CLARKE'S GAZELLE. 131 



given : "The Somali name for these antelopes is ' Debo Tag.' I shot 

 them in the new country I went into, and did not see them in any 

 other part. They have a very thin long tail, and when they run, 

 throw it up and over towards the neck. The neck is very long and 

 thrown back towards the tail, so that the two look as if they would 

 touch each other." 



Shortly after the arrival of Mr. Clarke's specimens, Mr. Sclater 

 received from Mr. Swayne two scalps of this species which he had 

 bought in Berbera, and these scalps Mr. Sclater has most kindly 

 handed over to me for the purposes of the present paper. For- 

 tunately, the muzzle of one of them has been preserved, so that I 

 have been able to make out its strictly Gazelline character, and the 

 description of the colours above given has also been taken from these 

 specimens. 



It is much to be hoped that more specimens of this beautiful 

 Gazelle will soon be obtained, and that we may thereby gain a full 

 knowledge of its range, habits, and natural affinities. 



P.S. (May I4th). Mr. Clarke has favoured me with the following 

 notes on this new Gazelle : 



" I saw this Gazelle for the first time on December I7th, 1890, 

 about three hours from Bairwell, or about one day from Buroa Well, 

 Habergerhagi's country, and afterwards on the road all the way into 

 the Marchan district, 8 N. 47 E. I killed a male, and found one of 

 the horns broken off close to the skull, which had apparently been 

 done a year or so ago. 



" They are very graceful animals, with a long neck and well-propor- 

 tioned head and horns ; the body is rather slender, but considerably 

 larger than in Gazella spekii, about the size of a female G. walleri. 

 The legs are long and slender; the hoofs are not so triangular as 

 those of G. spekii, and small for the size of the animal." 



Mr. Clarke informs me that the female of Ammodorcas is without 

 horns, a character which allies it still more closely with Lithocranius, 

 and removes it from the typical Gazelles. The exact locality at which 

 he obtained the specimens is about a day and a half from the Buroa 

 Wells, Central Somali, about 100 miles south of Berbera.
