DRACO 121 



in having the tympanum scaled, nostrils pointed directly out- 

 ward, and a few larger spots on the outer part of the wings. 

 There are about twenty-five scale rows between the enlarged 

 outer rows of keeled scales which are not very distinct. 



Female. — For the most part the females are larger than the 

 males, and markings and coloration are entirely different. The 

 following is a color description of a large female in alcohol 

 from the collection of W. Schultze, Manila, collected at Mon- 

 talban, Luzon: Above variegated olive to grayish brown; 

 body traveirsed by three prominent, variegated, irregular, darker 

 spots; the line of enlarged scales on either side of body darker 

 olive brovmish; one spot across shoulders and a very strong 

 nuchal spot; head dull bluish gray or very light ultramarine, 

 with a transverse; bar across head and supraorbital regions; 

 snout blackish; numerous blackish flecks on sides of head and 

 neck; wing membranes black with whitish spots on inner part 

 and with very narrow diagonal stripes of whitish; below throat 

 brownish with dark specks; belly pale ultramarine; wing mem- 

 branes below with a large outer dark area and numerous smaller 

 blackish spots; forelegs transversely barred, and hind legs 

 and toes spotted or barred with darker; base of tail with trans- 

 verse bars. 



A second adult female from the same collection is marked 

 similarly, save that the back is rather coppery brown, with more 

 or less metallic iridescence, and the light spots are almost en- 

 tirely wanting on the wing membranes. Two young females 

 have the dark interorbital stripe merged into the dark color of 

 the anterior part of forehead; the light spots on inner part of 

 wing membranes are contiguous, forming more or less distinct 

 transverse lines; transverse marks on back are very distinct; 

 one is of coppery brown. A very young female (jneasuring, 

 snout to vent, 30 millimeters) has the wing membranes whitish 

 with a large outer dark spot, and numerous scattered dark spots 

 arranged in transverse rows, thus approaching the markings 

 of the male. 



In the species there appears to be a number of regional varia- 

 tions which ^t first I was inclined to regard as worthy of sub- 

 specific distinction; with examination of a larger series of 

 specimens I find that in these regional groups there is also 

 certain variation which would tend to break down the distinc- 

 tions drawn between the various groups. The chief distinctions 

 are as follows:
