192 THE ZOOLOGIST. 



large numbers are recorded ; in October another rush between 

 7th and 18th; on the former date numbers migrated with Larks 

 and other species not known, and many were killed and fell into 

 the sea at Skervuile. At Skerryvore one seen at 7 p.m. ; wind S., 

 fresh, with fog and rain. In September I have records on six 

 daj's at four stations; in October two at two stations, and in 

 December one at one station — Rlmvaal ; they passed or struck 

 mostly at night or morning, but a few through the day ; winds 

 mostly southerly, and hazy or foggy ; a few in cloudy and clear. 



Hedgesparrow. — At M'Arthur's Head, on Sept. 28th, one 

 struck at 1 a.m. ; wind N.W., strong, with haze and rain. 



Wheatear. — Wheatears or " Stonechecks" are recorded from 

 Skerryvore as the most northerly station this year, and thence 

 southward at Rhuvaal, Skervuile, Turnberr}-, Corsewall, and 

 Mull of Galloway. The earliest appearance noted is on Aug. 

 loth, and the latest on Sept. 28th; thus the migration extended 

 over forty-four days. The greatest rush was between Aug. 17th 

 and 22nd. The migration took place entirely at night, and 

 principally with southerly winds — S., S.W., and to W. ; fewer in 

 northerly or easterly winds. The favoured stations were Skerry- 

 vore, Rhuvaal, and Skervuile. 



Titmice. — ^The negative information that Mr. Edgar never 

 saw any Titmice at the Butt of Lewis lighthouse is worthy of 

 record. I have notes of their occurrence at M'Arthur's Head and 

 Lamlash ; in each case a single bird struck the lantern, Nov. 16th 

 and Aug. 17th, at 6 p.m. and 10 a.m. respectively; both during 

 west wind, and light air. 



Fieldfare. — Occurred at Monach Island and Douglas Head, 

 and is reported as usually seen at Butt of Lewis, though not this 

 year. At Monach Island a number struck, and fifteen were 

 killed, between 8 p.m. and 4 a.m., on Oct. 21st and 22nd ; wind 

 S.W., fresh, and drizzling rain. At Douglas Head one was 

 seen on Oct. 16th, at 10 a.m.; wind N., moderate breeze, and 

 cloudy. 



Thrush. — The most northern station is, for 1879, Isle 

 Ornsay. Mr. Edgar; however, adds the general information that in 

 most years the Butt of Lewis yields large numbers at the lantern ; 

 thence southward at Skerryvore, Dhuheartach, Rhinns of Isla3% 

 Lochindaul, Lamlash, Corsewall, and Point of Ayre. The 

 earliest date is Sept. 19tli, when a mixed flock of Thrushes and
