.30 ZOOLOGY OF THE VOYAGE OF THE SULPHUR. 



The silvered Kalong — Pteropus argentatus. 



Pteropus argentatus, Gray, List Mam. Brit. Mus. 194. 



Black-brown. Back very minutely grisled. Under-side with some longer silver-tipped hairs. 

 Head slightly washed with yellow, especially on the temple and orbits. Side of the fore- 

 head, nape, and back of the neck, bright golden yellow. 



Inhab. Amboyna?? 



The hair of the back of the neck is black-brown at the lower half of its 

 length, the black of the face forms a streak up the middle of the forehead. The 

 under-side of the fore-arms and the wings, near the fore-arms and sides of the body- 

 are hairy. The thigh rather hairy. The ears moderate, rather acute, exposed. The 

 silver-white tips to some of the longer hairs of the under-side, give a peculiar 

 appearance to this species, and render it distinct from all the varieties of P.J'une- 

 reus, described by Temminck.

 the back.
