FULIGULA NYROCA (GiilcT.) . 



Not uncommon in summer. Eggs to be found iu the 

 middle of May. 



FULIGULA RUFINA (Pall.). 



A male and a female in the Konigsberg Museum are 

 stated to have been killed in the province. 



Clangula glaucion (L.). 



In immense numbers frequenting the sea-coast and the 

 HafFs during the winter. 



Heniconetta stelleri (Pall.). 



This beautiful Duck was not very rare some time ago, 

 especially from 1840 to 1850, and many were shot near Pillau 

 and some near Danzig, but only on the sea. I have not 

 been able to ascertain its occurrence within the last 25 years. 



Somateria mollissima (L.). 



A few may be observed every winter. An adult female 

 was shot in August 1887 near Pillau. 



ffiuEMIA NIGRA (L,). 



CEdemia fusca (L.). 



Both these species are not rare on the sea and the Haffs 

 during the winter ; the latter is somewhat the more common. 



MeRGUS MERGANSER, L. 



This species is found in East Prussia during the winter, 

 and breeds plentifully in the southern and eastern parts. 

 The eggs are deposited in large hollow trees, and are laid 

 from the end of April until the middle of May. 



Mergus serrator, L. 



This species, too, breeds in East Prussia, but is not so 

 numerous as the last-mentioned. The eggs are deposited on 

 the grassy islands, not in hollow trees. 



Mergus albellus, L. 



Not rare during the winter until April. 



Pelecanus onocrotalus, L. 



A specimen, of which a picture is iu the Museum of Konigs- 

 berg, was killed near Johannisburg in 1608.
