This Bat, which is of a lighter colour than any 

 other of our indigenous species, is stated by Mr 

 enyns to occur in hollow trees at Swaffham in 

 Cambridgeshire, and to have been received by Mr 

 Yarrell from Colchester and Norwich. Mr Bel 

 had three individuals from Chiselhurst in Kent, 

 which were found in a chalk cavern at the bottom 

 of a shaft seventy feet deep, in company with Bar- 

 bastellus, Vespertilio mystacinus, and Plecotui 

 auritus.
