Note on the occurrence of some Australian Arcleidae in Tasmania

The past summer and autumn have been marked by a special visitation of two species of Australian Herons to Tasmania.
One, the White Egret, Herodias alba, Linn., which has hitherto been an occasional straggler to the island, has occurred in considerable numbers during the summer, both in the north and south. The other, Ardea pacifica, Latham, a rare visitant to Tasmania, has been half a dozen times met with in the north during the past two months.
The localities visited by the White Egret appear to have been the basin of the Derwent, including the Sorell district, the Midlands, and the vicinity of the Tamar and Esk rivers in the north
