Habit lacertiform ; the distance between the end of the snout 

 and the fore limb is contained once and one fourth to once and two 

 thirds in the distance between axilla and groin. Snout short, ob- 

 tuse. Lower eyelid scaly. Nostril pierced in the middle of a small 

 nasal ; a supranasal ; frontonasal broader than long, in contact 

 with the rostral and with the frontal ; latter a little longer than 

 the frontoparietals and parietals together, in contact with the first 

 and second supraoculars ; five supraoculars, fifth very small, second 

 largest ; eight or nine supraciliaries, first largest ; frontoparietals 

 distinct, larger than the interparietal, which entirely separates the 

 parietals ; nuchals often not distinctly diff'erentiated ; four labials 

 anterior to the subocular. Ear-opening small, elliptical, oblique. 

 30 scales round the middle of the body, subequal, dorsals and 

 laterals with three or five strong keels. Praeanals not enlarged. 

 The hind limb reaches the wrist or the elbow. Digits moderately 

 elongate, with strong claws, the basal phalanges somewhat flattened, 

 the distal strongly compressed ; subdigital lamellje smooth, 17 to 20 

 under the fourth toe. Tail a little longer than head and body. 

 Head, neck, and anterior part of the back black ; a pale yellowish 

 or greenish band from the rostral to the occiput ; two others on 

 each side, the upper beginning on the supraciliary border, the lower 

 below the eye ; scattered pale dots between the light bands ; the 

 rest of the body and the limbs olive, with small black and pale 

 spots ; lower surfaces greenish white.
