 were so dark in colour would, however, appear rather to

 long mistaken for the young of P. major.

 in his " Birds of the West of Scotland," mentions Eigg as 

 one of the islands from which he had obtained specimens of 

 this Petrel. 



84. Thalassidroma ])elagica (Storm Petrel). — In the same 

 work it is stated that a colony of this species has long existed 

 on Eigg. The author informs me that he obtained most of 

 of his Eigg records from the late Dr Dewar of Glasgow.

 Harvie-Brown was under the necessity of leaving home for a 

 few weeks, he was unable personally to follow up his dis-

 specimen of the Greater Shearwater on the coast of Skye in July 1885.
