^'"'igos'^] Fourteenth Supplement to the A. O. U. Check-List. 361 



133. Anas obscura Gmelin. This is changed to 

 133. Anas rubripes (Brewster). 



Anas obscura rubripes Brewster, Auk, XIX, 1902, lS-1. 



The name Anas obscura Gmelix, 1788, proves to be preoccupied 

 by Anas obscura Pontoppidan, 1763, for an Old World species, 

 and no other name being available, rubripes of Brewster is adopted 

 as a substitute. (Richmond, MS.) There is some question as to 

 the validity of the form recognized as No. 133a, which, by the 

 above action, is now cancelled. (See Eliminations.) 



Genus QUERQUEDULA Stephens. Authority is changed to 



Genus QUERQUEDULA Oken. 



Querquedula Oken, Isis, I, 1817, 1183, Tyjae, Anas circia 

 LiNN.EUS = A. querquedula LiNN.EUs. 



[141.1.] Casarca casarca (Linn.eus). This becomes 



[141.1.] Casarca ferruginea (Pallas). 



Anas ferruginea Pallas, in Yroeg's Cat., 1764, Adumbr., 5.. 

 {Cf. Richmond, Smiths. Misc. Coll., Quarterly Issue, XLVII^ 

 1905, 346.) 



Genus AYTHYA Boie. This becomes 



Genus MARILA Oken. 



Marila Oken, Isis, I, 1817, 1183. Type, Anas marila LiN- 

 N.Eus. (C/. Stone, Auk, XXIV, 1907, 191; also Allen,. 

 Bull. Am. Mus. N. H., XXIV, 1908, 26.) 



Aythya Boie, 1822, is preoccupied by Aethia (or Aethya) Du- 

 MONT, 1816; rnoreover, its priority over Nyroca Fleming, 1822,. 

 has never been satisfactorily demonstrated.
