382 CHECK-LIST OF NORTH AMERICAN BIRDS. 



Harelda Stephens, 1824, becomes Clangula Leaoh, 1819. 



The earlier Clangula Oken being a nomen nudum restores Leach's name 

 to consideration, which has priority over Harelda Stephens. (Cf. B. O. 

 U. Comm., List Brit. Birds, 1915, 384.) (p. 54) 



Oidemia has been divided and 0. fusca, deglandi,, and perspicillala are referred 

 to Melamtta. (p. 57) 



Cathai'isla Vieillot, 1816, becomes Coragyps Le Maout, 1853. 



The type of the former is found to be Vidtur aura Linnaeus, making it a 

 synonym of Cathartcs; Cnragyps is adojited as the earhest available 

 name for the present genus. (Cf. Stone, Princeton Patag. Exped., II, 

 1915, 540.) (p. 61) 



Catharisla urubii (Vieillot), 1807, becomes Coragyps atraius alraius (Meyer) 

 1794. 

 Meyer's name based on Bartram is held to be valid and antedates tirubu. 

 (p. 61) 



Buteo abhreviatus Cabanis, 1848, l:)ecomes Buieo albnuolalns Kaup, 1847. 



On grounds of priority. (Cf. Swann, Synops. Accipitres, Pt. 2, 1922, 83.) 

 (p. 68) 



Buleo albicaudatus scnnctli Allen, 1893, becomes Buteo a. Iiypospodius Gurney, 

 1876. 

 On grounds of priority, (p. 68) 



Archibuteo has been combined with Buteo. (p. 69) 



Archihutco ferrugincus (Lichtenstein), 1839, becomes Buteo regalis (Gray), 

 1844. 

 The former name originally proposed as Falco Jerrugitwus is invalidated by 

 the earlier Falco f err ugineus Nordmann, 1835, and is replaced by the ear- 

 liest available name regalis. (Stresemann, Ornith. Monats., XXX, No. 4, 

 1922, 87.) (p. 69) 



Falco islandus Brunnich, 1764, becomes Falco rusticolus candicans Gmelin, 

 1788. 

 It is considered that the former name does not apply to any North 

 American Gyrfalcon and the latter is accepted as the first one available 

 for our bird which is now regarded as a subspecies of the European F. 

 rusticolus. (Hartert, Novitates ZocL, XXII, 167.) (p. 73) 



Ortalis vetula mccalli Baird, 1858, becomes 0?'/oKs vetula vetula (Wagler), 1830. 

 It is now considered that Wagler's bird belonged to the northern race 

 which enters the United States and not the one occurring in southern 

 Mexico, consequently his name replaces mccalli over which it has priority. 

 (Cf. Miller and Griscom, Auk, XXXVIII, 1921, 44.) (p. 78)
