1857.] On a new species of Lag omys. 207 



On a new Lagomys and a new Mustela inhabiting the north region 

 of Si/cim and the proximate parts of Tibet. — By B. H. Hodgson, 

 Esq., B. C. S. 



I have just obtained from the northern region of the Sikiin Hi- 

 malaya and the proximate part of Tibet some fine Mammal spe- 

 cimens, among which are two species which seem to me new, and the 

 rather in that I have several samples of each species in very fine 

 condition inclusive of the sculls. I subjoin a summary description 

 of both. 



Mustela Ternon, nob. 

 Temon of the Tibetans. 

 This species is 9^ inches long from snout to vent and the tail is 

 6| more. Its fur is short, soft and straight, being scarcely longer 

 on the tail than on the body. The colour is, above and laterally, 

 with the entire tail, brunnescent fawn ; below, entirely pale pure 

 yellow save the head and margin of the upper lip, which, as well as 

 the limbs, are canescent ; the last, however, with more or less of a 

 brownish tint to the front or externally. The tail is f the length of 

 the animal. The fur is f of an inch long and very fiue. The di- 

 mensions are as follows : 



Snout to vent, t 9 \ 



Head, 2 



Tailandhair, 6 \ 



Tail less hair, 5 \ 



Ears, f

Lagomys Curzonise, nob. 



Abra of the Tibetans. 



My specimens were procured in the district of Chumbi. They 



are three in number and in fine preservation and high state of fur. 



Tbey are quite alike in size and colour and demonstrably mature 



from the state of the teeth, They measure 7J inches from suout
