392 CHECK-LIST OF NORTH AMERICAN BIRDS. 



CoDipsuthlijpis amcricana usncac Brewster, 1896, becomes C, a. pusilla 

 (Wilson), 1811. 

 Wilson's name being based on the northern lace has priority over that 

 of Brewster. (Cf. Brewster, Auk, XXXV, 1918, 228.) (p. 284) 



Dendroica hryanti castaneiceps Ridgway, 1885, becomes D. erithachoridcs 

 castaneiceps. 

 The former species hryanti and erithachoridcs are now regarded as only 

 subspecifically different and all races of the two thus become subspecies 

 of the earlier erithachorides. (Cf. Oberholser, Auk, XXXVI, 1919, 85.) 

 (p. 286) 



Dendroica vigorsi (Atjdubon), 1828, becomes D. pinus pinus (Wilson), 1811. 

 Wilson's name (proposed in the genus Sylvia) was rejected as it was sup- 

 posed to be invalidated by the earlier Sylvia pitius Latham, but the latter 

 proves to be merely a nomenclatural combination and not an original 

 description and consequently does not affect Wilson's name which has 

 now been restored (Stone, Auk, XXXVIII, 1921, 280). The specific 

 name has been repeated to distinguish this race from others recently 

 described, (p. 291) 



Agelaius phoeniceus jloridanus Maynard, 1895, becomes^, p. mearnsi Howell 

 AND van Rossem, 1928. 



Agelaius phoeniceus hryanti Ridgway, 1887, becomes A. p. jloridanus. 



Maynard's name was originally based on the bird of the Florida Keys to 

 which it is now restored, replacing hryanti which is restricted to the 

 Bahaman race; while for the bird of the Florida peninsula the name 

 mearnsi the first to be proposed is adopted. (Howell and van Rossem, 

 Auk, XVL, 1928, 155.) (p. 303) 



Agelaius phoeniceus richmondi Nelson, 1897, becomes A. p. megapotamus 

 Oberholser, 1919. 

 The former name has been restricted to the bird of the Vera Cruz region 

 and the form reaching the United States is separated as megapotamus. 

 (Cf. Oberholser, Wilson Bull, XXXI, 1919, 20.) (p. 304) 



Agelaius gubernator californicus Nelson, 1897, becomes .4. phoeniceus cali- 

 Jornicus. 

 The former species guhernator and phoeniceus are now regarded as differing 

 only subspecifically and all races of the former become subspecies of the 

 latter, (p. 305) 



Megaquiscalus major major (Vieillot), 1819, becomes Cassidix mexicanus major. 



Megaquiscalus major macrourus (Swainson), 1838, becomes Cassidix mexicanus 

 mexicanus (Gmelin), 1789. 

 It develops that Corvus mexicanus Gmelin is based on the Great-tailed 

 Grackle so that the name mexicanus, long antedating major, becomes the 

 specific name for both the Great-tailed and Boat-tailed Crackles and, of 

 course, also the subspecific name of the former. Furthermore the generic 

 name Cassidix being based on Corvus mexicanus becomes the proper 

 generic name for these birds, replacing Megaquiscalus proposed many years 

 later. (Cf. Peters, Proc. Biol. Soc. Wash., XLII, 1929, 121.) (p. 308)
