but the two centre feathers by a nearly white apex. In older birds 

 these dark subterminal spots on the rectrices become less conspi- 

 cuous, and the dark centres to the feathers of the rump and upper 

 tail-coverts disappear altogether. Inside web of the second jjrimary 

 paler ; eye-stripe narrow and obscure ; lores and the feathers behind 

 the eye brown. The underparts are ncarlj* white on the chin, throat, 

 centre of belly, axillaries, and under wing-coverts, shading into 

 bufSsh brown on the flanks and thighs, and into pale huffish brown 

 on the breast and under tail-coverts, the latter having obscure 

 "white tips. Tail-feathers becoming darker towards the apex on the 

 under surface, and finally tipped with grejish white. Bill typically 

 Locustellioe ; u])per mandible dark brown, under maudililc pale horn- 

 colour, darker towards the tip ; rictal bristles obsolete. Wing 

 with!; he third primary the longest, and the second intenncdiate in 

 length between the fouith and fifth, in very rare cases between the 

 third and fourth ; bastard primary generally shorter than the pri- 

 mary-coverts, but in birds of the year sometimes extending 0"1 inch 

 beyond them. Tail with the outside feather 0'65 inch shorter than 

 the longest, and shorter than the under tail-coverts. Legs, feet, 

 and claws pale brown. Length of wing 2'8 to 2'4 inches, tail 2-3 

 to 2-0, cnlmcn 0-61 to 0-58, tarsus 0-9. 



There is no difference in the plumage of the sexes. After the 

 autumn moult the huffish brown of the underparts is deeper in tint, 

 approaching chestnut-brown. Birds of the year have the under- 

 parts suflused with yellow, and many of the feathers of the throat 

 have dark centres. The striation of the throat is seldom entirely 

 lost after the first spring moult, and traces of striation are often 

 met with on the flanks and the longest feathers of the under tail- 

 coverts in apparently adult birds. 



Pallas's Grasshopper "Warbler breeds in Central and Eastern 

 Siberia, passes through China on migration, and winters in India, 

 Ceylon, the Burma peninsula, and the islands of the Malay archi- 

 pelago. A straggler has been shot on Heligoland.
