Type. Very similar to N. canicapilla, especially to an immature hen, 
from Landana, but differs in having no trace of white on the greater wing- 
coverts, nor on any of the quills; most of the smaller, and a few of the 
median, wing-coverts have small pure white spots; under parts jet black, 
with the exception of very narrow, almost obsolete, whitish edges to the 
feathers of the flanks, abdomen and under tail-coverts. ‘Iris yellow; bill 
black; legs brown.’ Total length 5:5 inches, culmen 0-45, wing 2:6, 
tail 2-0, tarsus 0°7. @, 3.10.89. Sotik (Jackson). 
Male in breeding plumage. Differs in the upper parts being slightly 
paler and the lower back much whiter; little or no trace of white edges 
to the feathers of the flanks, abdomen, or thighs. ¢, 2. 7. 98. Nandi 
(Jackson). 
Young. Nearly uniform slate grey, or dusky ash, rather blacker on the 
forehead, throat, wings and tail, and a trace of ashy white on the rump; 
lesser and median wing-coverts with a few very obscure ashy white spots. 
Variety. Differs from the last in having the forehead, sides of head and 
under parts blacker, with a few ashy white feathers on the nape; rather 
less white on the rump; no trace of whitish marks on any of the wing- 
coyerts. d¢, juv. 2.7.98. Nandi (Jackson). 
Jackson’s Negro-Finch inhabits Central Equatorial Africa. 
Mr. Jackson discovered the type, a rather dull-coloured 
female, apparently in winter plumage, at Sotik on the border 
of the Mau Forest, October 3, 1889. I have also examined 
his fine series of six specimens from Nandi, and five collected 
during the expedition into the Ruwenzori Mountains. The 
winter plumage is represented by the type procured in October, 
a male killed in February, and a female in April; in these the
