Ears rather narrow, conical, and obtusely pointed, very similar in 

 shape to those of Pt. samoensis, scarcely as long as the muzzle, half 

 the concave surface of the conch thinly clothed with soft hairs. 



Interfemoral membrane narrow in the centre, concealed by the 

 fur ; wings from the sides of the back. 



Face in front of the ears shining yellowish brown intermixed with 

 black hairs ; crown of the head silvery grey ; back of the head, neck, 

 and shovdders bright yellowish buff in male, pale buff in female ; 

 back black, intermixed with a few shining grey hairs, the dark 

 colour commencing abruptly, and contrasting strongly with the 

 bright-coloured fur of the neck ; beneath, the chin and throat are 

 black, the neck bright reddish yeUow intermixed with black, 

 breast and abdomen black, the extremities of many hairs shining 

 grey. 



Fur moderately long and dense ; on the upper surface the anterior 

 extremities are nearly naked, but the thighs are covered ; the fur of 

 the back short, appressed, occupying a space across the loins about 

 two inches wide ; beneath, the wing-membrane is covered rather 

 thickly by moderately long fur as far as a line drawn from the outer 

 third of the humerus to the knee, terminating abruptly ; the thighs 

 are thickly covered, and some hairs extend upon the tibiae. 



The greater number of adult specimens of this species are distin- 

 guishable by the above characters, but in others, examples either of 

 not full-growTi or very old individuals, with fur characteristic of 

 different seasons or of different localities, the colour, quality, and 

 distribution of the fur are slightly different ; and these differences 

 have chiefly led to the large number of synonyms which are brought 

 together in the above list. 



In a young female specimen from Samoa the head, back, and under 

 surface are very dark brown (appearing quite black in alcohol), the 

 back of the head, neck, and shoulders pale reddish yellow ; the interfe- 

 moral membrane is about a quarter of an inch deep in the centre, where 

 it is clothed with long fur, which also extends laterally as far as a 

 line drawn between the middle of the tibiae ; the tibise are almost
