Obs. Phyllopneuste javanica (Horsfield), mentioned by Bla- 

 sius (Ibis, 1862, p. 66) as this species, or one very closely 

 connected with it, is pronounced by Sclater and Finscli (Ibis_, 

 1873, p. 475) to be a Zosterops. 



Bill large, under mandible pale. 



Upper parts greyish brown, dashed all over, especially on the 

 rump, with yellowish green. Wings and tail greyish 

 brown, with the outside edges of each feather broadly 

 margined with yellowish gi-een. Superciliary streak ex- 

 tending to the nape. 



Head the same colour as the bacJc. 



Underparts nearly white, slightly dashed with yellow and grey 

 on the breast and flanks. Axillaries, wing-lining, and 

 thighs pale yellow. After the autumn moult the whole 

 of the underparts are pale yellow, dashed with grey on 

 the breast and flanks. 



Third and fourth primaries longest. Fifth considerably 

 shorter. Sixth very considerably shorter still. Second 

 intermediate in length between the fifth and sixth. 



The bastard primanj very small. The exposed part mea- 

 sures "3 to "35 in adults, and •4 to '45 in birds of the 

 year. 



First wing -bar distinct. Sometimes traces of second wing- 

 bar in birds of the year. 



Length of wing — male 2"70 to 2*55, female 2'55 to 2*40. 



Length of tail— male 2-00 to I'QO, female 1-90 to 1-80. 



Legs and claws brown. 



This species breeds in the north of the palsearctic region, 

 at or near the limit of forest-growth, and in a similar climate 

 in the subalpine districts of Southern Siberia. It passes 

 through China on migration, and winters in the East-India 

 islands and the islands surrounding the Burmah peninsula. 

 It unites an extreme south-eastern winter-range with a wider 

 northern range than that of any other species of the genus. 

 Collett has recently obtained it in Finmark ; and it is not un- 

 common in summer at Archangel {Alston and Harvie Brown,
