58 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 ' Fauna Bor.-Am.' records one 

 from the same place, and Mr. Bernard Ross notices it on the 

 Mackenzie. 



Empidona^s. 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 Saskatchawai, 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)^
