back are also hairy. Beneath, the membranes are hairy only in 

 close proximity to the vent and lower part of the body. 



In texture the fur is soft, thick, and cottony, and rather long, that 

 on the middle of the back being as much as 5 lines in length. 



On the upper parts the fur is tricoloured, as in the other mem- 

 bers of the group. That of the back has the base dusky, succeeded 

 by yellowish gre}'^ for the greater part of its length, and the remainder 

 rufous brown, with the exception of the extreme tips of the hairs, 

 which in the type specimens are paler and shining ; the general 

 colour of the fur of the upper parts, when undisturbed, being a dull 

 rufous brown, excepting that on the interfemoral membrane, which 

 is of a somewhat brighter rufous tint, and uniform in colour for its 

 whole length. 



The general tint of the under parts is palish brown, each hair 

 being reddish brown for the greater part of its length, with shining 

 tips of the same colour, but paler. The shining tips are most ob- 

 servable on the breast, and least so on the pubes. 



Mr. Hodgson's specimen differs only from the type specimen in 

 the absence of the shining tips to the fur. In both of these the 

 membranes are reddish brown, with the portions contiguous to the 

 bones of the wings somewhat diaphanous, and corresponding pretty 

 accurately with the red parts in V. formosus. 



The specimen from Amboyna differs so considerably in colour, 

 that it will be well to give a description of it separately. 



The interfemoral membrane has about twenty-four strongly marked 

 transverse dotted lines ; and about ten or twelve similar ones may be 

 seen on the base of the wings, parallel to the body. 



On the whole of its upper surface the interfemoral membrane is 

 clothed with hairs, but not very thickly, excepting on the os calcis, 

 which is thickly fringed, as are also the feet ; the membrane con- 

 tiguous to the back is also similarly furnished with hair. The under 

 surface of the membranes contiguous to the body, i. e. from the 

 axilla, by the flanks and around the pubes, is also clothed with hairs, 

 which thin off gradually, and are lost at the distance of a little more 

 than half an inch from the body. 



The whole of the fur is of the same peculiar texture observed in 

 the other examples, fine, and of medium length. On all the under 

 parts of the body it is purple-brown at the base, for a third of its 

 length, succeeded by purplish white, and tipped with bright rust- 

 colour. That which extends on to the upper surface of the mem- 

 branes is of a uniform rust-colour, and the face is wholly rust- 

 coloured. Beneath, all the fur is of a brownish-white colour, tinged 

 with rufous on the shoulders. 



The membranes are dark reddish brown, the interfemoral, and 

 those parts which are red in F. formosus, being of a lighter and 

 redder tint, but not so well marked as in that species. 



The following are the dimensions of these examples ; 1 . the type 

 specimen of Dr. Horsfield, 2. Mr. Hodgson's specimen, and 3. the 

 one from Amboyna : —
