Series in Kansas, Oklahoma and New Mexico. 223 
burg. According to the fauna as identified by him and as 
analyzed above, they could more logically have been referred 
to the uppermost Upper Cretaceous (the Montana division) 
than to the Fredericksburg, since the list contains more Ripley- 
Montana than Fredericksburg species. But the Washita 
species as enumerated by him far exceed those from all other 
divisions, and hence upon his own data the beds should have 
been chiefly referred to this division. 
Concerning the alleged Ripley, Montana, Colorado and 
Dakota species mentioned by Prof. Cragin, it is strange that 
none of them were found in the collections studied by Mr. 
Stanton, and we cannot escape the conclusion that they were 
founded upon erroneous identifications. 
Mr. Stanton’s studies of the fossils of the Belvidere shales 
also demonstrate the opinion I have long entertained, that 
these fossils are largely of the age of the Washita division of 
my Texas section, and not solely the Fredericksburg and 
Trinity divisions, as maintained by Cragin. I am glad to 
have my own conclusions sustained by such an authority, and 
I fully agree with him that the Belvidere beds represent in 
general the Washita division and probably the attenuated 
Fredericksburg as seen in the North Texas section. 
There are several points more strongly suggesting this 
affinity than Mr. Stanton has brought out. Mr. Stanton’s 
diagnosis removes the alleged O. franklini from the list of 
Kansas species, while Prof. Cragin himself has retracted the 
other Trinity species (Cucullwa terminalis Conrad) which he 
once reported.* The facts eliminate the sole molluscan species 
upon which Prof. Cragin could correlate these formations with 
the Trinity division of Texas. 
Mr. Stanton also finds in the Belvidere shales two additional 
species which Cragin himself has recently described from 
Texas, to wit: Avicula leveretti,t of the Washita of Denton 
county, Texas, and the peculiar Znoceramus to which I have 
called attention in previous writings, as being found only 
in the Preston beds,t and to which Prof. Cragin has re- 
cently given the name J. comancheana.§ Thus we have 
common to the Belvidere beds of Kansas and the Preston beds 
of the Washita division of Texas and Indian Territory the 
following peculiar species which occur in no other geologic 
horizon, and seem to intimately connect these beds at the two 
localities :
