but of small dimensions. Larks appear to migrate principally 

 when the wind is W. to S.W., or late in the season, when still 

 more soutlierl}', say S. Exceptions occur at Dhuheartach on 

 Nov. 24, when wind was N.E., fresh, and weather clear; at 

 Rhinns of Islay on Nov. 7th, wind N.W., light breeze ; at 

 Skervuile on Oct. 10th, when wind was N. ; they migrate in calm, 

 variable, light, or fresh winds, and are noticed at lanterns 

 principally in haze and fog. They migrate mostly at night, at 

 all hours, but the majorit}^ pass between 7.30 p.m. and 4 a.m. 

 Those passing during the day were travelling when the wind was 

 N. or N.E.; those passing at night when the wind was S. to W. 

 So the returns show; but whether this indicates any law of 

 migration or not remains to be proved by further observation. 



LArwixG. — The most northern station which they were 

 observed to pass at this season was Rhu Stoir ; thence south- 

 ward, they are reported at Isle Ornsay, Lochindaul, Devaar, 

 Pladda, and Portpatrick. The earliest date given is Aug. aoth, 

 when "flocks" were seen during the day in N. wind and clear 

 weather; the latest is Dec. 11th, when one was killed at Pladda, 

 at 2 a.m., wind S.E., light breeze, with haze. The next latest 

 date given is Nov. 14th, when twenty-two were seen at 8.30 a.m. 

 at Portpatrick, wind S.E., and haze. The time occupied, therefore, 

 this year is from eightj^-six to one hundred and thirteen days. 

 Rushes took place about the 20th to 25th August, when several 

 flocks passed Isle Ornsay and Lochindaul ; again, Sept. 16th to 

 25th, a flock at Devaar, Portpatrick and Chickens Rock ; another 

 rush at Rhu Stoir, Portpatrick and Lochindaill about Oct. 2*7 th. 

 Lapwings travelled in clear or haze, rain, or showers, principally 

 in S. and S.E. winds, on the west coast; but also in N. wind on 

 Aug. 20th, and in W. and S.W. at Rhu Stoir and Lochindaul on 

 Oct. 23rd and Nov. 1st respectivel3^ They appear to travel 

 equally by day and night. 



Plover. — Three stations give returns of this species, viz., 

 Skerryvore, Rhinns of Isla}-, and Portpatrick. The earliest date 

 is July 27th, at Portpatrick. The latest date is Oct. 18th, at 

 Skerryvore. The time thus occupied b}^ the migration was fifty- 

 three days. The principal rush took place about the beginning • 

 of September, and tlie favoured station was Portpatrick, where 

 they were always observed prssing inland with a S. to S.W. wind, 

 light or strong breeze, during the daytime. Individuals struck
