It was included by Cope in his list of Judith River vertebrates. Barnum 
Brown found what appears to be the same species in the Hell Creek beds. 
Compsemys victa Leidy was described from the beds of Long Lake. 
Its sculpture is characteristic, resembling small, closely placed, pustules, 
that cover all parts of the shell, and appearing in no other turtles. It is 
fragmentary, but very common in the Lance Creek beds. Barnum Brown 
has collected it in the Hell Creek deposits. Cope included it in his list 
of Judith River vertebrates. He also found it in Colorado, in deposits 
that belong to either the Arapahoe or the Denver. I am able to say that 
the same genus is represented by an undescribed species in the Fort Unicn. 
Aspideretes foveatus (Leidy) was described from the Judith River 
basin. Leidy had other specimens from Long Lake, N. Dakota. There 
are many fragments of the species in a collection made in the Judith Basin 
for Cope by Charles Sternberg. A nearly complete carapace was found in 
the Belly River beds by Lambe. Fragments indistinguishable from the 
type were secured by Barnum Brown in the Hell Creek region. The cara- 
pace is ornamented by a characteristic pitting. 
Aspideretes beecheri Hay has for its type a specimen in Yale Uni- 
versity which lacks little more than the head and a part of the neck. Mr. 
Hatcher collected in the Judith River beds two quite complete carapaces 
which I have examined, without being able to distinguish them from the 
type of A. beecheri. 
Adocus lineolatus Cope is a turtle that is not well known, but 
fragments of what appear to be the same species are not uncommon. The 
sculpturing is peculiar. The type was found in Colorado, in probably the 
Arapahoe formation. Cope included it among the vertebrates of the Judith 
basin, and Lambe reported it from Belly River deposits in Alberta. Bar- 
num Brown found in the Hell Creek beds what seems to be the same 
species. 
The genus Basilemys is represented by turtles of large size and an ex- 
traordinary form of sculpture. The type B. variolosa (Cope) has as its 
type a large part of the plastron and considerable parts of the carapace. 
This type was found in the Judith River basin. Members of the Canadian 
Geological Survey found good specimens of the species in the Belly River 
beds in British America. A second species of the genus has been dis- 
covered in beds of the Lance Creek epoch, in Custer County, Montana. 
The type is a compiete shell. Had only fragments been found that did not
