■ Body moderately elongate, not depressed ; head broadly cordate in adults, less so in 
the adolescent, longer in some than in others ; canthus rostralis not denned anterior 
to the nasal shield, which is circular, non-tubular, with the nostril directed backwards, 
outwards, and upwards in the hinder part of the shield internal to or on the canthus 
rostralis ; ear considerably smaller than the eye-opening, with a fringe of from 2 to 4 
pointed scales along its upper border. Limbs well developed, covered with regular, 
keeled, imbricate scales of moderate size. The wrist reaches to the anterior border 
of the eye or to the nostril, and the tip of the fourth toe to the ear or nearly so. 
Third finger slightly shorter than the fourth, the fifth does not extend so far forwards 
as the second ; the fourth toe considerably longer than the third, the fifth does not 
extend so far as the first. Tibia shorter than the skull, occasionally nearly equal 
to it. Tail longer or as long as the body and head, rounded, non-verticillate, rather 
thick at the base, especially in adult males, covered with regular keeled scales. Upper 
surface of the head covered with more or less convex scales, largest on the mesial line ; 
a number of large, more or less obtusely keeled scales behind the eye, with some 
generally strongly keeled spiny scales on the temporal region. Body covered above 
with moderately sized, unequal, rarely nearly equal, imbricate, more or less acuminate 
or feebly mucronate keeled scales, those on the sides about half the size of the dorsal 
scales and more or less obtusely keeled; 77 to 95 round the middle of the body. 
Ventral scales keeled. 
A well-developed gular pouch in both sexes, largest in the males. No praeanal pores 
are present, but rarely some males show very faint indications of the tendency to 
form feebly callose scales. 
In adult Arabian specimens, in alcohol, the head is pale yellowish tinged with blue 
on the snout and on the occiput and temporal region, and with olive-brown in some ; 
body olive or greyish brown, the sides of the neck, the shoulder, and upper part of 
the fore, limb and sides of the body, and sometimes the mesial line of the back,
