in contact with the mental, the 3 first pairs in contact with the anterior chin shields. Temporals relatively 

 large, whereas posterior chin shields are small. Dorsals rhombohedral, keeled, arranged in 25 rows at 1-2 

 head length behind the head, 25 rows at midbody, 1 7 rows at 1 -2 head length before vent, scales of the 

 outer row smooth. Ventrals 189; anal entire. Tail lateraly compressed, mainly at its posterior part; 63 

 subcaudals, the first 62 paired, the 63th single, their outer margin being bent downwards up to the middle 

 of the tail; dorsal part of the tail covered with relatively large, regularly arranged scales on rows of which 

 the number progressively decreases backwards fi^om 9 rows to 7, down to 4 rows at the end of the tail. Tail 

 spine squarish and hard. 



Total length: 447 mm t'*'*!, tail length: 65 mm. 



Body entirely blackish brown marked with minute yellowish green or rusty spots which give a pattern 

 similar to net meshes; along each side, a series of transversal bands made of about 40 yellowish green 

 scales covering in width fi-om 3 to 5 scale rows, evenly separated, confluent or slightly set off one fi^om 

 each other on the vertebral line. Ventrals also marked with minute spots like the back, and with larger 

 subtriangular, yellowish green blotches. Upper surface of head blackish brown, with symmetrical yellowish 

 green markings. Upper surface of the anterior part of the tail marked like the body, whereas the posterior 

 tail part is very pale yellowish green or nearly white. Iris pale yellowish green. Adults have similar colors 

 and patterns t'*^!. 



Variations in paratype: 7 small scales in a row between the supraoculars, 3 postoculars at right, 15 

 infralabials at left, 14 at right, 195 ventrals, 60 paired subcaudals. Total length: 444 mm, tail 

 length; 65 mm.
