 Family SILVIIDAE. 



ACANTHIZA IREDALEI MORGANI, Mathews 



(Southern Tliin-billed Tit). 



During the early part of the journey a small party of 

 these birds was met with, moving about in a very sprightly 

 manner amongst the low bushes in a dry water-course, 

 searching stem and leaf for insect food. They were not 

 again seen. 



Pyrrholaemus brunneus, Gould (Redthroat). 



I have not visited any part of the interior where this 

 bird is not to be found. They were not plentiful in the 

 country we passed through, but at times their sweet song 

 enlivened, the wilderness, for it was often poured forth in the 

 mornings and evenings from the top of a bush or dry twig. 



Total length. Expanse of wings. 



September 13 $ 150 mm. 186 mm. 



Hallornis cyanotus, Gould (White-winged Wren). 



This was a very common bird throughout the saltbush 

 country. Like some of the Mahiri the male is very conscious 

 of his bright plumage, and will keep out of sight as much 

 as possible, while the brown females and immature males hop 

 round in full view, the full-plumaged males having slipped 

 away close to the ground, and they are next seen flying 

 to cover some distance off. This will be repeated many times 

 if the birds be followed up. 



Total length. Expanse of wings.

Leggeornis lamberti assimilis, North 



(Purple-backed W T ren). 



Only twice were these birds met with, and each time a 

 small party was seen in Old Man Saltbush (Atriplex 

 nummularia). Upon comparison with birds nearer the coast 

 little or no variation can be found.
