1863]. MR. R. F. TOMES ON A NEW BAT. 83 



LONCHORHINA AURITA, 11. S. 



Nearly the whole of the face is hairy, the hair having the same 

 quality and colour as that of the back ; the nose-leaf and fleshy ex- 

 crescences are naked, but a few hairs spring from the edges of the 

 former near the base ; ears hairy behind for three-fourths of their 

 length ; inside they have a distinct band of hairs on the inner mar- 

 gin, which does not extend further than three-fourths of their length 

 from the base ; and there is another, but smaller, band of hairs in- 

 side the lobular parts. 



The fur of the upper parts is nearly confined to the body, but 

 there is a little scattered on the humerus and the contiguous end of 

 the forearm. Beneath, there is a little whitish hair powdered on 

 the membrane near the flanks and forearms. 



All the upper parts are light reddish brown, the fur nearly uui- 

 color ; beneath similar, but duller in colour and paler on the pubes. 

 Cutaneous system dark reddish brown.

Hab. The bottle from which this specimen was taken contained 

 several West Indian species, in which the Mormops blainvillii and 

 the Chilonycteris gymnonota of Wagner were conspicuous. The 

 latter is distinguished from other species of the genus by having the 

 wing-membranes springing from the middle of the back, instead of the 

 sides of the body ; and there can be but little doubt that it is the 

 Pteronotus davyi of Dr. Gray. Of course Dr. Gray's specific name 

 will take precedence of that given much later by M. Wagner, and 

 the name of Pteronotus may be conveniently used to distinguish the 

 species as a subgenus of Chilonycteris. It is probable that the spe- 

 cimen from which I have taken the foregoing description may have 

 been received from the same locality as the Mormojjs and Pteronotus.
