Of two specimens shot March 10, 1850, in Jordan River, one 

 was in full plumage. The other, a male, not quite mature, had 

 the space in front of the ejes and the flattened space at the base 

 of the bill above, covered with scattered, minute feathers. The 

 orange spot is indicated through the feathers. The bill is black 

 at the tip, base, and along the commissure, and of a dull yellow- 

 ish in the intermediate area. Feet mottled. The older one mea- 

 sured 51 inches in length and 76 in extent. Weight, 15^ pounds. 

 The young one, 47 by 71 ; weight, 9 J pounds. 



The range of this species is quite extensive. Inhabiting the 

 Atlantic in winter, especially Chesapeake Bay, it was found on 

 the Saskatchewan, in lat. 64°, by Sir John Richardson, and on 

 the Columbia River by Dr. Townsend, thus extending across the 

 continent.

This common bird occurs entirely across tne continent, being 



found abundantly in California, Oregon, the Atlantic States, and 



the intermediate country. In summer it goes northward to breed, 



extending almost to the shores of the Arctic seas. This goose 



constitutes the principal summer food of the inhabitants of the fui 



countries, large numbers being salted down for winter use. 



The specimens procured were shot on Salt Lake.
