feathers, and placed on the ground at the bottom of a clump of 

 rushes or tussock grass. These birds have a strong perfume, and

 A white eyebrow; throat streaked with dark brown. Length 5.75 

 inches.

 buffy eyebrow; throat not streaked. Length 6.5 inches. 



The Striated Grass-bird, M. striatus. — West Australia (Lake Yanchep).

 genus. The long tail, short and rounded wings, and habits would indicate 

 its position as being nearest that group of birds frequenting sterile 

 situations with a sparse and stunted vegetation, among which are 

 included Amytis, Mylacola and Stipitiirus (North). Above rufous brown, 

 wings and tail dark-brown; lores and eyebrow whitish; throat dull white, 

 chest buff, breast and abdomen buffy-white. Length 5.65, wing 2.07, 

 central tail feathers 2.6 inches. The birds live on barren rocky ranges in 

 the dense spinifex tufts. 



Genus Origma. 

 With twelve tail feathers. Tail much shorter than the wing. 



The Rock-Warbler.
