Prosspr.|  Cretaceous.—Comanche Series of Kansas. 105 
description of certain “New and Little Known Invertebrata from 
the Neocomian of Kansas.”! The invertebrates described in this 
paper were collected in Kiowa and Clark counties. In connection 
with the description of these species are notes explanatory of the 
typical sections of this formation. The geological systems covering 
Kkansas south of the Arkansas river as represented on McGee’s 
reconnaissance map of the United States,’ are the Cretaceous Jura- 
Trias and Neocene. ( 
Cragin and Hill, 1895.—Professor Cragin published further “De- 
scriptions of Invertebrate Fossils from the Comanche Series in 
Texas, Kansas and Indian Territory? which was followed by another 
article entitled “Vertebrata from the Neocomian of Kansas.’* In 
this paper Professor Cragin names the fossiliferous shales overlying 
the Cheyenne in Kiowa county, his definition being as follows: ‘‘The 
designation, Kiowa shaies, is proposed for the inferiorly dark- 
colored and superiorly hght-colored shales that outcrop in several 
of the counties of southwestern Kansas, resting upon the Cheyenne 
sandstone in their eastern and upon the ‘Red-Beds’ in their middle 
and western exposures, and being overlaid by brown sandstones 
of middle Cretaceous age, or Tertiary or Pleistocene deposits ac- 
cording to their locality. 
“he Kiowa shales are a locally modified southern extension of 
part of Hill’s Comanche series, cut off from the main part by erosion. 
They are named from the place of their typical occurrence, Kiowa 
county, Kansas; and in that county they outcrop only in those 
southern townships which once formed the northern part of 
Comanche county. The fossils of these shales are chiefly those 
which, in Texas, are most common in the Fredericksburg division 
[Comanche series].”” In June of this year Prof. Hill first an- 
nounced the ‘Discovery of a typical dicotyledonous flora in the 
Cheyenne sandstone’ * * * “This sandstone has heretofore 
been referred to the Trinity Division of Texas by Prof. F. W. Cragin,
