Head rather elongate ; snout obtuse. Two superposed post- 

 nasals ; frontal narrowed posteriorly, more or less distinctly grooved 

 anteriorly : two large supraoculars, with a few small sliields in 

 front and behind, and a scries of granules externally ; interparietal 

 narrow, much longer than broad ; occipital small ; a small shield is 

 occasionally present between the two latter ; a band-like shield 

 borders the parietal, and another, curved one, the ear supero- 

 anteriorly ; temporal scales granular, smooth or obtusely keeled ; 

 no auricular denticulation ; subocular bordering the lip, between 

 the fifth and sixth or sixth and seventh upper labials. Gular 

 scales small, smooth : the three anterior pairs of chin-shields in 

 contact; collar slightly curved, with toothed edge, formed of 9 

 to 11 large plates. Dorsal scales small, granular or rhomboidal, 

 juxtaposed, smooth on the nape, more or less distinctly keeled 

 and increasing slightly in size on the back; 55 to 65 scales across 

 the middle of the body (counting from the ventials). Ventral 

 plates in G or 8 straight longitudinal and 27 to 30 transverse series 

 (from the collar-fold to the prasanal region) : the shields of the 

 two median series narrower ; the outermost series, if present, com- 

 posed of still smaller shields ; a group of smaller irregular shields 

 on the pectoral region. Prieanal region covered with small irre- 

 gular shields, or with a large transverse postero-median shield. 

 The hind limb reaches the collar or between the latter and the ear ; 

 a series of very large, and one of smaller, subtibial plates. 5 to 

 12 femoral pores on each side. Tail more than twice as long as 

 head and body ; upper caudal scales strongly keeled, basal sub- 

 caudals smooth. Yellowish or pale brown above, with longitudinal 

 blackish streaks or series of spots on the back ; the vertebral streak 

 is the most constant ; a brown band on each side of the body, usually 

 bearing a series of large blue ocelli ; sides of head and body fre- 

 quently with vertical black bars ; upper surface of limbs with dark 

 network ; lower surfaces white.
