Hab. Unknown. 



Type in the collection of the Leyden Museum. 



The position of this very remarkable species in the genus is diffi- 

 cult to determine. While resembling the species allied to Pt. vulgaris 

 in the quality of the fur and in the short ears, it differs from them 

 altogether in the nakedness of the extremities, and agrees in dentition 

 most closely with i^. aneiteanus and Pt.juhatns. 



9. Pteropus poliocephalus. 



Pteropus poliocephalus, Temminck, Monogr. Mmnmal i. p. 179 (1827). 



Nearly as large as Pt. gouldii, and with similarly long and pointed 

 ears, but differing remarkably from that species, as well as from every 

 species of the genus of the same size, in the quality, colour, and dis- 

 tribution of the fur. 



Ears much longer than the muzzle ; the upper third of the ear- 

 conch narrow, subacutely pointed, and concave beneath the tip, which 

 is inclined outwards ; the concave surface clothed with fine hairs. 

 Interfemoral membrane very narrow in the centre, concealed by the 

 fur. 



Fur everywhere long and dense, extending thickly upon the face 

 and upon both sides of the legs, above to the ankles, beneath as far 

 as the ends of the tibiae ; fur of the back directed posteriorly and 

 slightly appressed, occupying a space quite three inches wide across 

 the loins, short but dense on the arm and muscular part of the fore- 

 arm, on the legs and rump woolly ; beneath, the whole membrane 

 between the humerus and the thighs is covered ; fur nearly two inches 

 wide behind the elbow. 



Fur of the head grey with a yellowish tinge, the base of the hairs 

 dark brown or black ; neck and shoulders and anterior part of the 

 breast bright reddish yellow ; breast from shoulder to shoulder blackish 

 grey, some of the hairs with yellowish extremities ; middle of the 

 lower part of the chest and abdomen black at the base, the terminal 

 third of the hairs shining yellowish grey ; back greyish black, 

 many of the hairs with shining extremities ; the fur covering the 

 interfemoral membranes and legs of the same colour as on the 

 abdomen. 



Teeth rather narrow, like those of Pt. medius ; the first lower 

 premolar smaller than the last molar, in the centre of the space 

 between the canine and second premolar; first upper premolar 

 minute, scarcely visible ; lower incisors small, the inner pair half the 

 size of the outer and slightly separated. 



Length, head and body 8"-5, head 2"'8, ear from end of nostril 

 2"-3, eye from end of nostril 1"-1, ear l"-45 x 0"-7, forearm 6"-2, 

 thumb 2"-5 ; third finger— metacarp. 4", 1st ph. 3"-15, 2nd ph. 4"-8 ;
