1) The Melsttophagus boleslawski, known from specimens taken on the Blue Nile, above Khartoum, and in Southern and 
Eastern Sennar, is to be considered as an occasional aberration, in which the red throat is replaced by yellow. 
2) Birds from the Guinea-coast have the head strongly suffused with blue and a blue edge before the black terminal 
band of the secondaries, but to a lesser degree than in the next form. 
3) A specimen from there has the hind part of the cheeks and the superciliary stripe more suffused with light-blue 
than those from the Kilima Ndjaro.
