NORTH AMERICAN FAUNA. 



9; breadth of rostrum at posterior border of large premolar, 5; man- 

 dible, 10.0; upper tooth row (exclusive of iucisors), 5.15; lower tooth 

 row, (>.8. 



Measurenmits. — See table, page 54. 



Specimens examined. — Total number, 9, 

 from the following localities: 



Alabama : Greeusboro, 1 (skin, Merriam coll.), 

 Kentucky: Bowling Green, 1. 

 Louisiana: Honma, 4 (skins). 

 Mississippi: Bay St. Louis, 1. 

 South Carolina: Hardeeville, 1 (skin, Miller 

 coll.). 



Virginia: Dismal Swamp, 1 (skin). 



General remarhs. — Tyi^ical Corynorhinus 

 macrotis, like the western subspecies, is dis- 

 tinguishable at a glance from all other Isforth 

 American bats by its generic characters. 

 xVmong the forms of Corynorhinus it may be 

 distinguished by its conspicuously bicolored 

 fur. The limits of this animaPs range are 

 not well understood, but it is probably a 

 characteristic species of the Austroriparian 

 fauna.
