THE JACKSONIAN OOLOGICAL COLLECTION, 
Set of 3 eggs, which are not nearly so well marked as those of the latter set. Taken by M. W. 
Harrison at Glenorchy, Tasmania, on the 27th of September, 1899. Specimen A. measures in inches 
= I'I3 x 0°87. 
GREY HARMONIOUS THRUSH, 
Collyriocincla harmonica, Latham, 
Very large set of 5 eggs, taken by Frank and Sid. W. Jackson, at Clarenza, South Grafton, N.S.W., 
on the 28th of August, 1892. The nest was placed only four feet from the ground, in the hollow 
portion of an Ironbark tree (Zucalyptus paniculata). Three to four eggs usually form the full comple- 
ment for a sitting, and five are very rarely found. The nests I have often found placed as high as 
seventy feet in the forests, and at Manly, near Sydney, I have frequently seen them built only a few 
feet from the ground ; they are constructed of bark and neatly lined with roots, and are placed in the 
thick fork of a tree, but I have discovered them more often in a hollow spout or limb. This species differs 
from many other of our Australian birds by reason of the sober colour of its plumage, which is incon- 
spicuous and little likely to attract attention, It is not a gregarious species, nor does it associate with 
other birds, living for the most part in couples, which presumably pair for life, and constantly keep 
together, subsisting upon the insects and other food to be found in the vicinity of the Eucalyptus 
forests, which are their favourite haunts. The note of this dainty creature is clear and harmonious, and 
loudly rings and re-echoes through the wattle-scented gullies of the forest. On a fine spring morning in 
August, when the birds are happily engaged at their nest building, it is almost impossible, even to the 
most disinterested, to avoid experiencing some delight in listening to these merry heralds of glorious 
bird life. I know a favourable time has then arrived, and I always hope, aided by the season, to turn 
the thoughts of others whose finer sympathies incline to nature’s wonders, and who enjoy listening to 
the history of some of the dainty living creatures around us, that so many greatly fail to under- 
stand and protect. There are occasions when bird life is thrust upon the casual notice of some of us, 
and periods when it is dormant, still many never give it a single thought ; and, though the scrubs and 
forests, and rank water courses shelter birds of a few hundred or more kinds, yet they are often passed 
by without any sign of curiosity or interest. Specimen A. measures = Lrg xs 07So; 
BROWN THRUSH, 
Collyriocincla brunnea, Gould. 
Set of 2 eggs, taken from a nest built in the thick upright fork of a dead tree in the Nicholson 
River district of north-west Queensland. Taken by E. Drew on the 19th of November, 189s. 
Specimen A. measures in inches = I'24 x o'82. 
BUFF-BELLIED THRUSH, 
Collyriocincla rufiventris, Gould. 
Set of 3 eggs, taken in the Blackwood River district, south-west Australia, by S. Hall, on the 31st 
of July, 1895. The eggs are very heavily blotched at the larger ends. Specimen A. measures in inches 
= 1°13 x o81. 
RUFOUS-BREASTED THRUSH, 
Pinarolestes rufigaster, Gould. 
Very handsomely blotched set of 3 eggs, taken by Sid. W. Jackson, in Alipou Scrub, South 
Grafton, Clarence River, N.S.W., on the 2nd of December, 1894. The nest was built in a labyrinth of 
vines and Scrub Cane (//agedlaria tnaica), situated 12 feet from the ground. I found these birds’ 
nests frequently built ina mass of Zanfana bush, growing over the tops of high stumps in the above 
scrub. They are, as a rule, very difficult to find, unless the birds are noticed going to or coming from 
them. Specimen A. of this fine clutch measures in inches = 1°03 x 0°77. 
Set of 3 eggs, which are pearly-white specimens and almost devoid of markings. ‘There is a great 
contrast between this and the previous set (No. 513), and a person not conversant with our oological 
studies would naturally consider this clutch as belonging to a distinct species. Specimens A. and B.
