This new species of Tiirnix is allied to T. ve/ox and T. pyrj-hothorax, 
but the almost uniform white under surface will .serve to distinguish it from either, 
and from any member of the genus yet discovered in Australia. 
Three newly-hatched young in the down, obtained at “ Hell’s Gate,” are 
probably I’eferable to this species. 
[Great numbers of these birds were found throughout the grass country north 
of Charlotte Waters. At Illaniurta, on 30th May, a clutch of hai’d-set eggs 
were found, and afterwards young birds were frequently picked up. At 
Petermann Creek half-grown young ones ran about our camp. Wherever grass 
was plentiful, particularly near Heavitree Gap and on Missionary Plain, they 
were also numerous. Whilst crossing the latter country, my attention was called 
to a dingo hunting in the grass like a setter dog. Presently he made a decided 
set, and then suddenly springing forward, flushed a brace of these birds, one of 
which he caught in his mouth and soon swallowed. He soon started after the 
second one, and as he was approaching his bird, hunting keenly, he permitted me 
to get near enough to stop his quail-hunting. He was a line male dingo, but black 
in colour.] 
A set of the eggs of this species since received from Mr. Keartland, and taken 
at Illamurta, Central Australia, on the 18th June, 1895, are of a buffy-white 
ground colour, minutely freckled and sparingly spotted with diflerent shades of 
chestnut-brown, purplish-brown, and violet-grey. Length (A) 0'93 inch x Off 
inch; (B) 0-88 inch x 0ff3 inch; (C) 0-9 inch x Off inch; (D) 0'9 inch x 0ff3 
inches.
