collecting tour in the vicinity of Rockingham Bay, for Dr. 
Ramsay in 1867 is the only specimen that I have seen in any 
collection. I give Dr. Ramsay’s description of it which appeared

of this specimen is of a dirty greenish-white, the ground colour 
almost obscured by dots, spots, and a few blotches of brownish-red 
and yellowish-brown, many of the larger markings appearing as 
if beneath the surface ; length 1'08 x 086 inch.”

Handbook to the Birds of Australia, Yol. ii., p. 344 : — “ As the 
nest and eggs of this species have not yet been discovered, they 
form some of the desiderata to which I would call the attention 
of the rising ornithologists of Australia ; and I can assure them 
that the study of the eggs will greatly assist them in assigning the 
birds to which they belong to their proper genus.”

different generic term for this bird, as the egg materially differs 
from those of the typical Porzanw.
