16 <J and 20 ?. Maryut District. 
Snout obtusely or acutely pointed ; two entire supraoculars separated from the super- 
ciliaries by two lines of granules : the first supraocular broken up generally into two or 
three pieces or wholly into granules, rarely entire, and the fourth reduced to granules, 
but with one or two small pieces remaining. Subocular generally between the fourth 
and fifth upper labials, rarely between the third and fourth, or the fifth and sixth, 
not unfrequently entering the labial margin. Front margin of the ear generally 
denticulated, but the denticles are, in some, reduced to granules. Temporals variable, 
usually convex, elongate, rounded, or polygonal, smooth or keeled. Dorsal scales 
granular, convex, smooth, but occasionally flattened and becoming rhomboidal and 
imbricate posteriorly, and more or less keeled and increasing in size towards the 
hinder part of the body, but always smaller than the caudal scales. Fifty-six to 
eighty-five scales round the middle of the body. Ten to fourteen ventral plates, 
generally twelve, broader than long, and arranged longitudinally and transversely. An 
enlarged prceanal plate, with two or three smaller plates anterior to it and also at its 
sides. Limbs moderately long, variable in length, and rather stout ; hind limb 
generally reaches in advance of the shoulder, in some examples more so, but in others 
it only touches the axilla. Digital denticulations feebly developed on the fingers, 
moderately strong on the toes, longest on the fourth ; claws short, moderately curved. 
Tail about once and a half as long as the body and head, or longer ; scales on its 
upper surface large, generally strongly keeled, those on the under surface smooth or 
obtusely keeled. Fifteen to twenty-four femoral pores. 
Lineated, in the young state, with six white and seven black bands on the middle of 
the body. The bands or lines are lost with advancing age and the dorsal surface is 
covered with a broad network of black bands, here and there marked with white spots 
in longitudinal arrangement, as they are the remains of the white bands. 
General colour, in the adult, olive-green, fawn, or even almost orange-red. Very 
variable in the degree to which the markings are developed. Underparts generally 
white, but in some the throat and ventral surface are finely speckled with dusky. 
The largest Egyptian male has the following measurements: — Snout to vent 68 
millim., tail 99 millim. ; but the species attains to a considerably larger size in 
Algeria and Somaliland.
