feathers isolated from the white bases. lu 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 the 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 surrounded. 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, 

 tibise, 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, from fading ; 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 elhibit 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 o£ 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
