Adults. Intermediate in plumage between C. scnerjalensis and 

 C. sitperciViosus. The white eyebrow, when present (which is not 

 always the case), varies from a mere spot near the nostril to almost 

 a complete eyebrow as in C. superciliosus, but it is always interrupted 

 above the eye by the black of the crown which descends to the 

 upper eyelid ; generally, bnt not always, some of the feathers of 

 the back of the neck and mantle have white shaft-stripes ; rump, 

 upper tail-coverts, and basal portion of the tail always narrowly 

 and distinctly barred with buff as in C. superciliosus : tail-feathers 

 narrowly tipped with white ; sides of the throat generally streaked 

 with black, but never to the same extent as in C superciliosus ; sides 

 of the body and the under tail-coverts more or less barred : bill 

 black, sometimes with a portion of it yellow ; iris red ; legs slate- 

 colour. Total length 14 to 17 inches, culmen 1-25 to 1*50, wing 

 6-2 to 6-8, tail 7-8 to 9, tarsus 1-6 to 1-8. 



One specimen differs from 0. senegalensis only in having a few 

 white shaft-stripes on the wing-coverts ; and the back, upper tail- 

 coverts, and basal third of the tail distinctly barred with buff. 

 Total length 14 inches, culmen 1-2, wing 6-4, tail 8-3, tarsus 1-45. 

 The white ends to the tail have apparently been worn away. 



Another adult bird differs from the last in having a broad white 

 eyebrow interrupted by black feathers just above the eye ; all the 

 feathers of the back of the neck and many of those of the mantle 

 have white shafts ; the broad buff shaft-stripes to the feathers on 

 the sides of the neck are partially edged with black, but not to the
