to the humid northwest-coast region and a lighter form occupying 

 the rest of the animal's range. That all of the lighter individuals 

 represent a single geographical race appears to be highly improbable, 

 but the material now at hand is not sufficient to form the basis for 

 any satisfactory subdividing. 



Hahits. — The long-eared bat occurs over a wide area chiefly west 

 of the Rocky Mountains in the United States, and apparently more 

 in the thinly forested country than in wooded sections. Judging 

 from specimens in collections, it is unusual to find them except as 

 scattered individuals. Gary (1911), however, obtained a series of 

 adult and immature examples, in August, 1906, from a deserted ranch 

 house near Sunny Peak, Routt County, Colo. At other places in the 

 same State, he secured additional specimens about ranch buildings 

 but failed to find them about ledges or cliffs. Where buildings are 

 not available this species probably finds shelter in crevices or per- 

 haps in trees. At all events it seems not to be reported from caves. 

 In Colorado, Young (1908) records it from an altitude of 7,000 feet.
