and some in the flesh said to have been obtained from the lakes near 
Ballarat, in South Australia. It is one of the most common ducks 
north of the Burnet river. 
D. eytoni is abundant near Port Denison ; and from Rockingham 
Bay I have also obtained specimens. An egg taken from the ovi- 
duct by Mr. Rainbird, of Port Denison, measures 1°95 inch by 
1-5 in breadth ; it is of a light creamy white, and slightly ovate, and 
appears to be comparatively a very small egg for a bird of this size 
to lay.

Met with once in the swamps of the Herbert-river district. 
261. Larus paciricus. 
Larus pacificus, Gould, Handbk. B. Austr. ii. p- 385. 
I found this noble species rather plentiful on the mud-flats and 
margins of many of the rivers at low tides. They ascend the rivers 
in company with Xema jamesoni to a considerable distance. 1 
noticed several pairs near the wharfs at Rockhampton. 
262. XEMA JAMESONI.

I obtained these Terns on one occasion in Rockingham Bay ; 
they did not not appear to be rare in that neighbourhood.

I first found this beautiful species December 1865, at the mouth 
of the Richmond river, when I took it for S. nereis. I have 
repeatedly found them at different times during the last six years from 
as far south as Illawarra to Rockingham Bay in North-eastern 
Queensland, where it appears to be one of the most common species 
of Tern.
