Nine specimens, collected as follows: Shesley Mountains, 

 3, August 24; Iskoot Summit, 6, October 4-10. They are 

 mostly young adults, but include one quite young lamb, three 

 old females, and a three-year-old male. The flesh measure- 

 ments of the three adult females are: Total length, 1359

 year-old male: Total length, 1283; tail vertebrae, 127; hind 

 foot, 406; height at shoulders, 902. A female lamb in the 

 soft first pelage: Total length, 759; tail vertebras, 76; hind 

 foot, 279; height at shoulders, 559. The largest of these three 

 females is very old, with worn-out teeth; the others are fully 

 adult.

 black stripe runs from the dark area of the back to the tail, 

 dividing the white rump patch .into two halves. This feature
