has since identified with P. strepitam of Reichenow; and J think 

 that, ou a comparison of the type, P. rufescens of Jiartlanh (Orn. 

 Centralbl. 1 SS^, p. !»1) Mill likewise be found to he identical. 

 My P. pamper may also turn out to he the same ; but it is not so 

 rufous in tint and rather more of a vinaceous brown ; this difference, 

 however, may be only seasonal.

This species seems to me to have a seasonal plumage, as 

 Dr. Donaldson Smith's specimen is so very much darker than 

 the types and Mr. Hawker's example from Daraweina. The chin 

 is nearly black, and the dusky bases to the feathers of the throat 

 and fore-neck are much more pronounced and have the edges sandy 

 buff, so that the whole appearance is much more scaly. The 

 colour of the abdomen and the brown of the upper surface 

 are much darker.

Specimen d is paler above and below than the other three, 

 which agree with the series in the Museum collected at Lado by 

 Emin Pasha. The wing is given by me (7. c.) as 3-5 inches, and 

 this 1 find to be the largest dimension in the Lado scries, the 

 wing ranging from 3*2 to 3*35 in the five specimens before me. 

 In the female from Magois the wing is 3-4 inches, and in the Omin 

 bird 3*5, these dimensions approaching those of the true A. rub\ 

 ginosa, the wing of which is given by me (1. e.) as 3*8 inches,
