F.—CLIFTON’S BIGHORN (O. canadensis borealis). 
An East Siberian race closely allied to the last, but of a generally 
lighter colour, with a much larger and less well-defined white rump- 
patch, more white on the face, a darker tail, and larger ears. 
Distribution—The Stanovoi Mountains, the range between the valleys 
of the Yana and Lena, and other parts of Eastern Siberia. 
The 
only known examples in England were shot by Mr. J. Talbot 
Clifton, by whom a male was presented to the British Museum in 
1902.
