' distance from the end of the snout, twice as long as broad, narrow 

 behind, separated from the supraoculars by a series of small scales ; 

 parietals as long as broad or a little broader than long, not longer 

 than the frontoparietals ; interparietal small,* usually separated from 

 the vei-y small occipital by another small shield. Three supraoculars, 

 in contact with each other, first nearly as long as second, sometimes 

 partly broken up into small scales ; 7 superciliaries, first longest, 

 separated from the second and third supraoculars by a series of small 

 scales. Four nasals, two upper and two lower ; anterior loreal a little 

 longer than deep, much shorter than the second ; 6, rarely 5, upper 

 labials anterior to the centre of the eye, the two first in contact with 

 the lower nasals; subocular keeled below the eye, not reaching the 

 mouth, its lower border wedged in between the sixth and seventh (or 

 fifth and sixth) upper Libials. A long and narrow upper temporal, 

 followed by smaller shields ; temporal scales granular, keeled. Lower 

 eyelid opaque, with small scales. 



6 pairs of chin-shields, the 2 or 3 anterior in contact in the middle ; 

 30 or 31 gular scales in a straight line between the symphysis of the 

 chin-shields and the median collar-plate : no gular fold. Collar 

 curved, free, with 7 to 9 shields. 



Scales rhombic, juxtaposed or subimbricate, keeled, some even tri- 

 carinate, 53 to 68 across the middle of the body. Ventral plates in 6 

 or 8 straight longitudinal and 25 to 27 transverse series, much broader 

 than long ; if in 8 series, the outer plates very small. A more or less 

 enlarged median preanal plate. 



Scales on the limbs strongly pluricariuate ; lower surface of tibia 

 with one row of very large and one row of small plates. 20 to 24 

 femoral pores on each side. 21 to 24 unicarinate lamellae under the 

 fourth toe. 



Touug with six reddish white streaks along the body, separated by 

 broader black streaks, along each of which runs a series of small 

 round whitish spots ; head reddish brown above ; limbs with a black 

 network enclosing lai-ge rouud reddish white spots ; tail striped with 

 black at the base, uniform coralUne red in its posterior half; lower
