black, with white and rusty-yellow spots onthe margins. The long ear-horns (of which 
the longest is 40 mm. in length) are black, on the concealed outer webs rusty-yellow, 
and on the upper middle of the inner webs along the margin white, with small black 
cross-bands. Neck, back, shoulder-coverts, and the small covert-feathers of the wing 
near the roots rusty-yellow, with blackish-brown pronged shaft-spots, and white and 
black pointed spots on the end of each feather. Large white and black spots on the 
margin of the shoulder-coverts and on the points of the outer webs. Some coverts of 
the arm-wings are similarly spotted. The roots of the wing rusty-yellow ; the ends of 
the wing brownish ash-grey, blackish-pointed, with from six to seven irregular broad 
cross-bands. On the inner side of the wing the soft coverts are pale rufous, on the 
hand-wing there are single black-brown shaft-spots. The first series of the coverts of 
the arm- and hand-wings have the anterior middle more or less grey-black. The wing- 
feathers are pale rufous on each web, with six to eight broad and line-like bands, of which 
those next the root are of no decided colour. The feathers on the under parts rufous, 
near the point white, with black shaft-spots and three to four zigzag cross-lines. Under 
tail-coverts with arrow-like shaft-spots, on the point small pronged cross-bands. Tail 
at the base rufous, with five to seven small pronged cross-bands. The tail has on the 
upper part nearly ten bands, of which the most distinct are pointed, and sometimes 
ocellated.

darker and broader drawing. The tail shows on its upper parts no predominant rufous, 
but is more of a black colour, and the broader webs of the middle tail-feathers are grey, 
dark-pointed, with light-margined arrow-like butterfly-shaped spots. The side-feathers 
of the ¢ibie have blackish shaft-spots and five cross-bands, which in O. vulgaris are 
pointed zigzag lines.
