having the inner webs of the innermost secondary-quills widely margined with deep 

 black, contrasting sharply with the olive-green portion which lies next to the shaft. 

 In the female the yellow collar is paler and much narrower (much as in males of 

 0. hrachyrhynchus), and the inner webs of the innermost secondaries are olive-green, 

 gradually shading into dusky olive towards the margin. 



The nearly allied 0. hrachyrhynchus, which ranges from Sierra Leone to Togo, 

 appears to show the same sexual differences as regards the coloration of the innermost 

 secondary-quills, but in none of the specimens in the British Museum Collection has 

 the sex been determined. 



[This Yellow-collared Oriole appears to be plentiful in the Congo Forest. It was 

 not often seen, but a clear mellow note, presumably of this species, was often heard 

 from among the tree-tops. It was plentiful in the Mpanga Forest, east of Ruwenzori.

The type of this species was procured by Mr. A. B. Percival in the Kikuyu Forest, 

 and there are specimens in the Jackson Collection from Mt. Elgon and Nandi, which 

 are referred to in the synonymy given above. 



The present specimen, a female, differs only from the type in its somewhat smaller 

 size: wing 5"2 inches ; tail 3-5.

Iris dark brown or dark crimson ; bill and feet black. 



This is merely a slightly smaller form of M. rubricollis (Swains.), the bill, as pointed 

 out by Dr. Eeichenow, being much more slender than in the typical West- African 

 form. 



[Reichenow's Malimbe was plentiful in the Mpanga Forest. It was only seen among 

 the tops of the tall trees and never among the undergrowth.—^. B. W.]
