pale salmon-coloured tint on the upper breast, which I do not 

 recollect to have met witli in C. typus. The immature speci- 

 mens of C. typvs, however, approach more closely than the 

 adults to tlie adult plumage of C. ruficoflls, the cross-harring 

 on the upper surface of the immature C. typus being as ex- 

 tensively distributed as in the adult of C. ruficollis, though, 

 except on the tcrtials and rectrices, it is paler and less strongly 

 marked. I may also mention that the young birds of C. typus 

 have the lesser wing-coverts edged with brown, and short dark 

 shaft-marks on the feathers of the upper breast. 



In C. rvficollis the young bird has the plumage throughout 

 of a darker hue than the adult; this is especially the case on 

 the crown of the head, where the rufous tint is deeper than 

 in the adult, and, in addition, each feather has a somewhat 

 broad black shaft-mark ; all the feathers of the upper part 

 of the mantle are more or less edged with rufous brown, this 

 edging being broadest on the lesser wing-coverts ; the trans- 

 verse bands on the lower surface are less regular than in the 

 adult, and all the intermediate spaces are a rich fulvous 

 instead of being white as in the old bird. I have here noted 

 these details, as Mr. Sharpe does not refer to the immature 

 plumage of either species. 



]\Ir. Sharpe gives " the whole of Africa " as the habitat of 

 C. ruficollis ; but it is absent from the northern portion of 

 that continent, not extending further northward, so far as I 

 am aware, than Senegambia towards the north-west, and 

 Nubia towards the north-east ; and I must add that the only 

 evidence I have of its extending to Nubia is a specimen in 

 the Norwich Museum, which was stated to be Nubian by the 

 late Jules Verreaux, through whose hands it passed into that 

 collection. It appears, however, to be a common species 

 in Sennaar, and also to occur, though less abundantly, in 

 Abyssinia.
