Adult male. Iris brown, dark brown, or hazel ; bill brownish-horn-colour ; feet 

 brown. The blackish streaks on the back seem to vary considerably with age. In 

 what appears to be the oldest male (No. 1403), with the brightest olive-yellow back, 

 they are much reduced, taking the form of narrow shaft-streaks ; while in a second 

 male (No. 3059), marked " breeding," the feathers of the upperparts are olive with black 

 middles, producing a somewhat spotted appearance. 



As the female of this species does not appear to have been described, I take this 

 opportunity of characterizing it : — 



Adult female. Differs from the female of C. citrinelloides (Ri'ipp.) in having the 

 yellow band across the forehead and the yellow eyebrow-stripes well developed and the 

 underparts uniform yellow. In both these respects it resembles the male of C. frontalis, 

 but is not quite so brightly coloured below, while the narrow black frontal band, black 

 sides of the face and chin of the latter are absent, the lores and cheeks bein«- olive- 

 green and the chin yellow. 



Iris dark brown or hazel ; bill brownish-horn, lighter on the lower mandible ; feet 

 brown or light brown. 



Total length ca. 4'5 inches ; culmen 0-55 ; wing 2"55 ; tail 1'8 ; tarsus 0-55. 



The young female is much browner than the adult and has the plumage of the under- 

 parts soiled yellow, with the chest, upper breast, sides, and flanks streaked with dusky. 



[Reichenow's Yellow-fronted Canary was plentiful on both the east and west sides 

 of Ruwenzori up to an elevation of 7000 ft. It was also seen at Fort Beni. — R. B. W.
