the lacrymal glands. Backs of ears pale fawn-colour; area round their bases 
but little lighter than rest of head. Fawn-colour of throat projecting down 
on to chest, as in Ammodorcas clarkei. Outer sides of limbs pale fawn 
throughout. Tail about 10 inches in length, rufous-fawn like the body basally 
above, whitish below, the tip tufted with black; on each side of its base 
the white of the hams, which is very narrow, runs up as a pointed projection 
into the dark body-colour. 
The skull of an old male measures 8°75 inches in basal length, the greatest 
breadth being 3:8, and the muzzle to orbit 4°7. 
The horns of good specimens attain 15 or 16 inches in length round the 
curves, but southern specimens, those from East Africa, have not, as a rule, 
such fine horns as those from Somaliland. 
Female. Similar to the male, but without horns. 
fab. Somaliland, and thence southwards to the Tana Valley, and the 
Kilimanjaro district of British East Africa. 
This Antelope was first made known to science by the late Sir Victor 
Brooke in 1878 in the last of the many excellent articles which he published 
in the Zoological Society’s ‘ Proceedings.’ His description was based on two 
skulls with horns attached to them which were lent to him for examination 
by Mr. Gerald Waller, F.Z.S., at whose request they were named by Brooke 
after Mr. Waller’s brother, “‘ who lost his life in Africa.” 
Although it is not so stated by Brooke (who was presumably ignorant of 
the fact), Mr. Waller’s specimens of this Antelope are now known to have 
been given to him by Sir John Kirk, at that time H.B.M. Consul at Zanzibar. 
In reply to enquiries Sir John kindly informs us that these skulls were 
procured by hunters in his employment on the coast near the River Juba in 
Southern Somaliland. Sir John subsequently shot specimens of it himself 
in the same district (where at that period it was very common), and also 
brought living examples of it away to Zanzibar. 
In his description Brooke pointed out that, as is well shown in the 
acwompanying figure (p. 231), which has been copied from the plate that 
illustrates his paper, the skull of this Gazelle, besides its general depression, 
stands widely apart from those of all other species of the group in the enormous 
backward prolongation of the occiput—* an extension gained principally by 
the great size of the occipital bone and the prominence of the occipital crest ”
