INTRODUCTION 
Cn 
The nomenclature ‘is in the main the same as followed by the 
American Ornithologists’ Union Check-List, but we have copied 
the order given in Sharpe’s “‘ Handlist ” as far as it is published. 
The order followed beyond where his work remains unpublished, 
is approximately that to be used by Dr. Robert Ridgway in his 
forthcoming work, and it is through his kindness that we are here 
allowed to make usevof it. We have also made various changes in 
orthography for the sake of consistency. 
The authors wish to express their sincere thanks to Drs. Walter 
Faxon and Charles W. Townsend, and to Messrs. William Brewster, 
George H. Mackay, Henry B. Bigelow, Manton Copeland, Arthur 
C. Bent, Julius R. Wakefield, Robert O. Morris, Charles E. Ingalls, 
Carle haimey, Jr. HH. V. Greenough, F. H. Allen, Outram 
Bangs and others, who have assisted them materially in their 
work.
