P(ECILODEYAS SUPEKCILIOSA (Gould). 



WHITE-E YEBRO WED ROBIN. 



OF this species, first discovered by Gilbert in the north part of Queensland, very little is known 

 beyond the fact that it inhabits dense scrub bordering the rivers in that region, particularly 

 the Burdekin. 



Its shyness of disposition leads it to frequent the thickest part of the scrub, and it is 

 therefore very little seen. Like the Petroicw it carries its tail erect. 



A stripe across the forehead and over the eye, the throat, lower part of abdomen, and the 

 bases of the primaries and the secondaries are white ; lores, ear-coverts, and primaries and secondaries, 

 brownish-black ; remaining wing-feathers, upper surface and tail, dark brown ; chest and part of 

 abdomen, light grey ; irides, reddish-brown ; bill, legs and feet, black. 



Total length, 5 inches ; bill, f inch ; wing, 3 inches ; tail, 2\ inches ; tarsi, ^ inch. 



Habitat : North-eastern part of Australia. 



GENUS AMAURODRYAS (Gould). 



r jlHE single member of this form differs considerably in the style of colouring from the Petroicm. 



AMAURODRYAS YITTATA. 



DUSKY ROB1X. 



rpHE exclusive home of this bird is Tasmania, the situations most frequented by it being places thinly 

 J- timbered and covered with thickets and stunted growth of all kinds. It has not been found 

 on the continent of Australia. Like the Pctroica Multicolor it is very often seen in the vicinity of 

 dwellings, its taineness making it a great favourite. 



While procuring from the branches of small trees the insects on which it lives, it utters a 

 low monotonous note. 



The site usually chosen for its nest is a ledge of a rock, or some other sheltered place. 

 The structure itself is cup-shaped, and is built of roots, small sticks and grass, lined with wool or 

 fur. Three, and sometimes four eggs are laid, ten lines long and seven and a half lines broad. In 

 colour they are light greenish-blue, speckled with dark brown. 



The sexes do not differ in outward appearance.
