Vol. io | Supplement to the A. O. U. Check-List. 449 
Avian Record, III, No. 3, 1917, p. 119%) Change rejected, because 
the authors of Regulus Bartram 1791 and Regulus Zimmermann 1793, 
which supposedly preoccupy Regulus Cuvier are neither binomial nor 
acceptedly binary. 
Sialia Swainson versus Rubecula Zimmermann. (Cf. Mathews, ‘The 
Auk,’ XXXI, No. 1, Jan., 1914, pp. 89-90.) Change rejected, be- 
cause Zimmermann is not binomial in the publication in question 
(Bartram, Reisen Nord- und Stid-Karolina, 1793, p. 287), nor is 
he a binary author accepted by the International Zoological Com- 
mission. Furthermore, Rubecula is not actually adopted as a generic 
name by Zimmermann, but simply cited as a polynomial synonym. 
The list of “Nomina Conservanda”’ proposed by the Committee of the 
British Ornithologists’ Union (List Brit. Birds, ed. 2, 1915, p. 355) 
contains the following five names that affect the present status of the 
A. O. U. Check-List: 
Turdus musicus Linnacus versus Turdus iliacus Linnaeus. 
Asio flammeus (Pontoppidan) versus Asio accipitrinus (Pallas). 
Cryptoglaux Richmond versus Nyctala Brehm. 
Anas platyrhyncha Linnaeus versus Anas boschas Linnaeus. 
Pterodroma Bonaparte versus Oestrelata Bonaparte. 
These changes are not acceptable under the law of priority.
