The female of this Weaver-bird is distinguished from 

 the male by lacking the black throat. The bird described 

 and figured by Shelley as an adult male is iu reality a 

 female. 



An immature female (No. 8) has already assumed the 

 yellow throat, and the underparts are mottled black and 

 yellow. 



No. 4 is a younger bird, and the underparts have not 

 commenced to change from the olive to the black. 



No. 6 is even younger than No. 4, and is practically 

 indistinguishable from the young of H. stejjhanophorus from 

 Ruwenzori. 



The series which Alexander has obtained is particularly 

 instructive.
