 Rh Dictionaries are silent respecting 'kropgans,' or render it by 'pelican.' I am inclined to think that this rendering arises from a confusion between 'kropgans' and the German word 'kropfgans,' and that 'kropgans' was formerly applied to domestic geese in general which were being fed for the market, and also, as in the present instance, to the wild goose from which they were derived, namely to the Grey Lag Goose (Anser ferus). If this be so, the Australian bird with which the kropgans is compared in the Journaal may be the Cape Barren Goose (Cereopsis novæ-hollandiæ) which is found sparingly in Western Australia. The 'Rotgans' is the Brent Goose (Branta bernicla) and the Australian bird which most resembles it is the Musk Duck (Biziura lobata), which also is found in the west of Australia, although more sparingly there than in the south of the island continent.

Other birds which were seen at the same part of the Australian coast were 'Duikers,' by which name Cormorants are probably designated, Cockatoos and Parrakeets. It is said that all the birds were shy and flew away at the approach of human beings. No aborigines were seen, although smoke was visible.

On the 15th of January De Vlaming quitted the anchorage near Rottnest Island, and followed the coast until 30° 17' S. lat. was reached. Two boats were there sent to the shore and soundings were taken. The country near the landing-place was sandy and treeless, and neither human beings nor fresh water were to be seen. But footmarks resembling those of a dog were seen, and also a bird which the Journaal calls a 'Kasuaris' and which must have been one of the Emus.

On the 30th of January, 26° 8' S. lat. was observed, which is
