PERUVIAN BAT. 
This Bnt is properly, the Vespertilio Lepori- 
nus, or Hare- Lipped Bat, of tlie Linn^aii sys- 
tem; as agreed, at present, by Dr. Gmelin, and 
all the principal naturalists: though Linnaeus 
himself, in his twelfth edition of the Systenia 
Nat'j.rGe, placed it in a distinct genus, called 
Noctilio. 
In Feuille's Observations on Peru, it is de- 
nominated the Bat from the Valley of Ylo; 
but Pennant, and other English nataralists, 
liave called it the Peruvian Bat. As the Hare- 
Lip does not appear to be absolutely confined 
to this species of the Bat, we have not adopt- 
ed the Linnsean appellation : an.], were t;c dis- 
posed lightly to disturb any of the more esia^ 
bliyhed names, in natural history, we should 
incline to call it the Ylo Bat. rather than even 
the Peruvian ; since there are, in Peru, other 
species of Bats. This latt reason onera'tes 
still more forcibly against calling it, after Sc- 
ba and otiiers, the American Bat. 
Pennant describes this reruvian Bat. es
