Appendix to Birds. 



By the agreement of the American Ornithologists' Union a small number 

 of names of genera are set aside because they are nearly but not quite identi- 

 cal witli other names of earlier date. This I have followed under pro- 

 test. The only practicable rule in such cases in my judgment is to regard 

 any two words as different unless actually spelled alike regardless of all ques- 

 tions of etymology. 



In ray judgment the following earlier names should be restored ; 



458. EREMOPHHiA Boie instead of Olocoris, p. 276. 



511. HELMINTHOPHAGA Cabanis, instead of Helmintho- 

 phila, p. 298. 



512. PARUIiA Bonaparte, instead of Compsothlypis, p. 299.
