Plate XXV. 



Fig. 1. Cooper Creek, near Cuttapirie Corner. 



Fig. 2. On the Cooper. The larger timber is the home of 

 large flocks of naked-eyed cockatoos (Cacatua gxjmnopis). An 

 eagle had built its nest in the tree in mid-stream. 



Plate XXVT. 



Fig. 1. Nest of wedge-tailed eagle (U rectus audax). Owing 

 to the scarcity and dwarf character of the timber, this large eagle 

 builds its nest within reach of a man on camel back. 



Fig. 2. Tree near Kanowana, with nest of galah (Cacatua 

 roseicapilla) in the "spout.'' The tree had been ring-barked by 

 the cockatoos, and as nesting sites are very scarce in the district 

 it might almost appear that the birds had purposely ringed the 

 trees (several of which were found similarly treated) in order to 

 increase the accommodation ; though this is perhaps too much to 

 suggest for the intelligence of even a cockatoo. 



Plate XXVII. 



Fig. 1. Descending a. sandhill preparatory to crossing a 

 gibber plain, across which another sandhill will be encountered. 

 When near Perigundi seventeen such sandhills were crossed 

 between sunrise and sunset. 



Fig. 2. A woma (Aspidites ramsayi. Macleay) obtained 

 near Perigundi. Although tracks of this large python were often 

 seen, this was the only example secured. 



Plate XXVIII. 



Fig. 1. Mungeranie Bore, October 15, 1916. The rising 

 steam was a gratifying sight in the early morning, after a period 

 of several days of privation. This bore supplies the stream seen 

 in fig. 2 of this plate. 



Fig. 2. Mungeranie Creek, supplied by the bore. Our camp 

 and the constable's enclosure are seen on the further bank. 



Plate XXIX. 



Fig. 1. Outflow of the Cannmvaukaninna Bore, photographed 

 October 18, 1916. Water was struck only a few days before our 

 arrival, the depth being 3,740 feet, and the flow 500,000 gallons 

 daily. 



Fig. 2. Our team of nine camels, near Wells Creek, October 

 23, 1916. The water lying on the ground is the result of 135 

 points of rain which fell the previous night. 



Plate XXX. 



A mirage drawn by Mr. G. A. Barnes from rough sketches 

 and descriptions supplied by Mr. Edgar R. Waite. 



Fig. 1. The view as seen under natural conditions. 



Fig. 2. As it appeared under the influence of the mirage. 



Plate XXXI. 



Fig. 1. Nest and eggs of black-faced wood swallow (Austr- 

 artamus mclanops). 



Fig. 2. Nest and eggs of pied honey-eater (Certhionyx 

 variegatus).
