In most places about the neighbourhood of Fremantle, shells are found of the existing species along the coast, firmly impacted in its substance, particularly a large species of buccinum, as well as the strombus.
Accordingly, in the marls belonging to this period at Asti, Parma, Sienna, and parts of the Tuscan and Roman territories, we observe the genera Conus, Cypraea, Strombus, Pyrula, Mitra, Fasciolaria, Sigaretus, Delphinula, Ancillaria, Oliva, Terebellum, Terebra, Perna, Plicatula, and Corbis, some characteristic of tropical seas, others represented by species more numerous or of larger size than those now proper to the Mediterranean.

In the North-east Australian province, a different set of shells was dredged in similar depths, such as a Sigaretus, possibly new, Fissurella calyculata, Mitra obeliscus, a Turritella, a Murex, Columbella versicolor, and a new species off Cape York, Ranella pulchella, new, several Nassae, Phos senticosa and blainvillei, and sculptilis, in 3 and 5 fathoms, off Cape York; Strombus campbelli, in mud off Cape Upstart; Cerithium obeliscus, and a new species of the genus Obeliscus.
S.P. Woodward, are no longer inhabitants of the contiguous sea, as, for example, Strombus bubonius, which is still living on the West Coast of Africa, and Cerithium procerum, found at Mozambique; others are Mediterranean species, as Pecten Jacobaeus and P. polymorphus.
Victor, who was born on a Thursday, and therefore understood the birds' language, pricked up his ears and tried to catch what they were whistling. It was not long before he understood what they were saying. "I have the prettiest name," said one of them, "for I am called Strombus pespelicanus!" "I'm much the best looking," said the purple-snail, whose name was Murex and something else quaint.
The rapid movements of a small Strombus, which, when taken, beat about it with its shell, formed like a thin plate of horn, and armed with sharp teeth, were very curious. On breaking the stone which is formed by fragments of coral, a Sternaspis was found burrowing in the interior.
The well-known Strombus luhuanus lives on sand among the reefs at Eagle Island. A Cerithium inhabits mud-flats at Port Molle and Pipon's Islets. Of the holostomatous gasteropods inhabiting the Littoral zone, the Naticae, mostly well-known species, were taken in sandy localities on the north-east coast, and the Neritae in the same province, mostly on rocks or reefs.
Karl Meyer, in Hartung's "Madeira;" but in the collection made by myself, and in a still larger one formed by Mr. J. Yate Johnson, several remarkable forms not in Meyer's list occur, as, for example, Pholadomya, and a large Terebra. Mr. Mr. The huge Strombus of San Vicente and Porto Santo, S. Italicus, is an extinct shell of the Sub-apennine or Older Pliocene formations.
