breeding of many species, he having made the Oology of this 
locality a specialty ; and from Messrs. John Hammond, John C. 
Allison, Peter Camphell, Frederick W. Daniel, Alfred 
Morrisey, and W. N. Gould I have received valuable informa- 
tion. 
I have also to thank James H . Carnall, Taxidermist, of this 
City, and xMr. George A. Boardman, of Saint Stephen, for use- 
ful notes, and regret that an offer kindly made me by Mr. Board- 
man to place at my service the result of his extensive observations 
in this Province did not reach me until the manuscript of the 
Catalogue was in the hands of the printer. 
I will take this opportunity of expressing the thanks I owe 
Professor Spencer F. Baird and Mr. Robert Ridgway of the 
Smithsonian Institution, Washington, for courteously rendered 
assistance in identifying unknown species, and for other favors ; 
and I am also deeply indebted to Mr. William Brewster, of 
Cambridge, and Mr. E. O. Damon, of Northampton, Mass., for 
similar kind services ; nor can I forget to make mention of the 
valuable information received from Mr. H. A. Purdie, of Boston, 
whose friendly aid merits my best thanks. 
In writing the Catalogue, I have copied the names and ar- 
rangement of the species adopted by Mr. Ridgway for the 
“ Nomenclature of North American Birds,” issued by the 
Smithsonian Institution in 1881. In species that have a local 
name differing from the common name of the “ Nomenclature,” I 
have added the local name, and placed it in quotation marks.
