I shall notice chiefly ostracions peculiar to the Red Sea, the Indian Ocean, and that part which washes the coast of tropical America. These fishes, like the tortoise, the armadillo, the sea-hedgehog, and the Crustacea, are protected by a breastplate which is neither chalky nor stony, but real bone. In some it takes the form of a solid triangle, in others of a solid quadrangle. Amongst the triangular I saw some an inch and a half in length, with wholesome flesh and a delicious flavour; they are brown at the tail, and yellow at the fins, and I recommend their introduction into fresh water, to which a certain number of sea-fish easily accustom themselves. I would also mention quadrangular ostracions, having on the back four large tubercles; some dotted over with white spots on the lower part of the body, and which may be tamed like birds; trigons provided with spikes formed by the lengthening of their bony shell, and which, from their strange gruntings, are called “seapigs”; also dromedaries with large humps in the shape of a cone, whose flesh is very tough and leathery. I now borrow from the daily notes of Master Conseil. “Certain fish of the genus petrodon peculiar to those seas, with red backs and white chests, which are distinguished by three rows of longitudinal filaments; and some electrical, seven inches long, decked in the liveliest colours. Then, as specimens of other kinds, some ovoides, resembling an egg of a dark brown colour, marked with white bands, and without tails; diodons, real sea-porcupines, furnished with spikes, and capable of swelling in such a way as to look like cushions bristling with darts; hippocampi, common to every ocean; some pegasi with lengthened snouts, which their pectoral fins, being much elongated and formed in the shape of wings, allow, if not to fly, at least to shoot into the air; pigeon spatulae, with tails covered with many rings of shell; macrognathi with long jaws, an excellent fish, nine inches long, and bright with most agreeable colours; pale-coloured calliomores, with rugged heads; and plenty of chaetodons, with long and tubular muzzles, which kill insects by shooting them, as from an air-gun, with a single drop of water. These we may call the flycatchers of the seas.
