because, while Cerconectes possibly appeared before Erismatura, the 

 exact dates of publication are still too indefinitely determinable. 



Olor Wagler versus Cygnus Zimmermann. (Cf. Richmond, Proc. U. S. 

 Nat. Mus., LIII, Aug. 16, 1917, p. 587.) Change rejected, since 

 Zimmermann is here neither binomial nor an accepted binary author. 



Himantopus Brisson versus Hypsibates Nitzsch. (Cf. Mathews, Novit. 

 Zool., XVIII, No. 1, June 17, 1911, p. 7.) Change rejected, because 

 Brisson's names are held to be valid. 



Pisobia maculata (Vieillot) versus Pisobia pectoralis (Say). (Cf. 

 Mathews, Birds Australia, III, pt. 3, Aug. 18, 1913, p. 261.) Change 

 rejected, because Tringa maculata Vieillot is not preoccupied by 

 " Tringa maculata" Linnaeus, since there is no such combination in 

 the writings of Linnaeus. (Cf. Oberholser, 'The Auk,' XXXV, 

 No. 1, January, 1918, p. 63.) 



Tringa ocrophus Linnaeus versus Tringa ochropus Linnaeus. (Cf. 

 Hartert, British Birds, IX, No. 1, June 1, 1915, p. 9.) Change re- 

 jected, on the ground that Tringa ocrophus cannot be considered a 

 mere typographical error. 



Arenaria Brisson versus Morinella Meyer and Wolf. (Cf. Mathews, 

 Novit. Zool., XVII, No. 3, Dec. 15, 1910, p. 498.) Change rejected, 

 because Brisson's names are held to be valid. 



Chaemepelia Swainson versus Columbina Spix. (Cf. Allen, Science, 

 N. S., XXXIII, 1911, pp. 336-337.) Change rejected, because the 

 type of Columbina Spix was first designated (Gray, List Gen. Birds, 

 1841, p. 75) as Columbina strepitans Spix, which is generically dis- 

 tinct from the species of the genus currently called Chaemepelia. 

 (Cf. Todd, Annals Carnegie Mus., VIII, 1913, p. 515.) 



Falco aesalon Tunstall versus Falco regulus Pallas. (Cf. Hartert, 

 Hand-List British Birds, 1912, p. 112.) Change rejected, because 

 Falco aesalon Tunstall is not a nomen nudum, but a valid name, 

 based on the "Merlin" of Pennant's 'British Zoology' and "l'Emer- 

 illon" of Brisson's 'Ornithologie.' 



Aluco Fleming versus Flammea Fournel. (Cf. Mathews, Austral Avian 

 Record, I, No. 4, Sept. 18, 1912, p. 104). Change rejected, because 

 the earlier Tyto Billberg is not preoccupied by Tyta Billberg, and 

 is therefore the proper name for the Barn Owls. 



Cryptoglaux Richmond versus Aegolius Kaup. (Cf. Hartert, Hand- 

 List British Birds, 1912, p. 105.) Change rejected, on the ground 

 that Nyctala Brehm, from whatever date taken, is preoccupied by 

 Nyclalus Bowdich 1825; and that Aegolius Kaup 1829 is preoccupied 

 by Aegolia Billberg 1820. The only tenable name for the genus is 

 therefore Cryptoglaux Richmond. 



Cryptoglaux funerea richardsoni (Bonaparte) versus Cryptoglaux 

 tengmalmi richardsoni (Bonaparte). (Cf. Hartert, Hand-List 

 British Birds, 1912, p. 105). Change rejected, because Strix funerea 

 Linnaeus refers undoubtedly to this species, notwithstanding the 

 statement that it is of the size of a crow.
