assume the plumage of the female, then this may be one ; but I think 

 it much more likely that the collector, in labelling a number of skins, 

 has made a mistake in the sign of the sex. One might expect to find 

 the young of both sexes alike, but 1 have never seen a young male 

 in any other than the black plumage with white throat-spot. In 

 this dress the middle of the breast and the abdomen are white, with 

 the slightest yellow tinge on the breast, and these parts are similar 

 to those of the young female ; therefore Mr. Eichardson's c? cannot 

 he a bird intermediate between the brown-plum aged male (if it exist) 

 and the black-plumaged bird with white throat-spot, because his 

 specimen is almost a counterpart of the adult female, having the 

 middle of the lower breast and abdomen brilliant lemon-yellow, and 

 the black chest-patch, although less developed, glossed with greenish 

 blue. I should not be surprised to find that the young male does 

 not resemble the young female ; the specimens in black plumage with 

 white throat-spot appear to be ver)/ young birds, they may, how- 

 ever, have passed through the first autumn moult. Further inves- 

 tigations will clear up this point. 



Specimen p', J ad., has one or two of the feathers comprising the 

 brown throat-spot tipped with pale scarlet.
