84. Mr. A. G. More on the Distribution of Birds, &c. 
Purrinus ANGLoRuM (Boie). Manx Shearwater. — 
Provinces I. [XII.] XVI. XVIII. 
Subprovinces 1, 2, (25), 33, 36-38. 
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 abundant on the Calf of Man, where Mr. Crellin considers 
that it was extirpated by rats. Mr. H. D. Graham finds it breed- 
mg on the Islands of Staffa and Treshnish; and there are seve- 
ral 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. 
THALASSIDROMA LEACHI (Keys. & Bl.). Fork-tailed Petrel. 
Province XVIII. 
Subprovinces 36, (37) ? 
Lat. 57°-58° or 59°. “Atlantic” type. Not in Ireland. 
The only breeding-station known with certainty is St. Kilda, 
in the Outer Hebrides. 
Mr. J. H. Dunn marks the Fork-tailed Petrel as having for- 
merly nested in Orkney; but the bird is not mentioned in the 
‘Fauna Orcadensis,’ nor in the more recent work of Messrs. Baikie 
and Heddle. Mr. Dunbar includes it in his ‘ List of the Birds 
of Ross-shire,’ but without mention of the locality. 
THALASSIDROMA PELAGICA (Vigors). Stormy Petrel. 
Provinces I. XIII. XVI. XVIII. 
Subprovinees 1, 2, 27, 33, 36-38. 
Tat. 49°-61°. “Atlantic” type, or Western. 
In the Scilly Isles. In Lundy Island (Rev. M. A. Mathews). 
On Ailsa (Mr. R. Gray). On Iona, Staffa, and Treshnish (Mr. 
R. D. Graham). In Skye (Mr. J. Macgillivray, fide Yarrell) ; 
and in all three groups of the Western and Northern Isles. 
Sir W. Jardine has seen small parties of Stormy Petrels, in 
June, off the Isle of Man, where they probably breed.
