their arrival on the headland, and has known them killed 

 by flying against the hght in thick, foggy weather, with the 

 wind E.N.E. He has also seen them on their departure 

 in September, and has noticed several in October and 

 November. Inland, it is extremely rare, being recorded as 

 observed near Leeds (several times, two or three in 1843), 

 and once near Bingley. 



Sab-fam. SYLVIINM. 



18. Cyanecula wolfi C. L. Brehm. White-spotted Blue- 



throat. 



Accidental visitant from Central and Western Europe, of 

 extremely rare occurrence. 



Near Scarborough, a female picked up dead beneath the 

 telegraph wires, about the 9th of April, 1876 (Tuck, Zool., 

 1876, p. 4956). 



19. Cyanecula suecica (Z.). Red-spotted Bluethroat. 



'20. Erithacus nubecula (Z.). Redbreast. 



Resident, generally distributed, abundant. Immigrants are 

 observed on the coast in the autumn, often in large num- 

 bers, returning early in March. 



21. Daulias luscinia (Z.). Nightingale. 



Summer visitant, of regular occurrence in very limited num- 

 bers in the neighbourhood of Barnsley, Wakefield, York, 

 Beverley, Patrington, Brough, Selby, and Doncaster, 

 arriving early in May. West and north of the frontier 

 formed by these towns it is only of exceptional occurrence, 

 and a line drawn from Huddersfield, through Bradford, 

 Otley, and Ripon, to Baldersby, Bagby, and Sessay, near 

 Thirsk, and thence to Flamborough Head, will include all 

 the localities for which there is satisfactory evidence of its 

 ever having occurred or bred, and also defines the extreme 

 northern limit of its distribution in Britain. 



The Hon. F. H. Dawnay informs me that a pair passed 

 the summer of 1868 at Baldersby Park, in 1876 it occurred 

 at Sessay, and this year (1881) I am told by Mr. Robert 

 Lee that it has appeared at Bagby — all near Thirsk. In 

 1876 it nested at Little Thorp, near Bridhngton, an &gg 

 being sent for my inspection by Mr. W. F. Foster. There 

 is also reliable evidence of its occurrence in other localities,
