deutition and in the free last caudal vertebra; but it is readily dis- 

 tinguished by the straight outer margin of the ear-conch, by the 

 colour and distribution of the fur, and by the large number of caudal 

 vertebrae. 



Type in the collection of the Indian Museum, Calcutta.

Ears shorter than the head, obtuse, rounded off above ; the inner 

 margin of the conch very convex in the lower half, straight in 

 upper, iipper third of the outer margin concave beneath the obtuse 

 extremity, then convex, emarginate opposite the base of the tragus, 

 terminating in a convex lobe, the upper margin of which is not 

 notched ; the tragus reaches its greatest width about the middle of 

 its inner margin, then sloping inwards to form with the inner 

 margin an acute angle ; inner margin slightly concave, a rounded 

 lobule at the base of the outer margin ; nostrils scarcely projecting, 

 opening sublaterally with a concave space between. 



Wings from the base of the toes ; no postcalcaneal lobe ; half the 

 last caudal vertebra free. 



The fur is very peculiar and characteristic of the species. Above, 

 intensely black, the extremities of some of the hairs bright ferrugi- 

 nous, more apparent by reflected light ; beneath, duD black ; the ex- 

 tremities of most of the hairs shining greyish or ashy ; fur very long 

 and very dense, extending upon the face in front of the eyes, leaving 

 the terminal third of the muzzle half naked; the base of the ears 

 behind covered, a small tuft of hairs in front of the base of the 

 trao-us. Wings almost naked, no band of hairs posterior to the fore- 

 arm ; the basal third of the upper surface of the interfemoral mem- 

 brane with rather short black hairs ; legs naked. 



Integument black. Temminck mentions that the black ears are 

 margined by white, but I have not observed the white border in the 

 type in the Leyden Museum ; it is probably more apparent in recent 

 specimens. 



Upper incisors like those of the Serotine ; the inner incisors long 

 and strong, faintly bifid at their extremities ; the outer incisor on 

 each side very small, close to the outer and anterior part of the base 

 of the inner incisor, with a weak oblique cusp ; first upper premolar 

 very small, in the inner angle between the closely approximated 

 canine and second premolar ; lower incisors at right angles to the 

 direction of the jaws. 



Skull slightly vaulted and raised above the face-line ; a rather 

 deep longitudinal groove in the frontal, with prominent but short 

 and blunt postorbital processes. 



Leno-th (of the type specimen), head and body about 2"-4, tail
