The borings of marine shellfish visible in these columns between II and 19 ft.
L * An independent anatomical investigation of the Mollusca had been carried on by the remarkable Neapolitan naturalist Poli (1791), whose researches 2 were not published until after his death (1817), and were followed by the beautiful works of another Neapolitan zoologist, the illustrious Delle Chiaje.3 The embranchement or sub-kingdom Mollusca, as defined by Cuvier, included the following classes of shellfish: (1) the cuttles or poulps, under the name Cephalopoda; (2) the snails, whelks and slugs, both terrestrial and marine, under the name Gastropoda; (3) the sea-butterflies or winged-snails, under the name Pteropoda; (4) the clams, mussels and oysters, under the name Acephala; (5) the lamp-shells, under the name Brachiopoda; (6) the seasquirts or ascidians, under the name Nuda; and (7) the barnacles and sea-acorns, under the name Cirrhopoda.
This was properly the name of the shellfish (Purpura, Murex) which yielded the famous Tyrian dye, the particular mark of the dress of emperors, kings, chief magistrates and other dignitaries, whence "the purple" still signifies the rank of emperors or kings.
The western and larger species gathers its food, consisting chiefly of sea-weeds and shellfish, on rocks at low water; but it is also known to eat birds' eggs.
The kima, a great mussel weighing (without shell) 20 to 30 Ib, and other shellfish, are eaten, as are also dogs, flying foxes, lizards, beetles and all kinds of insects.
Perna, a ham-shaped shellfish, but this is due to Florio, who by a mistake glosses parnocchie, prawne-fishes or shrimps.
Perna and pernocchia meant a shellfish which yielded "nacre" or mother-of-pearl.
Not that all architectural ornament is to be neglected even in the rudest periods; but let our houses first be lined with beauty, where they come in contact with our lives, like the tenement of the shellfish, and not overlaid with it.
