36^ IMr. O. Tliomas on a neto Goat. 



the lergtliened liairs of the mane bvoaclly tipper! with black ; 

 upper surface of muzzle, sides of chin, and tail deep black, 

 blackish markinj^s also present on cheeks, bank of ears, and 

 on metacarpo- (and tarso-) phalangeal joints. Elsewhere 

 the limbs are pale-coloured, while the belly is nearly white. 

 Chest with a naked glandular patch. Knees naked and 

 callous. No interdigital glands. Mammae 2 *, as in Capra 

 and in Hemitragus hylocrius. 



Skull showing a closer relationship to that of 11. jemlaicus 

 than to that of II. hylocrius^ but readily distinguished from it 

 by its much smaller size, narrower and more convex forehead, 

 broader and shorter nasals, which are expanded posteriorly so 

 as to nearly fill up the prefrontal vacuities, and by the 

 different direction of the parietal plane, which slants upwards 

 at an angle of 45° instead of being nearly vertical. 



Horns approximately of the same form and direction as 

 those of H. jemlaicus^ but rather longer in proportion, far 

 slenderer (their basal circumference only 137 millim., as 

 against 230 millim., both old males), and their surface, espe- 

 cially along the anterior angular ridge, smoother and less 

 nodulose. 



Dimensions of the type (B. M. 94, 3. 9. 11), an old male, 

 measured in skin : — 



Snout to root of tail (approximate) 1100 millim., tail about 

 25 or 30 ; hind foot, from heel to base of hoof, 191 ; ear 

 from notch (measured when moistened) 100, its breadth 53. 



Skull: gnathion to occiput 218; greatest breadth 109; 

 nasals, length 61, greatest breadth 27 ; gnathion to orbit 133 ; 

 forehead, breadth outside bases of horns 61 ; palate-length 113 ; 

 length of upper molar scries 59. 



Horn : length round curve 295 ; greatest basal diameter 

 59, least ditto 29. 



Hal. Jebel Tawf, S.E. Arabia. 



Two adult male specimens of this striking novelty were 

 collected by Dr. A. S. G. Jayakar on Nov. 7, 1892, and 

 have been presented by him with a set of other mammals to 

 the British Museum. 



* At least in the male. 



t I cannot iind this mountain in any map available to me ; but it is 

 probably one of tlie constituent parts of the .Icbel Aklidar ntugo, just 

 behind Muscat, -which attains an altitude of nearly 10,000 feet.
