and a long upper lip, just like those of G. wallert or a Giraffe. The horns are of the shape 
of a sickle, and less than 12 inches in length, the longest, out of the eleven males killed, 
measuring 1] inches. The tail, from what I remember, is about 12 or 13 inches in 
length, very thin, and thinly covered with black hair about 1 inch long. 
“The colour of the body in this Antelope is like that of the neck, of a kind of 
pink-fawn, but the belly is whitish and the tail black. The face resembles that of 
G. walleri, only G. walleri has no white in front of the eye. 
“When running, or rather jumping, these Gazelles look very peculiar; their long 
neck and head being thrown back and the tail thrown forward, so that there appears 
to be only a foot between head and tail. The country they are mostly found in is of 
low thorn-bush and sandy ; they do not seem to like the big bushes, though at times 
they are found there. In this respect they differ from G. wulleri, this’ species liking 
* many bushes to go and rest in. 
“The new Gazelle is to be found one day’s journey from Buroa Wells, at an 
elevation of 3100 feet, to the Marehan country (800 feet) (general course about S. by 
E.), and is there more numerous than any other kind of game, excepting G. soemmerring/; 
but the latter is found only in the open country. 
“Several times I observed the new Gazelle and G. walleri feeding together, but 
I never saw more than eight in a bunch, and on that occasion there was a male 
G. soemmerringi with them.” 
Mr. Clarke’s skulls of this Antelope, which were at the time without 
head-skins, having been submitted to Thomas for examination by Messrs. 
Rowland Ward and Co. (to whom Mr. Clarke had sent for preservation his 
specimens of Antelopes obtained during this expedition), were, on account 
of the shape of the horns, not unnaturally supposed to belong to a new 
species of Reedbuck, and named “ Cervicapra clarket”—a mistake which 
Thomas corrected in his later paper. Very shortly after Mr. Clarke’s 
specimens had been sent to Europe Capt. Swayne purchased of an Arab in the 
market at Berbera two pairs of horns of this Antelope with the head-skins 
attached, and, seeing that they belonged to a new species, sent them to 
Sclater. Sclater exhibited these specimens at a meeting of the Zoological 
Society on March 17th, 1891, and pointed out their Gazelline affinities, but 
finding that they belonged to the same species as that just named by Thomas 
handed them over to the latter for further examination. 
In his paper upon this subject, which was read at the same meeting of the 
Zoological Society, Thomas took the opportunity of describing the whole 
series of Mr. Clarke’s Antelopes, which were eight in number. For Clarke’s 
Gazelle, of which, with the aid of the head-skins and the cleaned skulls, he 
had no difficulty in recognizing the true affinities, he established the new
