XS a species less common in Great Britain 

 than the smaller. It ranges high in the air for 

 food, and retires early in the summer. Is the 

 largest we have ; its extent of wing is fifteen 

 inches ; its length to the rump two inches eight 

 tenths ; that of the tail one inch seven tenths. - 

 The nose is slightly bilobated ; the ears small and 

 rounded ; on the chin is a minute wrruca. Hair 

 on the body a reddish ash-color. 



They collect under eaves of buildings in vast 

 numbers. The Rev. Doctor Buckzvorth in- 

 formed me that under those of Queen s College, 

 Cambridge, he saw taken, in one night, one hun- 

 dred and eighty-five; the second night sixty- 

 three ; the third, two.
