10 Mr. D. A. Bannerman : A Revision 



becoming whitish on the belly ; under tail-coverts grey, A 

 very important point is that the tips of the outer tail- 

 feathers are greij on both webs (specimen described, No. 98, 

 Alexander Coll.). 



The adult female has the upperparts very much broivner 

 and lighter, and only slightly glossed with olive on the back, 

 rump, and vrings. The mantle is similarly glossed to the 

 male, but not quite so bright. The underparts are of a 

 grey-brown, but the tips of the outer tail-feathers are only 

 grey on the inner web (specimen described. No. 64 *, 

 Alexander Coll. : breeding when shot). 



The young male has the upperparts similar to the adult 

 female just described, but the underparts are pale umber- 

 brown tinged with rufous or buff. As the bird becomes 

 older the belly becomes whiter, and the breast begins to lose 

 the brown colour, and it gradually assumes the grey breast 

 of the adult and the darker back. Again, the tips of the 

 outer tail-feathers are grey on both webs as in the adult 

 (specimens described, Nos. 83, 103, 101, and 55, Alex- 

 ander Coll. : showing change of plumage). 



A moulting bird (No. 102) shows the transition-stage 

 between the immature and adult phase of plumage. 



The young female has the upperparts lighter brown than 

 in the adult female and immature male, and there is a dis- 

 tinct pinkish gloss on all the feathers. The mantle and 

 sides of the head are strongly washed with pinkish, which 

 in certain lights becomes pale green. The underparts are 

 similar to those of the young male, i. e., umber-brown tinged 

 with rufous (specimen described, No. 105, Alexander Coll.). 



Only one bird remains to be described, and this is in very 

 peculiar plumage and has puzzled me much. It is No. 27 

 (?sex). Lake Amelia, and is obviously not fully adult, as 

 it still retains one of the rufous-edged secondaries of the 

 first plumage in the right wing. It is remarkable, in having 

 the grey on both webs of the outer tail-feathers shading 



* In my paper on the Birds of St. Thomas, I remarked that this bird 

 (No. 64) had not assumed the fully adult plumage which, at the time of 

 writing, I believed to be similar to that of the adult male.
