200 Proposed Changes in the A. O. U. Check-List. ee 
Dafila acuta americana (Bonaparte) becomes Dafila acuta tzitzihoa 
(Vieillot) (Anas tzitzihoa Vieillot, Nouv. Dict. d’Hist. Nat., V, 1816, ; 
p. 163; Mexico), as the description of the latter evidently applies to 
the same bird. (Cf. Thayer and Bangs, Auk, XX XIII, 1916, p. 45.) 
Melanitta Boie. Recognized as a genus (cf. Miller, Auk, XX XIII, 1916, 
pp. 278-281) to include the following North American species now in 
the genus Oidemia: 
Melanitta fusca (Linnzus). 
Melanitta deglandi (Bonaparte). 
Melanitta perspicillata (Linnzus). 
Ardea herodias hyperoncha Stone, Auk, XX XIII, 1916, p. 426 (error), 
should be Ardea herodias hyperonca Oberholser. 
Tringa canutus (Linnzeus) becomes Canutus canutus rufus (Wilson) 
(Tringa rufa Wilson, Amer. Ornith., VII, 1813, p. 43; shores of the 
Middle States), since the American bird proves to be subspecifically 
separable from that of the Old World. (Cf. Mathews, Birds Aus- 
tralia, III, pt. 3, 1918, pp. 272-273.) 
Limnocinclus Gould, Handb. Birds Australia, II, 1865, p. 254 (type,. 
Totanus acuminatus Horsfield). Recognized as a genus to include 
Pisobia acuminata Horsfield (= Pisobia aurita of the A. O. U. Check- 
List). (Cf. Mathews, Birds Australia, III, pt. 3, 1913, pp. 259-262.) 
Pisobia aurita (Latham) becomes Limnocinclus acuminatus (Hors- 
field) (Totanus acuminatus Horsfield, Trans. Linn. Soc. Lond., XIII, 
May, 1821, p. 192; Java); since Tringa [= Pisobia] aurita Latham 
is the same as Actitis hypoleuca (Linneus). (Cf. Mathews, Birds 
Australia, III, pt. 3, 1918, pp. 258-259.) 
Pelidna alpina sakhalina (Vieillot) becomes Pelidna alpina pacifica 
Coues (Pelidna pacifica Coues, Proce. Acad. Nat. Sci. Phila., 1861, p. 
189), since the North American bird proves to be separable from that 
of eastern Asia. (Cf. Thayer and Bangs, Proc. New Engl. Zoél. Club, 
¥, 1914, ‘p:.17,) 
Arenaria interpres oahuensis (Bloxham). Tringa oahuensis Bloxham, 
Voyage Blonde, Sandwich Is., 1826, p. 251 (Sandwich Islands). 
Recognized as a subspecies for the birds from the Pacific Coast of 
North America now referred to Arenaria interpres interpres. (Cf. 
Mathews, Birds Australia, III, pt. I, 1913, pp. 5-10.) 
Lagopus lagopus lagopus (Linnzus) becomes Lagopus lagopus albus 
Gmelin (7'etrao albus, Gmelin, Syst. Nat., I, pt. Il, 1789, p. 750; 
Hudson Bay), since the Northwestern North American bird is sub- 
specifically separable from the European, which is Lagopus lagopus 
lagopus (Linnzeus). (Cf. Clark, Proc. U. S. Nat. Mus., XX XVIII, 
1910, pp. 52-53.) Range: Hudson Bay to Alaska. 
Lagopus rupestris kelloggz Grinnell. New subspecies. Grinnell, 
Univ. Calif. Publ. Zool., V, No. 12, March 5, 1910, p. 383 (Zaikof Bay, 
Montague Island, Prince William Sound, Alaska). 
Chloreenas Reichenbach, Nat. Syst. Vogel, 1852, p. XXV (type, Columba
