Chiruromys resembles Pogonomys in external appearance. The pelage is soft and dense. The upper parts vary in color from grayish through fawn and brown to rich reddish brown, and the underparts are usually white.
Females have six mammae.
These rodents are found in forested areas from sea level to 2,000 meters. Unlike Pogonomys, they are completely arboreal, nest in hollow trees, and probably do all their foraging in the forest canopy. The diet and colonial habits are the same as in Pogonomys. A pregnant female and a newborn individual were found in December. The Johns Hopkins University Press.
