101. Phylloscopus fuacata homeijeri (Dyb.) [410A]. — Homeyer's Dusky 



Willow- Warbler. 



This Willow- Warbler puzzled me for some considerable time until Dr. 

 Hartert kindly went over my specimens and identified them as this form. 

 Specimens secured at Rungagora, Komolabari and Dejoo in April; seen 

 at Silonibari, 1-10-1 1", 3-5-11*, 22-5-11''- , so that its range is fairly exten- 

 sive in the plains during the cold season. It is a difficult matter to 

 discriminate between this northern form and the typical one, particularly 

 when on the wing. Not previously recorded from within our limits. The 

 types were described from Tigil in Kamchatka. 



Very aquatic, partial to sedgy growth along the banks of streams and 

 in the beds of " jans" or "nullahs".
