I add a more detailed description of the two specimens 
which are in the collection—one of them being evidently 
an adult; the other a young bird, which differs in many points 
from it. 
Adult. The upper parts of the body are of a dark cinereous 
colour, with a slight shade of olive admixed with it. The top 
of the head is much darker, rather blackish, and here each 
feather shows a thin white stripe occupying the shaft from 
the base till about the end of the feather; these stripes are 
more conspicuous on the fore part of the front, where the 
feathers are rather firm and rigid and acutely pointed. On 
the hind neck, and more so on the sides of the neck, there 
are likewise indications of white stripes down the feathers, 
but they are only to be seen when the feathers are disturbed. 
The lores are white, but obscured by blackish margins to the 
feathers, which also form a black line dividing the lores 
from the superciliary stripe. The white superciliary stripe 
itself, which is very broad and conspicuous, begins at the 
nostrils, where it has a strong yellowish or fulvous suffusion, 
and then becoming of a purer white, extends over the eye to the 
side of the nape, where it ends in an acute tip. The feathers 
of the region under the eye are whitish, with blackish tips; 
the ear-coverts blackish, striped down the centre with 
whitish. 
All the underparts are of a uniform soiled white, somewhat 
suffused with yellowish. On the sides of the breast there 
are a few indistinct blackish spots, being, no doubt, the 
remains of a feature which is much more conspicuous in the 
immature stage of this bird. 
The under wing-coverts, the carpal margin, and the inner
