Body moderately elongated, but depressed ; head subcordiform ; nostril on the 
canthus rostralis in the hinder part of the nasal, and directed upwards and backwards ; 
ear round, smaller than the eye-opening, with a feeble fringe of pointed scales along its 
upper border ; the tibia and skull (occiput to snout) are nearly equal, sometimes longer 
and sometimes shorter than one another. Limbs variable ; the wrist may reach to any 
point between the eye and the nostril, and rarely beyond the snout; the tip of the 
fourth toe may reach to any point between the shoulder and the ear, or may extend as 
far forwards as the eye; tail depressed, and broad at the base, tapering gradually to a 
rather fine point and rounded ; not unfrequently much longer than the body and head, 
but much shorter in some than in others. Scales on the upper surface of the head 
smooth or slightly keeled, more or less convex on the frontal region, and generally 
keeled on the temporal area ; a minute spine or two on the post-temporal region in 
the finely-scaled forms, but occasionally absent, most marked in those with a coarse 
lepidosis. Body covered with small, equal, rhomboidal, smooth, indistinctly or distinctly 
keeled scales, somewhat larger than the ventrals, with a few slightly, if at all, larger 
1 Riippell, in Neue Wirbelth. p. 14, seemed doubtful whether his A. Jlavimaculata was distinct from the 
A. ruderata (= A. pallida) of the Descr. de l'Egypte, but they are two very different species.
