The Rev. L. Jenyns on the Common Bat of Pennant. 163 



however, makes this species larger ; and the dimensions which 

 he has assigned for the length of the head and tail and for the 

 expanse of wing are scarcely at all different from the results at 

 which I have arrived. I may add also, that in the British Mu- 

 seum there is a specimen of the Pipistrelle *, sent by Dr. Leach 

 from the north coast of Scotland, which is even larger than that 

 described by Geoffroy ; and with which I have compared more 

 than once not only my own specimens of the Common Bat, but 

 likewise those so named in the above Museum, after Pennant, 

 without being able to detect any thing like a specific dif- 

 ference. 



Rather, however, than dwell any further upon the identity of 

 these species, or stop to point out every mark of similarity 

 between them, I beg to subjoin a more accurate description of 

 our Common Bat than is to be met with in any of our English 

 authors ; after which persons will be the better enabled to form 

 their own opinions on this subject.

* Mr. Gray of the British Museum, informed me that he believed this specimen 

 was named by Kuhl, which, if so, is strong testimony in favour of its being the same 

 with the Pipistrelle on the continent, notwithstanding its superior size.
