Amongst these specimens I will quote from memory only the elegant royal hammer-fish of the Indian Ocean, whose regular white spots stood out brightly on a red and brown ground, an imperial spondyle, bright-coloured, bristling with spines, a rare specimen in the European museums—(I estimated its value at not less than £1000); a common hammer-fish of the seas of New Holland, which is only procured with difficulty; exotic buccardia of Senegal; fragile white bivalve shells, which a breath might shatter like a soap-bubble; several varieties of the aspirgillum of Java, a kind of calcareous tube, edged with leafy folds, and much debated by amateurs; a whole series of trochi, some a greenish-yellow, found in the American seas, others a reddish-brown, natives of Australian waters; others from the Gulf of Mexico, remarkable for their imbricated shell; stellari found in the Southern Seas; and last, the rarest of all, the magnificent spur of New Zealand; and every description of delicate and fragile shells to which science has given appropriate names. Apart, in separate compartments, were spread out chaplets of pearls of the greatest beauty, which reflected the electric light in little sparks of fire; pink pearls, torn from the pinna-marina of the Red Sea; green pearls of the haliotyde iris; yellow, blue and black pearls, the curious productions of the divers molluscs of every ocean, and certain mussels of the water-courses of the North; lastly, several specimens of inestimable value which had been gathered from the rarest pintadines.
