Common Cormorant, Phalacrocorax carlo ; generally distributed 

 throughout the western coast of Cornwall. 



Common Shag, P. cristatus ; more numerous as a species than

 arms of the sea. 



Grannet, Sula hassana; not unfrequently observed, and sometimes 

 in small companies, in Mount' s-bay and on the north coast. 



Sandwich Tern, 8. cantiaca ; a few pairs observed in the summer 

 months on some of the islands at Scilly. 



Roseate Tern, S. DougalUi ; formerly abundant in summer at 

 Scilly : breeds on Annet, a Scilly rock, and some other 

 localities near. 



Common Tern, 8. Mrundo ; more or less common in the summer 

 in Mount' s-bay, approaching nearer the shore in windy 

 weather : less abundant at Scilly than the roseate or 

 arctic terns. 



Arctic Tern, 8. Arctica ; a common species in summer both on 

 our coast and at Scilly, at which latter locality its eggs may 

 be obtained every year. 



Whiskered Tern, 8. leucopareia ; an immature specimen obtained 

 in the month of September, 1851, at Scilly.

 captured in England. In the latter part of May or begin-

 winter in its immature plumage. This bird has been mis- 

 taken for the little gull, but in its young state it may be 

 known by the absence of black in the wing, by the greater 

 length and slenderness of the beak, and by the tail being 

 deej)ly forked.
