and bristle like. Over the eyes is a tuft which is nearly four lines in 

 length, and is very straight ; and above the nostrils is a similar fringe 

 of straight strong hairs, whilst the upper lips are margined similarly 

 with hairs which have a downward curvature and almost conceal 

 the mouth when it is closed. 



The upper surfaces of the ears are hairy only near the base ; and 

 the fur of the upper parts of the body does not encroach noticeably 

 upon the wing-membranes ; but the base of the interfemoral mem- 

 brane is a little hairy, and fine short hairs are scattered along the 

 upper surfaces of the tail, tibia, and feet. The free portion of the 

 edge of the interfemoral membrane, between the os calcis and end 

 of the tail, is also slightly fringed with fine short hairs. 



The fur is fine and woolly in texture, and very long ; that of an 

 example in the Museum of the East India Company, from Calcutta, 

 attains as great a length as four lines on the dorsal region. It is 

 bicoloured both above and beneath. On the whole of the upper 

 parts it is dusky at the base for nearly two-thirds of its length, with 

 the terminal third brown (nearly of the same tint as the back fur of 

 Vesp. Baubentonii, but a little more tinged with rufous). Beneath, 

 it is dusky at its base, tipped with yellowish-brown. Such is the 

 colour of the specimen alluded to, presented to the Company's Mu- 

 seum by Mr. Pearson. A specimen in my own collection, taken in 

 Ceylon by Mr. Thwaites, appears to exhibit the usual differences 

 which exist between the animals of that island and the mainland of 

 India. It is smaller and darker in colour, but is otherwise similar 

 to the Calcutta specimen. The membranes are of a medium brown 

 colour, darker in the Ceylon specimen.

I can detect no difference in the position or proportions of the 

 teeth in this species from those of K.picta.
