REPTILIA. 
Draco volans (Gray, Cat. Brit. Mus.). 
Draco Daudinii (Dum. et Bib.). 
Var. A. — Colour — above; coppery brown, mottled in different 
shades — below ; whitish brown, with a metallic gloss, blueish gray 
down the centre of the belly ; the chin and, in some specimens, the 
flanks being faintly marked with transverse dark mottled lines; 
when fresh, the dying membranes or wings are brilliant crimson ; 
this colour becomes dull orange-red in specimens preserved in 
ispirits ; the wing is fringed at the outer edge with brown, within 
which is a margin of large black spots ; the surface of the membrane 
is also transversely spotted with black. On the head, between the 
eyes, is a large rounded black spot, and on the nape is an oval spot 
of the same colour ; three fainter and smaller spots also occur about 
half way down the neck in a transverse position. 
Var. B.- — Instead of the brown colour with which the former 
variety is marked, this Draco is mottled with light and very dark 
green, the markings also being more distinct. 
In the brown varieties the pouches on the sides of the throat are 
marked and prominent, while below the throat the pendant pouch 
is wanting, the skin being merely enlarged and wrinkled. In the 
green variety the lateral pouches are as in Var. a. and the gular 
pouch is very large, pendant and pointed, and of a yellow colour. 
Tail very slender. 
Both the varieties agree in their comparative dimensions, and the 
dimensions of one (Var. b.) are as follows - 
Total length, 7 inches 2^ lines. 
Length of tail, 4 inches 4 lines. 
„ of ear to end of muzzle, 6 lines. 
The gular wattle depends from the throat, 6 lines. 
These beautiful little Lizards are frequently met with in 
Labuaii, and sometimes keep together in companies of six or 
seven. When on the wing they might also be almost mis- 
taken for large butterflies ; though they move their wings, how- 
ever, their flight never rises, but is always to a lower point. 
They rest upon the trunks of trees, tail downwards, and while 
at rest the yellow fold of skin under the throat is frequently 
inflated, giving them a very odd appearance. The Malays 
are much afraid of them, believing them to be venomous, and 
assert that they will bite men in the back of the neck, causing 
death.
