 represents the adult of the size of life.

 yellowish brown.

Anas viduata, Linn. Syst. Nat. i. p. 205. 

 Numerous specimens from the Camma and Ogobai. 



229. Querquedula Hartlaubii, nobis. 



Querquedula cyanoptera, Hartl. 



" Anas cyanoptera, Temm. Mus. Lugd." 



The name by which this handsome species is given in Dr. Hartlaub's Orni- 

 thology of Western Africa, adopted from that of Temminck in the Leyden 

 Museum, was long since anticipated by Vieillot in Nouv. Diet. v. p. 104. The 

 species too, described by Vieillot as Anas cyanoptera, is a Querquedula, and the 

 same as described and figured by me in Birds of Caiifornia and Texas i. p. 82, 

 pi. 15, and now well known as a bird of the Western regions of North America. 

 I take the liberty, therefore, of applying to this bird the name of its first dis- 

 criber, in which I hope to be sustained by naturalists, not only for reason? 

 above mentioned, but as an act of justice to one who has contributed in the 

 most important manner to Western African Ornithology. 



This handsome bird is evidently an abundant species on the Camma and 

 Ogobai. The sexes are very nearly alike.
