620 584 6 NATIVE HEN, 
Tribonyx mortieri, Du Bus. 
Beautiful set of 6 eggs, taken by M. W. Harrison, on the 15th of November, 1894, on Wilson's 
Swamp, New Norfolk Road, Tasmania. Specimen A. measures = 2°22 1°52. 
‘The Podiceps,'’ the canoe used while nesting on the Clarence River Swamps of New South Wales. 
621 585 2 BLACK-TAILED NATIVE HEN, 
Microtribonyx ventralis, Gould. 
Pair of eggs, taken by J. T. Gillespie in the Riverina, Victoria, on the roth of October, 1887. 
Specimen A. measures = 1°85 x 1°27. 
622 587 2 BLUE BALD COOT, 
orphyvio bellus, Gould. 
Fine pair of eggs, taken by S. Hall, near Lake Muir, South-west Australia, on the 1st of January, 
1896. Specimen A. measures = 2°17 x 1°46. 
623 589 4 Coot, 
Fulica australis, Gould. 
Set of 4 eggs, taken by Frank and Sid. W. Jackson on the roth of November, 1895. The nest 
was built in rushes on the edge of a small creek, six miles from South Grafton, N.S.W. Although these 
birds frequent the swamps and creeks of the Clarence River district in thousands, yet their nests are 
very rare and hard to find. The above set of eggs is the only one we took during our long residence in 
the district. I think most of these birds go out west to breed. Specimen A. measures = 1°98 x 1°40. 
This is a beautiful set of 7 eggs. Taken by J. Watson at Buckiinguy Station, Western New South 
Wales, on the 2nd of November, 1903. Specimen A. measures = 2°0f x 1°33.

625 586 It BLACK MOOR HEN, 
Gallinula tenebrosa, Gould. 
A very large set of rr eggs, taken by Sid. W. Jackson, on a swamp near Lavadia, at the Lake, six 
miles from South Grafton, N.S.W., on the 28th of August, 1898. While I was up at the nests of the 
Little Black and White Cormorants, in a Swamp Mahogany tree (Eucalyptus robusta), I saw this set of 
eggs in a nest beneath me, among the rushes, and waited for the bird’s return before I robbed it. This 
set of eggs had incubation about seven days old, but were nevertheless easily emptied. Two of the 
eggs (specimens J. and K.) are quite differently marked to the others, and probably two birds of the 
same species laid in the one nest. Specimen A. measures = 1°93 x 1°42. The Litttle Black and 
White Cormorants’ nests in the Mahogany tree were hardly finished being built, and on September 11th 
of the same year (1898), we had an extensive taking of their eggs, in addition to those of the Little 
Black Cormorant and the Snake-necked Darter. (See data Nos. 307, 308, 310).
