 branes naked, except the base of the interfemoral membrane. Fur

Probably the commonest species of bat in the State, frequently 

 entering houses and probably the species so frequent about the 

 electric lights, although the identification of bats on the wing- 

 is not an easy matter, nor is it much easier to secure them by 

 means of a gun, for their erratic flight and the gathering gloom 

 make them anything but easy targets.
