[* Latham's Synopsis, vol.iv.

pl.53.] The disposition of the blue is found to differ in most of the specimens.
In the present variety, the whole head is enveloped in blue, which terminates in an irregularly waving line, and is continued below the eye in a broad band, edged in the same manner, and running almost to a point, as low as the bottom of the neck on each side; but there is no band continued round the neck, which, both above and below, is of the deep blue like velvet, mentioned by Mr.Latham.Some feathers of a very bright orange lie immediately under that blue, and above the wings*.
[* The Specimens from which Mr.Latham took his descriptions were met with at Van Diemen's Land, the most southern part of New Holland.] SUPERB WARBLER, Female.
When Mr.Latham's Synopsis was published, the female of this species was entirely unknown; and it was conjectured by that author that the disposition of the blue might possibly mark the sexes.

The female is now discovered to be entirely destitute of all the fine blue colours, both pale and dark, by which the male is adorned, except that there is a very narrow circle of azure round each eye, apparently on the skin only: all the upper feathers consist of shades of brown, and the whole throat and belly is pure white.

Except from the shape and size, this bird would not be suspected at first sight to belong to the same species as the male: the epithet of superb applies very ill to the female.
