2. PTEROPUS. 49 



Comparison of the above measurements shows that while this 

 species exceeds Pt. chi-ysoproctus very considerably in the length of 

 the muzzle, ears, forearms, tibiae, and feet, the latter has the bones 

 of the middle finger longer. This could not be the case if Pt. ptero- 

 notus represented only the more adult form of Pt. chrysoproetm, for, 

 m all Bats, while the ears and feet attain their full size when the 

 animal is still young, the bones of the wings are the last parts of 

 the body to reach their full length. 



This species, therefore, differs from Pt. chrysoproctiis, to which it 

 is most nearly allied, in the greater length of the parts referred to 

 above, in the different colour of the fur, in the narrower and much 

 longer muzzle, in the presence of the small first upper premolar in 

 adult individuals, and in the remarkable development of the inter- 

 femoral membrane behind, which is equalled only by Pt. edulis from 

 the same locality.

Pteropus funereus, Temminch, I. c. ii. p. 63 (1835-41). 



Ears much longer than the muzzle, naked, acutely pointed ; the 

 length of the ear- conch nearly double its greatest width, the upper 

 third of the outer margin concave beneath the tip. 



Wings from the sides of the hairy back, quite 2 inches apart at 

 their lines of attachment ; interfemoral membrane about an inch 

 deep in the middle, not concealed by the fur. 



Back of the head,' neck, and shoulders clothed with moderately 

 long and dense erect fur ; from the shoulders backwards the fur is 

 short, closely appressed, and directed backwards, occupying a space 

 (in full-grown specimens) nearly 4 inches in width across the 

 middle of the back. The extremities are nearly naked ; a narrow 

 line of very short fur passes outwards upon the wing-membrane 

 behind the humerus for about half its length, and a few short hairs 

 cover a narrow portion of the wing-membrane along the posterior 

 margin of the forearm. The thighs, and the interfemoral mem- 

 brane as far as a line corresponding to the position of the semi- 

 circular band on its inferior surface, are thinly covered, the poste- 

 rior free margin of the membrane is quite naked. On the under 

 surface the wing-membrane is covered with thinly spread rather 

 long fur, which extends outwards as far as a line drawn from the 

 knee to a point about 1 inch posterior to the elbow, thence behind 

 the forearm for two thirds its length ; the thighs are partially 

 covered, the legs and the interfemoral membrane are quite naked. 



Colour of the fur variable, brighter in males than in females, 

 generally dark reddish brown on the face and under surface ; head
