IV. 



A small collection of bats made by Dr. E. Coues, U.S.A., in 1864 and 1865, 

 was found to be comprised as follows : 



7802. V. subulatus, Fort Whipple. Smithsonian Institution. Dry. 



7803 " " " " " " 



The only peculiarity in these specimens is a more extensive distribution of 

 the fur over the dorsal surface of the interfemoral membrane than is seen in 

 the more eastern specimens. 



The fourth specimen was an imperfect skin. The proportions of the face 

 distorted, the wings broken, and the vertebra of the tail removed. Enough 

 remained, however, to detect marked differences between it and the others, 

 warranting, it is thought, a distinctive name. 



V. macropus, n. s. prov. 



Above, fur long, silky, basal three-fourths black, apical fourth uniform light 

 russet brown ; a small clump at base of inter-femoral membrane. Beneath, 

 same proportions as above, being at base black, at tip greyish-white, pure 

 white at pubis ; fur extends laterally on membrane midway to elbow. Wing 

 membrane attached midway between base of outer toe and ancle joint. In other re- 

 spects it closely resembles V. subulatus.
