10. ACAXTHODACTYLrS. 61 



Four supraoculars ; subocular not reaching the lip ; temporal scales 

 keeled ; front edge of the ear usually rather feebly, but distinctly, 

 denticulated. Dorsal scales strongly keeled, very much larger on 

 the hinder part of the back than between the shoulders and on the 

 flanks, rhomboidal, strongly imbricate ; 10 to IG large keeled 

 scales on a transverse line between the hind limbs. Ventral plates 

 usually broader than long, narrower than in A. boskianus, in straight 

 longitudinal and slightly angular transverse series ; 12 or 14 

 plates across the middle of the body. Usually a median series 

 of broad pra^anals, posterior largest. The hind limb reaches the ear 

 or the eye. Digital denticulations strong, usually as long as the 

 diameter of the corresponding part of the toe, much more developed 

 on the outer than on the inner edge of the fourth toe. Upper caudal 

 scales strongly keeled : basal subcaudals smooth or obtusely keeled. 

 Coloration as in A. bosJcianus.
