Appearance
From C. A. L. Gunther The Reptiles of British India.Three small groups of spines, completely separate from each other, on each side of the head—one behind the superciliary margin and two above each tympanum. Dorsal crest well developed on the neck and on the anterior part of the trunk, gradually disappearing behind. A transverse fold in front of each shoulder; gular sac but little developed. Tail compressed. About fifty-one series of scales round the middle of the trunk. Brownish olive, with brown bands across the back, which arc lighter in the middle and interrupted by a white band running along each side of the back; eyelids with short, radiating brown streaks; a brown band from behind the eye to above the tympanum; fold before the shoulder black, with an irregular white margin; legs and tail with indistinct dark cross bands.
An inhabitant of Mergui, whence we have received it from Professor Oldham, ranging northwards perhaps to the Khasya Hills; extremely doubtful as an inhabitant of Afghanistan. It attains to a length of 11 inches, the tail measuring 8 inches. Mr. Blyth mentions it amongst a collection made by Captain Bedmore at Schwe Gyen on the Sitang River in Pegu.
