Observations. This species of Bat is very widely distributed. 

 It was first noticed by Mr. Nuttall at Council Bluffs, on the Mis- 

 souri ; and Mr. Say describes an individual which was captured in 

 the same neighbourhood, in Long's Expedition. According to Dr. 

 Godman, it has been taken near Philadelphia. It has also been 

 found in Georgia by INIajor Le Conte, and near Charleston in 

 South Carolina by Dr. Backman. Still farther from the place 

 of its first discovery, it has been found near Salem, IMassachusetts. 

 From these facts, this fine species may be considered as common 

 throughout the United States, and especially on the Atlantic 

 coast. Dr. Richardson met with it also as far north as latitude 

 54^. Mr. William Cooper, whose opinion is always valuable, 

 supposes it may migrate to the South from this high latitude. It 

 is sometimes seen on the wing during the day especially in cloudy 

 weather.
