For the first eggs of this species, I am indebted to my friend 
Mr. Charles Mayo, of Childers, South Clippsland, who obtained 
them during October 1878. The nest, he informs me, was built 
in a mountain musk (Olearia argophylla), and was similar to that, 
of P. (jutturolis, (which is common in that district) but larger and 
more compactly built. The egg is pointed at both ends, swelling 
heavily near the centre, the ground colour being butty-white, 
marked all over, but particularly on its thicker end with dots 
and spots, of reddish and blackish-brown, intermingled with a few 
here and there of umber, while appearing as if beneath the surface 
of the shell are larger spots and blotches of dark lilac, which in 
some places are confluent, and form an irregular zone. Length 
1-07 inch x 1*78 inch. 
A pair taken in the New England district, (N.S.W.) have the 
markings more evenly dispersed over the surface, and measure as 
follows : — (A) 1-08 inch x 1*76 inch ; (B) P09 inch x P77 inch. 
Two eggs are the usual number for a sitting, and the breeding 
season commences in September and lasts throughout the three 
following months.
