One of the specimens reminds one of S. s. ugandae, the 

 streaks on the chest being narrow and having the colour of 

 the under surface almost as brown as in that form (darker than 

 in S. s. affinis). It reminds one of the latter, in having the 

 same small, yellow feathers on the chin and fore-neck. 



The other two have broad streaks on the chest and thus 

 approach S. s. affinis, but the underpart is nearly as brown as 

 that of S. s. ugandae, and they also lack the yellow feathers 

 on the chin and fore-neck.

This single specimen, procured from the Kikuyu country, 

 is a typical albifrons, white on the forehead. Lonnberg (Birds 

 coll. Sw. Zool. Exp. B. E. A. 1911, p. 110) mentions that the 

 birds he brought home from the Escarpement had a wing- 

 length of: cf 83 mm., 9 82 mm., and he adds that the difiference 

 in wing- measurement between this race and S. a. kilimensis 

 Richm. is not great. This statement is fully confirmed by com- 

 paring the table of measurements given below.

 Mount Elgon, 6.500 ft. 



On the eastern slopes of Elgon this race was very common 

 and I met it most commonly in the glades and on the outskirts 

 of the forests, or in the trees growing in the neighbourhood of 

 the mountain streams, especially where they ran down the more 

 or less bare slopes. 



Reichenow (Vogelf. Mittelafr. Seengeb. 1912, p. 337) 

 considers that this form coincides with albifrons and he says: 

 "that a distinct form (albifrons), having a white forehead band, 

 should occur in Kikuyu seems to me very improbable and I am
