General colour of the upper parts uniform dark olive-brown, very 

 slightly more dusky on the wiugs, and very slightly paler on the 

 margins of the innermost secondaries, and more so on the outside 

 "web of the second primary ; a scarcely perceptible eye-stripe ; lores 

 and the feathers behind the eye uniform with the iipper parts ; 

 generally obscure traces of transverse bars on the tail. The under- 

 parts are greyish brown, shading somewhat abruptly into white on 

 the throat, centre of belly, under wing-coverts, and the tips of the 

 under tail-coverts ; the feathers on the throat and fore neck have 

 dark centres ; axillaries and thighs pale brown ; inner lining of 

 quills pale grey. liill typically Locustelline : upper mandible dark 

 brown, under mandible pale horn-colour ; rictal bristles scarcely 

 perceptible. Wings very slightly concaved ; second and third 

 primaries nearly equal and longest ; bastard primary very small, 

 considerably shorter than the primary-coverts. Tail shorter than 

 the wing, outside feathers Go inch shorter than the longest, and 

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

 brown. Length of wing 2-96 to 2~ inches, tail 2-5 to 2-3, culmen 

 0-6 to 0-54, tarsus 0-8. 



It is not known that there is any difference in the colour of the 

 plumage between the sexes, or that any change takes place during 

 the autumn moult. Birds of the year are said to have the throat 

 plain, without the dark centres ; but I have been unable to obtain 

 access to a skin in this plumage. 



The Eiver Grasshopper "Warbler breeds in Russia as far north as 

 Lake Ladoga, probably not extending its range westwards beyond 

 the valley of the Danube. It is also supposed to breed in Asia 

 Minor aud Palestine, probably wintering in North Africa.
