194 THE Ottawa NATURALIST. | | January 
Osborn and Dr. O. P. Hay, of the American Museum of Natural 
History, New York, who kindly lent the type of 7. vagans, the - 
writer was able to compare it with the Red Deer river material. 
This type consists of a small fragment, about two inches long, of 
a costal bone in which it would be difficult to point out any 
reliable differences between its surface sculpture and that of the 
Red Deer river specimens. The original description of the species 
by Cope is necessarily meagre. It does not seem to be so clear, 
therefore, as Mr. Hatcher’s remarks might lead readers of his 
report to suppose, wherein lie the differences between the Belly 
River form and Z7ionyx vagans from the Laramie. 
The types of Adocus lineolatus, Cope, were, according to 
Mr. Hatcher,7 ‘‘ almost surely secured from the Laramie.” They. 
are fragmentary as are also the specimens obtained from the Belly 
River formation in Canada by the writer who, in 1902, in Contri- 
butions to Canadian Paleontology referred them to Cope’s species. 
In comparing the types with the Canadian material the only 
character available is the surface sculpture in which there is so 
great a similarity that, for the present at least, it appears best to 
use the name of Cope’s species for the Canadian specimens, until 
other characters are obtained to prove or disprove the correctness 
of the present writer’s identification. 
The plastron of Bastlemys variolosus (Cope) is now well known 
from the material obtained by the writer, from the Belly River beds 
of Red Deer river, Alberta, and described and figured by him in 
1901* and 1902**. Cope’s description, based on material from 
Montana, was given in general terms, and published without 
figures, which may account for the slight notice that this large 
rugosely sculptured tortoise had apparently attracted. 
Baéna antiqua and Neurankylus eximius are two other species, 
from the Canadian west, described and figured by the writer in 
1902 (Contributions to Canadian Paleontology) from material 
secured on Red Deer river in the vicinity of Berry creek. Addi- 
+ Vertebrate Fauna of the Judith River beds, 1905.
