2 Mr. H, Saunders on the Occurrence of 



in these districts, but notliiug is known of its nidification. 

 The most detailed account of this Warbler is by Godlewski, 

 who writes to the following effect : — On its migrations this 

 species is common throughout South-eastern Siberia and in 

 Daiiria, and is widely distributed in autumn ; but it is rarer 

 in Ussuria, though it appears to nest there, for it sings all 

 through the summer. In the early part of August, during 

 our journey across the Government of Yeniseisk, on the 

 road between Irkutsk and Tomsk, it was also singing, so 

 that it pi'obably nests there. On passage it frequents the 

 bushy margins of the forests, and it arrives early in June. Its 

 song is short and not very agreeable, but loud, and the alarm- 

 note may be rendered as gibout-giboid. We did not find its 

 nest. It leaves Ussuria about the middle of September. 



In winter Radde's Bush- Warbler visits Southern China, 

 Pegu, and the northern and central portions of Tenasserim 

 (Gates, Fauna Brit. India, Birds, i. pp. 399-400). Its large 

 bastard-primary indicates its connection with the genus Lus- 

 ciniola, in which Seebohm placed it ; but Mr. Gates finds this 

 genus too comprehensive, and relegates the bird to the genus 

 Herbivocula of Swiuhoe. The upper plumage is olive-brown, 

 tinged with tawny, especially on the rump ; wings and tail 

 brown, edged on the outer webs with the colour of the back; 

 supercilium very distinct and reaching to the nape ; lores and 

 feathers behind the eye dark brown ; ear-coverts buff and 

 brown ; lower plumage rich tawny buff, paling on the throat 

 and abdomen ; axillaries and under wing-coverts buff. In 

 summer the lower parts are nearly white, merely tinged with 

 yellow or buff, more especially so on the vent and under 

 tail-coverts. Bill horn-colour, the base fleshy white and the 

 gape yellow ; iris brown ; legs and feet fleshy yellow. Length 

 about 5-6 inches, wing 2'45, tarsus 0-9 inch, bill from gape 

 0'65. The 2nd primary is equal to the 8th, or intermediate 

 between the 7th and 8th ; the 1st primary is very long, 

 measuring 085 inch in length (Gates). 



The young bird, like ]\lr. Haigh^s specimen from which 

 the figure (Plate I.) is taken, is decidedly more olivaceous 

 on the upper parts. The bill is stout and deep for a
