The Distribution of Birds in Great Britain. 467 



Mr. J. H. Dunn marks the Fork -tailed Petrel as having formerly 

 nested in Orkney ; but the bird is not mentioned in the ' Fauna Orca- 

 densis,' 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.
