the middle of their outer margins; tragus narrow and tapering to 

 an acute point, which is directed outwards ; its outer margin has a 

 notch near the base. 



Wing-membranes extending to the base of the toes; the latter 

 longer than the remaining part of the fool ; thumb with the free 

 portion much longer than thai which is engaged in the membrane. 



The fur of the forehead, which is very thick, extends uninter- 

 ruptedly to halfway between the end of the nose and the eyes; all 

 the side of the face from the root of the car to the Bnonl is naked, 

 with the exception of a tuft of -till' hairs in front of the eye and a 

 moustache on the opper lip. The ears are a little hairy at the bas ! 

 of their hinder surface, and the fur of the hack encroaches a little on 

 the interfemoral membrane. 



Everywhere the fur is very thick, soft, and cottony, with very 

 little gloss. That of the upper parts is tricoloured, and that of the 

 under surface bicoloured. 



On the top of the head and the whole of the hack it i^ blackish 

 brown at the hase for a fourth of its length, succeeded by yellowish 

 huff, and tipped with light rust-colour, the latter prevailing most on 

 the shoulders and on the interfemoral membrane. All the under 

 parts have the fur dusky at the hase for half its length, the re- 

 mainder heing pale buff, and it is so thick and close as to appear 

 wholly of the latter colour unless it he moved. 



Individuals vary considerably in the hue of the rust-coloured and 

 buff portions of the fur, so that their general appearance may be 

 either light reddish buff-colour, or a medium brown ; but in either 

 case the bicoloured and tricoloured character of the fur is main- 

 tained. 



The specimen of V. emarginatua, which formed part of the Italian 

 collection of the late Prince C. L. Bonaparte, having been presented 

 by him to me during a stay in Paris in the spring of L857, I am 

 enabled to correct an error into which I had fallen, with some other 

 zoologists, in regarding it as referable to V. Nattereri, It is un- 

 questionably the V. emargmatua of Geoffroj. This specimen, pre- 

 served as a skeleton, but a good deal injured, supplies the following 

 details respecting the dentition* : —
