Anterior teeth small, sharply pointed, those behind them rather large and conical. 
Snout depressed at its extremity ; canthus rostralis well denned. Nostril small, round, 
situated nearly midway between the end of the snout and the eye, but nearer to the 
latter than to the former. Tail much compressed, with a well-defined dorsal ridge. 
Digits moderately long. Scales on the upper surface of the head of moderate size, 
smallest on the temporal region and subequal on the supraocular region. Scales 
on the body and limbs small, oval, or pear-shaped ; caudal scales keeled ; ventrals 
smooth, 75 to 100 between the gular and unguinal folds. 
In the young and even in the half-grown the body is blackish above. The upper 
surface of the head with fine wavy transverse yellowish lines, and the sides, from the 
snout to the ear, marked by vertical black spots or bars broken up with yellowish. A 
pale yellow band from the eye to the ear, with a black band above it directed back-

and a number of similar bands behind it with intervening pale yellow lines forming 
V-shaped markings. Eight narrow, yellow, transverse bands across the back, always
