Say's Bat, and the Carolina Bat have a strong external re- 

 semblance, and might be mistaken for each other, though there 

 is considerable difference in size, which, with the different form 

 of the tragus will enable the student to discriminate between 

 the two species. The dental systems, it will be observed, are 

 very unlike. That of V. subulalus is correctly described by 

 Dr. Richardson, as I have carefully verified. From the spe- 

 cimens and M.S. notes communicated to me by Major Le 

 Conte, I am satisfied of the identity of this with his V.lncifugiis, 

 to which he also assigns the same dentary system. 



This species, first made known by Mr. Say, in the notes 

 to the account of Long's first expedition, was afterwards more 

 minutely described by Dr. Richardson, who found it the most 

 common Bpeciea of J iat near the eastern base of the Rocky 

 Mountains! and Mr. Townsend has recently brought it from 

 Columbia river. A specimen obtained by Dr. Pickering 

 in the mountains <>l .Wu Hampshire, is preserved in the 

 cabinet of the Academy of Natural Sciences, and 1 have seen 

 another procured by Mr. Audubon, in Labrador. I have a 

 specimen from Pittsburg, on the Ohio. In our vicinity, and 

 in the city itself, it is pretty common. Major Le Conte, 

 and Mi- Bachman, have communicated specimens from Geor- 

 gia and Carolina. It is therefore, though one of the latest 

 known, at tin- same time one of the most widely diffused over 

 the I nited Slat. .
