Snout obtuse, projecting very slightly, if at all, beyond the labial margin ; eye 
moderately developed ; ear-opening more or less triangular, moderately large, and 
placed some distance behind the commissure of the mouth. Nostril small, over the 
suture between the rostral and first labial ; supranasals in contact behind the rostral, 
their length about one half of their breadth ; nasal small, crescentic, with a postnasal 
behind it in contact with the supranasal, first loreal, and first and second labial, rarely 
with the second only; frontonasal broader than long, in contact with supranasals, first 
loreal, first supraorbital and frontal ; frontal nearly as broad as long ; generally 8 upper 
labials, rarely 7 or 9, the fifth usually under the eye, the last the smallest. Sides of 
body rounded; 24-40 scales round the body (usually 26-32 in Egypt), smooth or 
feebly striated. Limbs short, but well developed ; digits 5 — 5. The length of the fore 
limb is less, sometimes considerably so, than the distance between the axilla and the 
eye ; the hind limb is generally shorter than the interspace between the axilla and the 
tip of the snout. Tail variable, generally longer than the head and body. 
Coloration variable, but generally the upper surface is brown or olive-brown, 
occasionally greyish, marked by narrow transverse black bands about the breadth of a 
scale, and not unfrequently broken up into closely opposed spots, each with a longi- 
tudinally narrow white spot or shaft. In others the black and white spots of the back 
may entirely disappear, or if present be small and feebly developed, and in such cases 
there is generally a light-coloured stripe down each side of the lizard, thus denning a 
brown dorsal band. In some, the spots are absent on the body but present on the 
sacral region, on the tail, and on the hind limbs. 
The largest specimen in my collection from Egypt measures as follows : — Snout to 
vent 122 millim., tail 84 millim.
