6. Delphinorhynchus pernettensis ? Delphinus pernettensis, Blainville. Delphinus delphis, var. Bonnaterre, Ency. Cetol. 21. Dauphin, Pernetty, Voyage aux Isles Malouines, 99. t. 2. f. 1. A head, apparently belonging to this species, was brought home and deposited in the collection of the British Museum. This animal is very common upon the northern coasts of New Holland. 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. Upon the North-east Coast, within the reefs, the sea is crowded with Balaena physalis, Linn., or fin-backed whales, as they are called by the whalers, who pay little attention to them, on account of the danger of approaching them. His boats were sometimes placed in critical situations from these animals suddenly rising to the surface of the water close to them, and lashing the sea with their tremendous fins, and their occasionally leaping out of the water, and falling down with a crushing weight. Their colour is generally of a cinereous hue, but a few were noticed that were variegated black and white. The whales of the North-west Coast appeared to be of the same species, but of a darker colour. At one of the anchorages, near Cape Leveque (volume 2 page 91) the brig was for a whole night surrounded by these enormous fish, and the crew in momentary dread of their falling on board, the consequence of which would have been very disastrous. The noise of their fall in the water, on a calm night, was as loud as the report of a cannon. ... AVES.
