The Guinea Pig is one of the family of cavies. This beautiful little animal is too well-known to require description. It may be remarked, however, that the name Guinea Pig is altogether a mistake, since the creature is found wild only in South America, and is not a native of Guinea in Africa. Very likely it was originally brought from Guiana, and this has led to the misnomer. There are several species of Guinea pig in South America, differing from one another in size, shape, and colour. Besides the large Capivara and the little Guinea Pig, there are several intermediate kinds. These are known as the True Cavies, and are usually called Agoutis, or Acouchis. The agoutis are about the size of the common hare, and run almost as swiftly. For their food they prefer nuts to herbage, which is natural enough in a region where the latter is scanty and the former exists in plenty; and in eating they “squat” upright on their haunches, and convey the food to their mouth after the manner of squirrels. The agouti, like the hare, frequently rolls over when descending a hill at full speed—a habit, or rather an accident, due to the same cause in both animals, namely, the great length of the hind legs. When angry, the agouti stamps with the fore-feet, grunts like a young pig, and erects the bristly hair upon its crupper after the manner of porcupines.
There are many species of agouti throughout tropical America and the West India Islands, and the range of the genus extends as far south as the plains of Patagonia.
The Pacas form another genus belonging to the family of the cavies that may be also grouped with the hares and rabbits. They burrow like the common rabbit, and their food consists of nuts, fruits, and roots. Their flesh is excellent; and on this account they are hunted eagerly, both by the Indians and whites who dwell in the countries where they are found. There are several species of them in South America, and they were also very common at one time in the West India Islands; but on account of the persecution of many enemies—more especially of hunters—they are now comparatively rare.
With the hares and rabbits may be classed still another family of South American animals, and one of the most interesting of the whole group. These are the Chinchillas and Viscachas. The place assigned to them by some naturalists is with the hamsters, and therefore they are grouped with the rats; but an examination into the habits of these animals shows that they are in reality representatives of the hares and rabbits on the elevated table-lands of Chili and Peru, as also over the whole plain country of La Plata and Patagonia. There are several species known indifferently as Viscachas and Chinchillas; but the true Chinchilla, celebrated for its soft and beautiful woolly coat, is an inhabitant of the elevated plateaux of the Andes, where the climate is as cold as in Siberia itself. The natural history of these rodents is full of curious interest, and deserves to be given more in detail, if our space would only admit of it.

Elephants.
The Elephant is by far the largest of land animals, and for this reason one of the most interesting to the student of zoology; but even without this superiority, he possesses qualities that entitle him to rank among the curious objects of creation.
In ages long gone by there were elephants upon the earth—or animals resembling elephants—as much larger than the existing species as these are superior in size to other quadrupeds. Such were the mammoths and mastodons, the skeletons of which are occasionally found buried beneath the surface of the soil in different parts of the world.
