412 Thirteenth Supflemetit to the A. O. U. Check- List. Y^^ 



I. ADDITIONS TO THE CHECK-LIST AND ACCEPTED 

 CHANGES IN NOMENCLATURE.^ 



Genus ENICONETTA Gray. This becomes 

 Genus POLYSTICTA Eyton. 



Polysticta Eyton, Catal. Brit. Birds, 1836, 58. Type, Anas 

 sielleri Pallas. 



Enicotietta was proposed by Gray, to replace Polysticta Eyton, 

 on the ground that the latter name was preoccupied by Polysticte 

 Smith (1836). Eyton's Polysticta has, however, two or three 

 months' priority over Polysticte Smith {cf. Richmond, Proc. Biol. 

 Soc. Wash., XVI, 1903, 128). Steller's Duck thus becomes 



157, Polysticta stelleri (Pallas). 



243a. Pelidna alpina pacifica (Coues). An earlier name is 

 found in 



243a. Pelidna alpina sakhalina (Vieillot). 



Scolopax sakhalina Vieillot, Nouv. Diet. d'Hist. Nat., Ill, 

 1816, 359 {cf. BuTURLiN, Auk, 1904, 53). 



297c. Dendragapus obscurus sierras Chapman. 



Sierra Grouse. 



DefidragapHS obscurus sierrcB CiiAi^ux'i^, Bull. Am. Mus. N. H., 

 XX, April 25, 1904. 159. 



Geog. Dist. — California (forested portions of Transition and 

 Boreal zones), north to Fort Klamath. Oregon. 



Genus NYCTALA Brehm. This becomes 

 Genus CRYPTOGLAUX Richmond.
