GAZELLES \ 3 



HAY'S GAZELLE 



(Gazella hayt) 

 Native name, Rhazalrim 



This species was named by myself in 1911 (Proc. ZooL Soc., 

 p. 961) on the evidence of a mounted specimen in the British 

 Museum, killed by Mr. M. V. Hay in Algeria, between Constantine 

 and Biskra. Of the size of the dorcas, it is distinguished from 

 that species by the absence of a distinct lyrate curvature to the 

 horns, which carry only about twelve rings in place of twenty-four or 

 twenty-five. The face-markings approximate to those of the edmi, 

 the middle stripe being darker than in the dorcas, with a distinct 

 nose-spot ; the eye-stripes are less conspicuous, and the forehead is not 

 chestnut. There is no faint light stripe above the flank-band ; the 

 knee-tufts are larger and blacker than in the dorcas ; and the tail is 

 brown, in place of black, with a smaller amount of fawn at the root. 

 Apparently the ears are longer than in the dorcas. 



THE RED-FRONTED GAZELLE 



(Page 258) 



The range of the Mongalla (not Mongola) race extends from 

 Gondokoro, in Uganda, northwards to Ber, in the Mongalla district 

 of the Sudan on the Abyssinian side of the Bahr-el-Gebel. The skull 

 of the Libyan race of G. rufifrons differs from that of tilonura by the 

 greater length of the portion in front of the teeth. In rufifrons the 

 length of the tooth-row is 2 T 7 ^ in., and that of the part in front 2^ ; 

 in tilonura these measurements are 2^ and i^. In the much smaller 

 isabella they are 2^ and i-j^-. Skulls and horns of the three species 

 are figured on page 27. 



THOMSON'S GAZELLE 

 (Page 259) 



As mentioned in the " Addenda " issued with the original volume, 

 Dr. E. Lonnberg (" Sjostedt's Kilimandjaro-Meru Expedition," Upsala, 

 1908, p. 46) gave the name of Gazella thomsoni nasalis to the Kili- 

 manjaro race of this species on account of the absence of a black 

 nose-spot. 



Ignoring this, Mr. T. Knottnerus-Meyer, who refers the species to
