80 RESIDENTS AND MIGRANTS. 



STOEM PETEEL. Procellaria pelagica (Linnaeus). 



Breeds in the Channel and Scilly Islands; on 

 Lundy Island, Ailsa Craig, lona, Staffa, and Tresh- 

 nish ; in Skye, and in all three groups of the Western 

 and Northern Isles. Mr. J. H. Gurney writes me 

 word that he is informed that it breeds on small 

 islands off the coast of Pembrokeshire. 



LEACH'S PETEEL. Procellaria leachii (Temminck). 



Breeds at St. Kilda in the Outer Hebrides (where 

 it was first noticed as a British bird by the late 

 Mr. Bullock in 1818), and in the Isle of Eum. Capt. 

 Elwes found it frequenting also the Isle of Mingalay, 

 where, in limited numbers, it breeds in holes and 

 cracks in the dry peat on the top of the cliffs. 



It is described by Mr. E. Gray as " strictly a west- 

 ern species in Scotland ;" and two instances only of its 

 occurrence on the east coast are recorded by him. 

 In Ireland it has been repeatedly obtained in autumn 

 and winter ; and, according to Mr. Thompson, it was 

 accurately described as breeding, in 1833, on rocky 

 islets near Sline Head, Galway. 



On the English coasts it is not uncommon in the 

 fall of the year, at which season, after a prevalence 

 of north-westerly gales, it is sometimes met with at 

 a considerable distance from the sea.
