This bird is closely allied to Crithagra hutyracea, 

 L., and C. canicollis, Swains, It may be distinguislied 

 from the first by its yellow forehead being broader and by 

 the colour passing gradually to olivaceous on the crown, 

 whereas in G. hutyracea the yellow is a narrow band 

 sharply defined. There are several minor difierences also. 

 From C. canicollis it is distinguished by the back and 

 sides of the neck being olive instead of bluish grey, and 

 by both the forehead and underparts being brighter in 

 colour. It is a much greener bird than Serinus aurifrons, 

 Tristram, larger in size and with a less conical bill. C. 

 chloropsis, Cab., from Mozambique is distinguished by 

 having a much larger bill than the present species, larger 

 wings, and less yellow coloration.

This bird agrees very poorly with EiippeU's description, 

 but better with his figure, and stUl better with Von 

 Heuglin's description. I shot a pair at Senaf^ on a large fig-
