Stages A and B correspond with similar divisions proposed 
by Professor Haworth,?"4 based upon lithologic and topo- 
graphic features. The Pottawatomie formation there de- 
scribed falls into Stages C, D, E and part of F. The Douglas 
is represented by the upper part of Stage F, the Shawnee by 
Stage G and the basal part of H. The Wabaunsee Stage is 
largely represented in Stage H, which should retain the name 
Wabaunsee, in the opinion of one of the writers. The re- 
mainder of the stage is found in Stage I. The three upper 
formations are grouped under Stage J, which is exactly equiva- 
lent to Prosser’s Council Grove Stage, which should stand. 
In the “Bulletin on the Economic Geology of the Indepen- 
dence Quadrangle,” the United States Survey proposes a series 
of overlapping or interlocking formations which include parts 
of each other in a confusing way. Some of the limestones 
play out, one here and another there, in the southern part of 
the state. Where a limestone disappears the overlying shale 
and the underlying shale are grouped together under a forma- 
tion name. Another one next to these disappears later and the 
three shales are given a third term. This seems to have been 
the general scheme followed, and the result is shown in the 
left column in the last tabulation. 
It will be noted that there is a general correspondence be- 
tween Series I, II and III and the old classification of Lower, 
Middle and Upper Coal Measures, though there is no inclina- 
tion on the part of the writers to make such a substitution. 
SERIES I. 
The first grand division of the Coal Measures rocks with re- 
spect to the enclosed fossils extends from the base of the 
Cherokee shales to the base of the Bethany Falls limestone. 
There are at least twelve species which are at present unknown 
outside these rocks in the Kansas section, though some of them 
appear to have greater range in other regions. They include 
five cephalopods; Asymptoseras newloni Hyatt, Domatoceras 
umbilicatum Hyatt, Temnocheilus crassus Hyatt, T. depres- 
sus Hyatt, and 7. latus Hyatt; one gastropod, Aclisina mi- 
nuta Stev.; one pelecypod, Conocardium acadianum Dawson; 
two brachiopods, Chonetes mesolobus N. and P., and a species 
of Seminula. Species of the genus Prismopora are unknown 
except in these rocks. Aside from these our collections do
