Show 18/9.J ON BIRDS FROM DUKE-OF-YORK ISLAND. 9 lopement of the entire plumage. The bird avoided the water for a few days before 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 short period on land, being so ill-adapted in form for travelling on shore. 2. O n a Collection of Birds made by M r . Hiibner on Duke-of- York Island and N e w Britain. By O T T O F I N S C H , Ph.D. C.M.Z.S. [Received November 20, 1878.] From the Museum Godeffroy at Hamburg I have received a collection of the birds of Duke-of-York Island and the adjoining parts of N e w 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 form a not uninteresting contribution to our knowledge. The present collection contains 52 species from Duke-of-York Island, and 7 from New Britain, 14 being new to the former group, namely Haliaetus leucogaster, Hirundo javanica, Cuculus canorus, Scythrops novce-hollandice, Macropygia doreya, Strepsilas interpres, Esacus magnirostris, Sterna bergii, St. longipennis, Procellaria neglecta, Pr. leucoptera, Puffinus leucomelas, P. tenuirostris, Dysporus sula. Except the native names, Mr. Hiibner has given m e no notices ; I therefore can only copy these, reminding you that the pronunciation of them is according to the German language.
