PREFACE 5 



works have been included, but no name published later than 

 1915 has been considered. 



In this index, volume and page numbers are separated by 

 periods. The 1, 2, and 3 following "Richmond" indicate, respec- 

 tively, the 1902, the 1909, and the 1917 lists by Richmond. Clar- 

 endon figures indicate principal references, the other figures 

 indicate synonyms or minor citations. Subgeneric names from 

 Gray are treated the same as generic names. The spelling (pf 

 the names is that of the work or works cited. The dagger (t) 

 is used to designate genera of fossil birds. 



Example. — Acanthochasra is the name of a genus of recent 

 birds. It is cited by neither Bonaparte nor Gray; is given as 

 a valid genus in the Catalogue of Birds, Volume IX, page 262; 

 is given as a valid genus by Sharpe, Hand-list, Volume V, page 

 89, and as a synonym on page 90; is given as a synonym by 

 Dubois, Synopsis Avium, page 724; and is given in none of 

 Richmond's lists. 



In the preparation of the copy the names with their re- 

 spective page numbers were copied from each book and the writ- 

 ten list was checked by the book. The names were then sorted 

 alphabetically, bringing together the slips for each name and 

 eliminating duplicates where there were two or more page ref- 

 erences for a name in one author. By this combination and 

 elimination the 25,000 original slips were reduced to a manage- 

 able number. There are 8,839 names in this index; 2,221 of 

 these occur in Bonaparte's Conspectus, 5,725 in Gray's Hand- 

 list, 5,380 in the Catalogue of Birds, 3,073 in'Sharpe's Hand- 

 list, 5,585 in Dubois's Synopsis, and 2,737 in Richmond's three 

 lists. 



This index should facilitate the location of any generic name 

 in the volumes that are constantly used by every worker in 

 taxonomic ornithology; if it does that, no more is asked.
