_Snipe._--A distinct "rush" apparent on the great migration night of 5th October, but all other returns light except "numbers all day" at Rhinns of Islay on 18th December. The largest "rush" is recorded at Skerryvore on 5th October, 9.30 P.M. till 3.30 A.M. on the 6th; light S. wind; eight killed on lantern. All other records quite light; and Jack Snipe, only three entries, _viz._, on 8th October at Butt of Lewis, S., fresh; at Skervuile on 6th, light E. and S.; and one killed at midnight of 22d October at Rhinns of Islay. Of Sandpipers, Redshanks, Dunlins, etc., there are only eight records in all in March, May, August (2), September (2), October, and December. Laridæ.--Gulls we only will mention the more important entries. Cream-coloured Gulls (Iceland) [or Glaucous Gulls.--J. A. H.-B.] "seldom seen here," at Rhinns of Islay on January 18th, 1887. February 1886--"Iceland" Gull at same place, flying E., noted as "rare," on 3d; light N. breeze. In May a Richardson's Skua at Lochindaul on 28th, and all day there again on 30th July. Thousands of Black Backed Gulls and other Gulls on 14th September at Rhinns of Islay. "Dirty Allens" at Dhuheartach on 31st October, and all November numbers of Gulls at Skervuile. Iceland Gulls at Dhuheartach on 12th December, and again at Rhinns of Islay on 7th. Terns arrived on 20th May at Barra Head, and a flock stayed a week at Little Ross and then left, after the 14th June. There are only a few scattered records in autumn. The curious unsettled behaviour of Terns, whether Arctic or Common, is a subject worthy of remark during their breeding season. They often occupy and then abandon their nesting places, apparently without any reason, for it is not always that they leave on account of persecution, though they are much more easily affected by persecution than almost any other sea birds. Procellariidæ.--Petrels.--In September several all day at Dhuheartach, and have been seen "flying south for a week past." [This is an interesting note as pointing directly to a periodical migration of the Petrels. Of course how much such may have been simply caused by increase or diminution of food supply is at present difficult to determine.--J. A. H.-B.] In October only two records, but both on 5th and 6th at 11 P.M. and 2 A.M., struck, but were not killed. [They are evidently thus included in the impulse and great migration of this date. It is noteworthy that we have all through our past reports seldom received definitive record of actual migration of the Petrel till now.--J. A. H.-B.] Colymbidæ.--Divers, Northern Divers, Grebes, etc.--In February, one G. N. Diver on 7th at Skervuile. In March, one do. on 24th at same place. In April, no records. In May, two at Lochindaul on 7th, and on 10th at Kyleakin. No more records of G. N. Divers till 23d October, when one was seen at Rona, Skye, "swimming round the island." Then, 16th November, at Skervuile, and December 26th at same place.
