black, while another has the middle of the throat mostly yellow and closely resembles 

 the type o{ S. meiitalis. There can be little doubt that the type of S. nandensis is a 

 female of the present species, and that the name should be added to the synonymy. 



In the type of S. mentalis (a male) the wing measures 3'4 inches ; in five males from 

 the Mpanga Forest the wing measures 3"l-3-3 ; and in the type of S. nandensis 

 (a female) it measures 3"2. 



[The Black-chinned Grey-backed Weaver was not uncommon in the Mpanga Forest, 

 and was also observed in the Congo Forest. — R. B. W.~\

Adult male and female. Iris white or pale yellow ; bill black ; feet brown, light 

 brown, or flesh-colour. 



Immature. Iris hazel or dark brown (one marked " grey ") ; bill and feet brown. 

 The immature bird differs from the adult in having the top and sides of the head 

 olive-green ; the mantle and back greenish-olive, more heavily streaked, and the 

 underparts paler yellow, washed with buif, especially on the flanks. 



: This species was not previously represented in the British Museum, though there 

 were two examples in Mr. Jackson's collection. 



Dr. Keichenow describes the female of H. stuhlmanni as having the belly white, 

 washed with brownish, and the under tail-coverts pale golden. Captain Shelley, on 

 the other hand, says that the female is nearly like the male in plumage, with the 

 entire underparts bright yellow. This is no doubt the case, as all our female specimens 

 differ from the males only in having the olive-green of the nape extending on to the 

 occiput, whereas in the males the entire top of the head and nape are black. The
