Mr. Shearer is perfectly aware of the difference between the Long-tailed 

 and Arctic Skuas, and that he has always been accustomed to distinguish 

 the two species. 



Mr. Robert Gray, of Glasgow, who has paid much attention to the 

 birds of the West of Scotland, tells me that he has seen a pair of the 

 Long-tailed Skua, male and female, which were obtained, in June, 

 1862, on the Island of Wiay, off Benbecula, one of the Outer Hebrides. 

 These birds were shot above a marsh where the Arctic Skua was breed- 

 ing ; so that there can be little doubt that they had a nest. 



Mr. J. H. Dunn tells me that three pairs of the Long-tailed Skua 

 bred in Hoy Island in 1852, when he obtained their eggs. None have 

 nested since. 



PROCELLARIA GLACIALIS (Linn.}. Fulmar.

Subprovince 36. 



Lat. 57-58. " Scottish " type. Not in Ireland. 



Only in the Outer Hebrides, where St. Kilda has long been noted 

 as the principal breeding -place. Yarrell adds the neighbouring- 

 islands of Borrera and Soa, on the authority of Mr. G. C. Atkinson, 

 "who was informed that the birds also breed in the South Isles of 

 Barra." 



PUFFINUS ANGLORUM (Boie). Manx Shearwater.

Lat. 49-61. "Atlantic " type, or western. 



The Manx Shearwater breeds in the Scilly Islands. In Lundy Island, 

 in the Bristol Channel (Rev. M. A. Mathews}. Formerly it was abun- 

 dant on the Calf of Man, where Mr. Crellin considers that it was extir- 

 pated by rats. Mr. H. D. Graham finds it breeding on the Islands of 

 Staffa and Treshnish ; and there are several localities in the Outer 

 Hebrides, Orkney, and Shetland. 



It will be observed that all these localities are situated on the west 

 coast, and the nest seems always to be placed upon islands. I am not 

 aware of any breeding- station on the mainland, unless Berwickshire 

 should prove to be an exception, as the Rev. J. Duns tells me that he 

 has seen it during summer off St. Abb's Head, and believes that a few 

 pairs breed there occasionally.

The only breeding-station known with certainty is St. Kilda, in the 

 Outer Hebrides.
