W. E. OGILVIE-GEANT— AVES. 323 



All the male specimens in the present collection clearly belong to this rather larger, 

 longer-billed, and greener-throated form of G. verticalis (Lath.). The West African 

 birds have the bill somewhat shorter, and as a rule the throat is distinctly blue, 

 though in a large series a few specimens which are intermediate as regards the colour 

 of the chin and throat can be found. Moreover, the male of G. verticalis has the 

 breast and underparts of a blackish-grey tint (in G. viridisplendens these parts are 

 dark grey) and the female has the underparts of a soiled white tint, relatively much 

 lighter than in G. viridisplendens, which is grey below and rather darker on the throat 

 and chest. 



Young males of G. viridisplendens in first plumage have the crown bright olive, 

 with a few metallic-green feathers on the throat, the chest blackish mixed with some 

 metallic-green plumes, and the rest of the underparts yellowish-olive. 



Young females have the crown like that of the young males, but the throat and 

 chest are yellowish-olive like the rest of the underparts. 



[The eastern form of the Green-headed Olive Sun-bird was obtained near Entebbe, 

 and was met with throughout the journey to Ruwenzori; it was not seen on the 

 mountains above 7000 h.—R. B. W.]
