SUMMARY OF CHANGES, ADDITIONS AND 



ELIMINATIONS IN THE PRESENT 



EDITION OF THE CHECK-LIST 



AS COMPARED WITH THE 



THIRD EDITION. 



Rather than prepare a supplement to the Check-List for pubUcation in 

 'The Auk' the Committee has thought best to present a Ust of all changes 

 in nomenclatui'e, additions, and eliminations as an appendix to the Check-Ijst 

 itself where it will be available for convenient reference while in some cases 

 this information has been added also in footnotes to the main text. 



By referring to the index any name contained in the last edition which is not 

 found in the present Check-List may be located in this appendix where an 

 explanation of the change, elimination, etc., is given.

 by families is as follows:
