286 ZOOLOGICAL RESULTS OF THE RUWENZORI EXPEDITION. 



2 adult males from Niger district. With a narrow line of black feathers. 

 Landana. With some black feathers. 

 Lower Congo. One specimen with a narrow line of black feathers and 



one without. 

 Benguela. With two rows of black feathers. 

 Nyasaland. Some with black feathers, others without. 

 Zanzibar. With one line of black feathers. 

 Pangani. Without any black feathers. 

 Malinda. As above. 



Mombasa. With a single row of black feathers. 

 Abyssinia. With two rows of black feathers. 

 Tingasi. Two specimens with a narrow black band across the base of the 



culmen, one with a single line of black feathers, and one without 



any black. 

 Nandi. With a well-marked black band. 

 Lower Semliki River. As above. 



It is thus evident that the black band across the forehead, when present, is most 

 developed in birds from Equatorial Africa, but since specimens both with and without 

 a black band occur in the same locality, it is obviously a character of little importance.

Adult female. Iris dark brown ; bill and feet brown. 



In male specimens in breeding-plumage the amount of black on the chin varies 

 greatly ; in some specimens there is only a trace of it, while in others the whole chin 

 is conspicuously black. In examples procured from S.E. Ruwenzori the mantle varies 

 from uniform cinnamon slightly washed with red to cinnamon washed with scarlet 

 and laterally streaked with black. 



It. would appear that the specimens procured by Doggett and referred by me to 

 P. tvertheri Reichenow (cf. 'Ibis,' 1905, p. 207) are merely paler-backed forms of
