very little elevated ; the nostrils small and near together, with the 

 space between them slightly depressed rather than emarginate. The 

 glands of the upper lip do not approach very closely to the edge of 

 the latter, but pass backwards over the eyes almost to the front mar- 

 gins of the ears, and leave a central longitudinal depression along the 

 face, up the middle of which is a narrow raised ridge, producing, to 

 use the words of Mr. Waterhouse, " two longitudinal grooves." 

 The ears are very similarly shaped to those of F. formosus, but I 

 think a little less emarginate. The tragus has a distinct tooth or 

 lobe at its outer margin, close to the base, above which is a consider- 

 able indentation, succeeded by an obtuse angle, from which it passes 

 in a straight line to the tip, which is tolerably acute. The inner 

 margin is nearly straight. Both the ears and tragus, when ex- 

 amined by transmitted light, appear to be glandular in structure. 



The feet are large ; the toes occupying fully two-thirds of their 

 entire length. The as calcis takes up two-thirds of the distance be- 

 tween the foot and the end of the tail ; the latter wholly enclosed in 

 the interfemoral membrane. The middle phalange of the thumb (as 

 in all others of the group) long, the basal one short. 



The fur on the top of the head is thick, but does not extend so 

 near to the end of the nose as in V. formosus. On the space around 

 the eyes are some irregular tufts of longish hairs, and the upper lips 

 are furnished with moustaches of bristle-like hairs ; and all the upper 

 surface of the snout, from above the nostrils to the fur of the fore- 

 head, is similarly studded with short bristly hairs. 



The fur on the back extends on to the base of the interfemoral 

 membrane for a fourth of its length, and along the tibiae to the 

 upper surface of the feet, the outer toe * being furnished with short 

 bristly hairs on the whole of its upper surface, and the others hairy 

 only on their terminal and subterminal phalanges. The interfemoral 

 membrane has a series of similar short hairs on the whole of its 

 hinder margin. 



On all the upper parts the fur is close, firm in texture, and bi- 

 coloured ; light dusky grey at the base, with the tips yellowish buif. 

 Below, it appears to be unicoloured, huffy ash, with a strong tinge of 

 yellow about the axilla. 



It is probable that the fur would be more markedly bicoloured in 

 older examples, as we see in other species that the colours of young 

 specimens are much less distinct than in older ones. 



The membranes are marked precisely as in V , formosusy and re- 

 quire no further notice.
