512 Herr E. Hartert on the 



moors. At present it is, so far as I could make out, only 

 met with on the great moor in the district of Dingken, and 

 in small numbers. This is the only place in Germany where 

 it occurs. 



COTURNIX COTURNIX (L.). 



Not numerous in East Prussia. 



Perdix perdix (L.). 



Common, but suffers much from severe winters. 



Ardea garzetta, L. 



Two specimens were killed many years ago near Pillau. 

 They are preserved in the Konigsberg Museum. 



Ardea purpurea, L. 



I think Bock's ''Ardea violacea vel Ardea I'ubra " ('Natur- 

 forscher,' 1778) is referable to this species. It may occur 

 as an accidental straggler. 



Ardea cinerea, L. 



Common, breeding in large colonies, but occasionally in 

 single pairs. 



ArDEOLA RALLOIDES (Scop.). 



May accidentally occur, as it has been killed in West 

 Prussia. 



Ardetta minuta (L.). 



I have only met with this bird a few times, but it seems to 

 be much less rare than I once believed it to be. 



Nycticorax nycticorax (L.). 



Bock states (' Naturforscher,' 1778) that the Night Heron 

 breeds in Prussia. He received specimens on the 18th of 

 May, 1849. I shot a young bird in the first plumage on 

 the 30th of August, 1880, near Pillau. 



BOTAURUS STELLARIS (L.). 



Common during migration, but also found breeding in 

 many localities. I have taken eggs in the middle of May. 



CiCONIA CICONIA (L.). 

 Common and breeding.
