time, robbing the rare nests of the Snake-necked Darter (Plotus nove-hollandie.) We have taken five 
sets of Coucals eggs in the Clarence River district. These eggs I find have always a thin coating of 
lime over them, the shell beneath being of a pure white. The note of this bird is very like the distant 
bark of a dog, and is kept up each time for about twelve seconds, and graduating from low to high 
notes, and vice versa. Specimen A. measures = 1°45 X 1°11, Specimen B. measures = 1°45 X I'I4. 
Specimen C, measures = 1°40 x 1'06. 
DOLLAR BIRD, 
Eurystomus australis, Swainson. 
This beautiful clutch of 4 eggs was taken by W. McEnerny and Frank and Sid. W. Jackson, on 
13th November, 1897. Nest was placed in a hollow spout of a giant Eucalypt, near Alipou Scrub, 
South Grafton, N.S.W., and at an altitude of over 90 feet. We have found many of these nests in 
years past, and took several sets of the eggs, but the birds generally build in such dangerous positions 
that it often renders it impossible for any person to get within arms reach of the nest. With us in 
Australia this bird usually puts in its appearance after a storm, during the early part of October, and 
departs again very often with a storm in February. During the recent visit of the Japanese warships 
to Sydney (1906), one of the officers 
informed me that these Dollar Birds 
are often to be seen in thousands 
on some of the mountains in Japan, 
and no doubt all our birds migrate 
there. Each season they seem to 
be getting more numerous with us 
here, yet, nevertheless, their eggs 
are hard to get, and that is simply 
because they select such very tall 
and inaccessible trees to nest in. I 
find that a very good imitation of 
the note of this bird can be produced 
by rolling together, on a sheet of 
wadding, two of their eggs (blown), 
and at the same time gently knock- 
ing them against each other. I found 
it out quite accidentally as I was 
busily engaged arranging the eggs in

found, usually formed the sitting, and 
not four. ‘They are minutely pitted 
all over. Specimen A. measures = 1°33 x 1'07. Specimen B. measures = 1°33 x 1°06. Specimen

SPINE-TAILED LOG RUNNER, 
Orthonyx spinicauda, Temminck. 
This is an interesting set of 2 eggs, on account of them having been taken from the nest close to 
that of the Afvichia vufescens. (See illustration of the nest in A. J. Campbell’s book, page 252.) Taken 
by Sid. W. Jackson and party, at Bulabulah Creek, in the Don Dorrigo Scrubs of the Upper Bellinger 
River district of N.S.W., on 20th October, 1898. We have found over thirty of the nests, and have 
taken upwards of ten sets of these eggs in the northern scrubs of N.S.W., and they have always appeared 
to me as being very large for such a small bird. The eggs are now becoming very rare. The nests of 
this species are dome-shaped, with an entrance at the side, and are chiefly constructed of green moss,
