 Dec. 1st, 24th, and 30th (S.W. still overcast), on the latter day 

 very large numbers.

 23rd, one seen (certain). 



T. migratoriu8, Ked-breasted Thrush. — Heligoland, Oct. 14th, 

 N.W., windy and rain, one seen in cliff, quite close. 



T. merala, Blackbird. — Spring, 1884 : At the Northumber- 

 land stations from March 14th to 20th, many, wind W. and 

 S.W. Orfordness l.h., May 18th, 6 p.m., three struck. 

 Autumn : Great Cotes, Sept. 12th, some young cocks. At 

 numerous stations between the Farn Islands and Hanois l.h., 

 Guernsey, in October, and marvellous numbers in November 

 with the like lateral range ; Nov. 11th, 12th, and 13th, an 

 almost continuous rush night and day, with S.E. winds and a 

 low pressure area in Western Europe.* Great Cotes, Nov. 26th, 

 first old cocks with yellow bills. Hasborough l.v., Jan. 19th 

 and 20th, 1885, easterly winds, Blackbirds all night. Farn l.h., 

 Jan. 6th to 19th, several on island. Longstone l.h., Jan. 4th, 

 N., rain, passing to land. Migration much in excess of previous 

 reports. Heligoland, first, Oct. 11th, and at intervals to Nov. 

 5th, up to which date no old cock had been seen ; last on 

 Nov. 10th and 12th. The migration of this species at Heligo- 

 land is very light compared with the English coast. 



T. torqaatus, Ring Ouzel. — Spring, 1884: -Farn Islands, 

 March 23rd to 29th, a few. Autumn : first seen, Sept. 9th, 



* This rush appears to have, in a greater or less degree, covered the 

 whole of the east coast. At the Longstone l.h., Farn Islands, it is 

 recorded by our observer, Mr. T. 0. Hall, as follows: — "Nov. 10th, all 

 kinds of small birds coming all day, one Snipe seen, wind southerly, hazy 

 weather; at 8 a.m., three grey crows to E. 11th, birds still coming, all 

 kinds, or rather the small kind, two Snipe, and one Woodcock. 12th, great 

 rush of Blackbirds, Ouzel, a few Mistletoe Thrushes., Redwings, Lapwings, 

 Grey and Golden Plover, as well as Woodcock and Snipe. This is the 

 greatest rush of the season, and lasted all day up to 10 p.m. ; complete 

 absence of Starlings ; wind all day from S. to S. by W., after midnight 

 changing to N.W." There was no corresponding rush across Heligoland 

 during the same period.
