a 
rostral by two scale rows; a median series of keeled scales with 
indistinct posterior diverging branches represented by two rows 
of keeled scales in each branch; occipital region with three 
differentiated scales, bordered by irregularly shaped, more or 
less keeled scales; a few large scales in a longitudinal row 
posterior to orbit; tympanum entirely hidden by small scales; 
thirteen upper labials (eleven on left side) ; no trace of nuchal 
crest; no enlarged or differentiated scales on neck; mental large, 
roughly triangular, not as long as rostral, but much wider; 
twelve lower labials; all scales on chin distinctly keeled, those 
along labials largest; back covered with irregular-sized, keeled 
scales; a few dorsolateral groups of enlarged scales; gular 
appendage distinctly developed, the anterior outline curving, 
the tip bluntly curved; near tip is a small spur about 1 milli- 
meter long, emerging about 1 millimeter from tip; lateral nuchal 
membranes strongly developed. Otherwise this specimen agrees 
with the type in scalation. 
Color in life.—Delicate yellow-green above; large paper white 
spots on back arranged in transverse lines; chin and underside 
of head pale greenish yellow; tip of gular appendage cream 
yellow; chin with cream dots; wings, above, blackish with nume- 
rous Narrow lines and small dots; below, uniform dusky, without 
spots. 
Adult male——This male specimen agrees more closely with 
the type than does the female just described. There are fourteen 
and fifteen upper labials; there is a small nuchal crest. The 
gular appendage is longer than in the type. 
Color in life-—Body yellow-olive above, mottled with areas 
of darker and lighter color, spots on back grayish white, in 
transverse rows. Wings, above, brown-red to brick red with 
narrow lines of minute cream dots; below, immaculate brown- 
red, growing purplish toward the outer, upper part; belly and 
underpart of limbs flesh color; gular appendage vivid orange 
yellow. 
Remarks.—The development of the gular appendage in the 
female is greater than that in any other Draco known in the 
Philippines. The small spur on the tip appears to be a normal 
development. The two specimens were shot from trees in heavy 
forest, in low mountains, at an elevation of approximately 300 
meters. No other specimen was seen.
