Third Journey to Thibet, p. 216. 



Two specimens, from Thibet, are preserved in our National Collection, 

 and one of them (a type of the species) is figured in our accompanying 

 Plate XXVIII. It is not without some doubt and hesitation that we 

 present this as a really distinct species, thinking it far from impossible 

 that it may be but a local variety of C'a//is corsac. 



One distinction consists in the white tip to the tail of C. ferrilatus, 

 whereas that of C. corsac is black. We have, however, already recorded 

 instances which show that this character cannot be relied on as an 

 absolutely constant one. ]\Iuch more important is the distinction 

 asserted to exist in the length of the ears ; for C. corsac is rather a 

 long-eared dog, while C. ferrilalus has the ears decidedly short. It is 

 this circumstance, together with the fact that it is a native of Thibet, 

 which leads us strongly to suspect that the newly-described species 

 C. eckloni of Prejevalski, which is also a Thibetan animal, may really 

 be nothing but Vidjjcs ferrilatus of Hodgson and of Blanford. 



Until the detailed description of the animal appears this (jucstion 

 must remain undecided, but the photograph already published plainly
