The Faunce of the Eastern Province considered in Reference to the 

 Distribution of the Mammals and Reptiles. 



The faunae of the Eastern Province of the North American Region 

 above characterized from the distribution of the birds seem to be 

 equally well marked as natural zoological districts by the distribution 

 of the mammals and reptiles. About the same proportionate number 

 of mammals are limited similarly with the birds in regard to their 

 northward and southward distribution. The correspondence in the 

 geographical limitation of the species of the two groups will be 

 briefly shown by the following remarks respecting the range of the 

 mammals. 



The Arctic Realm is well known to be characterized by a few species 

 nearly or quite restricted to it, as the polar beat ( Ursus maritimus),
