Lilford, ‘Coloured Figures,’ vol. vi, pl. 57. 
The Frigate-Petrel, a native of the Oceans of the 
Southern Hemisphere, has twice been procured off the 
British coast; once in England and once in Scotland, on 
both occasions after heavy gales. The first record is that 
of a bird washed ashore dead on Walney Island off the Lan- 
cashire coast in November, 1890. It was identified by the 
late Mr. O. Salvin, who obtained it from the late Rev. H. A. 
Macpherson (‘ Ibis,’ 1892, pp. 602-604, vide also ‘ Fauna of 
Lakeland,’ p. 457). The other example was taken alive on 
the Island of Colonsay on January Ist, 1897, and was 
identified by Mr. Eagle Clarke ; it is now preserved in the 
Edinburgh Museum (Ann. Scot. Nat. Hist., 1897, p. 88).
