It seems certain to me that the male-specimens and one of 

 the female-specimens from Elgon are rather typical imherhis. 

 Three cTcT are almost exactly similar to each other and have 

 the upper parts a beautiful yellow with a faint olive-green wash, 

 giving to the upper surface a yellower colour. The whole of the 

 lower surface is bright yellow, and two of them have dark streaks 

 along the flanks. The fourth, on the other hand, having a more 

 worn dress, has the upper surface dark olive-green and the wing- 

 coverts and upper tail-coverts have outside the green edges a 

 narrow, greyish white border. 



The female specimen from Elgon differs from the three 99 

 from Victoria Nyanza. The plumage is more worn and the 

 brown edges to the feathers of the upper surface are lor the 

 most part already worn away, giving the whole upper-part a dark 

 brownish black colour. The sides of the head and fore-neck, 

 the breast and the flanks are furnished with fine, dark streaks. 

 The superciliary stripe is brownish yellow. The lower parts 

 pale brownish white. 



As regards the females from Victoria-Nyanza, one is in 

 fresh, full dress and differs so greatly from all the others that 

 1 should be inclined to believe that it belonged to another 

 species. All the feathers on the upper surface are blackish 

 brown with wide, rusty brown edgings, the superciliary stripe 

 is also rusty brown, likewise the sides of the head. Throat 

 faintly brownish white; fore-neck pale rusty brown, belly whitish, 

 the flanks pale rusty brown. No dark streaks on the underparts 

 or sides of the head. v. Someren's description (op. cit.) of 

 the immature bird in first plumage, agrees fairly well with the 

 dress of this individual. 



Another specimen (in worn dress) is similar to the above, 

 but all the rusty-brown patches are paler. Besides, it has a 

 faint indication of dark spots on the left side. 



The third specimen from here is in moult and in the colour 

 of the dress approaches the Elgon specimen. Still, the upper 

 surface is more greyish. The whole of the lower surface almost 

 white. The superciliary stripe whitish. 



Whether the rusty-brown specimens are to be considered 

 as some special form or not I cannot at present decide, inasmuch 

 as too little material for comparison has been at my disposal.
