The upper surface is of a clear bluish grey, palest on the 

 sides of the head and darkest on the primaries, where the 

 grey of the mantle passes into deep slaty brown. This grey 

 tint is evidently that of the adult dress, some immature 

 feathers which remain amongst the primaries, secondaries, 

 and wing-coverts being of a much browner hue. In the 

 immature plumage, but not in the adult, the primaries and 

 the secondaries exhibit dark cross bars on the inner web; 

 these exist throughout the whole length of the secondaries 

 and on the basal portion of the primaries above the emargi- 

 nation ; the interspaces in the latter, and to a slighter extent 

 in the former, are tinged with pale fulvous brown. 



All the rectrices, except the two external pairs, belong to 

 the adult plumage, and are a pale grey, the central pair 

 being entirely free from bars and the others cross-barred on 

 the inner web only, and that somewhat indistinctly ; the four 

 external rectrices, which remain from the immature dress, are 

 brown, with distinct darker transverse bars on both webs. 



The throat is very indistinctly cross-barred with pale ful- 

 vous, alternating with grey and with white, the latter pre- 

 dominating; the remainder of the under surface of the body, 

 and also the under wing-coverts, is of an unbroken vinous 

 tint, only varied by slight and indistinct darker cross bars on 

 the basal portion of the feathers of the upper breast and by 

 similar but more distinct markings on the lowest feathers of 

 the under wing-coverts, the latter appearing to be the remains 

 of the immature dress ; also by some remains of immature 

 plumage along the central portion of the abdomen, consisting 

 of several white feathers with longitudinal central brown 

 marks more or less sagittate in form, the actual shaft of these 

 feathers being tinged with vinous.
