As promised in a prefatory note to the second part of the 

 Catalogue of Canadian Birds, Part III of this work is issued the 

 present autumn. The original intention in preparing a Catalogue 

 of Canadian Birds was to complete the work in two parts, but the 

 large amount of valuable information, which had become available 

 by the time Part II was finished, rendered a third part necessary. 

 This part entirely completes the work for the present ;• but the 

 additional knowledge of our birds which will no doubt accumulate 

 in the next few years may necessitate further publications on this 

 subject in the future.
