320 CAPT. H. G. C. SWAYNE ON THE [Apr. 3> 



where it overlaps with the range of the Gol-ass. The female 

 Gussuli appear to be much larger than the male ; and it is a 

 pretty safe rule, when looking for a buck, to fire at the smaller one. 

 The Gussuli have long snouts, in shape quite different from 

 that of the Gol-ass, being much longer and tapering to a point. 

 Thev are also somewhat larger than the Gol-ass, and are recognizable 

 in the bush by their grey colour. They start up in pairs or in 

 threes. Sometimes the bush is alive with them, and I have seen 

 more than a dozen run off together; but they do so only when 

 alarmed, and are not naturally gregarious. 



The Beiba Antelope (see P. Z. S. 1892, p. 308). 



" I first heard of the ' Beira ' near Ali-Maan, in the Gadabursi 

 country, among very rugged hills, in the autumn of 1891. Then 

 my brother fCapt. E. Swayne, Bengal Staff Corps) saw two for 

 the first time, but failed to get a shot. 



"He described them as reddish Antelopes, rather larger than the 

 Klipspringer, with small straight horns, bounding away among the 

 rocks exactly as a Klipspringer does. 



" On my last trip the Somalia assured me that 1 should find 

 ' Beira' on the Wagar Mountain and on Xegegr, which is its eastern 

 continuation, is about 40 miles S.S.E. of Berbera, and rises to 

 nearly 7000 feet. They said it was nearly as large as an ordinary 

 flabby-nosed Gazelle, but reddish — that it inhabited ground similar 

 to the Klipspringer, but was shy and difficult to shoot. This no 

 doubt accounts for no European having shot one, though my 

 brother heard of them so far back as 1891. 



" I tried vainly to get ' Beira,' having no time to go again to 

 Wagar myself. On leaving the coast last November, I sent men 

 in to look for 'Beira,' offering a reward of 20 rs. for a good head 

 and skin of a male and female, and gave full instructions to my 

 agents in Berbera and Aden to pay the reward and to send me the 

 specimens. I received the two skins and pair of horns direct 

 from Aden, without explanation, but have no doubt whatever they 

 are the specimens of ' Beira ' which I sought. They have 

 evidently been killed by natives, and that accounts for the imper- 

 fect condition of the specimens. To my brother is due the credit 

 of the discovery.'' ' 



Grevy's Zebra (JSquus grevyx). Somali name "Fet^o? 



Grevy's Zebra was, 1 think, first shot in Somalilaud by Colonel 

 Paget and myself on our simultaneous expeditions last spring. 



1 found them first at Durhi, in Central Ogaden, between the 

 Tug Fafan and the Webbe, about 300 miles inland from Berbera. 

 I shot seven specimens, all of which were eaten by myself and my 



1 [Since this paper was read the " Beira " has been described by Herr 

 Menges (Zool. Anz. xvii. (1894) p. 180) as a new species, and called Oreotragus 

 megatott8.—P. L. 8.]
