irregular in its breeding habits, nesting from the end of May to July or August.  In Burhou the Storm Petrel bred mostly in holes in the soft black mould, which was also partly occupied by Puffins and Babbits, but occasionally under large stones and rocks.  We did not find any breeding on the islands to the north of Herm, but they may do so occasionally, in which case their eggs would probably be mostly placed under large rocks and stones, where the Puffins find safety from the attacks of the various egg-stealers.  At other times of year than the breeding-season, the Storm Petrel can only be considered an occasional storm-driven visitant to the Islands.

It is included in Professor Ansted’s list, and marked as occurring in Alderney, Sark, Jethou, and Herm.

With this bird ends my list of the Birds of Guernsey and the neighbouring Islands.  It contains notices of only 176 birds, 21 less than Professor Ansted’s list, which contains 197; but it seems to me very doubtful whether many of these 21 species have occurred in the Islands.  I can find no other evidence of their having done so than the mere mention of the names in that list, as, except the few mentioned in Mr. Gallienne’s notes, no evidence whatever is given of the when and where of their occurrence; and we are not even told who was responsible for the identification of any of the birds mentioned.  I have no doubt, however, that any one resident in the Islands for some years, and taking an interest in the ornithology of the district, would be able to add considerably to my list, as Miss C.B.  Carey, had she lived, would no doubt have enabled me to do.  I think it very probable, mine having been only flying visits, though extending over several years and at various times of year, I may have omitted some birds, especially amongst the smaller Warblers and the Pipits, and perhaps amongst the occasional Waders.  There is one small family—­the Skuas—­entirely unrepresented in my list; I am rather surprised at this as some of them, especially the Pomatorhine—­or, as it is perhaps better known, the Pomerine—­Skua, Stercorarius pomatorhinus, and Richardson’s Skua, Stercorarius crepidatus, are by no means uncommon on the other side of the Channel, about Torbay, during the autumnal migration; but I have never seen either species in the Island, nor have I seen a Channel Island skin, nor can I find that either the bird-stuffers or the fishermen and the various shooters know anything about them.  I have therefore, though I think it by no means; unlikely that both birds occasionally occur, thought it better to omit their names from my list.

Professor Ansted has only mentioned one of the family—­the Great Skua, Stercorarius catarrhactes,—­in his list, which also may occasionally occur, as may Buffon’s Skua, Stercorarius parasiticus; but neither of these seem to me so likely to occur as the two first-mentioned, not being by any means so common on the English side of the Channel.
