 other known to me, is very similar to F. gariepensis, but 

 may be easily distinguished by the black chest , each feather 

 of which has a subterminal cordiform spot of white, in

 surface has a grayer tinge , and the cross-bars are narrower, 

 fainter and are rather mere vermiculations than real 

 cross-bars.

 on head and hind neck with broad dark brown or even 

 blackish centres , those of the back and upper wing-coverts 

 irregularly blotched with dark brown , narrowly vermicu- 

 lated with buff and , especially the scapulars and inter- 

 scapulary feathers, broadly striped with fulvous or white 

 shaft-streaks. 



The outer pairs of tail-feathers are uniform earthy brown, 

 the innermost ones and the upper tail-coverts are vermicu- 

 lated in the same way as the back. The primary coverts
