In November and December the greatest movements are noticed, which I give in detail:--Nov. 2nd, Pentland Skerries, several Kittiwakes flying S.E., noon; fresh S.W. Nov. 10th, Isle of May, thousands of Gulls (?); W. gale, clear; first seen at 4 a.m., wind shifting to north. Nov. 11th, Isle of May, all the above gone; light N.W., clear. These may have been Glaucous, from description, but this is not clear; and from subsequent records I have preferred to consider them Herring, though Mr. Agnew includes the latter later by name, I believe Mr. Agnew knows the Glaucous and Iceland Gulls well. _Land Note._--There has not been a large migration of Glaucous and Iceland Gulls at Kincardine on Forth for many years. Nov. 17th, Isle of May, hundreds of Herring Gulls came from S.E. all day; light N.W. "Grey Gulls" mixed with Blackbacks, the latter one in twenty. Nov. 18th, Isle of May, every Gull gone; light N.W. Nov. 24th, Isle of May, hundreds of Herring Gulls came from S.E. all day; fresh W.; also accompanied by smaller numbers of Black-backs. Dec. 13th, Pentland Skerries, two Black-backed Gulls on island, 12.30 p.m.; N.W. gale. Dec. 3rd, Isle of May, thousands of "Gulls," 3 p.m.; W., clear. 1884, Jan. 22nd, Isle of May, large light-coloured Gulls with black tips to wings; gale W. last night. _Note._--There is evidently considerable confusion existing regarding the various species of Sea Gulls; and this is not to be wondered at when the innumerable phases of plumage in even the same species, according to maturity or immaturity, is considered. What is sadly wanted in such a quest as ours is a series of cheap yet fairly well executed plates of birds in all phases of plumage, with measurements to scale; but the almost impossibility of issuing such at a sufficiently low price for general distribution must, we fear, for ever debar our correspondents from obtaining such a means of assistance. M. De La Rue issues marvels of cheapness in Christmas Cards; could he not undertake something in this line? His pictures of birds are admirable, but he would have to keep up the standard, or even improve it, to be of scientific value to us. Procellariidæ.--Records scarce in spring and autumn. At Auskerry, arrived for first time on July 30th, but as early as 6th eggs were laid at Pentland Skerries. Being a bird of nocturnal habits, the arrival cannot, we fancy, be easily fixed at all times. At Auskerry, on 8th, two pairs had two eggs each (some notes on the schedule margin here have been torn off and lost, J. A. H. B.) On Sept. 25th one struck at Dunnet Head; S.S.W., fog; and on 26th six struck and rested from 9 to 11 p.m.; S.E. fresh, and haze. It is seldom so many are recorded at the same time. Are these Pentland Skerries birds? At Noss Head, on Aug. 28th and on 30th, one Stormy Petrel each time struck, but not killed, with W.N.W. fresh on former date, and light S.E. and haze on latter.
