Begulus proregidns, Pall. I met with this species from Orenburg 

 Province as far as BogoslafFsk, and even in the birch woods of the 

 eastern slopes. 



Ficedula hijpolais, (Bechst.) Is distributed through the Govern- 

 ment as far as BogoslafFsk, and is commoner in the Ural than in 

 the Bashkir woods. 



FicecMa rtifa, (Lath.) Its distribution is similar to that of the 

 preceding species, and it also appears to be commoner on the 

 western slope than on the eastern. According to Nordmann 

 (op. cit., p. 27), Ficedula hypolais becomes commoner in Finland 

 every year. Lilljeborg {op. cit., p. 95) met with it about as far 

 north as Cholmogory. It is strange that MejakofF should call it a 

 rare and late visitor {op. cit, p. 630). 



Ficedida trochilus, (L.) Is very common everywhere, although 

 not so numerous as in Central Russia. 



Sylvia curruca, Lath. We met with it in all the localities visited 

 by us. 



Sylvia atricapilla, (L.) In the Ural and in the conifer woods 

 it is commoner than in the birch woods of the Bashkir country. 

 We did not observe it north of Ekaterinburg. According to 

 Nordmann, the present species (and Sylvia nisoria) occasionally 

 visit the southern parts of Finland ; and Lilljeborg says that 

 S. hortensis, cinerea, and curruca occur near Archangel (op. cit.) 



Sylvia cinerea, Briss. Its range extends probably as far north 

 as Bogoslaffsk. Teplouhoff found it at the river Obva, in 

 58 J° N. lat. It is commoner than ^S'. curruca, but not so numerous 

 as that bird is in Central Russia. 



Sylvia Jiortensis, Bechst, It has been observed as high as 

 59*^ N. lat., and is tolerably common. 



Sylvia cyanura, Pall. We came across this species in the 

 thickest forests of Tagila and the Pavdinsky Dacha, and found it 

 there rather common, so that it probably goes further south in 

 the Ural, and even visits the western slope. 



Sijlvia nisoria, Bechst. I did not see it myself, but Martin ob- 

 served it at the Keshtemsky works, and it is very likely that it goes 

 north as far as 57" N. lat. ; but as these birds inhabit the thick 

 bushes, and lead a very retired life, they are not easily detected. 



Lusciola iMlomela, (Bechst.) Scarce on the south-east slope of 

 the Ural, but occurs also in the mountains themselves. 

 Occasionally it appears in the neighbourhood of Ekaterinburg, and
