 Bed Sea.

 and darker coat, and smoky brown pygal and flank bands. 



Size medium, shoulder -height 24 or 25 inches. Horns 

 rather short and thick, nearly parallel, with a slight backward 

 curve, and a forward inclination at the tips ; general colour 

 dark smoky fawn, darker than in any of the allied species ; 

 median face-stripe dark rufous fawn, with a black nose-spot ; 

 ears medium, brownish fawn on backs ; flank- and pygal 

 bands dark smoky brown ; limbs more rufous than body. 

 Basal length of skull about 6 j inches, maximum breadth 3, 

 length from muzzle to orbit 3| inches. Good horns measure 

 from 8J to 10J inches in length, with a basal girth of from 

 4 to 4J, and a tip-to-tip interval of from 4 to 4J inches. 



The range is restricted to western Arabia. 



The species has been divided into three local races, 

 distinguished as follows : 



A. Flank-band present. 



a. General colour dark smoky fawn G. a. erlangeri. 



b. General colour pale sandy fawn like that of 



dorcas G. a. rueppelli. 



B. Flank-band wanting G. a. arabica. 



Whether these characters are constant, the specimens in 

 the Museum are insufficient to determine.
