Colour. — The upper parts of the head, the back, and the upper parts of the 
sides rusty oil-green, shaded with reddish brown, and variegated with small 
spots and short longitudinal stripes of wine-yellow. Sides of head and outer 
and hinder surfaces of extremities light sap-green, the lower portion of the 
sides, the inner surface of the extremities, the toes, and all the under parts 
wine-yellow, shaded with brownish orange ; and the under surface of the 
head blotched with irregular spots and stripes of a clove-brown colour. Eyes 
deep chestnut-brown, highly variegated with yellowish white dots having a 
strong metallic lustre. In young specimens the variegations in respect of 
colour are more defined, and consist of vertical bars on the upper lip and 
lower parts of the sides, of longitudinal waved stripes on the back and upper- 
parts of the sides, and of transverse bars on the outer surface ol the 
extremities. 
Form, &c. — Figure robust. Head depressed, posteriorly very broad, 
anteriorly narrow and rounded ; its upper surface is rather concave, having a 
broad longitudinal depression extending from the hindhead nearly to the 
nose. The nostrils are situated at the upper and anterior part of the head, 
each about midway between the edge of the upper lip and the anterior canthus 
of the eye, are small, ovate, and with their opening directed outwards and 
backwards. Eyes moderately large, the upper eyelid broad and granular 
externally, except at its ciliary margin. Mouth large, and its angles about 
the same distance behind the eyes that the eyes are behind the nostrils.
