THE MHORR GAZELLE 51 



exceedingly rare not only in zoological gardens 

 but even in museums, where skins and heads of 

 animals can be so readily stored that even rare 

 forms may at last become well represented by the 

 gradual accumulation of chance specimens. The 

 relationship of the mhorr to other gazelles is a 

 very interesting theme which although it has 

 received considerable attention from naturalists is 

 not yet fully elucidated. Three large forms of 

 gazelle exist in North and West Africa, all 

 evidently closely connected, and in their long 

 necks and legs showing considerable affinity with 

 the curious gazelle-like antelopes (gerenuk and 

 dibatag) which inhabit Somaliland. The three 

 forms are ( i ) the mhorr gazelle already described : 

 (2) the dama gazelle inhabiting Senegal and 

 Gambia : and (3) the red-necked or addra gazelle 

 of Dong^ola and Sennaar. These three animals 

 may eventually be found to be more akin than 

 is at present admitted by naturalists : a few words 

 may here be devoted to this matter. 



The dama {Gazella dama) is a fine species so 

 closely resembling the mhorr as to be practically 

 identical with it. The only remarkable difference 

 between the two is that in the dama the white of 

 the abdomen and rump coalesce to separate the 

 rufous hue of the hind legs from that of the body. 

 Some naturalists have indeed united the two 

 forms. The splendid menagerie which Lord
