560 Description of a new English Bat. 



Dr. Leach, who with great liberality, forwarded a specimen to 

 one of the Conductors of our Journal, considers it as a new species, 

 and states in the Letter, dated October 12, 1824, accompanying 

 the specimen : 



" I have named it Vespertilio Pygmoeus', it was taken at 

 Spitchweek, near the forest of Dartmoor, where it is extremely 

 common. The specimen sent is a female, and had milk in its 

 mammx. All that I have seen are nearly of the same size."
