COLLECTION OF MAMMALS FROM TIBET. 801 



fulvous at its base, with a long, black, terminal portion. Underparts pure 

 white. 



The skull does not show any special characters by which it may be dis- 

 tinguished from that of the typical form. It is stout and well built, being 

 short and broad in the muzzle and rather swollen in front of the orbits, but 

 otherwise it shows no features of note. 



Dimensions of type (in flesh). Head and body 25 in,; tail 16 in.; hind foot 

 6 in. Height at shoulder 14*75 in. Weight 8 lbs. 



Skull. — Greatest length 145 mm.; zygomatic breadth 72 ; width in line with 

 ant. root of pm. 4, 37-5. (Further skull dimensions are given under the next 

 species.) 



Habitat.— Khumba Jong, Tibet, alt. 16,400'. 



Type.—B. M. 5, 4, 6, 1. Collected 8th October 1903, by Captain Walton. 



This race may be readily distinguished from V. v. flavescens by its much 

 brighter coloration throughout, and especially by the deep red median dorsal 

 area. In the true flavescens the back is much more uniform in colour, the 

 median dorsal area being but very slightly darker than the surrounding parts 

 and of a more brownish yellow, the red tint being entirely lacking. 



The local name is " Wamo." 



VULPES FERRIMTUS (HodgS.). 



Vulpes ferrilatus Hodgs. J. A. S. B., XI., p. 278, pi. ; Blanford, Faun. Br. 

 Ind., Mamm., p. 155 (1891) ; Mivart, Mon. Can., p. 121 (1890). 



a. Karo-La Pass, alt. 16,600', 30 miles E. of Gyangtse. 



The only specimen procured is a typical example of V. ferrilatus, but in 

 very bad fur. This species may always be recognized by the underfur, which, 

 besides being close and woolly, is fulvous to the base. The peculiar and 

 woolly character of the fur throughout is quite sufficient to distinguish i : 

 from all other species. 



Captain Walton writes : — " The small fox does not, I feel pretty sure, occur 

 near Khamba Jong, all the foxes seen there being of the large species (V. v. 

 waddelli, ante). I saw other foxes almost certainly of this species between 

 Karo-La and the neighbourhood of the Yan Dok Cho (Lake Palti)." 



Accompanying the skin is a very fine adult skull (text-fig. 52), which, so far 

 as I am aware, has never before been described. This skull is quite unlike 

 that of any other species of Fox, and is characterised by the extreme slender- 

 ness and elongation of the muzzle and the great length of the upper canines. 

 The brain-case and zygomata, on the other hand, do not show any signs of 

 lateral compression or elongation, but are fairly normal in their dimensions and 

 breadth. The supraorbital processes are stout and well developed, and the 

 brain-case gradually widens out from immediately behind these processes and 

 reaches its greatest breadth in line with the posterior roots of the zygomata. 

 On the under side we may note the narrowness of the soft palate and 

 the tendency of the pterygoids to approach each other posteriorly. The 

 bullae are more elongated and less rounded than usual. The dentition, which
