122 THE THIBET FOX. 



shows tluit it, like C.ferrilatus, is a short-eared form. The brush also 

 in both this and C. ecHoni is well developed, and the fur is long, 

 especially on the legs and feet. 

 Of the habits of this animal no records are known to us. 

 The coloration of the back and sides is of a pale or bright yellowish rusty. 

 The face and outside of the cars may be less yellow and more grey, or 

 may be rufous. The sides of the neck, breast, and i)ocly, and the greater 

 part of the tail have a mixture of black and white hairs, wiiich produces 

 a general tint of nearly pure grey. The tip of the tail is white, but 

 there may be a circle or dorsal patch of dark colour towards the root ; 

 the middle of the tail is for the most part grey. There is a faintly 

 marked dark stripe ruiming backwards from the eye, but no dark mark 

 between the eye and tlie nose. Tlic liml)s are yellowish rufous exter- 

 nally, whitish internally. Tlie lower parts are white, the middle of 

 the breast being strongly marked off by its whiteness from the dark 

 grey sides. 



This strong contrast between the grey and the white appears (from 

 the photograph) to be exaggerated in C. eckloni by a dark patch at the 

 ventral margin of the grey colour of the sides of the neck. 



The hairs of the back are light grey at the base, then rufous, and 

 finally black or white. 



The vibrissae are black. 



The fur on the legs and feet is rather long.

* According to Stoliczka (see Journal of the Asiatic Society of Bengal, vol. xxxvii. 

 part ii. p. 5) it is also found in the valley of the Upper Sutlej. It would be interesting 

 to have the statement confirmed.
