"A strange fish! Were I in England now (as once I was), and had but this fish painted, not a holiday fool but would give a piece of silver." Of curious and pretty shells there are so many varieties in these warm waters, that one must be well versed in conchology before daring to attempt an enumeration even of the commonest. I frankly admit "a little learning is a dangerous thing" in this interesting branch of natural science, and therefore cannot pledge myself to give details, while eager to set forth a few of the objects of interest, which present themselves to the open-minded though uninformed observer of sea-beaten rocks, mud flats, coral reefs, and the open sea. Well may the dabbler despair when nine titles are necessary to catalogue the oysters alone--oysters which vary from the size and independence--and the toughness (be it said) of the clam, to delicate morsels, so crowded and cemented in communities together, that they form bridges between severed rocks and shelves and cornices broad and massive; oysters flatter than plates, oysters tubular as service gas-pipes; the gold-lipped mother of pearl, the black-lipped mother of pearl, the cockscomb, the coral rock oyster, the small but sweet rock oyster, two varieties of the common rock oyster, besides the trap-door, the hammer, and another of somewhat similar shape whose official and courtesy title are both alike unknown, but which furnished knives and sharp-edged tools of various shapes to the original inhabitants of the island. The gold-lipped mother of pearl is rarely found, favourable conditions for it--deep water and strong currents--not being general. An occasional stray shell is picked up, and so far none has betrayed the presence of a valuable pearl. The black-lip occurs on the reefs, but not in any great quantity, and the most plentiful variety of the edible oyster is bulky in size and somewhat coarse in flavour.
