10. ACANTHODACTYLUS. 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 16 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 preanals, 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. boskiunus.

Snout obtuse. Four supraoculars; subocular not reaching the 
lip; temporal scales smooth or indistinctly keeled; front edge of 
ear not or but very feebly denticulated. Dorsal scales strongly 
keeled, very small on the nape, gradually increasing in size towards 
the posterior part of the back, where they are very much smaller 
than the caudals, rhomboidal, imbricate; 18 to 22 keeled scales
