THE MAMMALS OF NEW JERSEY. 95 



This is a common species about the woods and open fields, 

 apparently not congregating about houses, as do the red and 

 large brown bats. 



Another closely related species, says bat Myotis suhulatiis, with 

 thinner membranes, longer ears and narrower skull, has the 

 same range, and doubtless occurs in New Jersey, being easily 

 confused with the present form. There is, however, no definite 

 record.

Genus Pipistrellus Kaup. 



Pipistrellus subfiavus (Cuvier). 



Georgia Bat. 



Plate 43- 



Length 3.40 inches. Spread of wings 8.50 inches. Wing 

 membranes thin, naked, except at base of the interfemoral mem- 

 brane. Fur light yellowish brown, blotched or mottled with 

 dusky, uniform yellowish brown below. 



This species is not uncommon, occurring in the same localities 

 as the little brown bat, with which it agrees in size, but it differs 

 in color and in the quality of its fur, which is looser and not so 

 silky.
