Forest Garden Lizard

C. emma has the following morphology. Physical Structure: There are 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. The dorsal crest is well developed on the neck and on the anterior part of the trunk, gradually disappearing behind. There is a transverse fold in front of each shoulder, and the gular sac is but little developed. The tail is laterally compressed. There are about 51 series of scales round the middle of the trunk. Color pattern: The dorsum is brownish olive, with brown bands across the back, which are lighter in the middle and interrupted by a white band running along each side of the back. The eyelids have short, radiating brown streaks. There is a brown band from behind the eye to above the tympanum. The fold before the shoulder is black, with an irregular white margin. The legs and tail have indistinct dark crossbands. The maximum total length (including tail) is 40 cm (16 in). The usual total length is 28 cm (11 in), and the usual snout-to-vent length (SVL) a 7.5 cm (3.0 in).

C. emma is found in Bangladesh (Satchari National Park, Bandarban Hill District), Cambodia, China (Guangdong, Yunnan), India (Assam), Laos, Malaysia (Peninsular), Myanmar, Thailand (including Phuket) & Vietnam (including Pulo Condore Islands) and Possibly in Bhutan. "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. Mr. Blyth mentions it amongst a collection made by Captain Bedmore at Schwe Gyen on the Sitang River in Pegu".
