The agouti and the armadillo are practically extinct and the only other mammals are ground squirrels, rats, a few other small rodents, and some bats.
This rodent, Coelogenys (or Agouti) paca, together with one or two other tropical American species, represents a genus near akin to the agoutis and included in the family Caviidae.
In the true pacas, Coelogenys (or Agouti), the first front toe is small, and both the first and fifth digits of the hind-foot are much inferior in size to the other three.
One is the hutia (agouti) or Cuban rat, of which three species are known (Capromys Fournieri, C. melanurus and C. Poey).
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.
