The present work is, in part, a reprint of the General Report on 

 North American Birds presented to the Department of War, and 

 published in October, 1858, as one of the series of " Reports of Ex- 

 plorations and Surveys of a Railroad Route to the Pacific Ocean." 

 In these volumes, however, will be found many important additions 

 and corrections. The Atlas contains 100 plates, representing 148 

 new or unfigured species of North-American birds. Of these plates, 

 about 50 appear for the first time, having been prepared expressly 

 for this work. The remainder form the ornithological illustrations 

 of the Reports of the Pacific Railroad and United States and Mexi- 

 can Boundary Surveys, and are distributed throughout the numerous 

 volumes composing those series. All have, however, been carefully 

 retouched and lettered for this edition and quite a number redrawn 

 entirely from better and more characteristic specimens. In fact the 

 plates have been prepared expressly for the present edition, with the 

 utmost care, and embrace one hundred species of birds not figured 

 by Audubon. 



In the volume of text will be found a complete account of all the 

 Birds of North America, brought down to the present time, includ- 

 ing accurate descriptions of all known species: their geographical 

 distribution: and, as far as possible, all other information necessary 

 to a complete summary or manual of North-American ornithology. 

 Extended bibliographical notices, embracing full reference to very 

 nearly all authors on American ornithology, have been added, and 

 will be found to be of his*l> "uterest to the student and naturalist.
