ProsseR.|  Cretaceous.—Comanche Series of Kansas. 111 
Finally under the heading “Correlation” Professor Cragin reviews 
the facts at hand and concludes that “The evidence taken altogether 
seems to point to the conclusion that the Kiowa shales of Kansas, 
« * * represent a group of sediments intermediate between the 
Fredericksburg and Washita divisions [of the Comanche], and one 
which, as a meeting ground of the faunas of these two divisions, 
can not satisfactorily (though it may arbitrarily) be referred to 
either.’”! 
Haworth, 1896.—On Professor Haworth’s “Reconnaissance Geo- 
logical Map of Kansas’’ the geological formations south of the 
Arkansas river are represented more accurately than on any pre- 
vious map. In the eastern part of this region in Sedgwick and 
Sumner counties are Permian rocks west of which in Kingman, 
Harper, south Comanche and Clark are the Red-Beds, succeeding 
which is a band of Comanche extending from the northwest corner 
of Barber in an irregular southwesterly line across Comanche and 
Clark counties into the southeastern part of Meade county. The 
remainder of this area to the north of the Comanche and Red-Beds 
is mapped as of Tertiary age. 
CLASSIFICATION. 
In this Report all the Cretaceous deposits studied south of the 
Arkansas river, occurring in Barber, Kiowa, Comanche and Clark 
counties, except a few exposures of Dakota-like sandstone, will be 
referred to the Comanche series. As is well known, the extent 
and details of the most interesting formations composing this series 
in northern Texas were first accurately described by Professor Hill 
through whose enthusiasm and indefatigable efforts the series has 
since been traced far southward into Mexico. 
The writer considers that in Kansas the Comanche series is com- 
posed of two formations which may be readily distinguished by both 
their lithologic and paleontologic characters and may also be easily 
followed in the field for the purpose of areal representation.
