 salmon colour, with a zone of a deeper tint at the larger end, 

 and the wdiole freckled with minute spots of a still darker hue. 

 The stomach is diminutive and slightly muscular, the food 

 consisting of insects and honey. 



The sexes appear to present no difference in the colour of 

 their plumage ; but the female, as is the case with the other 

 members of the genus, is considerably smaller than her mate.

 yellow, approaching to grey on the back ; lores black ; ear- 

 coverts, throat, and under surface pale yellowish grey, faintly 

 striated with a darker tint ; behind the ear two tufts, the

 more spread over the sides of the neck, of a beatiful yellow ; 

 primaries and tail-feathers brown, margined with bright olive- 

 yellow ; irides very dark reddish brown ; bill black ; legs and

The only example of this new species that I have seen is 

 from the north coast of Australia, where it was procured and 

 subsequently presented to me by my friend Benjamin Bynoe, 

 Esq., late of Her Majesty's Surveying Ship the ' Beagle.' It 

 differs from all the other members of its genus in the uniform 

 yellow colouring of its plumage, for which reason I have 

 assigned to it the specific appellation oi flavescens. 



I regret to say that nothing w^iatever is at present known 

 of its habits or economy.
