On the dorsal surface the fur extends upon the wing-membrane 

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

 and the base of the interfemoral is occupied by a triangular patch 

 of moderately long hairs. Beneath, the hair extends more densely 

 somewhat beyond a line drawn from the elbow to the knee-joint, 

 a few hairs passing outwards behind the elbow and posterior to the 

 forearm and carpus, ranged along part of the oblique parallel lines 

 traversing the wing-membrane from the forearm backwards, as in 

 Vesperugo noctula. The fur covering the head, neck, and shoulders 

 is black, with a very faint reddish tinge ; posterior to the point 

 of origin of the antebrachial membrane the fur is dark at the base, 

 the terminal half of the hairs yellowish brown, at the base of the 

 tail and upon the interfemoral membrane yellowish brown through- 

 out. Beneath, on the breast, the bases of the hairs dark, the 

 terminal half reddish or ashy, on the abdomen the extremities of 

 the hairs yellowish white, while on the sides of the body and on 

 the wing- and interfemoral membranes the fur is pale yeUowish- 

 white throughout. 



Inner incisors unicuspidate and long ; outer incisors very short, 

 close to the outer and anterior sides of the bases of the inner inci- 

 sors (Plate XIV. fig. 46). Lower incisors trifid, crowded. First upper 

 premolar exceedingly small, so minute as to be seen only with the aid 

 of a lens, wedged in between the inner parts of the contiguous edges 

 of the bases of the canine and second premolar, as in V. noctula ; 

 the second premolar" is closely approximated externally to the canine, 

 and the minute first premolar cannot be seen from without. The 

 first lower premolar equals half the second in vertical extent.
