200 VESPERTILIONID.'E. 



V. megalurus has characters common to both Vesperugo and 

 Scoto_philus, resembling the species of the latter genus in the form 

 of the inner upper incisors, which are long and unicuspidate, and in 

 the position of the first lower premolar, also in the absence of a 

 postcalcaneal lobe. In aU other respects it agrees with the species 

 of Vespei-urjo (snbgen. Vesperus), to which genus it undoubtedly 

 belongs.

Head flat, muzzle conical, the extremity projecting considerably 

 beyond the lower lip in front, as in the species of the genus Nyeti- 

 notnus, terminated by the margins of the nostrils, which open sub- 

 laterally ; ears shorter than the head, triangular, with rounded-o£E 

 tips ; the inner margin of the conch commences above the eye, and 

 does not form a distinct rounded lobe at its base, but is straight 

 almost from the base to the tip of the ear, the outer margin is also 

 straight, and terminates rather abruptly midway beneath the iragus 

 and the angle of the mouth ; tragiis much longer than broad, 

 directed slightly inwards, reaching its greatest width below the 

 middle of its inner margin, outer margin coQvex, with an iU-defined 

 lobe near the base, inner margin slightly concave, tip subacutely 

 pointed. 



Tail almost whoUy contained in the interfemoral membrane, the 

 last rudimentary caudal vertebra alone free ; no postcalcaneal lobe ; 

 wings from the base of the toes. 



Fur short ; above, pale yellowish brown ; beneath, pale buff, 

 almost white ; membranes light brown, traversed by numerous 

 white reticulations. 



The face is nearly naked in front of the eyes ; a few hairs fringe 

 the lips and the under surface of the projecting extremity of the 

 muzzle ; the wing and interfemoral membranes are a,lmost naked. 



Upper inner incisors moderately long and unicuspidate, outer 

 incisors very short, but slightly exceeding the cingulum of the inner 

 incisors in vertical extent ; lower incisors trifid, crowded, placed 

 across the direction of the jaws ; the single upper premolar close to 

 the canine, as in V. serotinus, the first lower premolar not half the 

 second in vertical extent, with a prominent internal and anterior 

 basal cusp.
