FIFTH REVISED EDITION OF THE 



\ Key to North American Birds, >> 



« 



By ELLIOTT COUES, M. D., Ph. D. 



Wholly new text. Profusely illustrated. Over two hundred new 

 figures of rare species added in this edition, from life studies by 

 Louis Agassiz Fuertes. Bird Lore says of Coues' Key: "It is be- 

 yond comparison the best book on general and systematic ornithol- 

 ogy ever published." The manuscript of this fifth revised edition 

 was completely finished shortly before the death of Dr. Coues, and, 

 though a posthumous work, is one which the author would unques- 

 tionably have been proud to own as the crowning achievement of his 

 life. The proofs have been read by an experienced ornithologist. 



Indispensable to every Student or Sportsman. 

 TWO VOLUMES, CLOTH, NET $10.
