to; but the habits of both are probably exceedingly similar, if not identical. 

 They are known to the natives under the name of " Speckled-hawks." 



Astur atricapillus (Wils.) Bon. Goshawk. " Partridge-hawk." 



Astur palumbarius, Aud., Birds Amer. ii. 95, pi. 23. 

 Astur atricapillus, Cassin, Gen. Rep. 15. 



I obtained a single specimen of this hawk, in immature plumage, from a 

 small collection of skins offered for sale by the natives. They know it as the 

 "Partridge-hawk," but further than this I learned nothing respecting it. It 

 does not appear to be abundant. 



Akchibuteo Sancti-Johannis (Grin.) Gray. Black-hawk. 



Archibuteo Sancti-Johannis, Cassin, Gen. Rep. 33. 



While at Puffin Island, on Groswater Bay, I twice saw a large hawk that I 

 supposed to be this species. It was hovering at a great height over the island, 

 and constantly uttered its loud, piercing screams. I was unable to secure this 

 specimen, which was the only one I observed during my stay in Labrador. 



Aquila Canadensis (Linn.) Cassin. Golden Eagle. " Grepe." 



Aquila chrysatos, Aud., Birds Amer. i. 50, pi. 12. 

 Aquila Canadensis, Cassin, Gen. Rep. 41. 



An intelligent hunter, whom I questioned concerning this Eagle, informed 

 me that, though he knew it well, it was very rare, and very seldom obtained. 

 His description was so exact, that I had no difficulty in determining that the 

 present species was referred to, and not the ffallicetus albicilla, concerning 

 which, though it may be found in Labrador, I could learn nothing. He applied 

 to the A. Canadensis the name of "Grepe," or "Greep," the derivation of 

 which word I was unable to ascertain. 



Bubo Virginianus (Gm.) Bon. Great Horned Owl. 

 Bubo Virginianus, Aud., Birds Amer. i. 143, pi. 39. Cassin, Gen. Rep. 49. 



A single specimen of this bird which I saw at Rigolet, made me aware of its 

 existence in Labrador. I learned nothing of its habits ; which, however, in 

 all probability, do not differ materially from those of the more southern bird. 



Picoides arcticus (Sw.) Gray. Arctic Three-toed Woodpecker. 



Picus arcticus, Aud., Birds Amer. iv. 266, pi. 268. 

 Picoides arcticus, Baird, Gen. Rep. 98. 



I did not myself meet with any individuals of the Three-toed Woodpecker ; 

 but I saw a specimen in a collection of skins made by the natives. It is pro- 

 bably not rare in the interior. 



Ceryle alcyon (Linn.) Boie. Belted Kingfisher. 



Alcedo alcyon, Aud., Birds Amer. pi. 77 

 Ceryle alcyon, Baird, Gen. Rep. 158. 



I ascertained the existence of this bird in Labrador, from a single skin in the 

 possession of the natives. They considered it as a rare bird. 



Turdus (Turdus) Alicia Baird. Grey-cheeked Thrush. 

 Turdus (Turdus) Alicios, Baird, Gen. Rep. 217. 



I was not a little suprised to find this species breeding abundantly in Lab- 

 rador, its habitat being given by its describer as "the Mississippi Region to 



1861.]
