192 Stone, Changes in Generic Names of American Birds. [adHI 



Columbigallina Boie, 1826, becomes Ch^emepelia Sw. — The 

 name Columbigallina, usually cited from Boie, was first used by 

 Oken (1817) in the Cuvier review already referred to, and was 

 based upon "La Colombi Gallin" of Levaillant, which is Columba 

 carunculata Temm. and Knip, an unidentifiable bird. This name 

 disposed of, we fall back upon Chcemepelia Sw., Zool. Jour., Ill, 

 p. 361, 1827, for the Ground Dove, the type (first species) being 

 Columba passer ina Linn. 



Ardetta Gray, 1842, becomes Ixobrychus Billberg, 1828. — 

 Billberg, Synop. Faun. Scand., Aves, p. 166, proposed Ixobrychus 

 for Ardea minuta and A. stellaris of Linnreus, the former being the 

 type by the first species rule the name wall replace Ardetta Gray, 

 1842, of the Check-List. 



Iache Elliot, 1879, becomes Cynanthus Sw. 1827. — Cynanthus 

 first appeared in the Philos. Magazine, I, p. 441, 1827, not Zool. 

 Jour., Ill, p. 357, whence it is usually quoted (cf. Oberholser under 

 Ammodramus below). The type (first species) is C. latirostris 

 Sw. and the name will replace Iache Elliot, 1879, of the Check- 

 List which is based upon the same species. 



Megascops Kaup, 1848, becomes Otus Pennant, 1769. — Cf. 

 Stone, Auk, 1903, p. 275. 



Glauciditjm Boie, 1826, becomes NoctuaS. G. Gmelin, 1771. — 

 Noctua was first used in a generic sense by S. G. Gmelin, Nov. 

 Com. Sci. Petr., XV, p. 447 (1771), the only species mentioned 

 being "Noctua minor Briss." He states that his bird is rather 

 smaller than that described by Brisson, and from the locality it is 

 clear that it was the Strix passerinum of Linnaeus. It may be 

 claimed that Brisson's name was based upon the little owl of south- 

 ern Europe, Athena noctua (Scopoli), but while he no doubt confused 

 the two species, as did Linnseus, the majority of references are 

 identical in the two cases and both names have been restricted to 

 the northern species so far as their application is concerned. 



As Glaucidium Boie, Isis, 1826, p. 970 is based upon Strix pas- 

 serinum it is obvious that it must become a synonym of the earlier 

 Noctua S. G. Gmelin. 



Trogon Linn. 1766, becomes Trogon Brisson, 1760. — Type 

 remains the same. 



Contopus Cab. 1855, becomes Horizopus Oberh. 1S99.— Cf. 

 Oberholser, Auk, 1899, p. 331.
