and I am now compelled to admit that my P. pectoralis was 

 founded on immature birds, though their grey faces led me 

 to think that they were adult. Dr. Reichenow (Orn. MB. xi. 

 p. 72) states that lie has also an adult bird from Cameroon 

 which he cannot separate from South African birds. Not- 

 withstanding this, I have never seen birds with the fulvous 

 chest-patch from any other part of Africa.

The young bird is of great interest, shewing that the 

 immature plumage is brown with reddish bars, and that the 

 vinous under surface has buff-coloured bars. Unfortunately 

 the skin has been prepared by a native and dried in smoke, so 

 that it is too much discoloured to describe accurately. The 

 specimen from Bulu agrees with an example from Landana 

 in the Museum in being darker grey above and darker 

 maroon-colour below than two examples from the Gold Coast 

 (Denkera) also in the Museum ; and I at first thought that 

 two forms were to be recognised, but a third specimen from 

 Denkera is absolutely undistinguishable from the Cameroon 

 and Congo birds.

The young bird killed in February has the wing 6*5 inches 

 long, and must belong to A. castanilius. The young female 

 recorded by me as of this species from Efulen, in the ' Ibis ' 

 for 1902 (p. 92), has the wing 8 6, and must belong to 

 A. toussencli. I had at that time no idea that the latter 



species had a blackish immature plumage.
