Preface 



vn 



many corrections, changes, and additions which have materially increased its 

 value, but has permitted me every opportunity of examining the collection of 

 birds in his charge. Mr. Frederic A. Lucas, Head Curator of the Brooklyn 

 Museum of Arts and Sciences, has read portions of the manuscript, and made 

 valuable suggestions, and has also written the chapter on the "Anatomy of Birds." 

 Mr. J. H. Riley, of the United States National Museum, has called my attention 

 to a number of things that might otherwise have been overlooked, and Dr. C. 

 William Beebe, of the New York Zoological Garden, has been of great assistance 

 in securing and reproducing the figures. To Mr. Robert Ridgway, Curator of 

 Birds in the United States National Museum, I was indebted for many valuable 

 suggestions, especially in regard to classification, before it was known that he 

 was to edit the book. Since the completion of the work he has read the manu- 

 script and suggested certain changes and slight revisions of statement, the extent 

 of his work being indicated in the Editor's Preface which precedes. To these and 

 all others who have assisted in the preparation of the book, I make grateful 

 acknowledgment.
