p. 165, pi. VII., figs. I and 2. 
Snout almost twice as long as the diameter of the eye opening, 
with projecting canthus rostralis and very concave lores. Nostril 
slightly nearer the eye than the tip of the snout, directed upwards 
and backwards, pierced in an enlarged nasal situated below the 
angle of the canthus rostralis. Rostral small, broader than long, 
roughly hexagonal. Tympanum large, vertically elliptic but slant- 
ing slightly forwards, its vertical diameter equal to that of the eye 
opening. Upper head scales sub-equal, smallest on the supra- 
orbital region, mostly tricarinate, the keels meeting at the posterior 
extremity of each scale. A superciliary ridge with elongate uni- 
carinate scales. Scales much smaller on the temporal region. 
Scales bordering the upper lip, regular, not enlarged. A ridge of 
enlarged scales runs from beneath the eye to above the tympanum. 
Several small folds of skin on the neck bearing groups of small 
conical spines. Gular scales small, flat, sometimes faintly keeled, 
enlarged and hexagonal towards the lower labials. Mental longer 
than broad, slightly larger than the rostral. Scales of the upper 
surfaces strongly keeled, very slightly enlarged towards the verte- 
bral region. A very distinct nuchal crest continuous behind with a 
vertebral series of slightly enlarged scales, or a distinct dorsal crest. 
Scales of limbs larger than body scales. Ventral scales keeled, 
larger than dorsal scales. Fore limb moderate ; hind limb long, the 
toes of the adpressed limb reaching to the eye or the loreal region ; 
the length of the foot equals that of the fore limb. The male with 
fifty to fifty-three praeanal and femoral pores forming an uninter- 
rupted series on each side. Tail depressed at the base, with a 
serrated ridge not distinguishable on the posterior third of its 
length.
