in the Interior of British North America. 
physical features of this region in the following manner :—“ Hud¬ 
son's Bay " means the coast of that bay; “ between Hudson's Bay 
, and Lake Winipeg," the densely wooded region to the east of 
that lake; “ Saskatchewan Plains/' the high prairie-plains be¬ 
tween the north branch of that river and the international 
boundary; “ Lower Saskatchewan/' the country bordering that 
river below its forks; and “ Bed River Settlement/' the settle¬ 
ment on the river of the same name which flows into the 
south end of Lake Winipeg. 
The observations here do not extend beyond the western edge 
of the Bocky Mountains; whence to the Pacific a distinct fauna 
and flora prevail, which cannot be included with the present. 
Most of the specimens I have collected are in the Boyal Artil¬ 
lery Institution at Woolwich, where they can be inspected by any 
ornithologist. The nomenclature adopted is that given in Pro¬ 
fessor Baird's recent Beport on the Birds of North America, un¬ 
less the contrary is stated. 
Order ACCIPITBES. 
1. Ealco anatum. $ No. 48. A female, from Saskatchewan 
/fri 3 Plains, on Bow Biver, near Bocky Mountains, August 6th, 1858. 
4y Length 19 in., wing 14. Eye brown, feet yellow, bill blue 
horn-colour, cere yellow. 
This species, although extending from Greenland to Cuba, 
has not yet been found on the Pacific slope of North America; 
and Professor Baird, of the Smithsonian Institution, considers 
that the locality of my specimen (longitude 115° W.) is the 
most westerly yet ascribed to this bird. F. nigriceps takes its 
place on the Pacific, but may probably be found in the district 
of Mackenzie Biver in the far north, where the Bocky Mountains 
do not appear to offer so great an impediment to the mingling 
of the fauna and flora of the two sides of the continent as is the 
case to the southward. 
2. Ealco columbarius. 6 No. 64. $ No. 65. North branch 
Saskatchewan Biver, April 6th, 1858. Male: length llgin., 
wing 7-|, tail 5. Legs and feet yellow, claws black; bill horn- 
colour, greenish towards the base.
