M. de la Borde has also transmitted several particulars; he says, "There are two species of ant-eaters which inhabit the woods of Guiana, the one larger than the other; they run very slow, and when they swim across large rivers which is a common practice, it is easy to knock them on the head with a stick; but in the woods it is necessary to use muskets, for the dogs refuse to hunt them. The great ant-eater tears up the nests of wood-lice, which he easily discovers; he is a dangerous animal to encounter, as he gives most severe wounds with his claws, with which he successfully defends himself against the most fierce animal of this continent, such as the jaguars, cougars, &c. and with which he also kills many dogs, who are therefore afraid of him. He is said to feed on ants, for which his tongue appeared well calculated, but I found in the stomach of one a great number of wood-lice, which had just been swallowed. The females bring forth in the holes of trees, and have one at a time, and at those periods they will even attack men. The savages at Cayenne eat the flesh, although it is black and unsavory; their skins are thick and hard; they do not attain their full size before they are four years old; and the whole of their respiration is performed through their nostrils. The smaller one has whitish hair, about two inches long; it has no teeth, but its claws are very long; this, as well as the former feeds during the night; the female also has but one at a time, and they perfectly resemble each other, but the latter is more scarce to be met with than the former." This gentleman sent me also the following remarks upon our third species. "It has bright hair, rather of a golden colour; it feeds upon ants, which adhere to its tongue; it is not bigger than a squirrel, runs very slow, and is easily taken; it fixes itself so fast to a stick or branch that it may be carried in that manner to any distance, and they are frequently found thus fixed; these, like the former bring forth but one at a time, in the holes of trees, and feed also in the night; they are not by any means scarce, though it is difficult to distinguish them on the trees." THE LONG AND THE SHORT-TAILED MANIS. These animals are commonly known under the name of scaly lizards; we reject this denomination; 1st, because it is a compound; 2dly, because it is ambiguous, and applied to both species; 3dly, because it is wrongly imagined; these animals being not only of another species, but even of a different class, than the lizards, which are oviparous reptiles, while the pangolin, and the phatagen, as they are called in their native countries of the east, are viviparous quadrupeds.
