262 Campbell, Additions to " H. L. White Collection." [isf April 



was intently watching me while listening to my " chirping," the 

 male was seen lurking in the dense foliage of a neighbouring bush, 

 but would not openly expose itself. A full-plumaged male is 

 usually accompanied by a party of from six to ten females and 

 young birds, and leads them away at high speed, necessitating 

 hard running to keep them in sight. One or two birds keep 

 dropping out of sight, and eventually one finds the whole party 

 has vanished in the scrub. The elusive males are even wilder 

 than those of M. cyanotus. The song of both species is very 

 similar — a delicate musical " trilling " — but not so frequently 

 uttered by the Black-and-White species. 



The birds usually run over the ground with tails erect at a 

 surprising speed, but they sometimes hop. They are very skilful 

 in flying perpendicularly into the air from the summit of a bush 

 and catching small insects on the wing. 



Stipiturus (malachurus) hartogi, Carter {Bull. B.O.C., xxxvii., 



p. 6 ; Ibis, 1917, pi. xi.) 



Whitlock secured a female of this newly-discovered, light- 

 coloured, insular form. Carter secured both sexes, which are 

 well figured in the coloured plate mentioned. It will be observed 

 that the Hartog Emu-Wren most resembles westernensis (Camp- 

 bell), but is smaller, paler, and has the filamentary feathers of its 

 tail broader. 



We learn from Mr. Carter that the first bird procured was a male, 

 which was creeping about in a small wattle-bush ; date, 28th April, 

 1916. At another part of the island, low, thick scrub matted with 

 creepers, and also patches of dwarf tea-tree, seemed full of these 

 extremely unobtrusive little birds. They creep about in a mouse- 

 like fashion, the only notes heard being a faint mouse-like squeak. 

 They do not fly much, but when they do the flight is straight, 

 with tail extended horizontally, and in the bright sunlight the 

 tail feathers sometimes glisten, so that these tiny birds might be 

 mistaken for large dragon-flies. By keeping quiet one can readily 

 watch them, and they can be " chirped " close up, but do not 

 come out much from the actual shelter of the bushes. The male 

 birds always appeared the bolder and more inquisitive. 



Mr. Carter states that the sub-species (hartogi) is " quite 

 distinct " from riificeps. May they not be separate species ? 

 (Compare Ibis, 1899, pi. vii., and Ibis, 1917, pi. xi.) 



Amytornis textilis, Quoy and Gaimard. Grass-Wren. 

 Diaphorillas t. textilis. 



Mr. Carter's second re-discovery (a single S) was this other 

 long-lost bird. Mr. Whitlock also obtained a single specimen, 

 fortunately the opposite sex. It was a fortunate " snapshot," 

 because it was the only specimen of the kind he saw on the Peron. 

 Therefore, after the lapse of a century, it took two good field 

 naturalists to collect a pair of birds, and so establish a long-lost 

 species.
