70. Chapman on the Nomenclature of North- American 

 Birds. 



[List of Additions to the North-American Avifauna and of Elimina- 

 tions and Changes in Nomenclature proposed since the publication of the 

 A. 0. U. Check-List. By Frank M. Chapman. The AiA, v. p. 393.] 



The title of this important memoir indicates its scope and 

 object, which, liowevei', is more fully set out in Mr. Chaj)- 

 man's few prefatory remarks. He says, '' since the publication 

 of the '^ Check-List ^ in March 1886, tbe additions and cor- 

 rections to our avifauna have been so numerous, that it has 

 been considered advisable to collate tbem, and the following 

 compilation is presented with a hope that it may be of 

 some service to the many workers in North- American 

 Ornithology.^^ 



It may be as well to add that the compiler has made it an 

 object to include all the additions and changes which have 

 been made without reference to their tenability. 



71. Cooke on the Birds of the Mississippi Valley. 



[Report on Bird-Migration in the Mississippi Valley in the years 1884 

 and 1885. By W. W. Cooke. Edited and revised by Dr. C. Hart 

 Merriam. Washington: 1888.] 



The present report, the first-fruit of the cooperative labours 

 of the Division of Economic Ornithology of the Department of 

 Agriculture and of the Committee on Bird-Migration of the 

 American Ornithologists' Union, consists of two parts. 

 The first, which contains remarks on the general subject of 

 migration, the influence of the weather, topography and alti- 

 tude, the progression of bird-waves, &c., does not always 

 coincide wiih the views of Dr. Merriam, who expresses his 

 dissent from several theories therein set forth; but the 

 second part, consisting of the systematic report, is a highly 

 valuable collection of facts. The 560 species known to occur 

 in the Mississippi valley are treated serially, the movements 

 of each species during the seasons of 1884 and 1885 being 

 traced with as much exactness as the records furnished by 

 the one hundred and seventy observers in the district permit ;
