Snout obtuse or, at any rate, less acute than in A. scutellatus. 

 Three .supraoculars, the anterior frequently divided into two or 

 three; subociilar usually not reaching the lip ; temporal scales not 

 keeled ; front edge of ear more or less distinctly denticulated. 

 Dorsal scales very small, subgranular or rhoraboidal, smooth or 

 more or less distinctly keeled. Ventral plates broader than long, 

 sometimes very slightly, in 12 or 14 regular longitudinal series ; 

 the transverse series usually slightly angular. Usually a median 

 series of transversely enlarged pra^anals, posterior largest. The 

 hind limb usually reaches the axil or the shoulder, seldom a 

 little beyond the latter. Digital denticulations feebly or moderately 

 developed, constantly much shorter than the diameter of the corre- 

 sponding part of the toe, slightly more developed on the outer than 

 on the inner side. Upper caudal scales keeled ; basal subcaudals 

 smooth or feebly keeled. Young longitudinally streaked, as in 

 A. vulr/aris. Coloration of the adult very variable, usually with 

 longitudinal blackish and yellowish spots, the latter sometimes con- 

 fluent into longitudinal bands ; the desert specimens pale, greyish 

 or reddish.

A. pardalis is a transitional form between A. scutellatus and A. 

 vulgaris. It is represented by two ill-defined varieties, which have 

 been named by Lataste var. bedriagce, the larger, stouter form, 

 approaching A. vulgaris in structure as well as coloration, of which 

 dimensions are given above ; and var. deserti ( = S. maailata. Gray, 

 Z. deserti, Gthr.), the smaller form from the Sahara, which often 

 closely approaches A. scutellatus.
