ORNITHOLOGY, 



6. Genus MARECA, Stephens, Gen. Zool. XII, p. 130 (1824). 

 1. Mareca AMERICANA [Gmelin). — The American Widgeon. 



Anas americana, Gm. Syst. Nat. I, p. 526 (1788). 



Wilson, Am. Orn. VIII, Plate LXIX, fig. 4 ; Aud. B. of Am. Plate 

 CCCXLV ; oct. ed. VI, Plate CCCLXXXIX. 



Mr. Peale states : 

 Was frequently seen on our route from the Columbia River to the 

 Bay of San Francisco, in California, wherever we found fresh-water 

 ponds." 



Strictly the same as the species of the Atlantic coast of the United 

 States. 



7. Genus QUERQUEDULA, Stephens, Gen. Zool. XII, p. 142 (1S24). 

 1. QuERQUEDULA cAROLiNENSis {Gmelin). — The Green-winged Teal. 

 Anas carolinensis, Gm. Syst. Nat. I, p. 533 (1788). 



Wilson, Am. Orn. VIII, Plate LXX, fig. 4 ; Aud. B. of Am. Plate 

 CCXXVIII ; oct. ed. VI, Plate CCCXCII. 



This species is stated by both Dr. Pickering and Mr. Peale to be 

 common in California and Oregon. 



The specimens in the collection of the Expedition apparently have 

 a nearer relationship to the Querquedula crecca, of the Old World, 

 than is generally to be found in the American bird. This character, 

 however, we have repeatedly noticed in specimens from Western 

 America, of birds like the present having very similar European re- 

 presentatives.
