448 Supplement to the A. 0. U. Check-List. [£jjj 



Dryobates Boie versus Dendrocopos Koch. (Cf. Hesse, Ornith. Mo- 

 natsb., 1911, pp. 160-162.) Change rejected, because Dendrocopos 

 Koch, July, 1816, is preoccupied by Dendrocopus Vieillot, April, 1816, 

 and therefore the proper name for the present genus is Dryobates 

 Boie. 



Loxia Linnaeus versus Crucirostra Scopoli. (Cf. Mathews, Novit. 

 Zool., XVII, No. 3, Dec. 15, 1910, pp. 501-502.) Change rejected, 

 because the removal of Loxia curvirostra from Loxia as the monotypic 

 type of Crucirostra Scopoli does not prevent the same species from 

 later being designated as the type of Loxia. Furthermore, Loxia 

 curvirostra is by tautonymy the type of Loxia Linnaeus. 



Passerina Vieillot versus Linaria Bartram 1791 and Zimmermann 1793. 

 (Cf. Mathews, 'The Auk,' XXXI, No. 1, Jan., 1914, pp. 88-90; 

 Richmond, Proc. U. S. Nat. Mus., LIII, Aug. 16, 1917, p. 599.) 

 Change rejected, because neither Bartram nor Zimmermann are 

 either binomial or binary authors accepted by the International 

 Zoological Commission. 



Piranga Vieillot versus Merula Zimmermann. (Cf. Mathews, 'The 

 Auk,' XXXI, No. 1, Jan., 1914, pp. 88, 90; Richmond, Proc. U. S. 

 Nat. Mus., LIII, Aug. 16, 1917, p. 603.) Change rejected, on the 

 ground that Zimmermann is here neither binomial nor a binary 

 author accepted by the International Zoological Commission. 



Hirundo Linnaeus versus Chelidon Forster. (Cf. Mathews, Novit. 

 Zool., XVII, No. 3, Dec. 15, 1910, p. 501.) Change rejected, because 

 Forster did not actually fix the type of Hirundo Linnaeus when pro- 

 posing (Syn. Cat. Brit. Birds, 1817, p. 17) for Hirundo rusiica Lin- 

 naeus the generic name Chelidon; wherefore Selby (Illustr. Brit. 

 Ornith. (text), I, 1825, p. XXVIII) was the first to designate the 

 type of Hirundo Linnaeus, and he selected Hirundo rustica Linnaeus. 



Bombycilla Vieillot versus Ampelis Linnaeus. (Cf. Committee British 

 Ornithologists' Union, List Brit. Birds, ed. 2, 1915, p. 362.) Change 

 rejected, because the type of Ampelis Linnaeus is not determinable 

 by tautonymy, since, in the 'Systema Naturae,' ed. 12, I, 1766, 

 p. 297, the supposed synonym "Ampelis" is not used in the proper 

 sense of "the Ampelis." Thus Gray's designation (List Gen. Birds, 

 1840, p. 34) of Ampelis cotinga Linnaeus becomes the first fixation 

 of the type of Ampelis. Consequently Bombycilla is left as the 

 earliest tenable name for the Waxwings. 



Dumetella S. D. W. versus Lucar Bartram 1791 and Zimmermann 

 1793. (Cf. Mathews, 'The Auk,' XXXI, No. 1, Jan., 1914, pp. 

 88-91; Richmond, Proc. U. S. Nat. Mus., LIII, Aug. 16, 1917, p. 600.) 

 Change rejected, because neither Bartram nor Zimmermann are either 

 binomial or binary authors accepted by the International Zoological 

 Commission. 



Regulus Cuvier versus Regillus MacGillivray. (Cf. Richmond, Proc. 

 U. S. Nat. Mus., LIII, 1917, p. 620; Mathews and Iredale, Austral
