The top and sides of the head are dull pea green. The 

 back, sides, and hind limbs are pale straw color, heavily 

 washed with pale olive, and spotted and reticulated with 

 seal brown and black. There are five black blotches on the 

 vertebral line, separated by areas paler than the general 

 tint. The first of these black markings is very small 5 the 

 second is broader than longj the third and fourth are very 

 large and faintly continuous with the blackish brown of the 

 ventral surfaces; the fifth is almost confined to the enlarged 

 medial scales. There are two longitudinal black blotches 

 on the side of the neck, and two corresponding lines on the 

 temple. The chin, gular region, chest, and f orelimbs, are 

 blackish brown. The tail has a ground color of straw yellow 

 clouded with olive, but is dull pea green on the spines, and 

 barred with seal brown terminally. 



The youngest individuals (58 to 76 mm. from snout to 

 vent) are bright terre-verte green above, except on the tail, 

 which has broad rings of dark olive separated by narrow 

 ones of broccoli brown. There are very faint indications 

 of dark vertebral bars. The lower parts are yellowish white, 

 tinged with green. As the animals increase in size, the green 

 gradually disappears and the dark markings increase in size 

 and number until the adult coloration is assumed. The 

 number of femoral pores ranges from four to eight. The 

 dorsal crest seems to be higher in the males than in the 

 females, but is never continued on the posterior part of the 

 back. 



A living specimen was colored as follows: The back and 

 sides are grayish, mottled with black. Three transverse 

 black bands cross the shoulders. The upper surfaces of the 

 fore limbs are black, spotted with gray; of the hind limbs, 

 gray mottled with black. The gular region is black, bordered
