and would not be mentioned in the present 
connection if it were not for the necessity of 
showing that the correlation of the Texas 
Comanche series with the Lower Cretaceous 
of Europe is incorrect and can not hope to. be 
ultimately accepted, and because this problem 
is so intimately bound up with the age of the 
Cheyenne sandstone. 
If there is no marine Lower Cretaceous in 
Kansas, as I contend, our ideas of the sequence 
of events from late Lower Cretaceous time into 
the Upper Cretaceous require to be very greatly | 
modified. 
With regard to Twenhofel’s proposal to refer 
the Mentor and Dakota of central Kansas to 
the Comanche, all that I can say is that while 
he and before him Cragin and others have 
written about the Dakota flora, this term is 
altogether meaningless stratigraphically, ex- 
cept that it denotes in a most general way a 
change in facies between’ Lower and Upper 
Cretaceous floras. The flora of the Cheyenne 
sandstone, and I presume that in the Mentor 
formation as well, is no more like that of the 
Woodbine sand than the Woodbine flora is like 
that of the several formations of the Montana 
group, and the reference of the Dakota sand- 
stone—that is, the post-Mentor Dakota sand- 
stone ot central Kansas—to the Lower Cre- 
taceous if correct would of necessity carry 
with it the Bingen sand of Arkansas, the Tus- 
caloosa formation of Alabama, the Black Creek 
formation of the Carolinas, and the Magothy 
formation of New Jersey and Maryland, against 
whose correlation with the Senonian of Europe 
by paleozoologists I have been arguing for 
years, with not very great success. 
LOCALITIES. 
All the localities from which fossil plants 
were collected in the Cheyenne sandstone are 
in the immediate vicinity, of Belvidere, Kiowa 
County, Kans. (See Pl. XLVI.) I give be- 
low a transcription of the locality numbers, 
with the names of the collectors and dates, 
taken from the United States Geological Sur- 
vey’s records. There appears to be some con- 
fusion in the two collections numbered 2224, 
nor do I have locality numbers for the material 
collected by Ward and Vaughan in 1896. 
These defects in the record are immaterial, 
however, for there is no doubt that all the ma- 
terial studied came from the Cheyenne sand-

numbers are duplications of identical outcrops 
and are given only as a matter of record.

CHARACTER OF THE FLORA. 
The flora of the Cheyenne sandstone as dis- 
closed in the present study numbers. but 23 
species. It comprises four ferns representing 
the families Polypodiaceae and Gleicheniaceae, 
and all four are representatives of widely
