This species may be recognised from the allied African 

 Grey Flycatchers by having the base of the lower mandible 

 whitish, a white band from the nostril to the eye, and a 

 white line of plumes above and below tlie eye, the inner 

 secondary quills margined with white, and the primaries 

 narrowly edged extei'nally with whitish. The general colour 

 above is rather pale grey; the throat white, the sides being 

 rarely tinged with greyish ; the breast and flanks pale grey, 

 and the belly and under tail-coverts white. 



From M. c. cintrea it is distinguished by its larger size 

 and longer tail. The wing-measurements are : ^ 78- 

 84 mm. ; ? 77-83 mm. Tail ^ 60-66 mm. ; ? 59-6f mm. 

 Specimens procured by A. S. Neave in Northern Rhodesia 

 and the Katanga district are rather larger than any of the 

 rest of the series.
