The interval which has elapsed since the publication of Part I. 

 of the Catalogue of Canadian Birds has enabled the author to 

 embody in his work the results of observations made during the 

 past three years by members of the Geological Survey staff and 

 others. The concluding part of the Catalogue, which will con- 

 tain an index to the three parts, is almost ready for printing and 

 will be published next autumn.
