tions and observations on the nesting habits of birds within -the 

 Arctic cannot be overestimated. 



In addition to the works specially cited above I have used 

 manuscript lists and notes on nesting habits of birds from Mr. 

 George White, Ottawa ; Rev. C. J. Young, Lansdowne, Leeds 

 Co., Ont.; Mr. J. Dippie, Mr. J. C. Fleming and Mr. Walter Raine, 

 Toronto, Ont.; Mr. William Saunders, London, Ont; Mr. 

 Robert Elliott, Plover Mills, Middlesex Co., Ont.; Mr. P. A. 

 Tavernier, Bracebridge, Ont.; Mr. A. P. Low, Mr. J. M. Macoun, 

 Dr. Robert Bell, Mr. J. B. Tyrrell and Mr. R. G. McConnell, all 

 of the Geological Survey Staff ; and lastly various lists and reports 

 from Mr. Wm. Spreadborough, of Bracebridge, Ont. 



The whole series of the Transactions of the Natural History 

 Society of Nova Scotia ; the Bulletin of the Natural History Society of 

 New Brunswick ; the Canadian Naturalist and Canadian Record of 

 Science, Montreal ; Ottawa Naturalist ; Journal of the Canadian 

 Institute, Toronto, and the Auk, published in New York, have 

 been drawn upon for notices of rare species and local lists by 

 various contributors. 



It is proposed to complete the second part of the Catalogue 

 next winter, and the writer asks ornithologists who may receive 

 the present publication to communicate to him any additional 

 facts they may have observed respecting the birds included in it. 

 Such additions will be attached as a supplement to the second 

 part.
