The capybara (Hydrochoerus capybara) is also numerous in this region.
Of the amphibious rodents, the pi-ea (Cavia aperea), mod, (C. rupestris), paca (Coelogenys paca), cutia (Dasyprocta aguti) and capybara (Hydrochoerus capybara) are noteworthy for their size and extensive range.
There are six species of monkey corresponding to those of Guiana and the Amazon valley, the sloth and ant-eater, 12 known genera of rodents, including many species of Mures, the cavy, the capybara, the paca, the nutria, the agouti, the tree porcupine, Loncheres cristata, Echimys cayen and the Brazilian hare.
The capybara, again, is most probably the native host of T.
The jaguar is usually found singly (sometimes in pairs), and preys upon such quadrupeds as the horse, tapir, capybara, dogs or cattle.
CAPYBARA, or Carpincho (Hydrochaerus capybara), the largest living rodent mammal, characterized by its moderately long limbs, partially-webbed toes, of which there are four in front and three behind, hoof-like nails, sparse hair, short ears, cleft upper lip and the absence of a tail.
Extinct species of capybara occur in the tertiary deposits of Argentina, some of which were considerably larger than the living form.
In the squirrels and porcupines the tibia and fibula are distinct, but in rats and hares they are united, often high up. The hind foot is more variable than the front one, the digits varying in number from five, as in squirrels and rats, to four, as in hares, or even three, as in the capybara, viscacha and agouti.

Hydrochaerus, in which all the feet are fully webbed, includes a single species, the capybara, or carpincho, the largest of living rodents.
The rodents are numerous and include most, if not all, of the Amazonian species - the capybara (Hydrochoerus capybara), cavia (C. aperea), paca (Coelogenys paca) and cutia (Dasyprocta aguti), all amphibious and having an extensive range.
There are deer in the forests and on the open savannahs, the rabbit and squirrel are to be seen on the eastern slopes of the Andes, and partly amphibious rodents, the "capybara" (Hydrochoerus) and "guagua" (Coelogenys subniger), are very numerous along the wooded watercourses.
