Siamese. " Tooa-yaa.'"' 



For brilliancy and beauty of colour few animals can vie vidth 

 this lizard. Although Cantor was such an admirable observer of 

 natural history, it seems probable that when he wrote of this 

 lizard " leaping from branch to branch," it was conjecture or what 

 he had been told of its habits, and not what he had actually seen ; 

 for, on the authority of Theobald and Davison, we know that it is 

 terrestrial and a burrower, and Mr. Eidley has told me the same 

 and also that it frequents sandy localities, where it makes its 

 burrows. Personally, I have not seen its burrows, but when 

 coming on an individual among a grove of bushes it made oii by 

 running on the ground, instead of climbing into a bush as the 

 arboreal Agamoids do. It is diurnal, and in spite of its rather 

 heavy build can run very quickly (as Cantor also remarked). Some 

 classes of Siamese and Laos eat this lizard, and esteem it a 

 delicacy. 



Localities. Province Wellesley (Cantor), Kalantan and on the 

 Eumpin Eiver in Pahang (Davison) ; and I have seen specimens 

 from three places in Siam — Pakpreo, Anghin, and Chantaboon. 



Colour (in life). The following description is of a specimen from 

 Pakpreo (which, it will be seen, diifers somewhat from Cantor's 

 Province Wellesley specimens) : — 



Upper surface of head, neck, body, and limbs yellowish olive- 

 green, a few small yellow spots on the neck ; the back has very distinct 

 black-ringed, round, bright yellow spots, on the posterior part of 

 the body these spots coalesce to form a dorso-lateral line of yellow 

 and black ; the fore hmbs are indistinctly spotted with yellow and 

 orange, the hind limbs very distinctly spotted with yellow. The 

 sides of body are rich dark blue, ^v-ith about eight large and several 

 small bright orange-red spots ; below the dark blue and orange 

 the sides are bright lemon-yellow, which merges gi-adually into the 

 pale grey of the belly. Lips and sides of head pale blue-grey, with 

 very faint orange spots. The underneath of head, neck, body, and 

 limbs very pale blue-grey. On the fore part of the thigh and on 

 the upper surface of the foot are patches of bright cobalt-blue. 

 Tail yellowish olive-green above, with numerous minute yellow 

 spots ; the sides are a hghter, brighter green and immaculate ; the 

 lower surface is very pale yellowish green. 



Size. The Pakpreo specimen, above described, measured in total 

 length 338 mm. (snt. to vnt. 120 ; tail 218). A specimen from 

 Anghin was larger, having snout to vent 152 mm., but a broken 

 tail.
