* ****** 



The forms of Antrozous are well characterized by their 

 large size, big ears, pale color, and ridge above the nostrils, 

 and are not likely to be confused with any other Bat in the 

 United States. 



These Bats live in the roofs of buildings or other darkened 

 nooks in bams, churches, etc., and in crevices in cliffs. They 

 are common in many places and because of their habit of tak- 

 ing up quarters in human habitations may become a nuisance. 

 The flight is not as erratic as that of most Bats, although 

 rapid. 



There is evidence to show that these Bats catch some of 

 their prey, such as Jerusalem Crickets, upon the ground, also 

 that they are to some extent, at least, migratory. 



The number of young at birth varies from one to three. 



Family Molossidfie 



This family shares with the Vespertilionidce a very high 

 degree of flight specialization. The members of this family 

 may be recognized by the blunt, obliquely truncate muzzle 

 which is generally set with short, specially modified hairs 

 having "spoon-shaped" tips; nostrils terminating in a modified 

 pad which may be fringed with dermal excrescences; ears 

 variable in size and shape, sometimes joined across forehead;
