GENERAL NOTES. 



Ixoreus should replace Hesperocichla. 



Baird proposed the name HesperocicJila (Review Amer. Birds, I, 12, 

 1864) for the Varied Thrush on the ground that Bonaparte's term Ixoreus 

 (Comptes Rendus, XXXVIII, 3, note, Jan., 1854) was founded on some 

 South American member of the family Tyrannida. Bonaparte's refer- 

 ence, however, will show that while he may have associated Gmelin's 

 Turdus ncevius with a bird of some other family, it is yet plain that his 

 term was based upon Gmelin's name, and that in future Ixoreus should 

 be used for the genus now called Hesperocichla. Bonaparte's reference is 

 as follows: "Malgr6 les efforts de plume et de pinceau du celebre orni- 

 thologiste Audubon, le Turdus ncevius, Gm. {Orpheus meruloides, Sw.), 

 n'est pas un Grive "ni meme un Chanteur, mais un Volucre Teniop- 

 terien, type de mon nouveau genre Ixoreus.''^ 



The two recognized forms should hereafter be called Ixoreus ncevius 

 (Gmelin), and Ixoreics ncevius meruloides (Vigors). — Charles W. Richmond. 



Two preoccupied avian genera. 



Aphobus Cabanis (1851), for a South American icterine bird is preoc- 

 cupied by A2)hobus Gistel (Naturgesch, XI, 1848), and may be renamed 

 Aaptus (type, Agelaius chopi Vieillot). 



Floricola Elliot (1878), as a genus of Hummingbirds, is preoccupied 

 by Floricola Gistel (Naturgesch, XI, 1848). In its place may be substi- 

 tuted Anthoscenus (type, Troehilus longirostris Vieillot). — Charles W. 

 Biclimond.
