r. Adult. Butagu Valley, W. Ruwenzori, 7000 ft., 1st Aug. [No. 2445. G. i.] 



Iris hazel, dark chestnut, or brown ; bill and feet brown or flesh-colour. 



One adult female (No. 1140j diflfers from the rest of the series of specimens in 

 having the upperparts more olive and less brownish, especially on the rump. 



An immature bird (No. 146) differs chiefly from the adult in having the eyebrow- 

 stripe less developed and the breast smoky grey, the middle of the throat being 

 suffused with the same colour. 



[The White-eyebrowed Crombec was found on Ruwenzori up to 8500 ft., fre- 

 quenting the dense undergrowth both in the forest-zone and below it. It was also 

 found in the Mpanga Forest. — R. B. W.]

I. 6 . Mokia, S.E. Ruwenzori, 3400 ft., 7th June. [No. 438. R. E. I).] 

 This form ranges from the Bahr-el-Zeraf and Bahr-el-Jebel to Lake Edward. It 

 appears to be the same as aS*. carncqn Reich, from Cameroon, but 1 have no birds from 

 that locality for comparison. Dr. Reichenow's description, however, seems to agree 

 with the birds from Mokia. They may be described as follows : — 



Adult male and female. Most nearly allied to S. hrachyura Lafr., but differ iu 

 having the chin, throat, breast, sides, and flanks of a much richer rufous-buff, and the 

 bill distinctly shorter. The upper surface seems to be of much the same brownish- 

 grey colour in both forms. 

 6 . Wing 2-25-2-35 inches. 

 ?. „ 2-05-2-2 „ 



Iris hazel, chestnut, or light brown ; bill dark brownish horn-colour ; feet flesh- 

 colour or very pale brown. 



With a large series of specimens of both forms the difference between the two is at 

 once apparent.
