anteriorly, and posteriorly sends backwards a vertical laterally 

 compressed process, which is either connected with the front 

 surface of the nose-leaf or free. Base of the outer side of the 

 ear expanded, forming a large antitragus. Wings very large;

The species, of which a figure is now given, Vesperugo noctula 

 (Plate III.), is doubtless the best known of the larger bats in 

 this country, and is very widely dispersed. Kegarding its
