^"'.92^^'] ^ViiiTE, Rufous Scrub-Bird and Olive Thickhead. I95 



traco of the rufous uudcr-colouiing : while another immature 

 bird (male), about eight weeks old, has almost adult plumage 

 except that the outer w^ebs or edgings to the wings are dark 

 chestnut-brown and not cross-barred, as m the full adult. As Mr. 

 Jackson, in this issue, has furnished the dimensions, details, flesh 

 parts, (S:c., there is no need to recapitulate same here. 



Regarding the Olive Thickhead (Pachycephala olivacca mac- 

 phersonianus), mentioned in the same Emu, p. 273, and described 

 from a single specimen, a mated pair obtained by Mr. Jackson 

 confirms this northern sub-species, and that the t^'pe skin was a 

 male. 



Male. — Lighter-coloured generally, and more greyish (slate-grey) 

 about the head than southern form ; a distinct mottled white 

 throat is succeeded by a greyish band on the breast, which breaks 

 into a tawny olive or buckhorn-brown under surface. Eyes 

 reddish-brown ; feet silvery-grey ; legs brownish ; bill blackish- 

 horn. Dimensions in mm. : — Length 2uq, wing 100, tail 95, 

 tarsus 26, culmen 22. 



Female. — Differs from male in the absence of the greyish head 

 and breast band, but has the mottled white throat. Eyes coffee 

 brown ; legs and feet silver-grey ; bill — upper mandible blackish- 

 horn, lower mandible much lighter coloured. Dimensions : — 

 Length 213, wing 102, tail 98, tarsus 30, culmen 22. 



Second Trip to Macpherson Range, South-East 

 Queensland. 



By Sidney William Jackson, R.A.O.U., Belltrees, Scone, 



N.S.W. 

 September 2()th, 1920, found me engaged putting up camp again 

 in the luxuriant and wonderful jungles on top of the Macpherson 

 Range, in south-east Queensland, where success had favoured 

 me when collecting the first known female specimen of the Rufous 

 Scrub-Bird [Atrichornis rufescens) in 1919, as recorded in The Emu 

 (vol. xix., part 4). 



The camp was situated at an altitude of nearly 3,500 feet above 

 sea-level — several hundred feet higher than the previous camp. 

 At this elevation, and within less than 30 miles of the ocean, the 

 camp was frequently enveloped in clouds and mist, especially 

 after a warm day. Often it would rain all day about the camp, 

 yet not much over 1,500 feet below often not a drop fell. The 

 days were mostly warm, but pleasant, and the nights rather cold, 

 except early in December, w^hen they were sometimes warm and 

 sultry. Many severe cyclonic storms, accompanied by heavy 

 rain and hail, occurred during October and November, doing 

 much damage in the great tall scrub or jungle, as well as smashing 

 and destroying rare nests and eggs of birds which were under 

 observation. However, perfect specimens were found later.
