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. “In the eighty-ninth genus of fishes, classed by Lacepede, belonging to the second lower class of bony, characterised by opercules and bronchial membranes, I remarked the scorpaena, the head of which is furnished with spikes, and which has but one dorsal fin; these creatures are covered, or not, with little shells, according to the sub-class to which they belong. The second sub-class gives us specimens of didactyles fourteen or fifteen inches in length, with yellow rays, and heads of a most fantastic appearance.
