thinks the same for he writes, " the Draco I must regard as a variet)'^ 

 of D. maculatus, identical with D. haasii, of which we have one of the 

 types from Siam," 



We have therefore here accorded it subspecific rank, as it 

 differs distinctly, both by its smaller size and by its colouration from 

 the usual form of D. macnlatus met with. A further series of 11 

 specimens, obtained since at Muak Lek and Pak Jong in the Dong 

 Rek Mountains, confirm our ideas.

9. ACANTHOSAURA CRUCIGERA, Boulenger. 



A single female of this slightly differentiated race of A. armata 

 was obtained on Koh Chang. 



The close connection between the two race? as defined, is shown 

 in this example by the presence of twelve labials, and a tail only one 

 and one half times as long as head and body. A slight, though dis- 

 tinct gular fold is present.
