LEISLER'S BAT 83 



peculiarities will be pointed out in the proper place. With 

 these exceptions it could be confused only with the much smaller 

 Leisler's Bat. Unlike some other species, the Noctule flies 

 with the tail directed straight backwards, or with only a very 

 slio-ht downward curve, a fact which may be supposed to have 

 some connection with the less frequent use of the interfemoral 

 pouch than in smaller and less powerful species.

 in the wooded districts of boreal and transitional Europe and Asia, from 

 sea-level to 4500 feet (Fatio) in the Alps, from middle Russia to Greece
