feathers isolated from the white bases. In the fuliginous bird 
to which I am now referring^ the secondaries are tipped with 
white^ and the primaries also^ but more narrowly, in both 
which respects they resemble those of the adult C.pectoralis — 
but, unlike them, without any trace of transverse bars, the 
outer webs being merely mottled irregularly with white. 
Some newly acquired secondary feathers resemble thei older 
ones in all respects; several new feathers which are apparent 
in the mantle similarly resemble in character the older fea¬ 
thers by which they are surroundedi The wing-linings are 
fuliginous, but much varied with white, especially in prox¬ 
imity to the metacarpus ; the axillaries are pale fuliginous ; 
the feathers on the under surface of the body are a darker 
fuliginous, with irregular white bases, except on the flanks, 
tibiae, and under tail-coverts; the new feathers on the breast 
and abdomen, of which many are apparent, only differ from 
the older ones in the latter being paler, froin fading j the 
under tail-coverts are fuliginous, with white tips and two 
white transverse bars, which on some of the feathers are 
broken into two white spots, one on either side of the shaft. 
(No. 13.) This is also a specimen from Natal, and is pre¬ 
served in the Liverpool Museum; it agrees generally with 
No. 12, and, like it, has three narrow whitish bars across the 
tail, besides the white tip ; the upper tail-coverts exhibit from 
two to three narrow white transverse bars and a white tip. 
(No. 14.) A dark newly moulted bird from Natal, in the 
British Museum, is very similar to Nos. 12 and 13; but the 
tail has only two light narrow transverse bars, exclusive of 
the pale tip; many of the abdominal feathers exhibit two 
brown spots on the white base, one on each side of the shaft. 
(No. 15.) A South-African specimen, also in the British 
Museum, resembles No. 14, but is rather less darkly coloured; 
it has a less proportion of white on the bases of the abdominal 
feathers, and none on the under tail-coverts. There are four 
narrow pale bars on the tail, besides the tip; but the upper- 
most one is imperfect. 
(No. 16.) A fuliginous specimen in the Museum at Brussels 
has five narrow pale bars on the tail; but in this also the
