48 THE REPTILES OF EGYPT. 
cycloid, imbricate, and strongly keeled, the keels being arranged in continuous ridges. 
On the under surface of the head the scales are finely granular, but on the rest of the 
under surface of the body they are imbricate and strongly keeled in lines ; those of the 
middle of the belly are about one half the size of the scales of the back. About 50 
rows of scales round the middle of the body. No prseanal pores. 
General colour of the upper surface pale yellowish, speckled with fine dark brown 
dots and some obscure white spots. A well-marked dark brown band runs from the 
nostril to the eye, and is continued above the ear to the shoulder. Upper surface of 
tail in its first third coloured like the back, but beyond this with broadish brown 
transverse bars, about 16 in number in a perfect tail. Upper surface of limbs 
concolorous with the back ; under surface nearly white. 
Snout to vent 35 millim. ; tail 49. Total length 84 millim. 
Among loose sand and pebbles, under stones, around the Pyramids of Gizeh. 
This species was first discovered in Tripoli by Drs. Rohlfs and Stecker on their 
journey to the oasis of Kufra. Since then it has been found in four localities in 
Tunisia. 
It was unknown in Egypt until I found it in the locality already indicated. It 
would be interesting to know what its distribution is in Egypt, and whether it occurs 
on the right as well as on the left bank of the Nile like the next species.

1. Desert of Philse. 
Head elongately oval, rather flat above ; snout exceeding the distance between the 
posterior border of the eye and the ear ; diameter of the eye about two-thirds the 
length of the snout ; ear very small, less than one-third the diameter of the eye, 
situated slightly below the level of the angle of the mouth ; nostril defined by the 
rostral anteriorly, below by the first labial, and above and posteriorly by two scale-like 
nasals ; rostral traversed by a longitudinal groove ; 7 to 9 upper and 6'lower labials ; 
mental as broad as the rostral, with a pair of shields behind it, in contact with one 
another, and with a smaller shield behind each of them. Limbs moderately long, the 
fore limb reaching before the eye or to halfway between the eye and the snout, and the
