Birds from British East Africa and Uganda. 275 



Total length in flesh: 20^ inches. Wing: ^ 193 ram. 



This specimen is rather worn and faded and is assuming 

 new feathering. 



[Irides brown ; bill red, white, and black ; bare skin at 

 base of lower mandible blue-red; legs and toes black.] 



Of this species L. sibbensis Sharpe (Bull. B.O. C. vol. iv. 

 1895, p. xxxii : Sibbe) becomes a synonym, as pointed out 

 by Reichenow, Vog. Afr. vol. ii. 1902, p. 266. 



Cabanis' plate shows the figure of a female with a black 

 bill, and Sharpe's diagnosis reads, " et rostro toto nigro dis- 

 tinguendus." Besides which the type is now lying before me.
