EIGHTH SUPPLEMENT TO THE AMERICAN ORNITH- 

 OLOGISTS' UNION CHECK-LIST OF 

 NORTH AMERICAN BIRDS. 



Two YEARS have elapsed since the publication of the Seventh 

 Supplement to the A. O. U. Check-List of North American Birds, 

 during which period the Committee on Classification and Nomen- 

 clature has held three sessions, — one in Cambridge and two in 

 Washington. Five of the decisions reached by the Committee 

 at its first Washington meeting were incorporated in the second 

 edition of the Check-List, published in December, 1895. These 

 are included below with the others, and are distinguished by an 

 asterisk prefixed to the marginal number of the species. In the 

 subjoined list are included all of the cases published in ' The 

 Auk' for January, 1897, they having come before the Committee 

 at its last session, in proof sheets of this number of 'The Auk'. 



As heretofore, the numbers at the left of the scientific names 

 facilitate collation with the Check-List. The interpolated spe- 

 cies and subspecies are numbered in accordance with the provi- 

 sion made therefor in the Code of Nomenclature (p. 14, last 

 paragraph) .
