Pteropus capistratus. 



Of this species fifteen specimens were examined, five of these hav- 

 ing a length of forearm of 100 mm. to 105 mm ; seven of 65 mm. to 80 

 mm. and three of 50 mm. The three last named were certainly im- 

 mature. 



(1) Crorvn with median black line, the remainder being white. 

 The' black line distinctly divided anteriorly on dorsum of muzzle. 

 The eye surrounded with white hair which is directed backward 

 and merges into that of the crown. 



An oblique black line extends across the face from near the inner 

 canthusto the angle of mandible. Directly in front of the whisker 

 a vertical black line extends. It broadens slightly and merges with 

 the black of the front of the neck and space between the horizontal 

 rami of the lower jaw. In the space last named the hairs are arranged 

 in the form of two lines with a white space between. 



Side of neck white not longer than back. The occiput yellow- 

 white. 



Base of hair of occiput, side, front and back of the neck black. The 

 white hair of the crown and the side of face including the Avhisker 

 unicolored. 



No differentiation at the base of prebrachiuiii. 



The color of the chest and abdomen dark brown with ashy or pale 

 yellow-white tips. Side of body or color of arm scarcely differen- 

 tiated. The space about nipple nearly naked (sexes not distin- 

 guished). 



Back much the same, but hair slightly appressed. Margin lighter 

 as in P. vulgaris. Sacrum and legs to ankle markedly woolly. 



Free margin of endopatagium hairy ; white hair on dorsum, arm 

 and forearm. 



(2) Same as above with white tips supplanting the yellow- 

 white of the nape of the neck and the occiput. 



(3) Same as above, everywhere darker, the base of the hair becom- 

 ing conspicuous owing to the partial absence of the apical white. 

 Black lines on the face absent except the median dorsal of the crown. 

 The whisker light, uniform gray. The hair about eye and on crown is 

 also gray but darker than the foregoing and is furnished with a dark 

 brown base. The dark brown of the space between the horizontal 

 rami of the mandible confined to the postmental space. 



(4) The very immature individuals have entirely white hair on 

 back of neck.
