This species, if distinct from the Snowy Owl, is absolutely unknown to naturalists, never having been noticed by any traveller since Mr. Hutchins. Though, from the description above quoted, apparently a peculiar species, the same name is given by the natives in the vicinity of Hudson’s Bay, to the Snowy Owl, according to Mr. Hearne (Journey to the Northern Ocean, p. 402. London, 1795, quarto); and it, too, makes its nest on the ground. With so little positive information, it is impossible to form more than conjectures respecting the bird alluded to in the description, and it must be left as an interesting matter of inquiry for future explorers and naturalists. It may be observed with reference to Mr. Hearne’s statement, that if the bird he alluded to was really an Owl, it differs from any other American species in laying from “five to ten eggs.” Careful and evidently accurate statements respecting the incubation of nearly all the northern species, are given by Dr. Hall, in his “Sketch of the Zoology of the District of Montreal” (manuscript in our possession); and no species is represented as producing more than “four to five eggs,” except the Mottled Owl (_Scops nævia_), which lays “five to six.” The Snowy Owl, it is stated by Dr. Hall, lays “two white eggs.” 2.

(1824.) This Owl, which is a rather common South American species, is stated by Vieillot to inhabit America from Cayenne to Hudson’s Bay. His remarks apply, however, to the _Scops asio_ in mottled plumage; though a good plate is given by him of the bird, of which the name is above cited, no specimen of which has ever come under our notice, captured in any part of the United States. 3. Strix Georgica. Lath., Gen. Syn. Supp., p. 15. (1801.) “Size of the Barn Owl; length sixteen inches and a half; bill yellow; the plumage on the upper parts of the bird is brown, banded with yellowish; throat and breast pale brown, crossed with whitish bands; belly yellowish white, marked with longish red brown streaks; thighs and legs woolly, whitish or very pale in color, varied with small blackish spots; quills and tail feathers brown, crossed with four or five white bands. “I met with this specimen in the collection of Mr. Humphries, said to have come from several miles within _South_ Georgia, in America.” (Latham, General Synopsis of Birds, Supplement II., p. 64.)
