Mathews ; it is distinct from the eastern bird. It is distributed all 
along the coasts of Mid- and Western Australia and the Northern 
Territory. 
Observed throughout June, July, and August; being seen 
generally on the tidal flats at low water, but flying about in 
flocks when the tide is high along the outer shores. Specimens 
were shot on June 10th and July 4th.

This species was observed commonly, and both white and grey 
forms were seen, though only the latter , which is by far the most 
plentiful, was obeuned: They were generally to be found about 
the rocks and cliffs of the outer aioe seldom frequenting the 
more sheltered inlets. A nest, containing three eggs, was dis- 
covered on a small flat islet to the north of Hermite. It formed a 
lining of loose sticks to a depression in the rock, a few feet above 
high-tide level. Only a yard or two away there was an Osprey’s 
nest with newly-hatched chicks; although this bird will not 
tolerate another nest of its own species upon the same island, it 
does not in the least resent the presence of that of a different 
bird.

Observed in small parties, usually of a dozen or so, around the 
islands to the north of the group. ‘They do not breed in the 
vicinity.

This species, which enjoys a wide distribution, from the coasts 
of India, Ceylon, Malay Archipelago, and Australia to Western 
Polynesia and Tonga, occurs abundantly on the islands off North- 
Western Australia. Two pairs were nesting upon the Monte Bello 
Group, one at the extreme south-eastern end of Trimouille, and 
another on a small flat islet tothe north of Hermite. The former 
nest was placed upon a sloping ledge of a cliff, and a great 
quantity of material was employed to bring the outer edge to the 
level of the inner portion ; it was consequently a bulky structure, 
5 ft. 6 in. in diameter—composed of sticks and seaweed, with no 
obvious cavity or lining—forming a safe and level platform for 
the single chick. In the second instance, there was practically
