upper part of the breast, and under tail-coverts bright yellow ; 

 abdomen and thighs white ; irides wood-brown ; bill dark 

 brown, becoming lighter at the edges of the mandibles ; legs 

 and feet greenish blue. 



The female differs from the male in being somewhat smaller 

 in size, and in having the throat green instead of black. 



Genus OREOICA, Gould. 



The only species known of this form is strictly Australian, 

 and is a sprightly animated bird frequenting the sterile districts 

 studded with large trees, where it hops about on the ground 

 in search of insects. Notwithstanding the singularly length- 

 ened form of its scapularies and its terrestrial habits, it appears 

 to me to partake of the characters of the ColluricinclcR and 

 the Pachi/cephaloB ; its loud piping note and mode of nidifica- 

 tion also favour this opinion. It lays three or four eggs in 

 a round cup-shaped nest, placed either in a Xanthorrhoea 

 or in a hole in the stump of a tree.
