THE JACKSONIAN OOLOGICAL COLLECTION. 
CHESTNUT-RUMPED GROUND WREN, 
Hylacola pyrrhopygia, V. and H. 
Taken by A. F. Bassett. Hull, near Freshwater, Manly, Sydney, on 2nd August, 1902. Beautiful 
set of 3 eggs. This lively little bird I found plentiful in certain localities about Sydney, and succeeded 
in finding three of the nests. I saw them often in the bush between Freshwater and Dee Why, near 
Manly. They are shy, and keep themselves well hidden in the short dense vegetation, and suddenly 
they will often pop out, and then run along the ground very fast. The eggs are very dark, and some- 
what chocolate-coloured, and resemble, more than any others, some specimens of those of the Yellow- 
throated Scrub Wren (Serzcornis.) The nest is a dome-shaped structure, very loosely put together, 
and placed near the ground in some thickly-foliaged bush, or in long grass and weeds. Specimen A. 
measures in inches = 0°84 x 0°63. 
WHITE-THROATED THICKHEAD, 
Pachycephala gutturalis, Latham. 
Taken by Sid. W. Jackson, in Alipou Scrub, South Grafton, N.S.W., on 21st August, 1892. 
Beautiful set of 2 eggs. 
Taken in Alipou Scrub, South Grafton, N.S.W., by Frank and Sid. W. Jackson, on 1st November, 
1893. Beautiful set of 2 eggs. 
Taken by Sid. W. Jackson, at Booyong, near Lismore, N.S.W., on 18th November, 1899. Ground 
color of this set is white. Set of 2 eggs. 
Taken at Vinegar Hill Scrub, near Tyringham, 55 miles south-west of Grafton, N.S.W., by A. Boon 
and Sid. W. Jackson, on 23rd October, 1898. This is the most handsome set of these eggs I have ever 
seen, and being so heavily blotched resemble well marked specimens of those of the Harmonious 
Thrush. This lovely set of 3 completes the above series of the four differently marked sets displayed 
in the collection. I noticed that this bird utters quite a different note in the Richmond River scrubs, 
as compared with those found about Sydney. Specimen A. measures = 0°92 x 0°68. 
GREY-TAILED THICKHEAD, 
Pachycephala glaucura, Gould. 
Taken by M. W. Harrison, near Hobart, Tasmania, on 28th November, 1897. Beautiful set of 3 
eggs. 
BLACK-TAILED THICKHEAD, 
Pachycephala melanura, Gould. 
Taken at Bundaberg, Queensland, by T. Williams, on 7th December, 1899. Set of 3 eggs. 
I saw this bird in the Richmond River scrubs in 1899. Specimen A. measures = 0°94 x 0°66. 
OLIVE THICKHEAD, 
achycephala olivacea, V. and H. 
Taken at Sandford, Tasmania, by M. W. Harrison, on 24th November, 1897. Set of 2 eggs.
