338 SYLVIADA. 
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 hippolais has usually been attached in the 
works of British Naturalists, is not the hippolais of Con-
