Very similar to the preceding species in the general form, hut 

 distinguished hy its conspicuously smaller size, proportionately 

 longer and broader ears, by the distribution and colour of the fur, 

 by the position of attachment of the wing-membrane, which arises 

 from the sides of the body comparatively closer to the spine, and by 

 the less development of the interfemoral membrane in the centre. 



The fur of the body is longer than in Ft. edulis, especially on the 

 back and on the interfemoral membrane, and extends further along 

 the posterior extremities ; but on the wing-membrane beneath, be- 

 tween the anterior and posterior extremities, it is much shorter than 

 in that species. 



Face and throat reddish brown ; crown of the head brighter 

 reddish brown ; nape of neck and shoulders varying from bright 

 reddish yellow to pale buff; back dark reddish brown (colour of 

 cocoanut-fibre), becoming lighter towards the rump ; under surface 

 of neck, and the greater part of the breast and abdomen, varying 

 from bright bay to pale reddish yellow ; sides of the body beneath 

 the wings and round the pubis dark reddish brown ; on each side 

 of the neck a circular tuft of rigid unctuous hairs, of a reddish- 

 yellow colour, covering glands, as in Ft. edulis. 



Teeth as in Ft. edulis ; the skulls, also, of the two species are 

 scarcely distinguishable except by size, those of immature specimens 

 of Ft. edulis with bifid sagittal crest are considerably larger than 

 skulls of old individuals of this species. 



In one of the types of Ft. leucocepTiahts, Hodgson, _ from Nipal, 

 there is an abnormal additional upper molar immediately behind 

 the third molar, about the size of one of the outer lower incisors, the 

 antepenultimate molar (the last molar in all other specimens) being 

 similar to the corresponding tooth in other examples of Ft. medius,
