Males and females from Yambuya. 



This pretty Weaver Finch was discovered by Emin Pasha 

 in Equatorial Africa, and specimens were sent home by him 

 from the Monbuttu country. Mr. Bohndorff met with it on 

 the Upper Congo, and the present occurrence at Yambuya 

 considerably increases its range to the westward.

Not to be separated from the Gold-Coast specimens. This 

 is rather an unexpected species in the Upper Congo region, and 

 is evidently a parallel occurrence to those of the Pholidomis 

 and Diaphorophya blissetti. Perhaps the adult bird may be 

 found to be specifically distinct, like Pholidomis jamesoni.

 The range of this Nigrita is also thus greatly extended.

The sexes are alike in plumage. This is a very interesting 

 extension of the range of this species.
