DRACO 125 



Adult female. — The female differs from the male in being 

 larger and more heavily built; the nostrils are directed more 

 nearly upward than outward; the rostral is prominent, rugose; 

 the Y-shaped marking is prominent, the anterior part forming a 

 straight keel ; supraocular region is wider, and the line of scales 

 on the superciliary edge is not so prominent or continuous; 

 the occipital scales are rather regular and large ; there are eleven 

 upper labials, the last three times as large as the preceding ; there 

 are five or six rows of scales between labials and orbit; there 

 is no enlarged subocular series as in males, and the postorbital 

 series which extends to above tympanum is prominent, composed 

 of two much-enlarged scales; this series is touched by a series 

 of smaller scales which border the posterior part of the tem- 

 poral region; the tympanum is rather depressed, and covered 

 with small scales; the lateral gular appendages are smaller; 

 there are two small, spinelike scales above and slightly posterior 

 to tympanum, there is a slight trace of scales on back, rather 

 irregular, the seven median rows largest, and their keels form 

 continuous rows ; a distant row of keeled scales is prominent on 

 each side, separated by eighteen scales at the greatest width; 

 hind leg reaches axilla. 



Color in alcohol. — (Freshly preserved.) Above mottled and 

 variegated, bluish green, olive, to grayish brown, to lavender, with 

 darker variations, a distinct series of brown horseshoe markings 

 on the back, and a series of darker brown markings along the 

 outer series of keeled scales on sides; a distinct nuchal, black- 

 brown spot and a very prominent interorbital black spot; ra- 

 diating dark lines from orbit; labials dimly barred with dark; 

 anterior part of head mottled brown with a dim transverse 

 stripe passing through interorbital spot; usually a light line 

 below orbit and an indistinct lighter spot behind orbit; wing 

 membranes black with traces of grayish transverse broad lines, 

 and numerous narrow, elongate, grayish spots forming curved 

 lines running longitudinally; outer part of wing darkest with 

 scattered grayish spots ; wings below with a yellow wash and a 

 few outer dark spots; chin light, peppered with brown; an oval 

 white spot on the very slight gular fold; belly iridescent with- 

 out spots. 



Variation. — The dorsal scales vary in size; the distinctness 

 of the keeled outer row of scales also varies, being indistinct 

 in certain specimens and prominent in others. The color pat- 

 terns on back vary greatly, but the nuchal spot is always 

 present.
