GENERAL NOTES. 



Ixoreus should replace Hesperocichla. 



Baird proposed the name Hesperocichla (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 Tyrannidce. 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: "Malgre* les efforts de plume et de pinceau du c&ebre orni- 

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

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

 terien, type de mon nouveau genre Ixoreus." 



The two recognized forms should hereafter be called Ixoreus ncevius 

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



Two preoccupied avian genera. 



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

 cupied by Aphobus 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, Trochilus longirostris Vieillot). Charles W. 

 Richmond.
