Cercopithecidae

The Cercopithecidae, or Old World Monkeys as they are commonly called in the Traveler's Tongue, are group of primates native to Rathnir. Their most commonly known members include baboons and macaques. They are more closely related to apes (including humans) than they are to New World Monkeys.

It is thought by some scholars that elves belong to the cercopithecid family, as they may have evolved from macaques.
