PREFACE. 



Three years have elapsed since the publication of Part I of this 

 Catalogue. During that time many further facts have been 

 gathered and recent publications received, so that the part now 

 published will give a somewhat more comprehensive sketch of 

 the geographical distribution than was possible when the first 

 part was published. 



Our knowledge of the avi-fauna of Alaska, northern British 

 Columbia, Labrador and the Hudson Bay region has been very 

 much increased by the valuable papers mentioned in the accom- 

 panying list.. Certain omissions were also made in the list of 

 authorities which are included in this. 



Mr. Spreadborough has been busy during the past three sum- 

 mers, and has as usual added much to our knowledge of the whole 

 fauna in the districts where he has been at work. The summer 

 of 1900 he spent in Algonquin Park, Ont., under the direction of 

 the writer ; in 1901 he collected in the Coast Range, B.C., chiefly 

 around Chilliwack Lake ; and in 1902 between Trail and Cascade 

 on the International Boundary, B.C. During these two seasons 

 he collected under the direction of Mr. J. M. Macoun, Naturalist 

 to the Boundary Commission. Many of the observations credited 

 to Mr. Spreadborough were made by the writer, but as the work 

 was done in company and all the specimens collected by Mr. 

 Spreadborough, some confusion and repetition has been obviated 

 by the omission of the author's name for the years when Mr. 

 Spreadborough was with him. The same may be said of Mr. 

 J. M. Macoun for the years 1901 and 1902 when Mr. Spread- 

 borough acted as his assistant. 



Valuable manuscript notes have been received from Mr. C. R. 

 Harte ; Mr. Harold Tufts, Wolfville, N.S. ; Mr. W. H. Moore, 

 Scotch Lake, N.B. ; Mr. J. Hughes-Samuel, Toronto, Ont. ; and 

 Mr. J. H. Fleming, Toronto, Ont., and many additional ones from 

 soms of the gentlemen mentioned in Part L 



The manuscript for the remainder of the work isnearly ready 

 for the printer but other duties claim my attention during the 

 coming summer and the remainder of the work will be published
