found in the same horizon a considerable distance away. Fu- 
sulinella? sp. is quite common locally at Kansas City and want- 
ing at Erie. Chonetes verneuilanus N. and P. is much more 
abundant at Kansas City than at Erie, as is Dielasma bovidens 
Mort. and Axophyllum rude W. and St. J. Marginifera lon- 
gispinus (Sow.?) is moderately abundant at Kansas City and 
extremely so at Erie. Fifty-seven of the species recorded 
from this horizon are not common to the two localities. The 
whole pelecypod and cephalopod fauna is wanting at Kansas 
City, as are most of the gastropods. Molluscs and corals seem 
to abound in the southern locality and not in the northern. 
In the Mound Valley limestone five of the species of impor- 
tance at Erie are wanting at Kansas City. They are Myalina 
subquadrata Shum., Polypora elliptica Rog., Stenopora car- 
bonaria (Worth.), Productus pertenuis Meek, and P. cora 
d’Orb. This horizon does not appear to be very fossiliferous 
at Kansas City, but fourteen species being found there, while 
three times as many occur in it near Erie. 
The fauna recorded from the Galesburg shales is from Kan- 
sas City. 
The Dennis limestone has a very different appearance at 
Kansas City from what it has on the Neosho river. At the 
former locality it is dark and cherty, while in the southern 
region it is very light colored and sometimes slightly odlitic. 
The faunal differences are quite as great as the lithologic char- 
acters. Of the sixteen species of numerical importance from 
this formation only six occur at Kansas City. Two of these 
are not found on the Neosho river—Schizodus wheeleri 
Swall., and Bellerophon percarinatus Conrad. The remaining 
ten are mostly brachiopods, largely Producti. They are Squa- 
mularia perplexa (McChes.), Productus punctatus Mart., P. 
pertenuis Meek, P. costatus Sow., Proboscidella sp. and Spirifer 
cameratus Mort., and three Bryozoa, Stenopora carbonaria 
(Worthen), Rhombopora sp., and Cystodicta inequimarginata. 
Rog. Of the whole fauna of this limestone only about twenty 
per cent. (seventeen species) of them are common to the two 
regions. The coralline fauna, together with nearly all the 
Bryozoa, fourteen species of brachiopods, twelve species of 
pelecypods, four gastropods and a cephalopod, are confined to 
the southern region, while one bryozoan, three brachiopods, 
twenty-two pelecypods, three gastropods and ten cephalopods 
are known only from Kansas City. It will be seen that the
