292 SWIMMERS. 



Hutchins Goose is how considered a variety of canadensis, 

 though in habits it is quite disfinct. 



The present race breeds in the Arctic region and winters in the 

 Southern States ; but on the Atlantic coast is now rather rare north 

 of Cape Hatteras, though formerly it was quite common. On the 

 prairies and west of the Rockies'^hese birds are still abundant. 



Note. — The Cackling Goose (.5. canadensis minima), a 

 smaller race, — length about 24 inches, — which breeds in Alaska 

 and winters in California, is occasionally represented in the Mis- 

 sissippi valley by a few individuals. 



Another occasional visitor from the West to this faunal province 

 is the Black Brant (B. nigricans'). A few examples of this 

 species have been taken on the Atlantic coast. 



Still another visitor of this group is the Barnacle Goose 

 {B. leucopsis), a European bird. ^This species is said to be a 

 regular visitor to South Greenland, and Reinhardt thought it 

 nested in the interior of that country. It has been seen also on 

 Hudson Bay.
