Chiruromys

Chiruromys is a genus of Old World mouse that is restricted to New Guinea and the nearby islands of Goodenough, Fergusson, and Normanby.

Characteristics
These are small arboreal rats with long tails. Head and body is 8.4 - 17.5 cm, tail is 12.8 - 24.5 cm, and weight is 23 - 122 g. The fur is grey to brown above with a white belly. They are restricted to forests where they spend all of their time in the canopy. They live in groups usually consisting of a breeding pair and their offspring (usually one to three) (Nowak, 1999).

Classification
Musser and Carleton (2005) considered Chiruromys to be a member of the Pogonomys Division within the Murinae along with the genera Pogonomys, Hyomys, Macruromys, Mallomys, Coccymys, and Anisomys. It is considered a New Guinea Old Endemic, part of the initial wave of murines colonizing the island.
