302 THE SHEEP AND ITS COUSINS 



tainly absent, and the same appears to be the case 

 with interdigital foot-glands.^ In the bharal the 

 face-glands are likewise lacking, while the foot- 

 glands are represented, at most, by insignificant 

 vestiges ; the whole structure of the foot being, 

 indeed, essentially that of a goat. In fact, although 

 the rams lack a "goaty" odour and a beard on the 

 chin, the bharal comes in many respects decidedly 

 nearer to Pallas's tur than it does to the typical 

 sheep. 



The heavy fringe of long hair clothing the 

 throat, neck, and fore-quarters, and the great 

 relative length of the tail, serve at once to dis- 

 tinguish the North African arui, udad, or Barbary 

 sheep {Ammotragus lervia, or A. tragelaphus) from 

 all other wild sheep. The horns of the rams are of 

 the same general type as those of the bharal, but 

 show a distinctive kind of transverse wrinkling when 

 young and unworn ; those of ewes being only slightly 

 smaller. In correlation with the lack of face-glands, 

 the skull has no suborbital pits. 



The arui is a large sheep, standing about 39 

 inches at the shoulder, and falling away towards the 

 croup. Its whole make is distinctly heavy and un- 

 gainly ; the head being relatively long and somewhat 

 donkey-like, with, for a wild sheep, rather large 

 ears. From the nape of the neck to some distance 

 behind the withers runs a short " hogged " mane ;
