stating the effects of these, the author proceeded to suggest, as the 

 result of his observation, that the facts known in relation to the sub- 

 ject, would authorize the belief that the country is divided (so far as 

 concerns these animals,) into several distinct zoological sections, 

 each more or less perfectly defined, and each inhabited by certain 

 species peculiar to itself. These he indicated as follows: — 



Sect. 1. — The peninsula of Florida. 



Sect. 2. — The Alluvial Region of the southern Atlantic coast and 

 of the Gulf of Mexico. 



Sect. 3. — The Southern Inland Section, comprising the territory 

 between the preceding and the river Ohio, and the State of Vir- 

 ginia. 



Sect. 4. — The Southern Inland Section, lying between the Ohio 

 River and the great Lakes, and embracing the middle Atlantic 

 States and a part of New England. 



Sect. 5. — The Northwestern Section, west and northwest of the 

 great Lakes. 



Sect. 6. — The Northeastern Section, between the river St. Law- 

 rence and the Atlantic Ocean. 



The physical features of each of these sections, were described, 

 and catalogues of the species inhabiting each were given, — and 

 the author concluded with some general remarks concerning the 

 introduction of foreign species.
