fol'e, aj;r«'eably surpiiiscd one inoriiing to sec ;i boy outer my r(»(nii with u hat in Lis 

 hanil which, from its birge .size, I knew eoiild he no otlicr than the species which 

 I had so long desired to obtain. He said that he had found it hanging ni)on the 

 leaf of a tree and had killed it with a piece of limestone. This is, I think, the 

 first instance on record of a bat of this form being taken on the Atlantic slope. 

 This species, without doubt, inhabits the whole of Florida. They fly early in the 

 evening, often before sunset, and, as has lieen remarked, usually very high. 



Norie of the bats of Florida appear to hibernate, or at best they only remain quiet 

 during an occasionally cold night.*
