The land crab is a member of the family 'Gecarcinidae', and is remarkable for the curious modification of the carapace in the region of the gills, which enables it to lead a terrestrial existence. The land crabs occurs in the warmer regions of both hemispheres, but the best known one is the black 'Gecarcinus ruricola' of Jamaica and the West Indian islands generally. It inhabits burrows on the hills a short distance from the coast, wanders about at night or during rains, in search of vegetable food, and makes an annual migration to the shore to spawn, often passing through houses instead of going around them. They are sometimes eaten. Many other crabs are largely terrestrial, as the oriental cocoa-nut crabs; and a species of Ocypoda very troublesom in Ceylon, by burrowing in lawns, garden paths, and the like.

"In the thirteenth year of the reign of Nabuchodonosor, the two and twentieth day of the first month, the word was given out in the house of Nabuchodonosor king of the Assyrians, that he would revenge himself. And he called all the ancients, and all the governors, and his officers of war, and communicated to them the secret of his counsel: And he said that his thoughts were to bring all the earth under his empire. And when this saying pleased them all, Nabuchodonosor, the king, called Holofernes the general of his armies, And said to him: Go out against all the kingdoms of the west, and against them especially that despised my commandment. Thy eye shall not spare any kingdom, and all the strong cities thou shalt bring under my yoke. Then Holofernes called the captains and officers of the power of the Assyrians: and he mustered men for the expedition, as the king commanded him, a hundred and twenty thousand fighting men on foot, and twelve thousand archers, horsemen."

The pug is a breed of small, short-haired lap dogs, probably of Oriental origin, and introduced into Europe by way of Holland in the sixteenth century. The breed is characterized by the shortness of the face and uplifted form of nose. Only a fawn color, with blackish face, was known until about 1875, when a wholly black variety was introduced into the West from China. The pug is essentially a house dog, good-tempered and affectionate. Unless restrained, it becomes extremely fat. Its weight should not exceed fifteen pounds; its form should be compact and elegant, though robust, with straight legs, the face much wrinkled and forehead high, the coat smooth and silky, and the tail always tightly curled over the hip. The face and thin, small ears should be black, and in the fawn-colored breed a blackish line should run along the spine.
