Capt. Blakiston on the Birds of the 
CONTOPUS VIRENS. 
The Wood-Pewee is given by Richardson in the Appendix to 
Back's ‘ Voyage.' There is also a specimen from Northern 
Minnesota in the collection of the Smithsonian Institution. 
30. Empidonax pusillus. 
Besides my specimen killed at Fort Carlton, on the Saskat- 
chawan (‘ Ibis,' vol. iv. p. 4), the f Fauna Bor.-Am.' records one 
from the same place, and Mr. Bernard Ross notices it on the 
Mackenzie. 
Empidonax traillii. 
Empidonax minimus. 
Both these Flycatchers are given by Mr. Bernard Ross as 
summer visitors to the Mackenzie River, the latter the more 
common. 
Of the Thrushes, Turdus pallasii (the Hermit Thrush) 
stands first in order; but its occurrence in the interior is at 
present uncertain, as Mr. Ross is doubtful concerning a specimen 
collected by him on Mackenzie River. In the ‘ Fauna Bor.-Am.' 
there has been a jumble about the Thrushes: Professor Baird 
considers the description of Merula wilsonii, and the figures 
of M . solitaria (pi. 35) and M. minor (pi. 36), of that work, to 
belong to Turdus swainsonii (Cab .); while the description only 
of M. solitaria, given as from Lake Huron, refers to T. pallasii, 
the true Hermit Thrush. 
Turdus fuscescens. 
A specimen from the Lower Saskatchawan, mentioned in the 
‘ Fauna Bor.-Am.' as Merula minor, and another from Red River 
Settlement, in the Smithsonian Institution, place Wilson’s 
Thrush as an inhabitant of the region treated of in this paper; 
but, for my own part, I did not obtain a specimen. 
31. Turdus swainsonii. 
On account of the confusion which existed between the three 
species, T. fuscescens, T. ustulatus, and the present one, my speci¬ 
men (‘Ibis,' vol. iv. p.4) was carefully compared with a typical one 
given me by Professor Baird. I shot another at the same time 
at Fort Carlton, which, being a male (the sex of No. 99 could not 
be distinguished on account of the penetration of the shot) ;
