Zedlitz's point of view that year, but later on he gives up 

 this opinion. 



Ail the 6 individuals shot in the neighbourhood of Nairobi 

 are however typical amhiguus, inasmuch as all of them have the 

 white spot on the wing confined to the primary coverts, and not 

 extending to the outer-web of the greater coverts.

The three specimens of this race cannot be placed under 

 the i)reccdiug or to L. ae. aethiopicus (or if these two are syno- 

 nyms to this form), inasmuch as they have two of the inner se- 

 condaries with white ed^es to the outer-web. The pale salmon- 

 coloured wash on the under surface — as Reich enow points 

 out — is as a rule more pronounced in this form than in the 

 preceding.

V. Someren (Nov. Zool. 1918, p. 277) calls this race 

 common on Elgon. In the regions through which our expedition 

 passed on the eastern slopes I only saw it once. It was found 

 in the brushwood along a small mountain stream. 



It agrees entirely with Reichenow's description, but it 

 should be added that the feathers of the tibia are not white — 

 like those of the underparts and lower tail-coverts — but are 

 pale yellowish-brown. Perhaps v. Someren (op. "cit ) is correct 

 in saying that the Elgon form is different from the Cameroon, 

 but I have compared this specimen with some 20 birds in the 

 Berlin .Museum (from Cameroon, Tanganjika, Kiwu) but cannot 

 find any difference between West Africans and East Africans. 

 Wing, 88 mm. tarsus, 30 mm.

This bird lives its secluded life in the exceedingly dense 

 brushwood along the shores of Victoria Nyanza. Z e d 1 i t z has 

 given an exhaustive account thereof in J. f. 0. 1910, p. .799.
