5 (5(5 ad. 27. 6.-1. 8.; 3 QQ ad. 26. 6.-27. 6. Mount Elgon, 9000-13,500 ft. 



Ou the eastern slopes of Mount Elgon this bird was common 

 from 9000 ft. up to the highest regions. I have seen it practi- 

 cally everywhere from 9000 ft. on the outskirts of the forests, on 

 the shrub clad slopes, in the bamboo-forests, in the Erica wood 

 and even in the tall Senecios, which grew around the rater-lake 

 at an altitude of 13,5000 feet. It thus seems to be a pronounced 

 alpine bird, which goes considerably above the limits of the trees. 



Generally it appeared singly, but sometimes it occurred in 

 flocks of about 10 — 12 individuals. 



It is very easy to distinguish from S. s. affinis by means 

 of the considerably darker under surface, which is distinctly 

 brown [yet according to v. Someren (op. cit.) not so dark as 

 in S. s. graueri]. Besides, the blackish streaks on the chest are 

 narrower that in the latter. The yellow feathers on the chin 

 and fore-neck, found in all my specimens of S. s. affinis, are, 

 as a rule missing in this form, or are only slightly indicated, 

 and have not, at any rate, the bright, yellow colour as in that 

 race, but are pale yellowish green. 



v. Someren calls his specimens from VVest-Elgon (Nov. 

 Zool, XXV, 1918, p. 282) S. s. affinis. But undoubtedly they 

 are S. s. ugandae, although the author had not yet a clear opi- 

 nion with reference to (he difference between these two forms.

2 (5(5 ad. 7. 5. ; 1 S ad. 7. 5. N. W. of Londiani, 8.700 ft. 



These three specimens were shot about two days' march 

 north-east of Londiani (on the road to Eldoret). They are 

 intermediate (so-called subtile) forms between the two last- 

 mentioned. 



According to Richmond (The Auk 1897, p. 157) S. s. 

 affinis is found from 5.000—7.000 ft, and according to my own 

 observations S. s. ugandae is an alpine form, whence the speci- 

 mens found at 8.700 ft. in an area which lies between the limits 

 of these two altitudes, are intermediate between the preceding 

 forms.
