 one-third of length.

Head shields — Normal. The supra-oculars overhang 

 and shelter the eye. Two prse-oculars, the 

 upper reaching right into the crown of the 

 head. Generally 3 loreals. Two nasals. The 

 head shields, especially the 8 supra-labials, 

 have black margins. 



Scales — 17, not markedly keeled, except perhaps the 

 middle rows towards the tail. 



Ventrals—196 to 208 ; anal bifid. Sub-caudals, 108—134, 

 double.

 olive green ; with interstitial skin-colouring 

 of yellow and black. Scales with black tips. 

 Ventrals have thin posterior black edges, with 

 a row of black dots on each side of them. 

 This on the double sub-caudals makes a re- 

 ticuled pattern on the tail. Belly greenish or 

 yellowish white. 

 When young is often a delicate green colour, 

 unlike the adult.
