the extremity of the nose alone uncovered. On the upper surface 

 the wing-membrane is covered as far as a line drawn from the 

 middle of the humerus to the knee-joint, terminating by a well- 

 defined margin ; and the interfemoral in a similar manner about as 

 far as the end of the third caudal vertebra ; beneath, the wing- 

 membrane is clothed as far as the elbow, but the interfemoral is 

 naked except at the root of the tail. 



Pur above deep brownish chestnut ; beneath similar, with a 

 greyish tinge ; the base of the hairs on both surfaces dark. 



Second upper premolar slightly internal.

Hah. Brazil. 



This species is at once distinguished by its very peculiar dense woolly 

 fur, which covers the face as thickly as the other parts of the body.

Muzzle narrow and conical ; glandular prominences between the 

 eyes and nostrils forming raised ridges enclosing a triangular con- 

 cave space on the face behind the nostrils. Ears long, laid forwards 

 the tips extend to the end of the muzzle or slightly beyond it ; 

 internal basal lobe angular in front, its horizontal margin joining 

 the ascending inner margin of the ear slightly under a right angle ; 

 lower third of inner margin straight, middle third convex, upper 

 third straight, tip of ear shortly rounded off ; upper half of the outer 

 margin deeply concave, lower half convex, emarginate opposite the 

 base of the tragus, terminating beyond this and opposite base of 

 inner margin in a small convex lobe. Tragus moderately long and 

 subacute ; inner margin straight ; at the base of the outer margin a 

 rounded lobe, placed obliquely, from which the outer margin curves 

 slightly outwards and upwards, and attains its greatest convexity 

 slightly above the base of the inner margin, thence decreasingly 

 convex upwards, and straight in its upper third. 



Wings to the base of the toes ; a narrow but distinct postcal- 

 caneal lobule; calcaneum terminating in a small projecting tooth; 

 last rudimentary vertebra of tail free ; tail as long as the head and 

 body. 



The sides of the face are covered with a few long hairs, and the 

 mouth is margined by a dense fringe of fine straight hairs. The 

 fur of the body extends upon the wing-membrane on the upper 

 surface as far as a line drawn from the middle of the humerus to 

 the knee, upon the interfemoral membrane as far as the end of the 

 third caudal vertebra in the centre, and, laterally, as far as the end
