GREVY S ZEBRA 



especially noticeable in the topi. I shot several speci- 

 mens of the latter, but although the length of horns in 

 some cases reached over 19 inches, their basal girth 

 was insignificant compared with those I had seen from 

 the Loita Plains farther west. 



The southern form of Grevy's zebra {E. grevyi) 

 is met with throughout the Lorian district and 

 northern Jubaland, the stripes being pure black on 

 a white ground. It would be interesting to know 

 where this race changes into the Somaliland Grevy's 

 zebra {^E. grevyi be^^berensis), of which there is an 

 excellent specimen in the British Museum, whose 

 stripes are a deep rich brown on a cream ground. I 

 was very much surprised to see it stated, the other 

 day, in an article on northern Jubaland, that these 

 zebra are generally to be found in waterless regions. 

 This is the opposite of what my observations had led 

 me to believe, and I think that the majority of those 

 who have had the opportunity of closely observing 

 its habits will agree with me in saying that though it 

 is sometimes met with in semi-arid districts, there is 

 generally water somewhere near, and that it drinks, 

 if not every day, at any rate every second or third 

 day. In the interior of southern Jubaland, where 

 desert conditions attain their maximum development, 

 zebra are totally absent, but on the Dibayu Plain, 

 and southwards through Joreh, there are a certain 

 number of a much smaller species of zebra closely 

 akin to those found on the Athi Plains {^E. burchelli 

 granti). There are, however, important differences 

 between these two races, which I have attempted to 

 set forth in the following table, since the specimen I 

 obtained appears to be a new race, and its comparison 

 with Grant's zebra may therefore be of interest.
