448 Supplement to the A. O. U. Check-List. aves 
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 Lovia curvirostra from Loxia as the monotypic 
type of Crucirostra Scopoli does not prevent the same species from 
later Weing designated as the type of Loxia. Furthermore, Loxia 
curvirostra is by tautonymy the type of Loria Linnaeus. 
Passerina Vicillot versus Linaria Bartram 1791 and Zimmerman 1793. 
(Cf. Mathews, ‘The Auk,’ XXXI, No. 1, Jan., 1914, pp. 88-90; 
Richmond, Proc. U. 8. 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.’ XXXIJ, No. 1, Jan., 1914, pp. 88, 90; Richmond, Proce. 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, Dee. 15, 1910, p. 501.) Change rejected, because 
Forster did not actually fix the type of Hirwndo Linnaeus when pro- 
posing (Syn. Cat. Brit. Birds, 1817, p. 17) for Hirundo rustica 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 
Ornithologist’s 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 BPombycilla is left as the 
earliest tenable name for the Waxwings. 
Dumeteila 8S. 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 Zimmerman 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-
