 the upper jaw. 



Button appears to be the first naturalist who recorded this spe- 

 cies, and his account of it has been copied by succeeding writers. 



It seems to partake of the habits of the common Bat ; but it 

 may be readily distinguished from Vespertilh murimis, even on 

 wing, in the earlier part of the evening, by its superior size, and 

 in being by far the darkest in colour of all the British Bats. 

 Upon comparison, the flattened nose, more pointed ears, and 

 particularly the base of these coming so forward on the fore- 

 head as scarcely to leave any space between, will be found es^ 

 sential characters of distinction. 



I have not been able to discover the hybcrnaculum of this 

 species, but it is reasonable to believe its torpid state is passed 

 in? similar situations to those in which all but the V. Ferritin- 

 equinum and V. minutus retire during the colder months; none of 

 which appear to be subterraneous.
