you reach the region of the Haud. On the great prairies of the Haud I have seen an 
astonishing number of great herds from a single point of view. When travelling with 
Mr, E. N. Buxton and Mr. A. E. Leatham we first came on to the great Marar Prairie 
these Gazelles were seen in incredible quantities, and not having been hunted by even 
the Midgans (who devoted their time to pursuing the Oryx with their dogs and poisoned 
arrows) I found them astonishingly tame, so much so that after securing two or three 
specimens I never had the heart to betray their confidence, and have often walked past 
them in the thin bush that lines the northern edge of the plain within 20 paces, and 
on some occasions so near that I could almost have touched them with a long stick. At 
such times they have just lifted their heads till I had passed, and on looking back 
they had resumed feeding within a minute. I mention this as it is so very much in 
contrast with my experience when crossing the Toyoo Plain to the east in December 
1896, when, though there were vast numbers of them, they were most extraordinarily 
wild and went off full gallop if you came within 400 yards of them. This was no doubt 
the result of having been shot at by English shikaris, who often take this route into 
Ogaden. On the Ogaden side of the Haud we found them frequently both in the long 
dhur grass, the home of the Dibatag (Ammodorcas clarkei), and also in open glades in 
the regular bush. When we were west of Milmil we came across these Gazelles 
occasionally till we reached the neighbourhood of the Tug Sulul; but I do not remember 
seeing them again in the more broken country that les west of this Tug, and which 
continues practically hilly right up to the mountains of Bourka. From what I have 
heen able to observe of the habits of this Antelope, I should think the traveller might 
expect to find it m any part of this corner of Africa where there are grass plains or 
where the bush is level and not too thick. It seems to thrive as well at sea-level as on 
the Haud at an elevation of 5000 feet. 
“Tn the larger herds (say from 40 to 150 or more) the sexes are generally mixed, 
with a large preponderance of females. Some large herds are all females. Small herds 
may be either mixed, or all females, or all bucks. I do not call to mind having seen 
more than 14 old bucks alone together. ‘The solitaires are, as a rule, old bucks, though 
you do not often see one quite alone at any distance from a herd. I have seen Speke’s 
Gazelle on the Toyoo Plain feeding in the same herd as the Aoul, and the latter are 
frequently in the company of the Hartebeest. The ‘ Aoul’ is, in my opinion, identical 
with the Ariel, which is common in Abyssinia and the neighbourhood of Suakin, but 
it appears to diminish in size somewhat to the north.” 
Of the typical form of this Antelope the British Museum possesses an adult 
male specimen (mounted, but not exhibited), obtained by Esler in the Bogos 
country, and purchased in 1873, also a female from Sennaar received from the 
Stockholm Museum, in exchange, in 1846—probably one of those collected 
by Hedenborg. It has likewise a young male from Abyssinia procured by 
Riippell, the original discoverer of the species, and received in exchange 
from the Frankfort Museum; a skull of a male obtained by Mr. W. Jesse
