326 STUDIES IN BIRD-MIGRATION 



under our notice. One was seen at sea between Le 

 Conquet and Mol^ne on gth September. 



Alderney. — A few seen daily on the coast up to 28th 

 September, the day of our departure. 



ToTANUs CALiDRis, Redshank. 



Ushant. — The island offered few inducements to the

 tarry on the island in such numbers. 



Sterna macrura, Arctic Tern. 



Ushant. — Terns were abundant off the island during 

 our visit ; but it was not until 14th September that we 

 identified Sterna macrura. On that day we watched 

 a number of Arctic terns as they rested on a rock 

 just off the south coast of the island. Among these 

 we detected no fewer than ten individuals in that 

 stage of adolescent plumage which led Mr Ridgway 

 to describe this bird as a distinct species under the 

 name of Sterna portlandica. There was no doubt as 

 to their identity, for, as if to oblige us, some of 

 them continually left the rock and alighted on the 

 shore just at our feet. We may, I think, fairly
