Promops bonariensis, Peters, MB. Akad. Berl, 1874, p. 232, pi. 

 Molossus bonariensis, Bobson, P. Z. S. 1876, p. 715. 



Ears united by a deeper band than in M. glaucinus ; ear-conch aa 

 broad as high ; antitragus broader than high, convex ; tragus quad- 

 rate, as in the preceding species ; muzzle obliquely truncated ; ex- 

 tremity of the nose almost double as broad as the base of the anti- 

 tragus ; upper Kp with a few shallow vertical wrinkles. 



"Wing-membrane from the ankles. 



Fur rather short, somewhat shorter above than beneath. Beneath, 

 the wing-membrane is covered as far as a line drawn from the 

 middle of the humerus to the knee ; a few short hairs extend along 

 the posterior margin of the forearm ; above, the outer half of the 

 antebrachial membrane is covered with short woolly hairs, and a 

 band of similar hairs passes outwards behind the forearm, becoming 

 gradually so broad as to cover almost half the metacarpal bone of 

 the last finger. Above, reddish brown, the base of the hairs whitish ; 

 paler beneath, the extremities of the hairs brownish white. 



The skull agrees in size with that of M. nasutus, Spix ; but the 

 facial portion is much longer and the brain-case wider than in 

 that species. Upper incisor on each side with a short outer basal 

 cusp, and separated from the canine by a slight interval ; first upper 

 small premolar in the space between the canine and second pre- 

 molar.

Ilab. Buenos Ayres. 



I have not seen the single specimen (as yet obtained) of this 

 recently described species. I have therefore been obliged to trans- 

 late Prof. Peters's original description, which is accompanied by an 

 excellent plate.
