I have re-examined the large series of Grass-Warblers, which I at first considered 

 to represent a distinct species and separated under the name of C. woosnami and am 

 now satisfied that they should have been referred to G. emini Reich. 



The species is nearly allied to C. pileata Reich., and, like that species, has the lores 

 white, but the bill is shorter, the culmen more curved, the under mandible always pale 

 horn-colour, the top of the head browner, not chestnut, and the upperparts much 

 lighter and of an olive-brown. Iris hazel ; upper mandible black, lower mandible 

 whitish horn-colour ; feet flesh-colour. 



The male, besides being larger than the female, is easily distinguished by having the 

 sides and flanks olive-grey : in the female these parts are bright buff. This sexual 

 diff'erence in plumage explains the difi'erences noted in the bird collected by 

 Mr. Carruthers at Baraka [cf. ' Ibis,' 1908, p. 297). 



Young birds have the upperparts, including the crown, uniformly reddish-brown • 

 the chin, throat, and middle of the breast being washed with yellow, as is usual amono- 

 young birds of this genus.

[Although Emin's Grass- Warbler so closely resembles C. ckuhbi in appearance, both 

 its habits and notes are totally difl"erent and it frequents a different kind of country. 

 C. chiibbi, which is found on Ruwenzori from 5000 to 8000 ft., is essentially a bird 

 of the elephant-grass country, and is never seen among the short grass and acacia- 

 trees at the south end of the range. C. emini is met with only in the acacia-countrv
