362 Herr E. Hartert on the 



rather contemptuously^ but in myopinion^when larger material 

 of A. palustris and A. streperus and their allies from different 

 localities has been collected and studied over again, the result 

 will probably be the discovery of several subspecies or even 

 species. At least I believe that there is one form distinct 

 from both the Marsh Warbler and the small Reed Warbler, 

 which seems to stand somewhat between these two common 

 species. Probably Brehm's subspecies, A. arbustorum and 

 A. pinetorum, as well as Naumann's A. horticola and A.fruti- 

 cola, are all referable to this one form, which is an inhabitant 

 of swamps rather than of gardens. At present I am not able 

 to make this out for certain, but I wish to call the attention 

 of those who may be in possession of sufficient material to this 

 group of species. 



Sylvia atricapilla (L.). 

 Very common. 



Sylvia hortensis, Bechst. 



Not rare, but far less numerous than S. atricapilla. 



Sylvia SYLVIA (L.) { = cinerea). 

 Very common. 



Sylvia nisoria (Bechst.). 



This species is very common all over the province in suit- 

 able localities. The eggs are laid in the last part of May 

 and the beginning of June. Once I found a clutch with all 

 the eggs spotted with deep chestnut-brown. 



Sylvia curruca (L.). 



Not rare, but less common than in Silesia and Western 

 Germany. 



Accentor modularis (L.). 



This bird is very rare, probably not breeding, and only a 

 straggler. I have seen only one specimen, that had been 

 shot during very unusual and severe weather in spring. It 

 has been lately recorded as occurring near Norkitten 

 [Robitzsch). 



Anorthura troglodytes (L.). 

 Common at all seasons.
