Remarks.— -To Dr. CampbelPs kind arrangements I am 

 indebted for a fine specimen of the wolf of Tibet, with the 

 scull complete. It was a female and aged, as is proved 

 by the obliteration of the sutures of the scull and by the 

 worn state of the teeth. Eight teats only are traceable. 

 No European, Asiatic, or American wolf that I am acquainted 

 with, has the frontal sinuses so amply developed on the brows, 

 consequently, so elevated as this species, whose scull bears 

 a great resemblance to that of the Cabul greyhound. Not- 

 withstanding the size of the longitudinal and transverse 

 cristse, the walls of the encephalon have a considerable swell, 

 leaving ample space for a good-sized brain ; and the elongation 

 of the face, that is so noticeable in the head with its integu- 

 ments, is by no means equally striking in the nude scull, 

 so that a good deal of it must be ascribed to ample develop- 

 ment of the cartilaginous part of the nose, a feature which, 

 added to the unusual size of the frontal sinuses, would seem 

 to indicate considerable powers of scent in the living animal. 

 There are no wolves in the Sub-Himalayas. In the plains 

 of India, as of Tibet, they abound : but the species proper 

 to the plains of India is very different from that proper to the 

 plains of Tibet above described. Throughout India and 

 its vicinity, wolves appear absolutely to eschew the mountains, 

 and so also, generally speaking, do jackals and foxes.* These 



* Pearson's vulpes montanus, confined to the vicinity of the snows, is an 

 exception rather proving than disproving the rule. It is commoner in the 

 plains of Tibet than in the Himalaya.
