are deposited, are numbered from 13 to 24. The four first cases (13-16) are covered with Crabs of various kinds, including the long-legged spider-crabs, common crabs with oysters growing upon their backs, and fin-footed swimming crabs. The next case (17) contains in addition to the long-eyed or telescope crab, varieties of the land-crab, which is found in various parts of India; one kind, that swarms in the Deccan, commits great ravages in the rice-fields. The two next tables are covered with Chinese crabs, square-bodied crabs; those crabs with fine shells known as porcelain crabs, and the curious death's head crab, which seems to build a kind of nest of sponge or shells. But upon the next table (20) the visitor will find the most remarkable of the crabs, together with an astonishing lobster. This crab is known as the hermit crab. The visitor will perceive, that it has a long naked tail; and he should know that the one all-absorbing care of its life seems to be to find a place of safety in which this unprotected part may be screened from the dire mischances of war. Accordingly, at an early age, it sets out in search of a deserted shell into which it backs its tail; or if an unoccupied shell be not at hand, without much ceremony, the hermit contrives a summary ejectment of the lawful tenant, that it may shield its tail and be at rest. Upon the same table with this unceremonious hermit, lies the tree-lobster, which is believed to climb cocoa-trees in search of the nuts. Upon the next table (21) are the sea craw-fish and sea locusts; and upon the succeeding table (22) the visitor will remark the destructive scorpion-lobster of India, the excavations of which seriously damage the roads of that part of the world; Shrimps in all their varieties; the delicate alima, with its pale thin shell; and the long king crab. Upon the last two tables devoted to shell fish, or crustacea, are spread the goose shells or barnacles, whale lice, and I the sea acorn. Having examined these crustacea, the visitor should turn his attention to the twelve tables (1-12) upon which a fine collection of INSECTS is spread. The first eight tables are covered with varieties of THE BEETLE TRIBE.
