Note by Mr. Annandale : — " The male of this species dances iu 

 a conspicuous position before the female, which remains concealed. 

 He is then of a pale yellowish flesh-colour, with a conspicuous 

 black smudge on each side of the gular pouch, which is much 

 dilated. He stands with the fore part of the body raised on the 

 fore legs, and bows bis head slowly and repeatedly, opening and 

 shutting his mouth continually ; after a time he advances a few 

 steps towards the female and repeats the performance. If disturbed 

 the black marks disappear. The males fight very readily with one 

 another, and change colour as they do so ; the victor becomes of 

 a warm reddish bro\A'n. This species is common as far south as 

 Biserat, less so in Eaman, and I did not meet with it at all 

 farther south."

This species is fairly common at Patalung, but grows rarer 

 towards the south, and probably does not range beyond Patani.

Mr. Annandale has given me the following notes concerning this 

 species: — "The commonest species of lizard in the barren stretches 

 of sand which are common in Lower Siam near the sea-coast, on 

 the east side of the Peninsula. It is exceedingly active and very 

 timid. Though its colour is brilliant, the green and grey ' eyes ' 

 which ornament its back, and the orange and purple stripes on its 

 side, are not conspicuous amidst its natural surroundings : the 

 former harmonizing with the shadows cast on the sand by the 

 scanty vegetation which it supports ; the latter are more or less 

 concealed by the fold into which the skin that covers the ribs 

 naturally falls. When the male, which is more brilHant than
