The shape of the head and the general proportions are much as in 



the typical form, but the hind limb is often a little shorter, reaching 



the collar, the ear, or between these two points in males, the axil, the 



shoulder, the collar, or a little beyond, in females ; tail U to 2 times 



length of head and body. 



Dorsal scales rhombic, fiat, juxtaposed or subimbricate, and strongly 



keeled, the upper laterals often only a little smaller and also keeled ; 



60 to 59 -scales across the middle of the body. Ventral plates in 

 12 or 14 longitudinal series ; 28 to 38 transverse series. 20 to 26

The type specimen is represented as with distant blackish dots and 

 a broad light lateral band from the ear to the thigh, bordered by a 

 blackish streak beneath, and broken up here and there on the body by 

 dark vertical lines. The specimen from Wadi Haifa mentioned above 

 has the white lateral band continuous and edged above by a series 

 of ocellar spots. Other specimens from the same locality are greyish, 

 speckled, vermiculated or reticulated with blackish. Among specimens 

 from Tripoli and Tunisia, some are speckled above and ocellated on 

 the sides (males), or uniform grey with a whitish dark-edged lateral 

 band and a blackish streak along each side of the tail (females) or
