 few bristles, most abundant on the chin where they are black ; 

 above the eye a row of large black eyelashes and round the ear 

 opening a few bristles ; a narrow fold of skin about a quarter of an

 brown feathers not meeting in front but extending slightly up the 

 back of the neck; general colour above brown, becoming quite black 

 on the wings and tail, scapulars and wing-coverts edged with paler ; 

 crop patch dark brown ; lower surface including the thighs thickly 

 clothed with white down, through which project on the breast and 

 abdomen narrow lanceolate feathers of dark brown edged with 

 paler ; feathers of the underwing- and tail-coverts brown more 

 rounded in shape.
