the ears are wholly black behind, the ordinary dark cross on the shoul- 

 ders is present, and the tail tip is white. One skin has the greater por- 

 tion of the front of the fore limbs black ; in the other this part is rufous ; 

 in both specimens the underparts are grey. In the larger animal, 

 probably a male, the fur is much longer and softer, and the tail more 

 bushy than in the other ; and the claws, which in both are unusually large, 

 curved, and sharp-pointed, are more powerful. Both these skins can be 

 fairly matched in the large series of V. montana which I collected in 

 Gilgit, and to that species I accordingly refer them.
