Female. Differs from the full plumaged male in having no yellow nor 

 black on the plumage ; forehead and crown pale brown ; sides of head, chin, 

 throat and crop isabelline like the entire under parts. Culmen 0'5, wing 

 1215, tail 01, tarsus 0-8. Yambuya (Bonny). 



The Anomalous Weaver inhabits the Upper Congo district. 



The type, a male in imperfect plumage, was discovered by 

 Bohndorff at Stanley Falls, on the Equator. In the Tring 

 Museum there are three specimens, obtained by Bonny during 

 the time he was stationed at Yambuya with the unlucky rear- 

 column of the Stanley Expedition for the relief of Erain Pasha. 

 These include a male and two in the plumage I here describe, 

 as that of the female. Recently the British Museum has been 

 presented with two, apparently fully adult males, by Mr. J. J. 

 Harrison, who obtained them at Jabbir on the Bomikandi 

 River, a northern tributary of the Congo, and this is all that 

 is known regarding the species. 



Genus XX. PACHYPHANTES. 



Characterised by the very stout bill and in the throat being black in full 

 plumaged birds of both sexes. It is similar to Hyphantornis in general 

 structure, but is rather compactly built and resembles Othyphantes in the 

 females having as much black on the head as in the males, in this case more, 

 the crown being black in full plumaged females and yellow in the males.
