in contact; about twenty enlarged supraocular scales, the larger

supraorbitals by a series of small scales; occipital larger than the 
ear-opening, separated from the supraorbitals by three or four series 
of scales; six or seven loreal rows in the middle; eight upper 
labials. A distinct nuchal fold. Dorsal scales distinctly keeled, 
hardly half as large as the ventrals, which are also keeled, and 
passing gradually into the small granular scales of the sides. 
Limbs slender; digital expansions well developed. Tail with a 
vertebral series of enlarged scales. Upper surfaces with metallic 
gloss ; a brown cross band between the eyes; loreal region black ;

Head about once and two thirds as long as broad, much longer 
than the tibia; forehead concave, no frontal ridges; upper head- 
scales smooth, or more or less distinctly tricarinate; scales of the 
supraorbital semicircles large, in contact medially; supraocular 
scales very variable in shape and in size, smooth or feebly keeled, 
arranged in two longitudinal series, those of the inner series 
the largest and sometimes much dilated transversely; occipital 
much larger than the ear-opening, separated from the supraorbitals 
by one or two series of scales; canthus rostralis angular, canthal 
scales three or four; loreal rows three or four; six or seven labials 
to below the centre of the eye; ear-opening rather small, suboval. 
Gular appendage moderately large, absent in the female; gular 
scales obtusely keeled. Body not compressed, no dorso-nuchal 
fold. Dorsal scales small, rhomboidal, imbricate, keeled, passing 
gradually into the laterals, which are smaller and granular; ven- 
trals larger than dorsals, rhomboidal, imbricate, sharply keeled. 
The adpressed hind limb reaches the neck or the ear-opening ; 
digital expansions moderate ; fifteen or sixteen lamelle under pha- 
langes 11. and 111. of the fourth toe ; some enlarged granules on the 
hinder side of the thighs. Tail cylindrical, not twice as long as 
head and body, covered with equal, strongly keeled scales. Male 
with enlarged postanal scales. Yellowish or reddish brown above, 
with more or less distinct darker spots or markings ; frequently a
