ROSS ON MA.MMALS, ETC. OP THE MACKENZIE EIVEE DISTEICT. 287 



No. of Species. 



fl4<5. Beniicla I£utchinsii\\ (Bon.). Hutchin's Goose. North to 

 Arctic coast : common. 



146. Bernicla Barnstenii?\\ (Ross). This bird was shot at Fort 



Simpson. It is of very large size, with the breast of a 

 bright fawn colour. The delta of feathers running up into 

 the lower mandible is white, instead of black, as in 

 B. Canadensis. The tail is of 16 feathers. The Indians 

 consider it a species distinct from the Canada Groose. It 

 seldom flies in parties of more than five or six. I cannot, 

 however, positively state it to be a new species until the 

 Berniclce of North America are properly worked up, as 

 they are in rather a hazy condition at present. 



147. Bernicla hrenta (Steph.). Brant. North to Toucon River. 



From information. This may probably be the B. nigricans 

 (Cassin), as the Youcon has, in all likeliliood, a Pacific 

 Fauna.
