darker, transversal band. If one examines such a feather under 

 magnifying power it will be seen that these bands have arisen 

 because of the fact that the radii ramorum have partially disappea- 

 red curvedly across the feathers. Each feather, as a rule, has 

 3 such curved bands, which, when the feather is held up to the 

 light, appear of course lighter, but when lying along the surface 

 of the lower body give an impression of a darker band (as the 

 coloured vexillum of the underlying feathers shines through). 



Only two individuals out of the 12 latter have a narrow 

 black band along the shaft of the extreme rectrices, all the 

 others have these feathers entirely white and all have the black 

 bar or patch in front of the eye, mentioned by Z e d 1 i t z 

 (op. cit.). 



The length of the wing in these 6 birds is as follow: 

 cTcf 149—154 mm, 99 148-151 mm. 



Irides in all dark brown; bill black; legs dirty coral-red- 

 pale blue lilac.

Of this new species I brought home only one specimen 

 from Victoria Nyanza. When I went through the collection at the 

 Berlin Museum, I did not find a single specimen closely resem- 

 bling mine. Both Prof. A. Reich enow and Prof. 0. Neumann 

 acknowledged that I was right in maintaining that this specimen be- 

 longed to an unknown species which could not be referred to 

 any of the "form circles" known at present. 



The forehead is light grey-brown, the crown and occiput 

 dark grey-brown. The sides of the neck light yellow-brown, 

 cheeks grey, throat white. An indistinct black occipital band 

 bordered at the top by a wide yellowish brown band, fringing 

 the dark grey-brown occiput. Back, scapulars, wing-coverts 

 upper-tail-coverts and the two median rectrices earthy-brown, 

 the latter being dark greyish blue at the base. The primaries 

 dark-brown, the coverts of the secondaries and primaries black. 

 The throat, the fore- neck and breast yellowish brown, like the 

 flanks. The belly and the undertail coverts white. Lower wing- 

 coverts brown, with dark patches here and there. The rectrices, 

 except the two median ones, earthy-brown with dark-grey base 

 and grey wash, tipped with white. 



Bill black, irides citron-yellow. Around the eyes there are 

 naked parts with small, red wart-like formations. Feet pale 

 red lilac. 



Wing 144 mm, tarsus 22 mm (middle toe without claw 23 mm), 

 total length 250 mm, culmeu 18,5 mm, tail 40 mm.
