006 Mr. W. R. Ogilvie-Graut on 



Lake Zwai iu January and February ; it was also met with 

 at Gofa, Lake Rudolf, Kouso and Kambata, between July 

 and September. 



One somewhat immature male exhibits a variation in 

 plumage, having the genei'al eolour above pale rufous. 



I have spent some considerable time in studying the 

 various forms of this widely distributed African species and 

 h;ive discussed them with Mr. W. L. Sclater, but as he is at 

 present engaged in working out the genus Cisticola I do not 

 propose to offer any remarks on this puzzling group.

Hinders Grass-Warbler was only met with at Yeka, near 

 Addis Abbaba, on the 30th of September. There can be no 

 doubt that Heuglin's name, C. brmwescens, refers to this 

 si)e(nes. The male has the middle of the crown nearly 

 uniform rufous-buflf, with a dark streak over each, eye and a 

 black patch on the lores in front of the eye ; the female has 

 the crown of the head streaked with black like the back ; 

 and both sexes have a very distinct blackish patch on each 

 side of the chest.
