Lake, Fort Simpson on the Mackenzie River, Nulato on the 

 upper Yukon, and British Columbia. 



E. t. ahwnwi breeds in the Maritime Provinces, New England 

 and New York, the northern part of the Lower Peninsula of 

 Michigan (I have several typical specimens from Oden which is 

 situated about twenty miles south of the Straits of Mackinac), and 

 doubtless at many other points in the region lying immediately 

 about the Great Lakes, but just how far to the westward it extends 

 and whether or not its breeding range in the Mississippi Valley 

 reaches sufficiently far southward to impinge on or closely 

 approach that of true traillii, I am wholly ignorant. 



SEVENTH SUPPLEMENT TO THE AMERICAN ORNI- 

 THOLOGISTS' UNION CHECK-LIST OF 

 NORTH AMERICAN BIRDS. 



Since the publication of the Sixth Supplement to the A. O. U. 

 Check- List the Committee on Classification and Nomenclature of 

 North American Birds has held two sessions, having in hand 

 the preparation of a new edition of the Check-List, as well 

 as current questions relating to species and subspecies, and to 

 changes in nomenclature proposed since the preparation of its 

 last report {cf. Auk, XI, 1894, pp. 46-51). The sessions of the 

 Committee were held in Washington. Jan. 15-18, 1894, and Feb. 

 12, 13, 1895, all the members of the Committee being present. 

 In view of the proposed early publication of the second edition 

 of the Check-List, all questions known to the Committee were 

 considered, including nearly all of those originating in the present 

 (April) number of ' Hie Auk.' Some of the latter still await final 

 action.
