ACANTHIZA ROBUSTIROSTRIS (Milligan), “Thiek-billed Tit.” 
Woongan Hills.; — Collector, A. W. Milligan. 
“The Emu,” vol. Ill, July 1903, page 71. 
Types. — (5546 and 5548) in Western Australian Museum, Perth. 
Acanthiza robustirostris belongs to that section of the genus in 
which the dark tail band occupies nearly the terminal half of the 
feather, and the base of the tail is bright colored like the rump and 
upper tail coverts. It was discovered in May, 1903, at Day Dawn, 
Murchison, by Mr. Frederick Lawson. The bill is remarkably robust 
for an Acanthiza. The general color of the upper surface is much 
more sombre than usual with this genus. The “scaling” or shell- 
marked feathers of the forehead, present in many members of the 
genus, are absent in this one. Above the rump is a conspicuous patch 
of white silky feathers, and the rump and upper tail coverts are snuff- 
colored, as also is the basal half of the tail. The sub-ocular and 
auricular regions are evenly and regularly “ rippled.” 
MEGALURUS STRIATUS (Milligan), Striated Grass-bird.— 
Lake Yanchep, miles north of Perth ; Dec., 1902. — Collector, 
A. W. Milligan. 
“The Emu,” April, 1903, Vol. II, part 4, page 201. 
Type. — (527 8) Male, in Western Australian Museum, Perth. 
The type specimen was shot at Lake Yanchep, 35 miles north of 
Perth, by Mr. A. W. Milligan, in December 1902. It was compared 
with specimens of Mtgalurus gramineus from Victoria and Mandurah 
Estuary, some 40 miles south of Perth. Little difference exists between 
the Victorian and Mandurah skins. On the other hand, the difference 
between those skins and the Lake Yanchep skin is most marked. The 
latter is very much smaller and in addition, lacks the fulvous color of 
the upper surface, sides, flanks, and tail coverts of the former, and in 
lieu, has these of a dullish, lustreless smoky-brown. 
The notes of the new bird are two melancholy ones, resembling 
in sound the syllables “tee tee.” In the protected area of the Swan 
River, in Perth, the local bird has three notes — “titty tee tee.” The 
birds were numerous, but difficult to flush owing to their secretive 
habits.
