Description. — False molars |?-. In shape and size very- 

 similar to V. mystacinus, for which it may easily be mis- 

 taken ; distinguished from it, however, by the deep notch 

 on the outer edge of the ear, and by the entire absence of 

 the moustache on the upper lip, as well as by the generally 

 reddish tint of the fur. Ears oblong, as long as the head, 

 bending outward, with a small fold on the inner margin, 

 and a deep notch, with a small lobe beneath it, on the outer 

 margin; tragus subulate, bending outwards, rather more 

 than half as long as the auricle ; tail not longer than the 

 body, base of the ears very hairy. Fur on the head and 

 upper parts of the body reddish brown, shaded with yel- 

 lowish and brown tints, arising from the hairs being brown 

 at the base, yellowish in the centre, and with reddish-brown 

 tips ; all the lower parts ashy, with a slightly reddish tinge, 

 which tinge prevails over the upper part of the humerus ; 

 ears and membrane dull brown. 



Length of head and body from 2 inches to 2 inches 1 line ; 

 tail, 1 inch 3 lines ; humerus, 11 lines ; fore-arm, 1 inch 

 5 bines ; extent of wings from 9 inches to 9 inches 5 lines.
