THE JACKSONIAN OOLOGICAL COLLECTION. 
Set of 3 eggs, which are quite differently marked to those of the latter set, and resemble very much 
the eggs of the Grey Butcher Bird (Cvacticus destructor). Taken by A. Amos, D. Hawthorne, and 
Frank T. A. Jackson, at South Grafton, N.S.W., on the 2nd of December, 1894. The nest was built 
in a Red Cedar tree (Cedvela australis), at an altitude of 39 feet. Specimen A. measures = 1°25 x 0°87. 
YELLOW-BELLIED FIG BIRD, 
Sphecotheres flaviventris, Gould. 
Set of 3 eggs, which are of the very pale green variety, and are heavily blotched. Like the latter 
species, the eggs of this bird vary considerably in their ground colouring and markings. Taken by 
H. Barnard, at Cape York, Queensland, on the 7th of November, 1896. Specimen A. measures = 
1°26) x 0°78: 
Set of 3 eggs, which are of the salmon-colour variety, being heavily blotched, and quite unlike the 
latter set. It was taken, in the Bloomfield River district of North Queensland, by a collector engaged 
by C. French, jnr., on the 27th of November, 1895., I have seen these birds as far south as Grafton, 
N.S.W., in January of 1896, and at Byron Bay, N.S.W., in January of 1900. Specimen A. measures 
— el 22 LO). 
ORIOLE, 
Orviolus viridis, Latham, 
Handsome and very elongated clutch of 2 eggs, with a very light ground colour. Their shape is 
peculiar, because, although long, they are blunt and rounded at each end. Taken on the 27th of 
November, 1892, at Yellow Gully, South Grafton, N.S.W., by Jas. Neale, Frank and Sid. W. Jackson. 
The nest was a beautiful structure, and was placed in a Mahogany tree (Eucalyptus vobusta) at an 
altitude of 26 feet. It resembles very much that of the Leather Head, but is often much more neatly 
constructed. This species confines itself to the trees growing near water courses. Specimen A. 
measures in inches = 1°53 x 0°88. 
This is the historical set of 3 eggs with which the first authenticated egg of the Koel Cuckoo 
(Eudynamis cyanocephala) was taken. Specimen A. of the clutch measures in inches = 1°40 x I’OT. 
For my notes see also A. J. Campbell's book, pages 82 and 587, and illustration ; also, coloured figure 
on plate 17. The eggs of this set are much shorter and stouter specimens compared with those of 
clutch No. 543, and the ground colour is of a very much darker cream. On the afternoon of the 31st 
of October, 1894, I left South Grafton and went into the bush, in hopes of securing some special beetles 
of the Cavabide family, for a friend collector, but before I had gone very far my attention was directed 
to a pair of Koels (g¢ and ?), by the great noise they were making in the gully. I went over and 
noticed the birds fly from a Forest Apple tree (Angophorva subvelutina) into another beside it, and found 
the female Koel on a limb near an Oriole’s nest. This looked to me suspicious, and at the same time 
very encouraging, so I climbed up and carefully “ mirrored” the nest, and found it to contain only 3 
eggs of the Oriole. I came down again and rested in the shade, and with an anxious mind and palpi- 
tating heart, watched the female Koel as she chased the Orioles. Shortly the male Koel flew away, 
and the female went on the Oriole’s nest. I did not move, although I was most uncomfortable through 
the cramped way in which I was sitting, and after waiting for fifteen minutes, I got up and hit the tree 
to frighten the Koel off the nest, but she would not go. I then felt thoroughly convinced she was 
laying, and that my patience would be rewarded ; so after fully another fifteen or twenty minutes, I got 
up and hit the tree again, this time with a tomahawk, and in a few seconds off she flew, accompanied 
by the male, who had returned in the meantime. I was quite delighted at this, and once more climbed 
the tree, and found the nest contained four eggs—three of the Oriole, and one of the Koel Cuckoo. 
In scooping the eggs from the nest, the Koel’s egg got a little dented on the side, but has since been 
successfully repaired. See accompanying illustrations, pages 100, ror. The three Oriole’s eggs measure— 
Specimen A. = 1°40 x ror; Specimen B. = 1°34 x 0°97; Specimen C. = 1°39 x vor. The 
Koel’s egg measures = 1°36 X 1°02,
