SIMIA, the MONKEY, in zoology, a genus of quadrupeds belonging to the order of primates. They have four fore-teeth in each jaw, placed near each other; the dog-teeth are solitary, and remote; and the grinders are obtuse. There are 33 species: Of these, three, viz. the satyrus, sylvanus, and inuus, have no tail. Other three of them, viz. the nemestrina apedia, and sphinx, have short tails. The other 27 have long tails. The specific distinctions are taken from the colour, and other circumstances.—The monkey-kind are remarkable for activity, a low species of cunning, and a facility of imitating the actions of men and other animals. The sagacity and docility of the simia are so well known, that it is needless to spend time in giving instances of either.
