I have always regarded this bird as an accidental visitor to England, Scotland, and Ireland; but Mr. J. H. Dunn informs me that forty-five years ago it bred every year on the hills about four miles from Strom- ness, and Mr. Robert Gray says it may almost be regarded as a regular spring visitant to the Hebrides. _ Its great size and powerful claws indicate that quadrupeds of considerable bulk are within the compass of its destructive powers ; and hence the hare, the lemming, white grouse, and the ptarmigan have but little chance of escape when once enclosed within the grasp of its talons. Its proper home is the icebound regions of the north; in Lapland it follows the lemmings in their migration southwards. “So little has been published in England,” says Professor Newton, when exhibiting some rare eggs at a meeting of the Zoological Society (Dec. 10, 1861), “ respecting the Snowy-Owl’s manner of nidificatmoneghen I hold myself excused for presenting the information I have been able to collect on the subject: gene According to Herr Wallengren, Professor Lilljeborg, on June 3rd, 1843, found on the Dovrefjeld a nest of this bird containing seven eggs, placed on a little shelf on the top of a bare mountain far from the forest and easy of access.
