CHECK LIST 



— OF — 



NORTH AMERICAN BIRDS 

 AND CODE OF NOMENCLATURE, 



Being the Report to the Union of the A. O. U. Committee 



on Classification and Nomenclature of North 



American Birds. 



The Report consists of two Parts, of which Part I is the new Code of Nomen- 

 clature recently adopted by the Union. This is an elaborate exposition of the 

 Rules of Nomenclature by which the Committee was guided in deciding the 

 names of North American Birds as given in the accompanying Check List. 



Part II is a Classified List of North American Birds, giving the names of the 

 higher groups, as well as of the species and subspecies, from subgenera to 

 orders. The names of the genera and subgenera are accompanied by references 

 to the work or paper in which they were first established ; the names of the 

 species and subspecies are followed by a citation of the publication where they 

 were first described, and of the authority (when not also the original describer) 

 who first used the name as adopted in the List. 



A Concordance is given of the previous Check Lists, as Baird's (1858), Coues's 

 (1872), Ridgway's (1880), and Coues's second List (1S82) ; to which is added a 

 brief statement of the geographical distribution of each species and subspecies, 

 with special reference to its North American range. 



The List, besides being the ' latest,' and an authorized ' standard ' List, em- 

 braces two features not found in any previous List of North American Birds, 

 inasmuch as it gives the Classification and the Habitat of each bird included. 



The Code and List is the result of the expenditure of much time and research 

 on the part of the Committee during the last two years. In many respects 

 the List will doubtless prove more satisfactory, and in some ways of far greater 

 utility, than either of its several excellent predecessors. 



The work, making an octavo volume of about 300 pages, is printed on fine 

 paper, and no care has been spared to make it typographically attractive and 

 accurate, the work having been printed at the University Press, Cambridge. 



Price, in full cloth, $3.00, postpaid.
