"The flat-topped hills, preferably isolated and sufficiently exten- 

 sive, either on the sun-parched maritime plain or high up on the Golis 

 range of mountains, six thousand feet above sea level, are its only 

 haunts in Somaliland. A coastal belt, probably not more than 

 seventy-five miles in width in any part of British Somaliland would, 

 I think, mark its range. . . . 



"They are usually seen in herds of four to seven individuals with 

 one or two adult males in the herd. I once found a herd of no less 

 than twelve." (Drake-Brockman, in Maydon, 1932, pp. 246-247.) 



"We found that two good places for Beira were: (1) the small 

 detached hills eight miles south of Sheik, not far from the wells at 

 Dubba, and on both sides of the Sheik-Burao road; (2) the long, 

 flat-topped hills immediately west of and above Lafarug on the 

 Berbera-Hargeisa road thirty miles from Berbera. . . . 



"They are generally seen in pairs or threes on bare, stony hill- 

 sides. . . . We never found more than one herd on one small hill."
