INTRODUCTION. 



The following pages contain the Index to the first ten volumes of the Bulletin 

 of the Cooper Ornithological Club, of which only the first volume ( 1899) bears 

 this title, the subsequent nine ( 1900-1908) being known as " The Condor." 

 There have been no special features embodied in this work for the reason 

 that the present chaotic state of the nomenclature of North American birds 

 renders any system based thereupon exceedingly unstable. It has been thought 

 advisable, therefore, to list species and subspecies exactly as they were found 

 to occur in the text, with only minor changes as will be noted herein. The 

 details of the arrangement are as follows: 



1. Authors. — Titles of papers are in chronological order, the abbreviation 

 " Rev." being used to indicate a review of the paper. 



2. Genera. — Species and subspecies are indexed in alphabetical order under 

 their respective genera, the Roman numeral in heavy type indicating the volume. 

 The scientific names used are in the main taken from the " Auk " twenty-five 

 year index; in the vernacular names the possessive has been discarded. 



3. Neiv Species, etc. — A separate list has been made of the new species 

 and subspecies described, and in the body of the Index an original description 

 is indicated by the abbreviation " desc." 



The editor herewith extends heartfelt thanks to Prof. Joseph Grinnell for 

 many valuable suggestions in the work, to his wife, Mary C. Kaeding, for aid in 

 the drudgery of compilation, and to ]\Ir. W. Otto Emerson and Mr. Howard 

 Robertson, committee on ways and means for the publication of this work.
