rump, wings and tail : below, with the cheeks and lower half of the 

 ear-coverts, wholly bright yellow : a whitish-grey supercilium and 

 narrow medial streak upon the crown, and two broad ill- defined 

 lateral streaks of rather a more dusky grey than that of the back : 

 outermost and penultimate tail-feathers only, white on their inner 

 webs. The young have looser plumage and all the colours less 

 intense. 



This appears to be very common throughout the sub-IIimalayan 

 territories, and is likewise met with in Arakan ; but it appears never 

 to descend from the hills. According to Capt. Hutton, it is a com- 

 mon species at 5000 ft. elevation, and commences building in March. 

 The nest would appear to resemble those of Phylloscopus trochi- 

 lus and Ph. rufus. Eggs spotless white. Vide Hutton, in J. A. S. 

 XVII, pt. II, p. 688. 



5. C. poliogenys, nobis, J. A. S. XVI, 441. 



Length 4^ in. : of wing 2\ in., with the outermost primary f in. 

 long, the second exceeding it by T 9 ¥ in., and the third ■§■ in. shorter 

 than the fourth, which equals the fifth and sixth : tail 1 J- in. : bill to 

 gape -^ in. ; and tarse f in. Bill dusky above, yellow or amber- 

 coloured below. Legs pale. Plumage, above dark olive-green, 

 slightly yellowish on rump, with a conspicuous narrow yellowish- 

 white wing-band : crown and ear-coverts dusky-grey, with blackish 

 coronal bands ; the chin, and feathers proceeding from the base of 

 the lower mandible, greyish-white : rest of the lower-parts bright 

 yellow : tail with its three outer feathers white on the inner web, as 

 in C. PULCHRA. 



We have only seen this well marked species from Sikim. It 

 might be mistaken for the preceding on a very superficial view ; but 

 besides the differences in the details of colouring, its wings are much 

 more rounded and the bill is somewhat less compressed.
