Muzzle narrow, elongated ; nostrils very prominent, consisting 

 of two diverging tubes with an emargination between, opening 

 laterally ; viewed from below, the projecting nostrils resemble in 

 shape a small hour-glass placed horizontally at the extremity of the 

 muzzle. Ears moderate, shorter than the head, rounded off at the 

 tips ; the upper third of the outer margin angularly emarginate as 

 in Vespertilio emarginatus, the middle third commencing by a very 

 abrupt convexity, then slightly concave opposite the middle of the 

 tragus, and terminating in a convex lobe slightly in front of the 

 base of the tragus. Tragus moderately long, attenuated above and 

 slightly curved outwards ; a small pointed lobule at the base of the 

 outer margin, succeeded by a slight emargination, immediately above 

 which the tragus attains its greatest width; inner margin slightly 

 convex from the base upwards ; outer margin straight below, upper 

 half concave, causing the extremity to incline outwards ; tip sub- 

 acutely pointed. 



Wings from the sides of the outer toes, extending almost as far 

 as the claws ; extreme tip of the tail projecting ; calcanea distinct, 

 extending halfway between the ankle-joint and the extremity of 

 the tail, ending abruptly. 



The long fur ends in front between the ej-es ; but the face is 

 clothed with short fur, which leaves the tubular nostrils alone 

 naked. The wing-membranes on the upper surface are covered as 

 far as a line drawn from the middle of the humerus to the knee- 

 joint ; the interfemoral membrane is naked, except at the base 

 between the thighs. Beneath, the membranes are even less covered 

 than on the upper surface. Pur moderately long ; above light 

 greyish brown, the extremities dark brown ; beneath light greyish 

 brown throughout. 



The upper incisors on each side are nearly equal in size, stout, 

 and obtusely pointed, lying close together by their whole length, 

 the base of the outer incisor close to the canine ; the outer incisor 

 is, if any thing, longer, with a distinct cingulum, from which a small 

 blunt cusp projects outwards and touches the canine. The first 

 premolar is small, scarcely one third the bulk of the second pre- 

 molar, which very nearly equals the canine in vertical extent, and 

 exceeds it considerably in cross section ; the last molar is a simple 

 transverse plate. In the lower jaw the incisors are trifid and 

 slightly crowded, those next the canines longest ; the canines are 

 very short ; the first and second premolars are shorter than the 

 canine, and the first premolar is slightly less than the second in 

 vertical extent.
