PTEROPODID^. 



4. Pteropus formosus. 



Pteropus formosus, Sclater, P. Z. S. 1873, p. 193, pi. xxii. (not de- 

 scribed). 



Ears scarcely longer than the fur, naked ; muzzle as in Pt. 

 dasymallus ; interfemoral short, concealed by the fur. 



Fur dark brown above and beneath, the extremities of many hairs 

 grey ; neck in adult male bright yeUow or white, with a slightly 

 yellowish tinge, very distinct from the surrounding dark-coloured 

 fur ; the collar divided beneath by a narrow but weU-defined band of 

 black hairs extending backwards from the throat to the breast ; in 

 the female the coUar is marked only by the fur being somewhat paler 

 in colour round the neck. Pur everywhere (except on the muzzle) 

 long and soft, extending upon the forearms and upon the tibiae to 

 the ankles, though not so densely as in Pt. dasymallus ; beneath, the 

 thighs are covered and part of the tibiae. 



The above description has been taken by me from an inspection of 

 the only specimens of this species as yet obtained, which are still 

 living in the gardens of the Zoological Society of London. The ears 

 are much injured (as I have always observed to be the case in Bats 

 living in captivity), and a correct description cannot therefore be 

 made of them, but they appear to be quite naked, rounded, and 

 scarcely longer than the fur. Their size appears to correspond to 

 that of Pt. dasymallus, to which species they are evidently closely 

 allied ; but the very distinct white collar (yellow when the specimens 

 were first obtained) in the male and the weU-markcd dark band 

 dividing it below distinguishes it from Pt. dasymallus. Other more 

 important differences may be discovered in the form of the ears and 

 in the dentition when more specimens are obtained, and I agree with 

 Mr. Sclater in considering the Pormosan Pteropus distinct from the 

 Japanese Pt. dasymallus. 



The type specimens now living in the gardens of the Zoological 

 Society appear to be about the size of Pt. dasymallus. 



5. Pteropus pselaphon.

Monogr. Mammal, ii. p. 70 (18.35-41).

 Pselaphon ursinus. Gray, Catal. Monkeys and Fruit-eating Bats, 



p. 110 (1870). 



Ears short, sub acutely pointed, half concealed by the long fur of 

 the head, but broader at the basal third than in Pt. dasymallus, and 

 more attenuated towards their extremities, the basal half of the 

 ear-conch thinly clothed with moderately long hairs ; head broad, 

 rather abruptly narrowed in front. 



Posterior margin of the very narrow interfemoral membrane con- 

 cealed by the fur. Pin: everywhere long and dense, dark reddish 

 brown throughout, some of the hairs of the back shining or greyish 

 yellow, and, in some specimens, those of the ventral surface also ; the 

 fur of the back long, like that of the neck, extending thickly upon
