THE JACKSONIAN OOLOGICAL COLLECTION. 
your attention. They are also familiarly known in some localities as Rain or Flood Birds, for their 
presence is supposed to be a sure indication of much rain. The birds arrived in great numbers in the 
Clarence River district during December of 1892, and Strange to say a few weeks later the locality was 
visited by a most disastrous flood, which I witnessed. John Welsh, of South Grafton, informed me 
several years ago that while he was in the scrubs at Cangi, in the Upper Clarence River district, engaged 
in the cutting of Cedar, he had many opportunities of watching these Channel Bill Cuckoos, and has 
often seen the Pied Crow Shrikes (Strepeva graculina) feeding the young of this Cuckoo in its nest. 
The eggs of these Channel Bills are not unlike those of the Pied Crow Shrikes. 
BLACK-BACKED MAGPIB, 
Gymnorhina tibicen, Latham. 
(Variety A).—Set of 4 most extraordinary looking eggs, on account of their very elongated form. 
Taken by Frank and Sid. W. Jackson, near South Grafton, N.S.W., on the 23rd of September, 1894. 
Specimen A. measures = 1°92 x 1°07. 
(Variety B.).—Set of 3 eggs, which are of a very rare form of ground colouring and markings. 
They are a pale bluish-white, with round spots of deep reddish-brown sparingly scattered over the shell. 
Taken by Frank and Sid. W. Jackson at South Grafton, on the 7th of October, 1894. Specimen A., 
which has very few spots on it, measures in inches = 1°57 x 1°07. 
(Variety C.)—Set of 3 eggs, of a stone-grey colour, zoned or capped at larger ends with dark 
markings. Taken by Frank and Sid. W. Jackson at South Grafton, on the 23rd of September, 1894. 
Specimen A. measures = 1°66 x 1°13. 
(Variety D.)—Set of 3, which very much resemble Crows’ eggs. Taken at South Grafton by Frank 
and Sid. W. Jackson, on the goth of October, 1893. Specimen A. measures = 1°60 x Tale 
(Variety E.)—Set of 3 eggs, which resemble those of the Pied Crow Shrike. Taken at South 
Grafton by Frank and Sid. W. Jackson, on the 16th of September, 1892. Specimen A. measures = 
ny Re wee 
(Variety F.)—Magnificent set of 4 eggs, which are of a pale apple-green ground, with large blotches 
(not streaks) of reddish-brown. This is the best marked set I have ever seen. Taken by Frank and 
Sid. W. Jackson at South Grafton, on the 3oth of September, 1894. Specimen A. measures = I'50 
x 1°07. 
(Variety G.)—Set of 2 eggs, which are a very remarkable and rare variety, and altogether different 
to the latter set. The ground colour is a reddish-chocolate without markings. Taken near South 
Grafton, N.S.W., by Frank and Sid. W. Jackson, on the roth of September, 1893. In the construction 
of the nest, from which the above two eggs were taken, several long pieces of barbed wire were 
used. Specimen A. measures = 1°50 x 1°06. 
(Variety H.)—Set of 2 eggs, which are of the more usual and typical form, and were taken at Swan 
Creek, near South Grafton, N.S.W., by Frank and Sid. W. Jackson, on the 16th of September, 1892. 
Specimen A. measures = 1°57 x 1°17. This concludes the fine series of this Magpie’s eggs in the 
collection, and it is truly wonderful what a number of very distinct forms may be found in the ground 
colouring, and the general disposition of their markings. 
TASMANIAN MAGPIE, 
Gymnorhina hyperleuca, Gould. 
Set of 2 eggs, taken by C. R. Porter, at Campbelltown, Tasmania, on the 16th of August, 1896.

beautiful richly marked clutch, and was taken by a timber getter and sent through the post “ unblown,” 
but arrived safely. Specimen A. measures = 1°67 x 1°13.
