68 MATHEWS— Birch of North and North-West Australia. 



both in construction, material, and situation to the nests of 

 the common bird; the note is also distinct, but the bird itself 

 requires a close inspection to distinguish it. The most 

 marked difference is the absence in ewingii of the pale freckled 

 marks on the forehead, and the more rufous crown of the head. 

 Two of the nests contained young, one was empty, and one con- 

 tained four fresh eggs, three of which are sprinkled with red- 

 dish spots chiefly at the large end, and one egg was quite white. 

 The male bird and eggs are in my collection, and the nest ini 

 the S.A. Museum. The birds with young were not interfered 

 with. 



In the neighbourhood of Latrobe most, if not all, the com- 

 moner scrub birds of Tasmania were noted. Specimens of the 

 North Tasmanian Blue Wren, Malurns cyaneus fletcherae, Mat., 

 were secured, but on comparison with skins taken by myself 

 in the .south part of the island, I can find no difference, 

 although Mr. Mathews separates the two into separate sub- 

 species. Dates of nests referred to as under: — 



7/10/16. — Sericornis humilis, Lake Sorell. 



8/10/16. — Pozanoidea plumbea immaculata, Mat., Scottsdale. 



27/9/16. — Cinclosoma punctatum dovei, Mat., Hobart. 



10/10/16. — Tribonyx mortieri, Latrobe.
