Reichenow (Vogelf. Mittelafr. Seengeb., p. 344), who gives the 

 distribution of the race "from Senegambia to Congo and east- 

 wards to Kikuyu", he maizes Neumann's form percivali (Orn. 

 Monatsber., 1903, p. 185) synonymous with it. Reichenow 

 (op. cit.) has already in 1904—1905 expressed the same opinion 

 with reference to the occurence of gracilirostris, although he then 

 also mentions percivali. 



However, v, Someren (Ibis 1916, p. 438) has dealt in 

 a very credible ma' ner with the different forms of gracilirostris 

 and after a careful examination of all the specimens in Tring 

 an the British Museum he has established four allied forms, 

 whose distribution he also gives, and therefore I shall not here 

 repeat these results. 



As regards two of these forms: percivali and chagwensis, 

 which I have myself had an opportunity of studying, I share 

 v. Some r en's views entirely. 



The present specimen agree perfectly with v. Some r en's 

 description and over and above that 1 have nothing to add. 



Wing 82 mm.; tarsus 22 mm. 



Irides dark-brown; bill and legs black. 



Andropadus gracilirostris chagwensis v. Someren. — 

 Bull. Brit. Orn. Club, vol. XXXV, 1915, p. 127. 



Ghlorocichla gracilirostris chagwensis v. Someren: op. cit. 



2 5(5 ad. 20. 5., 25. 5.; 1 Q ad. 7. 7.; Mount Elgon, 7.000 ft. 



This form is common in the dense forests on the eastern 

 slopes of Elgon and I have met it at an altitude of 6500—7000 

 ft. van Someren (Ibis 1916, p. 439) says "that this Uganda- 

 form frequents the tops of the tall-trees", but I have often seen 

 it in the brushwood and undergrowth in the same localities as 

 J^hyllasirephus tephrolaemus kihuyuensis. 



According to v. Someren (op. cit.) this bird occurs from 

 Uganda, east to Elgon, south to Tanganyika, west to the Congo 

 border, but this and percivali meet in the Elgon district. 



This Bulbul is also an excellent singer, and its warbling 

 song can be heard even after nightfall, v. Someren mentions 

 too that on four different occasions he has heard Fycnonotus 

 layardi sing after darkness had set in (Journ. East Afr. and Ug. 

 N. H. Soc. vol. IV, No. 8, 1914, p. 153). 



V. Someren gives 83— 87 mm. as the wing-measurements 

 for cf cT and 78—83 mm. for 99- ^J specimens measure: cfcT 

 84, 87 mm. 9 82 mm., tarsus 21—22 mm. 



Irides reddish-brown — dark-brown; bill and legs black.
