336 Description of a new species of Tibetan Antelope. [No. 173. 



at all, noticeable in the mature animal. The horns are equally rounded 

 to the front and back, compressed considerably on the sides, so that 

 their basal outline is elliptic, and the compression and annulation extend 

 to within one and a half inch of the tips. In a very perfect specimen 

 now before me, there are twenty-seven rings, which go entirely round the 

 horns, each ring being separate and distinct, and the longitudinal stria- 

 tum too faint to impair the continuity of the annulation. In the 

 younger specimen, the compression of the horns is very trifling, and the 

 rings, larger in front than elsewhere, are only six or seven in number ; 

 the animal being rather more than a year old. To proceed with the 

 description of the mature male of the species, I may next note that the 

 neck is rather thin, the body short and compact, the limbs long and ex- 

 quisitely fine, the low hoofs compressed anteriorly, wide and rounded 

 posteriorly, and that the false hoofs are large, but obtuse and adpressed. 

 The tail is a mere rudiment, depressed, broad, triangular, entirely nude 

 below, and furnished with radiating hairs, about one and a half inch 

 long, on the sides and tip. The pelage or fur offers no peculiarity, con- 

 sisting of hair only, neither fine nor very coarse, and of equable length of 

 about one and a half inch. The scull presents the Cervine and Antelopine, 

 not the Ovine and Caprine* form. There is no trace of suborbital, 

 of superorbital, of maxillary glands or pores, nor of moist muzzle, 

 nor of inguinal pores ; and the interdigital pores, though distinct, are 

 small. The females are hornless, and have only two teats, which are 

 perfectly developed in the males also. There are no tufts to the knees, 

 nor any of those marks upon the face, flanks, and limbs, which are so 

 frequent among the antelopes. In regard to colour, my two specimens, 

 which were brought here in November, and killed, no doubt, in summer, 

 exhibit above and laterally, a dull and somewhat purpurescent-brown, 

 freckled with hoary, owing to the pale fawn tips of the hairs, and below 

 rufescent- white, which colour likewise is extended all over the limbs, 

 over the insides of the ears, the back parts of the head (in the old ani- 

 mal), and the posteal margin of the buttocks, whence it spreads like a 

 small disc round the tail, becoming also more rufous there ; and thus the 

 tail, which is black itself, assumes that contrast of colours that has sug- 

 gested the specific name — Picticaudata. Dr. Campbell's specimen of a 

 female is paler in colours than my males, the superior surface being 

 hoary-blue or canescent- slaty ; and as such, is the winter hue of so many 

 other Tibetan ruminants ; it is probably also that of the G6a. I have 

 said that the limbs are entirely colourless ; but there is, especially in
