The fur of this bat differs from that of any other of the genus to which it belongs 

 in not being unicolored. That upon the back of the neck and shoulders pos- 

 sesses three well-defined hues the base is of a dark brown, the middle of a 

 paler hue, while the tip forms a delicate reddish brown. This, however, can 

 only be seen where the hair is thickest. Lower down upon the back and on 

 the belly the entire length of each individual hair is of one color. Everywhere 

 the hair covering is soft and yielding. All that space beginning between the 

 eyes and terminating at the middle of the back is of thick, fine, beautiful hair. 

 The sides are much thinner and darker ; they form a continuous line with 

 that of the ulna, where it extends down upon the wing membrane some little 

 distance. The continuation of the dorsal fur forms on the ventral surface of 

 the interfemoral membrane a sparsely furnished patch, which goes to make 

 the lower portion of the lateral fawn-colored bands. These latter are narrow 

 inferiorly, wider superiorly, where they terminate gradually in the lighter hue 

 of the cervical region. From the external side a prolongation is sent up along 

 the line of the humerus and ulna to within an inch of the carpal joint ; both
