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

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

 4 to 4^, and a tip-to-tip interval of from 4 to 4| 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.
