GENUS COLLURICINCLA (Vig. and Horsf.) 



EACH part of Australia possesses at least one species of this form, which both in structure and 

 habits is a medium between the Shrikes and Thrushes. 



COLLURICINCLA HARMONICA. 



HARMONIOUS SHRIKE-THRUSH. 



NEW SOUTH WALES, Victoria, and South Australia constitute the home of this species, which was 

 first mentioned by Latham. 



It is found in all parts of these colonies, both in the plains and large forests, and in the 

 dense brushes and thickets near the coast. In habits it is chiefly arboreal, obtaining the greater portion 

 of its food among the branches of trees. It subsists principally on insects, but seeds and berries also 

 form part of its food. 



Its song, which is continually uttered whilst feeding, is very musical, consisting of loud notes 

 several times repeated. 



The nest, which is made of bark, roots, and sometimes leaves and wool, is placed either in 

 a hole in the trunk of a decayed tree, or on the ledge of a rock. Three eggs are laid, the ground colour 

 of which is white, slightly tinged with grey, and spotted and blotched with reddish-brown and bluish- 

 grey. Their length is one inch and two lines, and the breadth ten lines. 



There is no material difference in the plumage of the sexes. 



The ear-coverts arc brownish-grey ; upper surface and wings, dark brown, the wing feathers 

 margined with black ; tail, grey, with dark brown shafts ; under surface, light greyish-white, each of 

 the feathers of the throat and chest having a dark line down the centre ; irides, brownish-red ; bill, 

 logs, and feet, black. 



Habitats : New South Wales, Victoria, and South Australia. 



COLLURICINCLA RUFIVENTRIS (Gould). 



BUFF-BELLIED SHRIKE-THRUSH. 



THE Colluricincla Rufiventris, which inhabits Western Australia, bears a strong resemblance to 

 Colluricincla Harmonica, but on closer examination many points of difference are found. It 

 frequents principally brushes and other places thickly covered with timber. 



Its habits and food are the same as those of its eastern representative.
