Mr. Stanton, whose lists are given accompanied by critical dis- 
cussion of certain species. Following this is an analysis by Professor 
Hill stating from what other formations they have been identified. 
As a result of this study Mr. Hill concludes “Mr. Stanton’s studies 
of the fossils of the Belvidere shales also demonstrate the opinions 
I have long entertained, that these fossils are largely of the age of 
the Washita division of my Texas section, and not solely the Fred- 
ericksburg 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 Fred- 
ericksburg as seen in the north Texas sections.’ 
In reference to the correlation of the Cheyenne, Professor Hill 
says: “Prof. iXnowlton’s determination of the dicotyledonous Dakota 
flora in the top of the Cheyenne sandstone shows that from a 
paleontologic standpoint these sandstones have no resemblance to 
the flora of the Trinity divisions at Glen Rose, Texas, beds which 
eontains a flora of typical Potomac non-dicotyledonous species. 
The Cheyenne sandstones are of far later age than the Trinity, and 
occupy a stratigraphic position at the base of the Washita midway 
between the Trinity and Dakota. * * *. Concerning the corre- 
lations of the Belvidere beds with the Neocomian, as done by 
Professor Cragin, we can only repeat our opinion, founded upon 
facts previously given, that the Washita division is homotaxially 
nearer the equivalent of the Gault, and that the lower lying beds 
of the Trinity divisions are more nearly the nearer equivalents of 
the Neocomian in the United States.’? Professor Hill’s final state- 
ment is “These beds represent the modified attenuated ‘northern 
extension oi the Washita division and probably a portion of the 
Fredericksburg division of the Comanche series of Texas, which 
as we have previously shown, far overlapped to the northward 
those of the Trinity division.’”? 
The previous paper was followed in three months by Professor 
Cragin’s, entitled “A Study of the Belvidere Beds.’* Professor
