Localities : Dublin, where it is by no means rare ; Kildai*e, Levits-

 probably distributed all over Ireland. The Dublin specimen (a female, 

 of which the measurements are given above) was captured clinging to a

 female, and not full grown.

 is very impatient, running up and down the sides of the net when cap- 

 tured, and squeaking and biting in impotent rage. It also was a great 

 adept at dodging the net ; not merely running up the sides of it, and es- 

 caping before I could bag it, but also turning in the net, and flying back 

 again before it reached the end. In the cage it was perpetually in mo- 

 tion, biting like a little fury, and squeaking and traversing it in every 

 direction. It fed freely enough. 



Bats generally presumed to be this species are veiy often seen hawk-

 remarkably mild one, nearly every day I saw one at noon, during Goto-
