• The specimen agrees in all respects with the description of 

 G. doriae except that the nuchal and dorsal crests are not so 

 high. The nuchal crest at its highest is not more than half the 

 diameter of the orbit, and from there it gradually diminishes 

 in size as it proceeds backwards. The sex, however, may be 

 sufficient to account for this difference. The tympanum 

 is about three-quarters the size of the eye opening. 



In colour the lizard is greyish -blue (probably green in life) 

 above and on the sides, with black spots and reticulations; the 

 gular fold is black and the tail has broad black annuli ; the belly 

 is whitish. 



To G. doriae also I refer two j^oung specimens recently 

 obtained by my native collector at Batang Star, Patani, in 

 Peninsular Siam. They differ in having a series of from two 

 to four enlarged and differentiated, slightlv keeled scales, on 

 either side of the back. In these juveniles the gular sac is 

 marked with black streaks and there is some black mottling on 

 the belly ; the tail has indistinct dark annulations. 



G. ahhotti Cochran ^Proc. U.S. Nat. Mus. 1923, No. 2421, 

 p. 1) described from 'a female example obtained in Peninsular 

 Siam may ultimately have to be referred to doriae. Its des- 

 cription fits my specimen well but the fact that mine camfe 

 from the region where all the specimens of G. doriae known 

 have been obtained, inclines rae to refer it to the older name.

3 specimens from Mt. Gadiu. 



Thirty scales round the middle of the body in each example. 

 One has a fairly well marked dark brown Hght-edged lateral 

 band beginning at the eye, in another it is just discernible, 

 while in the third it is entirely absent. In this last specimen 

 the sides of the throat are marked with dull orange.
