No gular pouch ; the openings of small pores appearing beneath 

 the fur covering the inferior surface of the lower jaw between its 

 angles ; in some male specimens the hair in this situation is very 

 long, forming a dense black beard*. Eadio-metacarpal pouch large. 



Wings from the tibiae above the ankles. 



The fur of the head extends upon the face as far as a line joining 

 the inner comers of the eyes ; the inner side of the ear-conch is 

 covered with a few hairs ; posteriorly the ears are clothed at their 

 bases, naked above except where a row of fine hairs fringe the outer 

 margin. 



On the upper surface the fur of the body extends upon the wing- 

 membrane about one third the length of the humerus and femur, 

 the remainder of the wing- and antebrachial membranes are quite 

 naked ; posteriorly the interfemoral is covered thinly almost as far 

 as the point where the tail perforates it ; inferiorly, the fur of the 

 body extends outwards upon the wing-membrane as far as a line 

 joining the middle of the humerus and femur ; beyond this, as in 

 other species, a band of very short fine hair extends along the 

 posterior margin of the forearm to the carpus ; the feet are naked, 

 except where a few hairs arise at the base of the claws on the backs 

 of the terminal phalanges of the toes. 



Above, the fur is white at the base, then dark brown, the extreme 

 tips slightly greyish ; beneath, white at the base, then paler brown 

 than on the upper surface, the extreme tips greyish. In some 

 specimens the white at the base of the hairs beneath is not well 

 marked. 



The black beard is not always developed in the males ; its deve- 

 lopment seems to depend on certain conditions as yet not known ; 

 probably it appears periodically during the rutting-season. In five 

 male specimens in the Indian Museum this beard is well developed, 

 while out of over one hundred specimens received by M. Milne- 

 Edwards from Cochin China, examined by me in the Paris Museum, 

 two only possessed the beard. 



The females of this species (in which neither the black beard nor 

 pore-openings are developed) resemble those of T. longimanus ; they 

 are readily distinguished, however, by the absence of the rudi- 

 mentary gular sac, and by the under surface of the lower jaw being
