Cvlour{ 2 ad., Barit, jS^. Luzon, teeth Romewhat worn, 95.8.2.4). — 

 Jkck and rump nearlj' seal-brown, somewhat tinged with burnt- 

 umber on rump, distincUj- glossy, and everywliere tincly powdered 

 or " fro.sted '" with .silvery greyish. Individual hairs finely crinkled, 

 producing the impression of a narrow annulation of the hairs. — 

 Breast, belly, and flanks nearly seal-brown, not glossy, conspi- 

 cuously mixed with longer, coarser yellowish buff hairs, particularly 

 along middle of underside, and everywhere thinly sprinkled with 

 highly glossy silvery white hairs. — Mantle chestnut, shading to 

 chocolate on sides of neck, this again to chocolate seal-brown on 

 foreneck ; extreme bases of hairs blackish on mantle and foreneck, 

 yellowish on sides of neck. Chocolate colour of sides of neck 

 extending forward so as to encircle base of ears. — Crown, as far 

 forward as a line between eyes, occiput, and narrow median portion 

 of nape of neck light yellowish buff tinged with orange-ochraceous 

 posteriorly on nape, forming a large sharply defined nuchal patch 

 strongly contrasting with dark mantle, sides of neck, and face ; 

 bases of hairs of nuchal patch blackish. Muzzle, circumocular 

 region, sides of face, chin, and throat nearly uniform glossy 

 blackish. 



Individual variation of colour. — Chiefly confined to the more 

 blackish or more dark brownish tinge of the back, the thinner or 

 tliicker sprinkling of the underparts with pale hairs, the blackish 

 or chocolate tinge of the foreneck, and the more buflfy or more 

 orange tinge of the nuchal patch. — Back generally more or less 

 typically seal-brown, but in some specimens tinged with, or closely 

 approaching, burnt-umber (perhaps sun-burnt pelage). General 

 colour of breast, belly, and flanks sometimes dull, in other specimens 

 warm and .slightly glossy, seal-brown, in certain lights with a faint 

 tinge of dark maroon ; there is every transition (in specimens from 

 the same island) from a very thin to a rather thick sprinkling of 

 this colour with coarse bufl'y hairs. Foreneck in most specimens 

 washed with dark chocolate or chestnut, but sometimes (and quite 

 independent of the locality) blackish like chin and throat. Nuchal 

 patch varying from nearly cream-buff, through buff, to yellowish 

 buff, generally (]]ot always) tinged with ochraceous buff on nape. 



The variations of the colour, as here described, are independent 

 of age, sex, and locality ; practically all variations are represented 

 in a series of specimens from Luzon. Closely similar variations are 

 seen in the non-melanietic races of Pteropus vampi/rus.
