MANX SHEARWATER 
259 
PROCELLARIA LEUCORRHOA (Vieillot). 
LEACH'S FORK-TAILED PETREL. 
In the Migration Eeport for 1887 Messrs. Black and Beggs 
report from the Chickens, under date of 21st November 1887, 
1 One Fork-tailed Petrel flying about the rock at 7.30 A.M.' 
Heavy storms have from time to time strewn the species 
broadcast over Ireland, and it has similarly occurred around 
the Irish Sea, usually in the autumn months. It breeds in 
several of the Outer Hebrides. 
PUFFINUS ANGLORUM (Temminck). 
MANX SHEARWATER. 
Puffin, Manx Puffin. 
Willughby described the Shearwater (Ornithologia, 1676, 
p. 252; Ornithology , 1678, p. 334) from a young specimen 
taken from the nest, and almost certainly Manx, as is 
shown by the detailed description of the Calf of Man, and 
the habits of the birds nesting there. Ray saw later, in 
Tradescant's Museum and that of the Royal Society, other 
specimens, which he assigns to the same species, but this 
must remain uncertain. In the catalogue of the Eoyal 
Society's Museum, printed in 1681 and compiled by 
N. Grew, no mention of Puffinus anglorum is found, but an 
entry under ' Puffin, Anas arctica : They breed in Island, in 
the Isle of Mona, in Scotland, in those of Fero and the 
Syllies ; also in Ireland, and other places/ 1 In the Museum 
1 I have to thank Messrs. Harrison and White for searching on my behalf the 
archives of this Society ; also Professor Newton for much kind correspondence, in 
which he has fnlly discussed the subject with me. It is to be feared that no 
further light is now to be obtained on the subject, and the discrepancy with 
Ray's statement is difficult to explain.
