An excitable conchologist would surely have fainted dead away before other, more numerous glass cases in which were classified specimens from the mollusk branch. There I saw a collection of incalculable value that I haven’t time to describe completely. Among these exhibits I’ll mention, just for the record: an elegant royal hammer shell from the Indian Ocean, whose evenly spaced white spots stood out sharply against a base of red and brown; an imperial spiny oyster, brightly colored, bristling with thorns, a specimen rare to European museums, whose value I estimated at 20,000 francs; a common hammer shell from the seas near Queensland, very hard to come by; exotic cockles from Senegal, fragile white bivalve shells that a single breath could pop like a soap bubble; several varieties of watering-pot shell from Java, a sort of limestone tube fringed with leafy folds and much fought over by collectors; a whole series of top-shell snails—greenish yellow ones fished up from American seas, others colored reddish brown that patronize the waters off Queensland, the former coming from the Gulf of Mexico and notable for their overlapping shells, the latter some sun-carrier shells found in the southernmost seas, finally and rarest of all, the magnificent spurred-star shell from New Zealand; then some wonderful peppery-furrow shells; several valuable species of cythera clams and venus clams; the trellis wentletrap snail from Tranquebar on India’s eastern shore; a marbled turban snail gleaming with mother-of-pearl; green parrot shells from the seas of China; the virtually unknown cone snail from the genus Coenodullus; every variety of cowry used as money in India and Africa; a “glory-of-the-seas,” the most valuable shell in the East Indies; finally, common periwinkles, delphinula snails, turret snails, violet snails, European cowries, volute snails, olive shells, miter shells, helmet shells, murex snails, whelks, harp shells, spiky periwinkles, triton snails, horn shells, spindle shells, conch shells, spider conchs, limpets, glass snails, sea butterflies—every kind of delicate, fragile seashell that science has baptized with its most delightful names. Aside and in special compartments, strings of supremely beautiful pearls were spread out, the electric light flecking them with little fiery sparks: pink pearls pulled from saltwater fan shells in the Red Sea; green pearls from the rainbow abalone; yellow, blue, and black pearls, the unusual handiwork of various mollusks from every ocean and of certain mussels from rivers up north; in short, several specimens of incalculable worth that had been oozed by the rarest of shellfish. Some of these pearls were bigger than a pigeon egg; they more than equaled the one that the explorer Tavernier sold the Shah of Persia for 3,000,000 francs, and they surpassed that other pearl owned by the Imam of Muscat, which I had believed to be unrivaled in the entire world.
