strikingly resemble those described by Williston and Cragin 
from the Belvidere beds of Kansas with the execption of two 
species of Pycnodont fishes belonging to the genera Uranoplosus 
and Coelodus, for which this is a new horizon”; while the inverte- 
brate fossils served as a basis for correlating them with the typical 
Texan formations and Professor Hill further says: “From the 
Molluscan species it will be seen that these beds paleontologically 
‘more resemble the Washita division than the Fredericksburg. 
Furthermore they show the same general association of Molluscan 
species as do the Belvidere shales, and like them differ from the 
beds of the Central Texas region by containing vertebrates. That 
they are a southern extension of the Belvidere beds there can be no 
reasonable doubt.’! 
Another area containing the same invertebrate fossils was de- 
scribed by Professor Cope, at a point about twelve miles south of 
Fort Supply and south of the North Fork of the Canadian.” 
Much farther to the southeast on the southern side of the 
Canadian river, in county G of Oklahoma territory ‘according to 
Professor Hill, is the Comet creek area of Cretaceous discovered by 
Prof. Jules Marcou who briefly described it as “the remains of beds 
of a limestone filled with shells, which I connect with the Neocomian 
of Europe; or in other words, with the Lower Division of the 
Cretaceous rocks.’* In reference to this remnant of the Cretaceous, 
Professor Hill concluded that “Inasmuch as these beds lie in the 
Kansas province, i.e., the region north of the Ouachita system of 
mountains, and is completely cut off from the Texas region by 
them, it is reasonable to infer, until the localities can be visited, 
that the Comet creek bed is a part of the same general formation 
as those near by at Camp Supply and Belvidere.’ 
Hinally, the thorough survey that Professor Hill is now making 
of the Territory under the auspices of the U. S. Geological Survey 
will undoubtedly furnish complete information in reference to the 
geology of this interesting region. Asa part of that work, the boun-
