Birds of East Prussia. 365 



of this form, as given by Mr. SeeboLra, is Pomerania, the 

 Baltic Provinces of Russia, Poland, and the Crimea. As 

 regards Pomerania this is not correct. Homeyer's collection 

 contains specimens of it from East Prussia only ; those 

 from Pomerania belong to the true western Sitta ccesia. The 

 mistake probably arose from my giving the localities on the 

 labels too exactly, quoting small places- not known abroad, 

 instead of better-known and more general terms. 



Regulus regulus (L.). 



The Golden-crested Wren is very common during the 

 winter, but only a small number remain in the forests to 

 breed. 



(I never met with Regulus ignicapillus, nor do I know of 

 a verified occurrence of this bird in East Prussia.) 



Ceethia familiaris, L. 



Common throughout the year. Only the true C. familiaris, 

 with a pure white breast, occurs. 



MOTACILLA ALBA, L. 



Very common. The weather in East Prussia is too severe 

 to allow them to remain during the winter. 



MOTACILLA FLAVA, L. 



Very common. 



(The statements that " M. sulphur ea " and '^ M. citreola " 

 are met with in the breeding-season are best passed over 

 in silence. 



Probably Motacilla borealis will be found on passage, but 

 I never saw it.) 



Anthus pratensis (L.). 



March to Qctober. Breeds in many suitable localities. 



Anthus trivialis (L.) { = arboreus). 

 Common from April to September. 



Anthus campestris (L.). 



Although the many sandy desert-like tracts would be 

 suitable localities for this Pipit, it is rather rare. I met
