and rare inhabitant of the outskirts of forests and smaller 

 woods, and only in winter comes into the gardens. It is_, 

 however, not a distinct form, specimens agreeing with those 

 of other countries. 



(TURDUS ATRIGULARIS. 



May occur occasionally as a rare visitor, as it has been 

 found twice near Elbing and Danzig.) 



Phylloscopus rufus (Bechst.). 



Arrives first of its congeners, and breeds first, but regu- 

 larly rears a second brood. Passes through in great num- 

 bers until October. 



Phylloscopus trochilus (L.). 



Almost equally common with P. rufus. Arrives a little

Hypolais hypolais (L.).

Not rare in the northern and north-eastern parts. Its

 best in morning and evening, but also often in the middle of 

 the day. In autumn it is found during migration in low 

 bushes and in potato-fields or amongst other low crops. 



LoCUSTELLA FLUVIATILIS (Wolf). 



Has been shot at Ibenhorst, near the Kurische Hafi^, where 

 it seems to be not very rare in summer. Although I often 

 heard its song when a boy in Silesia, I did not meet with 

 this bird elsewhere in East Prussia. Recently, however, it 

 has been obtained on the Kurische Nehrung and near Pillau 

 by Herr Lindner. The song of L. fluviatilis (which Herr 

 von Middendorff, I, and other members of the Congress at 

 Budapest heard in the swampy forests near the Hansag, in
