MAMMALIA. 261 



the genus as G. dama and G. euchore, distinguished 

 from G. dorcas and its allies, the true gazelles, by their 

 less symmetrical form and longer legs, and by their habit 

 of keepiag in herds of considerable size. Their pace is 

 rapid, usually a long trot : I never saw them bound like 

 the Springbok or like Antilope hezoartica of India. 



On one or two occasions I saw tracks of Gazella 

 Scerhmerringii near water, and Captain Mockler shot 

 one while drinking. The hour of drinking appears to 

 be usually a little before midday. In this it difiFers 

 from Gazella dorcas and its near ally G. Bennetti of 

 India, which never drink.

The true Gazelle of the Abyssinian coast-land appears 

 to differ in no essential character from that of Northern 

 Africa. A distinguishable race inhabits the opposite 

 shore of the Eed Sea {G. arabica, H. and E.), and a 

 third form, G. Spehei, Blyth, occurs on the African coast 

 further south in the Somali country. Figures of the horns 

 of all these races are appended (Plate I), as well as of 

 two other Asiatic Gazelles, G. subgutturosa of Persia and 

 Beloochistan, and G. Bennetti of India. The figures 

 of G. dorcas are from specimens shot by myself near 

 ZuUa ; that of G. arabica from a head for which I 

 am indebted to Captain Heysham of the Co mmi ssariat, 

 who obtained it at IMocha. The figured heads, male 

 and female, of G. Spekei, are the specimens described 

 by Mr. Blyth in the Journal of the Asiatic Society
