FORK-TAILED OR LEACH'S PETREL. 285 



for the Gulls. On November Srd, 1859, an example in very- 

 perfect plumage, but minus a foot, lost apparently long ago, 

 was picked up dead on Patches Farm, Cowfold ; this also was 

 after a furious gale, and at least ten miles from the sea. 



Mr. Knox mentions its occurrence in many places along 

 the coast, and specially notices one picked up at Lodsworth, 

 almost fifteen miles inland. Mr. Jeffery (p. n.) mentions 

 one found dead at Sidlesham, November 25th, 1865, and 

 two others, on the 28th of the same month, at the same 

 place ; also one shot at Bosham on December 5th, 1866, 

 which was found to contain pieces of sea- weed, and parts of 

 the stems and blossoms of sainfoin, and two more obtained 

 in November and December 1881, one at Dell Quay, the 

 other at Birdham. Mr. Dennis informed me that a Fork- 

 tailed Petrel was found alive among the furze at Denton Top, 

 near Lewes, December 15th, 1856. 



In the 'Zoologist' (p. 2392) one was recorded by me 

 which was picked up alive, but ia an exhausted state, at Eot- 

 tingdean, on December 14th, 1849, and Mr. Ellman records 

 another example which was found dead on the shore at 

 Brighton, on November 8th, 1850 (p. 2970). 



This Petrel breeds on St. Kilda, and on North Rona, 

 where Mr. Swinburne found it abundant, nesting among 

 some old ruins, one large main burrow serving for several 

 pairs of these birds, which made smaller burrows branching 

 off from it at right angles. The note is said to resemble the 

 syllables, " pewrit-pewrit." It feeds, like the other, on any 

 greasy substances it can obtain. 



In Messrs. Harvie-Brown and Buckley's 'Fauna of the 

 Outer Hebrides,' we find, at p. 154, that Sir W. E. Milner 

 discovered a colony of these birds on the Dune of St. Kilda 

 in 1848, He considered that they bred three weeks earlier 

 than the Storm Petrel. And since his visit there this 

 species has been found in great abundance on Borreay, one of
