Mr. E. D. Atkinson of Tasmania, has forwarded a set of the 
eggs of this bird for description together with the following note: 
“ Mr. John Wright found a small colony of Ilerodias alba, breed¬ 
ing in a species of Eucalyptus, overhanging a river on the East 
coast of Tasmania, during 1883. The eggs I send you were from 
a nest containing four, one of which was unfortunately broken in 
transit.” The eggs vary considerably in shape, one specimen (A) 
is an elongated oval tapering slightly towards the smaller end, (B) 
is nearly a true oval in form, and (C) a swollen oval; they are 
of a delicate sea-green in colour, one specimen (B) having a slight 
limy covering on one side, giving the egg a blanched appearance. 
The surface of the shell is smooth and lustreless, but all have 
more or less minute indistinct shallow pittings. Length (A) 
213 x 1-43 inch; (B) 2-02 x 1-43 inch; (C) 1-95 x 1-48 inch.

“Coming home with cattle on the 25th May, 1890, my sons 
flushed a Duck of some sort off a nest in the grass too hurriedly 
to see what it was, they left it till next day when one of them 
rode out to identify the species, it proved to be a “ Whistler,’
