 fer. Two females examined differ from the males in the following 

 respects. The under side of the neck and the breast are pale tawny- 

 avellaneous, the feathers finely vermiculated with blackish ; chin and 

 upper throat, white, the latter with a " spottj^," partly concealed 

 black anchor mark, similar in shape, but smaller than that in the 

 male, the spotted appearance due to the white tips of the feathers ; 

 lower breast, pale avellaneous but without black vermiculations ; 

 abdomen, sides, flanks, and thighs, whitish, in one specimen tinged 

 with avellaneous, becoming darker anteriorly and merging into the 

 color of the breast; under tail coverts, white; under wing coverts, 

 whitish, the lesser ones gray, the axillars black; forehead, dark 

 brownish abundantly flecked with tawny; crown, similar but the 

 tawm^ flecks replaced by fine buffy- whitish dots; occiput, lighter 

 brown, dotted with buffy white; a short black transverse band be- 

 hind the head on the nape ; dorsum of neck, bluish gray as in males ; 

 lores and broad superciliaries, buffy white, dorsally edged with a 

 line of black spots and streaks, a band from the bill to and under 

 the ejQ, cinnamon tawny mixed with black; auriculars, tawny; rest 

 of upper parts as in male, but wings and back more banded with 

 buffy white and fuscous; remiges and rectrices as in males. 



One of the adult males (Lekiundu River, Kenya Colony) is re- 

 markable in that the second, fourth, fifth, and seventh primaries 

 (counting from the outside) have white patches on the outer webs. 

 The second not only has the basal white area extending across the 

 outer web, but also has a broad subterminal white band; the fourth 

 has a white band across its middle ; the fifth has two such bands, one 

 near the middle of its length, the other subterminal. 



Five adult males present the following measurements: Wing,

 from base, 38-40 millimeters. Two adult females of somaliensis :
