sometimes well defined, but in new plumage not very distinct ; and 

 in much worn or abraded plumage, it often disappears altogether, 

 and the upper-parts are then dingy greyish-brown, with scarcely a 

 tinge of green : two conspicuous yellowish-white bars on the wing, 

 the hinder more broad ; and behind this is a dark patch, correspond- 

 ing to the black seen in Eegulus : tertiaries conspicuously margined 

 with whitish (as more or less in Eegulus), and secondaries and 

 some of the primaries slightly tipped with the same : axillaries, with 

 the fore-part of the wing underneath, pale yellow : supercilia and 

 lower-parts greenish-albescent. 



Common in Lower Bengal, where a few perhaps breed ; but the 

 great majority retire to the mountains for that purpose.* As an 

 exceedingly great rarity, it has been met with in Dalmatia and in 

 England. Habits as in other species of Phylloscopus, and not (as 

 in Eegulus) gregarious : song-note nearly similar to that of Ph. 

 sibilateix, but considerably weaker.

Eesembles the last, but is smaller, with bill conspicuously shorter 

 and darker-coloured, and the rump pale canary -yellow, strongly con- 

 trasting with the hue of the back ; the median coronal line much 

 more conspicuous, and the pale margins of the tertiaries less so. Its 

 size is that of the European Eegulus ceistatus. 



Length 3| in., or a trifle more : wing 1| to 2 in. ; its first primary 

 ^ in., the second i in. shorter than the third, which does not equal 

 the fourth and fifth. Bill to gape about ^ in., and tarse f in. : tail 

 1 i in. to If in. Upper mandible blackish, the lower pale except 

 towards tip. Legs pale. In other respects like the last, from 

 which it is at once distinguished by its pale pure yellow rump. 



This minute species appears to be peculiar to the sub-Himalayan 

 region, where extensively distributed. *■* 



Genus Eegulus, (antiq.,) Cuvier. 



Capt. Hutton states that both E. ignicapillus and E. ceista- 



* A reputed nest, taken near Calcutta, is described J. A. S. XII, note to 

 p. 965.
