PREFACE TO REVISED EDITION. 



In the present edition of the Color Key the body of the book, aside from 

 the correction of typographical errors, remains as it was in the preceding 

 edition. The Systematic Table has been reset and brought up to July, 1912, 

 the date of the publication of the latest supplement to the third edition of 

 the American Ornithologists' Union's 'Check-List of North American Birds.' 

 Two Appendixes are added. The first includes all the changes in nomencla- 

 ture and descriptions of new birds which have been accepted by the A. O. U. 

 Committee on Classification and Nomenclature since the publication of the 

 Color Key in 1 903 ; the second contains a list of f aunal ornithological papers 

 which it is hoped will add greatly to the reference value of the book.
