[This species belongs to the stout-billed, black-headed group 

 of Weavers, and its affinities appear to be mostly with F. dimi- 

 diatus, P. badius, and P. capitalis, ii'om all of which it differs 

 in the black of the head extending over the whole of the throat, 

 and from P. capitalis, moreover, in its deep chestnut chest; 

 from P. badius in the absence of chestnut on the upper 

 parts, and from P. dimidiatus, possibly its nearest ally, in the 

 chestnut of the breast extending over the flanks and shading 

 the under tail-coverts. — G. E. S.]
