and tarse \\ in. Irides dark. Bill dusky above ; underneath, with 

 the legs, pale amber or brownish-yellow, darker on toes. Plumage, 

 above bright yellowish olive-green ; below full siskin-yellow through- 

 out ; the cheeks and sides of neck intermediate : over each eye a 

 broad black streak reaching to the occiput, leaving the middle of the 

 head greenish, slightly flanked with ash-grey : tail dusky, its middle 

 feathers margined with the hue of the back, and the inner web of 

 the outermost white nearly throughout, as also the terminal half of 

 that of the next. Some have a slight yellowish wing-band, which 

 in others is barely indicated. 



This pretty little bird is not uncommon in Lower Bengal during 

 the cold season, and like the rest of its tribe retires to the sub- 

 Himalayan region to breed. Its bill has more decidedly the Fly- 

 catcher form than in any of the following.

Length 4| in., by 6| in. expanse : wing 2£ in. ; with primaries 

 as in C. Burkii : tail If in. Bill to gape nearly f in. ; and tarse $ 

 in. Irides dark. Bill light dusky above, amber-coloured below ■ 

 legs light yellowish-carneous, with a leaden tinge. Plumage, bright 

 olive-green above, yellower on the wings and tail : throat, cheeks, 

 supercilia, lower tail-coverts, and margin of wing, bright yellow ; 

 the belly and flanks greyish-white : greater wing-coverts tipped with 

 pale yellow, forming a slight bar on the wing : on each side of the 

 crown a broad black band ; and an intermediate narrower greenish 

 one, becoming yellower upon the occiput : upper tertiaries very 

 slightly margined at the tips with yellowish-white ; and the tail- 

 feathers have a narrow yellowish- white internal border. 



This pretty species is rare in Lower Bengal, becoming commoner to 

 the westward. The bill is narrower and the rictal setce are less deve- 

 loped, while the claws (especially that of the hind- toe) are shorter 

 and more curved, than in C. Burkii.
