458 Mr. W. R. Ogilvie Grant on the 



Koch^ the Director of the Darmstadt Museum, and the col- 

 lector's name, through whom the original type specimen was 

 obtained, should be written Herr v. Othberg, not Oothberg. 



The type was borroAved by Lord Tweeddale and figured 

 by Mr. J. Smit in the P. Z. S. 1878, pi. xxiv. This figure 

 is also very inaccurate, for though the dark olive of the 

 upper parts is represented (though much too bright), the 

 wing is here shown as almost uniform olive-green, with two 

 slate-blue cross-bands formed by the tips of the secondary 

 and greater wing-coverts; this is quite inaccurate ; in both 

 Gould's and Elliot's figures these parts of the bird are 

 correctly figured. On comparing these three plates, it is 

 curious to see how remarkably they diflPer one from another 

 considering that they are all supposed to represent the same 

 individual. 



As M. Oustalet's description of the immature bird in the 

 Paris Museum does not seem to agree with any of the stages 

 of plumage shown in the series before me, the following 

 description may be useful : — 



Immature female. Top of the head rather dark brown, 

 shading gradually into a more rufous tint on the nape ; all 

 the feathers have rather darker margins, giving these parts 

 a slightly scaled appearance ; a few of the dull red feathers 

 of the adult are beginning to make their appearance ; the 

 dark olive on the rest of the upper parts has a somewhat 

 browner shade, though here and there some of the greener 

 feathers of the adult plumage may be seen; the greyish 

 blue of the outer wing-coverts and outer webs of the 

 secondaries is replaced by dull olive, and the slate-blue 

 of the upper tail- coverts and tail is not so bright ; the ear- 

 coverts are brown, with buft' centres ; the moustache stripes 

 dirty white, devoid of that reddish shade characteristic 

 of the adult plumage ; the chin and throat-feathers with 

 white centres and black margins and bases, those on the fore- 

 neck being conspicuously white, washed with reddish ; the 

 chest-feathers are whitish bufi", edged with brownish buff, 

 with here and there a few slate-blue feathers ; rest of the 

 underparts dirty whitish bufl', most of the feathers, especially
