flora of the 
Cheyenne sandstone and the fossils of the overlying shales are fully 
discussed. The introductory part of the paper is an excellent de- 
scription of the topographic features of southern Kansas, followed 
by a brief discussion of the correlation of the Cretaceous rocks of 
that region. Professor Hill’s route was from the town of Medicine 
Lodge up the river valley along which the Red-Beds are excellently 
exposed, to Sun City where he crossed the river and made a section 
from the river valley to the top of Stokes Hill (called Black Hills 
in the paper) in the southeastern part of Kiowa county. In dis- 
cussing the former denudation of this region, Professor Hill said 
“Near the head-waters of this river [Medicine Lodge] a thin group of 
Cretaceous formations lies between the Tertiary and the Red-Beds. 
Tc the east the Plains formations rest directly upon the Red-Beds, 
the intervening Cretaceous deposits having there been denuded in 
early Tertiary time.’® Prof. Hill published a complete and accurate 
section of Stokes hill, making a number of divisions in the Kiowa 
shales, which in his article are called Belvidere shales. In a foot 
note Professor Hill stated that since writing his paper “Professor 
Cragin had proposed the name Kiowa for the shale beds. The name 
would no doubt have priority over the one herein used by me, but 
owing to doubt as to which subdivision Professor Cragin would
