412 Thirteenth Supplement to the A. O. U. Check-List. aie 
I. ADDITIONS TO THE CHECK-LIST’ AND ACCEPTED 
CHANGES IN NOMENCLATURE. 
GENUS ENICONETTA Gray. This becomes 
Genus POLYSTICTA Evron. 
Polysticta Eyton, Catal. Brit. Birds, 1836, 58. Type, Anas 
x 
SteVleri PALLAS. 
Eniconetta was proposed by Gray, to replace /v/ysticfa Eyton, 
on the ground that the latter name was preoccupied by /o/ysticte 
SMITH (1836). Eyton’s /o/ysticfa has, however, two or three 
months’ priority over /o/ysticte SMITH (cf RicHMOND, Proc. Biol. 
Soc. Wash., XVI, 1903, 128). Steller’s Duck thus becomes 
157. Polysticta stelleri (PALwas). 
243a. Pelidna alpina pacifica (Covers). An earlier name is 
found in 
243. Pelidna alpina sakhalina (VieiLLor). 
Scolopax sakhalina VietLLot, Nouv. Dict. d’Hist. Nat., III, 
1816, 359 (of BuTuRLIN, Auk, 1904, 53). 
297c. Dendragapus obscurus sierrze CHAPMAN. 
Sierra Grouse. 
Dendragapus obscurus sterr@ CHAPMAN, Bull. Am. Mus. N. H., 
XX, April 25, 1904, 159. 
Groc. Dist. — California (forested portions of Transition and 
Boreal zones), north to Fort Klamath, Oregon. 
Genus NYCTALA Breum. This becomes 
Genus CRYPTOGLAUX RicHmonp.
