338 SYLVIAD^. 



Mr. Blyth has found this species in the neighbour- 

 hood of Calcutta. 



This little bird has the beak shorter and narrower at the 

 base than that of the Willow Warbler ; the legs very dark 

 brown, and the general tone of the colour of the plumage 

 has more of brown and less of green than that bird ; it 

 is on this latter account, probably, that the Chiff Chaff has 

 also been called the Lesser Pettychaps, its plumage bear- 

 ing some resemblance to the brown colour of that of the 

 Garden Warbler, which has been frequently called the 

 Greater Pettychaps as shown by the synomymes. 



The adult male has the beak dark brown ; the irides 

 brown ; over the eye a light-coloured streak, sometimes 

 rather obscure ; the head, neck, back, wings, and tail- 

 feathers, nearly a uniform ash-brown ; the quill-feathers 

 rather darker than the other parts, the edges of the ter- 

 tials rather lighter ; the chin, throat, breast, belly, and 

 under tail-coverts, dull brownish white, tinged with yel- 

 low ; under wing-coverts primrose-yellow ; under surface 

 of wing and tail-feathers grey ; legs, toes, and claws, dark 

 brown, almost black. 



The whole length of the bird about four inches and 

 three-quarters. From the carpus to the end of the longest 

 primary two inches and three eighths : the first feather 

 short ; the second about as long as the seventh, and nei- 

 ther of them so long as the fifth or sixth ; the third and 

 fourth nearly equal in length, and the longest in the wing. 



The plumage is similar in the two sexes. Young birds, 

 like the young of the species last described, are more 

 tinted with green and yellow than very adult birds. 



It should be borne in mind, that the British Bird to 

 which the term Uppolais has usually been attached in the 

 works of British Naturalists, is not the Mppolais of Con-
