This species can scarcely be confounded with any other species, unless it may be with the 
New-York bat; from this, however, it is distinguishable by its greater size, and its distinct 
color. The bony processes supporting the interfemoral membrane are so stout and long, as 
to subtend that membrane, and alter its usual triangular form. 
The Carolina Bat is found along the Atlantic States, from Georgia to Connecticut. I have 
obtained it from Kings county, and Prof. Emmons has observed it at Albany, in the months 
of February and March. Its season of torpidity is probably of short duration.

* Under this head, we include short notices of species observed in the United States, or the adjacent regions, but which we 
have not seen in this State. The authority for the species must, of course, rest with their respective describers.
