Aegialitis Boie becomes Charadrius Linnaeus, because the type of 

 Charadrius Linnaeus is, by tautonymy, Charadrius hiaticula Lin- 

 naeus. (Cf. Mathews, Novit, Zool., XVIII, No. 1, June 17, 1911, 

 pp. 5-6.) The North American species are: 



274. Charadrius semipalmatus Bonaparte. 



275. Charadrius hiaticula Linnaeus. 



276. Charadrius dubius Scopoli. 



277. Charadrius melodus Orel. 

 27S. Charadrius nivosus (Cassin). 

 279. Charadrius mongolus Pallas. 



Chaemepelia passerina terrestris (Chapman) becomes Chaemepelia 

 passerina passerina (Linnaeus) (Columba passerina Linnaeus, Syst. 

 Nat., ed. 10, I, 1758, p. 165; "America inter tropicos"), because 

 Bonaparte in 1855 was the first author to fix the type locality of 

 Columba passerina Linnaeus, and he restricted it to North America. 

 (Cf. Todd, Annals Carnegie Mus., VIII, 1913, p. 533.) 



Catharista Vieillot becomes Coragyps Geoffroy (Le Maout, Hist. Nat. 

 Oiseaux, 1853, p. 66; type, Vultur urubu Vieillot), because the type 

 of the former proves to be Vultur aura Linnaeus, and Coragyps Geof- 

 froy is therefore the earliest tenable generic name for the Black Vul- 

 ture. (Cf. Stone, Princeton Patag. Exped., II, pt. IV, 1915, p. 540; 

 Chubb, Birds Brit. Guiana, I, 1916, p. 208.) The only North Amer- 

 ican form is 



326. Coragyps urubu urubu (Vieillot). 



Aluco Fleming becomes Tyto Billberg (Synop. Faunae Scand., I, pars 2, 

 1828, tab. A; new name for Strix Savigny; type, Strix alba Scopoli), 

 because Aluco Fleming 1822 is preoccupied by Aluco Link 1807; and 

 because Tyto Billberg, not being invalidated by Tyta Billberg 1820, 

 a word of different classical termination, is the earliest available name. 

 (Cf. Mathews, Novit. Zool., XVII, No. 3, Dec. 15, 1910, p. 500.) 



Oreospiza Ridgway becomes Oberholseria Richmond (Proc. Biol. Soc. 

 Wash., XXVIII, Nov. 29, 1915, p. 180; type by original designation, 

 Fringilla chlorura Audubon), because Oreospiza Ridgway 1896 is 

 preoccupied by Oreospiza Keitel 1857, and Oberholseria is proposed 

 in its place. (Cf. Richmond, loc. cit.) The only species is 

 592. 1. Oberholseria chlorura (Audubon). 



Mniotiltidae becomes Compsothlypidae, because Compsothlypis 

 Cabanis, not Mniotilta Vieillot, is the type genus of the family. (Cf. 

 Oberholser, Proc. Biol. Soc. Wash., XXXII, April 11, 1919, p. 46.) 



Helinaia Audubon becomes Limnothlypis Stone (Science, N. S., XL, 

 No. 1018, July 3, 1914, p. 26; type by original designation and mono- 

 typy, Sylvia swainsonii Audubon), because the type of Helinaia 

 Audubon is, by subsequent designation (Gray, List Gen. Birds, ed. 

 2, 1841, p. 33), Motacilla vermivora Gmelin, which makes Helinaia a 

 synonym of Helmitheros Rafinesque. (Cf. Stone, loc. cit.; and Rich-
