when he took up the keeping of the records, and that they may prove to be Snow Buntings, which is very likely. Mr. D. M. Scott, at Sumburgh Head, writes under date of Oct. 11th, "a number of small birds killed on balcony: picked up four Green Linnets and two Chaffinches. I discovered to-day what becomes of them after being killed. In a hole of a stone dyke I found a large number of wings and legs of small birds, taken there by Weasels" (_i.e._, _Mustela erminea_, which was introduced to Shetland. The Common Weasel, _Mustela vulgaris_, is not an inhabitant of Shetland). If Mr. Scott would in future collect all the wings and send them to me by post, they would be useful in identifying species; or, at any time, if a rare bird occurs, the name of which is not known, the wings, might be sent (see addition to letter of instructions, issued 1884). Mr. Agnew notes that he had never before witnessed such a large migration at Isle of May, with a due S. wind, as that of Oct. 13th, 14th, and 15th. Chaffinch was heard singing on Feb. 28th at Dunipace. Corvidæ.--I have records every month in the year but June. In January, 1884, one Hooded Crow flying north, W.S.W. gale, clear. In February, 1883, records of Grey Crows, Jackdaws (at Isle of May, "very rare" on 13th and 14th, light S. and S.W., shifting to N). Rooks (at Isle of May, on. 19th, a single bird). In March, Rooks (at Pentland Skerries a flock all day, fresh S.E., cloudy), and one Hooded Crow (on 19th at Isle of May, light, S.E.). In April, at Sumburgh Head, Bell Rock, and Isle of May, Rooks and Carrion Crows and one Hooded Crow; prevailing winds S.E., clear. One Black Crow flying north at Noss Head, with light N.W. and clear. In May two records only at Sumburgh Head on 3rd, and at Pentland Skerries, on 11th, of Rooks (two flying W., fresh W. breeze and clear).
