The fauna partakes partly of the character of that of the equatorial regions of South America, and of the semi-tropical districts of Mexico. There are several varieties of ant-eaters, similar to those found in the valley of the Amazon, while the grey squirrel of more northern latitudes skips playfully amid the forests of the interior. In the woods and wide savannahs are two or more varieties of deer--one resembling the European deer in colour, but of less size, and adorned with large antlers. The other is of a lighter and browner tint, possessing short, smooth-pointed horns. The peccary is common in the valleys and low ground along the coast; while the waree, or wild hog, runs in large droves in many districts. The tapir, similar to that of the southern continent, also frequents the seashore and banks of the rivers; and another species, peculiar to the region, is said to have been discovered lately. There are numerous varieties of monkeys, among which are the brown, the horned, and the little, playful capuchin. The raccoon, as elsewhere, is common, and is noted for its thieving propensities. It lives chiefly on animal food. There is an interesting little opossum of about ten feet in length, of a grey colour, with a somewhat large head, and a long and very flexible tail--the feet being provided with sharp claws. When the young leave the mother's pouch, she can place them on her back, to which they cling, while she scrambles amid the forest boughs. Besides the great ant-eater, there is the smaller striped ant-eater, and the little ant-eater. There is a curious creature, called the quash, resembling the ichneumon, which possesses a peculiarly fetid smell, and is known for its powerful, lacerating teeth. There are several species, also, of the armadillo, distinguished as the three-banded, eight-banded, and nine-banded. The paca is also very plentiful, and becomes easily domesticated. It reaches two feet in length, and its thick, clumsy form, of a dusky brown colour, may be seen scampering through the woods. The agouti, or Indian cony, or rabbit, frequents the same region as the paca, and is about the size of an ordinary hare. It does not, however, run in the same way, but moves by frequent leaps. The jaguar ranges through the whole of this part of the continent, and is remarkable for its large size and great strength. Not only does it frequently kill full-grown cattle, and drag them to its lair far-away in the woods, but, if irritated, it does not hesitate to attack human beings. The tiger-cat, or ocelot, which much resembles a common cat, but is considerably larger, is also found in the forest; but at the sight of man it takes to flight, and is, therefore, less frequently seen than its fiercer relatives. The puma also makes its way from one end of the country to the other; but though destructive to cattle, it is said here, as elsewhere, to fly from the face of man. The savage wolf, the cayote, is frequently met with.
