thinks the same for he writes, “the Draco I must regard as a variety 
of D. maculatus, identical with D. haaszi, 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. maculatus 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 races 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. 
Head and body 105, tail 153 mm.
