A large indi^ddual of this species was obtained at Klong 

 Menao. 



Total length 89G mm., snout to vent 231. In an example of 

 about half the size found on Koh Kut tiie colouration was much more 

 brilliant than in the okler one. General colour above, brownish green, 

 darkest on the head ; body with 3 broad diagonal bars of paler blue- 

 green edged with brown ; tail pale isabelline with brown bands ; hind 

 legs above greenish brown. Underside of body, tail and forelimbs white, 

 with a bright blue tinge in places ; chest, patches on sides', under sur- 

 face of legs, bright emerald-green ; upper labial scales'rose-pink washed 

 with green, lower labials and sub-labial row of scales rose-pink, the 

 latter edged with black ; throat reddish yellow. Iris brown with an 

 inner golden ring round the pupil. 



This species, which is known from Siam, differs mainly from 

 P. cochincJmiensis of Oochin-China, in the possession of a lesser 

 number of lateral or molar teeth, and in the presence of eleven large 

 sub-iabial scales instead of only six or seven. 



The individual referred to above from Koh Kut, was kept alive 

 for some time. It was a ver}' sluggish creature, sitting about on the 

 ground or in a tree, quite motionless, for most of the daj^ It never 

 attempted to bite when handled. It was fed upon fish, meat, worms 

 and insects. It was never seen to take food of its own accord, but on 

 scratching its jaws would open its mouth and then take whatever was 

 given it. Its power of changing colour was very slight, and varied 

 only from light to dark. When running fast over ground, its action 

 was bipedal, the fore limbs being folded back along the flanks. A 

 young specimen of this lizard has been recently taken at Muak Lek,
