What is "peramelidae"

The Peramelidae family of marsupials contains all of the extant bandicoots. One known extinct species of bandicoot, the pig-footed bandicoot, was so different from the other species, it was recently moved into its own family. Four fossil peramelids are described. They are found throughout Australia and New Guinea, with at least some species living in every available habitat, from rainforest to desert.
