Common ringtail possums Pseudocheirus peregrinus, from here.

Belongs within: Diprotodontia.

The Pseudocheiridae are a group of possums including the ringtails and greater gliders. The group is most diverse in wet forests in northern Australia and New Guinea, though some species are found in a wider range of habitats, such as the common ringtail possum Pseudocheirus peregrinus.

Characters (from Long et al. 2002): Dental formula I1-3/1-2, C1/0, P1-3/1-3, M1-4/1-4; molars selenodont, with off-set postprotocrista and premetaconulecrista.
