more inclined to take the forehead-band as an individual cliarac- 

 ter." — Yet, Lonnberg had already in 1911 plainly pointed 

 out the difference between the Kikuyu form and the Kilimanjaro 

 form; and Grant (Zool. Res. Ruw. Exp. 1910, p. 306—307) 

 has. also emphasised the distinctive features of these two forms. 



Of the 10 full-grown individuals brought home from Elgon, 

 7 of them have entirely brownish black foreheads, while 3 have, 

 just above the nostrils, a few, very small greyish white feathers. 

 Still, no indications whatever of forehead band. Therefore it 

 should be quite certain that Kilima-Ndjaro, Elgon, Mau-Escarp- 

 ment, Nandi-Eldoma Ravine and Ruwenzori specimens are to be 

 looked upon as belonging to a different form from that occurring 

 in the Kikuyu country. 



The difference in the length of wing is surely not of much 

 value, as the following table shows. 



However, there is another difference between alhifrons and 

 hilimensis, which I found in all the specimens I have examined. 

 In the former the bill is considerably narrower at the base than 

 in the latter. 



The incomplete plumage of the young bird differs greatly 

 from the adult and reminds one much of alhifrons, inasmuch as 

 the forehead is entirely white. The adult specimens that one 

 sometimes finds with small, insignificant, whitish feathers at the 

 base of the bill, are such as have not yet assumed the distinctive 

 character of the full dress. 



Irides, bill and legs as in the preceding. 



In the Berlin Museum collections there are 6 individuals 

 from Tanganjika, all of which lack the white forehead band. It 

 appeared also as if most of them had a smaller bill than my 

 specimens. Reichenow styles them: tanganjicae.
