 Peruvian Bat. Pennant Quadr. 



Linnaeus, as Mr. Pennant well observes, car- 

 ried away by the love of system, placed this spe- 

 cies, in the twelfth edition of the Systema Na- 

 turae, under a distinct genus, by the name of 

 Noctilio; stationing it at a great distance from 

 the rest of the Bats, in the order Giires, next 

 to the Squirrels. This he did merely on account 

 of its having only two cutting-teeth in each jaw. 

 But succeeding observations have conspired to 

 prove that the number and disposition of the teeth 

 differs greatly in the different species of the Bats; 

 so that if a too rigid regard were paid to this par- 

 ticular, several distinct genera might be instituted 

 instead of one; but the general characters of the 

 Bats are so striking as to render this perfectly un- 

 necessary.
