Kamschatkan Bighorn 223 



extending from the dark of the back through the caudal disk to the tail ; 

 upper and under lip grayish-white ; caudal disk, middle of under-parts, 

 and a narrow line down the hinder surface of each leg white, there being 

 also some white on the lower part of the inner surface of the metatarsal 

 segment of the hind-legs. The white on the under-parts and posterior 

 surface of the legs is tairly well defined from the adjacent brown areas, 

 hut not so sharply as in /iiirJcnsis, the amount of white on the limbs 

 being much less than in the two preceding races. In winter apparently 

 turning white, either in some districts or invariably. A full-grown ram 

 in good condition will weigh about i^i^o lbs.

Not having had the opportunity of seeing skulls of the three northern 

 races of American bighorns, I am unable to say how far these differ from 

 that of the present form. The race is, however, sufficiently characterised 

 by the absence of a mane on the nape of the neck, the long and woolly 

 hair, the small size of the white caudal disk, the great width of the 

 median dark streak by which it is traversed, and the narrowness of the 

 white area on the legs. 



At the present time the British Museum possesses the mounted skin 

 of an immature male, which from the great length of the hair is evidently
