MAMMALIA. 



Order GHIROPTERA. Fam. VESPERTILIONIDjE. 



BARBASTELLE. 



Synotus barbastellus (Schreb.)- 



The only examples of this Bat that are known to have 

 occurred in Lakeland were captured many years ago in the 

 neighbourhood of Carlisle. They were skinned for the collec- 

 tion of Mr. T. C. Heysham. At the sale of his specimens they 

 were purchased by the late Mr. F. Bond, at whose house I had 

 the pleasure of examining them in March 1886. Their presence 

 in Cumberland can only be accounted for by the supposition that 

 they had migrated into Lakeland as summer visitants. There 

 can be no doubt that some species of Bats migrate seasonally. 

 In April 1891 I observed a small flight of large-sized Bats 

 migrating through one of the passes of the Pyrenees. These 

 animals were not hawking, but kept in a fairly compact body, 

 and flew with the same definite purposeness that one is accus- 

 tomed to remark in Swallows pressing forward on the return 

 journey to their breeding quarters. 



LONG-EARED BAT. 



Plecotus auritus (L.). 



This species is less evenly distributed than the Pipistrelle, 

 but in some places it is almost as numerous. The late James 

 Fell informed me that, while following his trade as a slater, he 

 had on several occasions found large colonies of this species in 

 the roofs of old buildings.
