COLYMBUS SEPTENTRIONALIS^ L. 



Commou on the sea in winter. 



CoLYMBUS ARCTICUS (L.). 



This species is not rare in winter. Several adult speci- 

 mens have been seen and procured in summer during the 

 breeding-time, and therefore it seems very probable that 

 this species occasionally nests within the limits of North- 

 eastern Germany. Bock (1778) says that " Anser colymbus" 

 has been caught near Friedrichstein in June ; he, no doubt, 

 refers to the present species. It has been observed several 

 times on lakes in Pomerania, and I shot an adult female 

 on the 29th July on the Frisehe Haff, which had laid eggs 

 not long before, to judge from the dissection. 



Mergulus alle (L.). 



Has been shot a few times on the sea, but is a great rarity 

 for East Prussia. 



Uria grylle (L.). 



A regular but not common winter visitor along the coast. 



Uria lomvia (L., 1758). 

 Uria troile, L. 



Has been shot near Danzig, but not, so far as I know, on 

 the East Prussian coast. 



Alga torda, L. 



Not very rare in winter on the Baltic Sea and on the 

 Haffs.

(Plate XIII.) 



When preparing the Catalogue of the Birds of the 

 Senckenberg Museum at Frankfurt-a.-M., I found in the 

 Collection a stuffed specimen of a Lark, no doubt belonging 

 to the genus Otocorys. As it was of an entirely unknown
