100 RIVER WARBLER. 



white; under wing and tail coverts, and all the under 

 parts of the belly whitish, shaded with light olive green; 

 the anterior jDart of the neck mottled with olive green 

 and ash-colour. Primaries rich brown; first the longest, 

 and the others gradually a little less, down to the ninth, 

 giving the wing a long pointed character. This gradu- 

 ated position of the primaries is shewn when the wing 

 is in repose. The beak is dark brown above, light be- 

 low. Tarsi light yellow; iris, dark brown. 



The female has the upper parts like the male; the 

 throat, neck, and crop dirty white, feebly marked with 

 long spots of ashy brown. In autumn the feathers are 

 bordered with ash. 



My figures of this bird and its egg are from speci- 

 mens sent me by M. E. Verreaux.
