for several days to secure them, but without success; all sorts of 
schemes were frustrated by their watchfulness. I have myself lain 
in ambush for half a day, covered up almost with branches of trees, 
without seeing a sign of one, but no sooner would I leave, than one 
would swoop down from some spot where it had hitherto been con- 
cealed, and after staying a minute to quench its thirst, would dart 
off again as quickly as it came. Our patience was rewarded finally 
though, as one evening one was shot amidst great rejoicing. It 
proved to be a fine specimen, its white head, throat, and breast, 
showing out in strong contrast to the dark chocolate colour of the 
wings and back. The feathers are soft and silky to the touch, and 
are greatly sought after for the manufacture of artificial flies for 
fishing. This was the only one we succeeded in getting, although 
we tried hard for them during the remainder of our stay. We got 
nothing more of importance at the dam, so at the end of a week 
from time of getting there, again struck tent, and returned to 
Stewart’s Creek, where we camped within half a mile of the spot 
we first chose on reaching the bush, intending to wait there until 
the arrival of Mr. A. J. Campbell, a gentleman well-known to most 
of you, who had resolved to spend a month or two with us in North 
Queensland.

GEOLOGICAL SKETCH OF SOUTH-WESTERN 
VICTORIA. 
By Mr. J. Dennant, Hamitton. 
(Read before Field Naturalists’ Club of Victoria, 14th Dec., 1885) 
Parr Il. Upper Patanrozoirc Rocks. 
A CONSIDERABLE area of ground is occupied by these rocks, but their 
principal development is to the eastward, where they form extensive 
mountain chains. As the traveller approaches Dunkeld from the 
east, he sees the rugged outlines of the Serra Range, culminating in 
the peaks of Mounts Abrupt and Sturgeon, the first of which 
reaches a height of 2724 feet. From these peaks on the south, the 
range extends in a north easterly direction, till it junctions with the 
Grampians proper at Mt. William, 3827 feet high, being serrated 
in a most regular manner for the whole distance, about thirty 
miles. Going through the most southerly pass in the range, with 
Sturgeon and Abrupt on either hand, another range, the Victoria, 
is seen, nearly parallel with the Serra, an extensive valley of almost 
flat country lying between. This range extends in a generally 
north and north easterly direction for over thirty miles, as far as 
the banks of the Glenelg. North of this river, however, though 
much farther to the west, is the Black Range, which maintains
