are of the same fulvous-brown as the hack, hut 
darker, the middle of each feather having a blackish 
line ; the whole are separated by an obsolete black 
band. The second range of the lesser covers become 
suddenly very light, and the black stripes are longer 
and fewer; the greater covers are cream-coloured 
white, with rather a broad hand of black near their 
tips, and which leaves a narrow white line on their 
outer edge ; lesser quills entirely black. The greater 
quills are also black, but the seventh, eighth, and 
ninth are white at their base and tips, and the first, 
second, and third white nearly to their middle ; 
these white spots are very unequal in size, and they 
extend to both w r ebs. The lateral tail-feathers are 
all white, with broad black tips, and most of them 
have crescent-shaped bands on their basal half; 
these bands disappear as they approach the middle 
pair, which are brown and unspotted. Under tail- 
covers fawn-coloured ; the first quill is rather shorter 
than the second and third.

2 t % ; ditto from the front, 1 1 ; wings, 8 ; tarsus, 2 I 7 5 ;
