Bay Algse,” by Marshall A. Howe, Assistant Director of the New York 
Botanical Garden, pages 1-30, PL 2. This paper completes the nine 
parts of volumes IV and V of the Arctic botanical reports, and an index 
of the whole botanical section has been prepared, and will soon be issued. 
Museum Bulletin No. 48, Biological Series No. 13, “A Study of Buteo 
Borealis, the Red-tailed Hawk, and Its Varieties in Canada,” by P. A. 
Taverner, pp. 1-20, 3 coloured plates, was issued November 11, 1927. 
R. M. Anderson made considerable progress on a Check-list of Canadian 
Mammals, of which he has found about 470 forms recorded from the Dom- 
inion of Canada, including the Dominion of Newfoundland and its Labrador 
mainland section, which is similar to Quebec from the zoological standpoint. 
There has been no complete modern list of the mammals of Canada as 
a whole, and it should be of some value to students and others to have 
the English, French, and Latin names of the species found in the different 
districts, with lists of the type localities, and the ranges and habitats of 
the different species. Additional data is solicited from persons having 
records of the rarer species or of spread of any species. 
P. A. Taverner has been working during the year on a monograph of 
the sea-birds of Canada, having extended the scope of this work to include 
the sea-birds of the Pacific coast as well as the Atlantic, as was originally 
intended.
