Description. 



Ears short, roundish, naked on the anterior half ahove, and 

 furnished merely with a thin covering of fine hairs within. 

 Color of the fur above reddish tawney, in some individuals 

 deep, and more properly ferruginous ; in others very light- 

 colored : the base is of a light ochreous tint, towards the end 

 it is reddish tawney, ferruginous, or lake, and often finely tip- 

 ped with white, giving it a slightly hoary or cream-colored 

 appearance, according to the predominance of one or the other 

 of these tints. The reddish tawney always predominates on 

 the inlerfemoral membrane, which, and the feet, are densely 

 hairy down to the very edge. The wing membranes are en- 

 tirely naked above, with the exception of a small spot at the 

 base of the thumb, and about the base of the fore finger, which 

 in some individuals extends half an inch down each side of 

 the phalanx, though in others there is scarcely a trace. At 

 the insertion of the wings is a white mark, most conspicuous 

 on the under side. Beneath, the colors are similar to those 

 of the back, though paler ; a hairy border extends along the 

 anterior side of the membrane to the divergence of the phal- 

 anges. This part of the membrane is light yellow or tawney, 

 while the rest is dusky both in this and the preceding species.
