96 BIRDS OF SOUTH AFRICA. 



of the feathers : these are nearly obsolete on the head, but 

 extend along the centre of the tail-feathers. 



Under parts, uniform light Isabella-coloured, everywhere 

 mottled with dark black-brown streaks, most evident on the 

 flanks. Length, 8" 9'" ; wings, 3" ; tail, 4". 



The plumage of this curious bird is of a singularly lax texture ; the 

 tail-feathers are long, pointed, and graduated, and furnished with 

 webs, so thin that they are transparent ; the shafts projectjbeyond the 

 webs, which are fined down to a point. Wings small and weak, hardly- 

 enabling the bird to fly fifty yards. If flushed more than once, it 

 betakes itself to a clump of grass, or bush, and will suffer itself to be 

 taken with the hand rather than rise again ; for this reason it has 

 acquired the name of "Idle Jack" and "Lazy Dick."
