2 J 1 and 4 ? . Marsa Matru. 
Casque moderate, raised posteriorly, anteriorly convex ; a small occipital dermal lobe 
on each side continued to the apex of the casque ; supraorbital ridge prolonged on 
to the casque, but becoming indistinct as it ascends ; the distance between the angle 
of the mouth to the apex of the casque about equals the length of the labial border ; 
the distance from the base of the casque anteriorly to its summit almost equals the 
distance between the tip of the snout to the middle of the eye. Limbs well developed ; 
no tarsal spur in the male. Tail shorter than, or as long as, the body and head. 
Sides of the head and casque with small and large polygonal tubercles, more or less 
conical or flat, largest on the free borders of the occipital lobes. Body with minute 
granules, somewhat varying in size, largest along the throat-folds. A feeble dorsal 
ridge of enlarged, somewhat pointed, conical tubercles, with a line of enlarged body- 
granules on each side of it. A gular ridge of large, conical, backwardly pointed 
tubercles, becoming gradually reduced in size posteriorly. 
Colour usually green, with two interrupted white bands from opposite the middle of 
the occipital lobe, along the sides, to the base of the tail, and another from the axilla 
to the groin margined with darker green. The intervals between these lateral markings 
are leaden black in some, with still blacker spots. Occasionally there are about 26 
reddish-brown cross-bands between the nape of the neck and the end of the tail. The 
mesial ventral line of scales white. In some specimens the colour is greyish brown, 
with similar markings as in the green phase. 
The majority of specimens from Ain Musa were green, but some of them showed no 
traces of that colour in life, being wholly greyish brown. At Marsa Matru, where the 
species is common, this colour also occurs, and I have figured it in contrast to the green 
or more prevalent colour. This brown colour has been noticed by other observers.
