THE JACKSONIAN OOLOGICAL COLLECTION. 
SPOTTED HARRIBER, 
Circus assimilis, J. and S. 
Clutch of 2 eggs, taken from alow Ti Tree (Melaleuca), near Ulmarra, Clarence River, N.S.W., 
on the 3rd October, 1896, by W. McEnerny and Sid. W. Jackson. Nest was only 25 feet from the 
ground, and was a frail structure lined with the paperbark and green leaves of the Ti Tree. This is 
the only nest and eggs I have found of this so-called Swamp Hawk, although we have noticed the 
bird a good deal about the Clarence River district. The eggs are white, and have a few nest stains, 
and measure as follows :—Specimen A. = 1°97 x 1°54; Specimen B. = 1°90 x 1'5r. 
SWAMP HAWKE, 
Circus gouldi, Bonaparte. 
This pair of eggs was taken near Somerville, Victoria, by G. Shepherd, on the 8th of November, 
1897. Nest was built on the ground amongst Scotch Thistles (Cavdmis lanceolatus.) Eggs white, and 
very slightly nest stained. Specimen A. measures in inches = 2°03 x 1°51. Specimen B. measures 
= iy) oo Tee 
BROWN HAWE, 
Hievacidea orientalis, Schlegel. 
Set of 2 eggs, taken from a Crow’s nest situated in the very bushy top of a tall Spotted Eucalypt 
(Eucalyptus maculata), near the Lake at the back of Swan Creek, Clarence River, N.S.W., on the 4th 
of September, 1895. This is the only clutch of these rust-colored eggs we have ever taken in the 
Clarence River district ; the bird is rather uncommon there. Taken by Frank and Sid. W. Jackson. 
We took a set of Crows’ eggs from this very identical nest during season 1894. (See data No. 590.) 
Specimen A. measures in inches = 2°08 x 1°52. Specimen B. measures = 1°97 X 1°52. 
Beautiful clutch of 3 eggs, taken by C. Ladwig at Werribee, Victoria, on the 6th of October, 1905. 
An average specimen of this set measures = 2°13 x 1°60. 
STRIPED BROWN HAWKE, 
Hievacidea berigora, V. and H. 
A very pretty clutch of 2 eggs, taken by F. E, Howe at Bacchus Marsh, Victoria, on the th 
October, 1904. The dark zone is on the pointed end of both these eggs, instead of at the thicker apex, 
and makes an interesting clutch on that account. Specimen A. measures = 2'07 x 1°55. Specimen 
B. measures 2°07 X 1°55.
