of North-eastern Africa. 95 



vanes of the latter broadly white or yellowish -white ; the duller 

 fawn-eoloured upper tail-coverts are not streaked with black ; 

 eyelids and middle of throat and belly tolerably pure white. 



Lives in pairs in the reed-thickets of the Upper Abiad and 

 Gazelle Rivers and on the Lower Bahr el Djebel, from which, 

 especially in the morning, we frequently heard the song and 

 call-note of this bird. 



Described from three specimens differing very inconsiderably 

 from each other in the Museums at Vienna and Stuttgart. Dr. 

 Finsch regards I)rym(£ca marginata as identical with Drymceca 

 erythrogenys, but without having directly compared the birds. 

 It is impossible to confound them.

The rectrices, especially the two middle pairs, have nearly the 

 whole of their outer vanes yellowish fawn-coloured, and their 

 inner vanes more smoky-blackish, like the shaft, and a very 

 narrow stripe along the latter on the outer vane ; the reetrices 

 are sometimes washed with yellow upon the ground-colour of 

 the upper surface.
