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).
