WARBLERS 359 



Obs. Found breeding in Siberia by Seebohm in 

 the forest between the Yenesei and the Koorayika. 

 The nest on the ground in a tuft of grass, semi- 

 domed, composed of dry grass and moss, lined with 

 reindeer hair ; eggs resembling those of the Willow- 

 Warbler. This is the Dalmatian Regulus of some 

 authors ; a singularly inappropriate name, since the 

 bird is not a Regulus, and is as rare in Dalmatia 

 as it is in Great Britain. It is the Yellow-browed 

 Warbler of Pennant and Latham, by whom it was 

 first made known.

Ifah. Siberia, the Himalayas, and North China; but 

 occurring annually on the western slopes of the Ural, and 

 having been once obtained on Heligoland.

 Proc. Zool. Soc, 1896, p. 856, and Trans. Norf. Nat. 

 Soc, 1897, p. 280, with coloured plate ; Southwell, 

 ZooL, 1896, p. 466, 1897, p. 8 ; and Gurney, figure, Zool.,

Obs. Distinguishable from the Yellow-browed 

 Warbler, P. siL2}erciliosus, by having a yellowish 

 stripe along the centre of the crown to the nape ; 

 the rump and two wing bars lemon-yellow. 



From the observations of the late Mr. Cordeaux 

 it would appear that the Siberian Willow Warbler, 

 Phylloscopus borealis, "with a very distinct wing 

 bar," has occurred in this country at least once, viz.,
