Interior of British North America. 
1*. Falco anatum. 
Besides my specimen from near the head-waters of the south 
branch of the Saskatchawan River /Ibis/ vol. iii. p. 315), I have 
received the American Peregrine from the west coast of Hudson’s 
Bay; and Mr. Bernard Ross notices it, but says it is rare on the 
Mackenzie. 
2. Falco columbarius. 
With respect to this species, I would correct a typographical 
error which occurs in my former notes / Ibis/ vol. iii. p. 316), 
where the colour of the “ feet, cere, and space round the eye ” 
of a female should be light yellow, in contradistinction to the 
bright yellow of the male, No. 117. This distinction was noticed 
in the case of each of the two pairs which I examined. The bird 
figured in the ‘ Fauna Boreali-Americana/ pi. 25, as F. cesalon y 
is doubtless the Pigeon-Hawk. In my former papers (‘ Ibis/ 
vol. iii. p. 316), I mentioned having obtained eggs of this 
species. Since then, I have seen Part 1 of Dr. Brewer’s ' North 
American Oology/ where he has figured an egg supposed to 
belong to it, but in the letter-press mentions that Mr. Audubon’s 
figure is very different. My specimens prove that Mr. Audubon 
was correct, and that Dr. Brewer has made an unlucky selection 
in taking a specimen when he was only told that a bird which 
was given to him at the same time was the parent, in preference 
to the personal observation of a naturalist of Mr. Audubon’s 
merits. The nest which I found (the parent birds belonging 
to which I shot, and preserved the male) was situated in a small 
clump of willows and aspens on the prairie, not more than ten 
feet from the ground, and contained four eggs. The eggs and 
bird collected by M. Bourgeau corresponded with my own. I 
find that Mr. Bernard Ross obtained this bird as far north as 
the Arctic Circle, on Mackenzie River, and I am glad to see that 
he has also secured the egg. 
Falco candicans, F. islandicus, et F. grcenlandicus. 
The Gyr-Falcon is given in the f Fauna Bor.-Am./ as identified 
by a specimen from Hudson’s Bay, as F. islandicus (Latham); 
* The numbers attached to species refer to my original list (‘ Ibis,’ Nos. 
12 and 13).
