All the table cases of this gallery, with the exception of a few small side tables, are covered with the vast varieties of the of molluscous or soft animals. These shells, scattered over no less than forty-nine tables, represent the architectural capacities of the great order of soft-bodied animals, only inferior in rank, in Cuvier's "Animal Kingdom," to the Vertebrate animals.
A marine molluscous fauna, however, agreeing in character with that of Moel Tryfaen, and comprising as many species, has been found in drift at Macclesfield and other places in central England, sometimes reaching an elevation of 1200 feet.
I should lead the audience on to listen to comparisons with other members of the great family which once associated with Adam. I should lay the foundation for an instructive course of natural history, and from vertebrated mammifers who knows but we might gradually arrive at the nervous system of the molluscous division, and produce a sensation by the production of a limpet?"
At the very bottom of the Silurian series, in beds which are by some authorities referred to the Cambrian formation, where the signs of life begin to fail us even there, among the few and scanty animal remains which are discoverable, we find species of molluscous animals which are so closely allied to existing forms that, at one time, they were grouped under the same generic name.
It is scarcely less evident, from the geological record, that the progress of organic life has observed some correspondence with the progress of physical conditions on the surface. We do not know for certain that the sea, at the time when it supported radiated, molluscous, and articulated families, was incapable of supporting fishes; but causes for such a limitation are far from inconceivable.
In the most eastern room of this gallery are a few tables upon which are deposited the shells and tubes of molluscous animals, to illustrate their changes, and the way in which the animal adapts them to his position. The third and fourth tables will, perhaps, interest the general visitor.

Kotzebue's First Voyage, vol. iii. p. 222. The large claws or pincers of some of these crabs are most beautifully adapted, when drawn back, to form an operculum to the shell, nearly as perfect as the proper one originally belonging to the molluscous animal. I was assured, and as far as my observations went I found it so, that certain species of the hermit-crab always use certain species of shells.
If you travel intelligently, you discover the relativity of all customs and ideas, you distrust your own beliefs, your backbone is relaxed, your vitality snapped, and you come home a molluscous cosmopolitan.
The truth is, that it is the name given to a beautiful molluscous animal, which by means of a sort of sail, the wind blows along as if it were a real boat. It consists of a bladder, tinted with various hues, and this keeps it afloat; while long tentaculae, of a deep purple colour, extend beneath, some of them several feet in length, with which it captures its prey.
