The toes are as long as in the long-toed Varani, and armed with sharp claws of moderate size. The teeth are strong, slightly compressed and curved backwards, not serrated. A series of broad, enlarged shields covers the inner half of the superciliary region. Scales of the neck and back with a very obtuse keel; those of the belly smooth, in 90 transverse series between the gular fold and the loin. Dark brown above, with transverse series of round white spots; snout with three or four white cross bands; a dark-brown streak runs from the eye to the neck; throat and sometimes the belly with irregular dark-brown transverse streaks; tail with white rings. All these markings become more and more obscure with advancing age, and, finally, may disappear entirely.
This species is an inhabitant of the islands of the East Indian Archipelago; the British Museum, however, has received two examples from the continent-one from China, by Mr. J. Lindsay, and the other from Siam, by Sir J. Bowring.

Kelaart (Pro dr. Faun. Ceyl. p. 148) and Blyth (Journ. As. Soc. Beng. xxii. p. 476) state that it also occurs in Ceylon, whence we have never received it.
According to Cantor it is "very numerous in hilly and marshy localities of the Malayan peninsula. It is commonly during the day observed in the branches of trees overhanging rivers, preying upon birds and their eggs and smaller lizards, and when disturbed, it throws itself from a considerable height into the water; it will courageously defend itself with teeth and claws and by strokes of the tail. The lowest castes of Hindoos capture these lizards commonly by digging them out of their burrows on the banks of rivers, for the sake of their flesh, which by these people is greatly relished. Some individuals attain to nearly 7 feet in length."
