1879.] ON BIRDS FROM DUKE-OF-YORK ISLAND. 9 



lopement of the entire plumage. The bird avoided the water for a 

 few days l)efore it began to moult, and also after it had renewed its 

 feathers ; it soon, however, became lively, its eyes assumed their usual 

 form and brightness, it took freely to the water, in which it passed 

 the greater part of the day. Its movements in the water when 

 swimming, diving, and pursuing fish were most extraordinary; it 

 seemed, as it were, to fly under water, using its flipper-like wings 

 after the fashion of a Seal. 



The Penguin appears so much at home in the water, so perfectly 

 adapted to an aquatic life, that one would conclude that, but for the 

 necessity of breeding and moulting, this bird would be far more at 

 home on the ocean than in passing even a sborl period on land, being 

 so ill-ada^ited in form for travelling on shore.

 York Island and New Britain. By Otto FinscHj Ph.D.

[Eeceived November 20, 1878.] 



From the Museum Godeffroy at Hamburg I have received a col- 

 lection of the birds of Duke-of-York Island and the adjoining parts 

 of New Britain, sent over by Mr. Hiibner. Although through the 

 zealous efforts of the Rev. George Brown, we are pretty well 

 acquainted with the fauna of Duke-of-York Island, especially with 

 its ornithology, on which Dr. Sclater has published some valuable 

 papers, I think the following paper will forma not uninteresting con- 

 tribution to our knowledge. 



Tlie present collection contains 52 species from Duke-of-York 

 Island, and 7 from New Britain, 14 being new to the former group, 

 namely Hahaetus leueogaster, Hirundo javanica, Cuculus canorus, 

 Scythrops novce-hoUanduB, Macropygia doreya, Strepsilas interpres, 

 Esacvs magnirostris. Sterna hergii, St. longipennis, Procellaria 

 neglecta, Pr. leucoptera, Pvffinus leucomelas, P. tenuirostris, and 

 Dysporus sula. 



Except the native names, Mr. Hiibner has given me no notices ; I 

 therefore can only copy these, reminding you that the pronunciation 

 of them is according to the German language.
