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 j)art 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 niuch more conspicuous in the 

 immature stage of this bird. 



The under wing-coverts, the carpal margin, and the inner
