In the Catalogue of Canadian Birds, of which this is the first 
part (pp. 1-218) it is intended to enumerate all the birds of the 
Dominion systematically and to bring together the principal 
known facts in regard to their distribution, migrations and breed- 
ing habits. It is intended to complete the Catalogue in a second 
part, which will be prepared and published as soon as possible.
