What, then, is this cetaceous monster of which no Cuvier ever thought?

It has not the fetid smell of whale-oil, or that of the other cetaceous animals which spout water.

Captain King, in his manuscript, remarks, that the coasts of New South Wales, and the north-western side of New Holland, abound in cetaceous animals.

Are these cetacea peculiar to the great rivers of South America, like the manatee, which, according to Cuvier, is also a fresh water cetaceous animal?
