Linota borealis = canescens (Gould). 

 Severn House. 



The same bird known in this country as the Mealy Redpoll. 



Loxia leucoptera, (Gmel.) 



Hudson's Bay, Severn House, and Trout Lake Station. 

 Cory thus enucleator (Linn.), (Pine Grosbeak). 



Severn House. 

 Scolecophagus ferrugineus, (Gmel.) 



Severn House, Trout Lake. 



The most northern species, — called Rusty Grakle by Americans. 

 The male is not rusty, but the female has a ferruginous 

 tinge. 



Lanius septentrionalis, Gmel. = borealis of Vieillot, " Orn. Amer. 

 Sept. ;" but he unfortunately gave the same name to a Euro- 

 pean bird in his " Faun. Franc. ;" Gmelin's name, therefore, 

 should stand. It is very difficult to make out the birds of 

 this genus ; and there almost seems reason to look upon the 

 American species as varieties of the European, but ornitholo- 

 gists have accepted them as different. 

 Trout Lake Station and Severn House. 



Tyr annus borealis (Sw.), (T. Cooperi, Bonap.) 

 Hudson's Bay. 



(One specimen.) A rare bird, and to be seen in very few col- 

 lections. 

 Colaptes auratus, (Linn.) 



Trout Lake and Hudson's Bay. 



One of the woodpeckers ; but as it feeds on ants, and therefore 

 does not require so much labour to get its food as the other 

 woodpeckers, its bill is less suited for such work. It is only 



' a summer visitant to the Fur countries. 

 Apternus tridactylus, (Sw.) 



Severn House. 



(One specimen.) The common three-toed woodpecker. 

 Lagopus albus(Qme\.) = L.subalpinus (Nils.), and L.saliceti(Ijess.), 

 of Europe ; and also —L. Scoticus of Britain. ( Vide Jardine.) 



In consequence of Sir William Jardine's desire to procure 

 specimens of this species in the various states of plumage, to 

 assist in elucidating the question which he has started, whether 

 it is not the same as the common grouse of this country, I 

 begged my correspondents to furnish me with a good series of 

 specimens in their plumage at different seasons of the year, 

 and a fine series of lovely skins, beautifully preserved, has ac- 

 cordingly been sent, which have proved of much use to Sir
