452 THE ZOOLOGIST. 
Migration read at the last meeting of the British Association, 
and by the distribution of this Report to the various lightship 
and lighthouse stations in England and Scotland. We have 
to thank the Trinity House for the liberal view they have taken 
of the work, and for relieving us of much expense in connection 
with it. : 
According to Mr. Agnew’s schedule, under date Sept. 17th, 
the wind was light westerly with haze. The next record occurs 
on the 22nd, the date of the capture of this specimen and of 
numerous arrivals of Redstarts, Mavises, Swallows, Golden Plover, 
Ring Dotterel, Lapwings, Chaffinches, one Corn Crake, one Robin, 
Curlews, &c.—indeed of a “rush” of migrants. On that day, and 
for some days previous, the wind was strong 8.E., and it continued 
so all day: “‘ weather, very thick haze, approaching to fog, with a 
continuous downpour of rain.” Mr. Agnew adds, “ All the birds 
seen to-day seemed perfectly bewildered.” 
The bird of which I now speak is Cyanecula Wolfi, or the 
white-spotted—sometimes spotless—form of the Blue-throated 
Warbler. The other form, Cyanecula suecica, or Red-spotted 
Bluethroat, is more northern in its range in Europe than the 
bird under consideration, and hitherto, with one exception, is 
the only species or form of the genus which has been recorded 
in Great Britain. Cyanecula Wolf is found over Central Europe, 
and breeds in Holland, Germany, and southward, and is found in 
winter in Spain, Italy, and the shores of the Mediterranean (vide 
Dresser’s ‘Birds of Europe,’ vol. i. p. 312), and according to 
Prof. Newton (Yarrell, 4th ed. vol. i. p. 824) has only once before 
occurred in Britain (vide Hadfield, Zool. 1866, p. 172, where the 
bird recorded as “ Blue-throated Warbler” belongs to this form). 
The specimen in my possession closely agrees with the bird figured 
in Dresser’s ‘ Birds of Europe’ (vol. i. pl. 50), of which he says 
(p. 820), ‘a male of C. Wolfi in rather peculiar autumn plumage.” 
I have now, therefore, to record the second occurrence of the 
white-spotted form (which two Dresser unites under Cyanecula 
Wolfi) in Britain, and its first occurrence in Scotland. 
Now, in connection with the distribution and rare occurrences 
of European or other species in Britain, I wish here to say a few 
words. In 1875, on the 10th November, I obtained a Black Red- 
start, Ruticilla titys, at Kineardine-on-Forth, which was duly 
recorded, and the specimen exhibited, at the Royal Physical
