Sascatchawan river, and the streams that flow into Hudson's 
Bay. 
T. Phasianellus. Like the last mentioned, is not seen west of 
the Rocky Mountains. It abounds on the dry undulating cop- 
pices or prairies of Sascatchawan river, throughout the whole 
chain of that stream. On the shores of Oxford lake this is the 
most common bird of the tribe. 
T. Cupido. In August 1827 I killed several birds of this spe- 
cies between Red river and Pembina in 49° north latitude. This 
may, perhaps, be found to be its most northern range. -It did 
not come under my observation on the western parts of the 
continent, ieee

s bellus. Perhaps no one of the genus extends over such 
a tract of country, and no one is more varied in plumage than the 
- present bird. In the valleys of the Rocky Mountains, 54° north 
latitude, and a few miles northwards near the sources of Peace 
river, a supposed variety of this species is found,—different from . 
T. Umbellus of Wilson. On comparing my specimens from that 
country with some which I prepared in the States of New York 
and Pennsylvania, and on the shores on the chain of lakes in 
Upper Canada, L find the following; differences. Ent. the north- 
mixed gray, having little of that Meis iim: so conspicuous in 
the southern bird :—secondly, the ruffle consists invariably of 
ae 20 feathers, these short, black, and with but little azure 
glossiness ; the crest-feathers are few and short. Should these 
racte reafter be considered of sufficient importance for 
ee a distinct. species, it might perhaps be well to call it
