The fur is dense, woolly, rather long, slightly wavy, and without luster.
Coloration is silvery gray to brown, being slightly lighter on the underparts.
The large ears have four transverse ridges and can be independently or simultaneously bent back and wrinkled downward from the tips well toward the base. This furling and unfurling of the ears is carried on frequently and produces a most quizzical expression. On the ends of all digits are flat disks of thickened skin that are helpful in grasping limbs and slippery surfaces. The long front digits and flattened hind digits have flattened nails, except the second digit of the hind foot, which is armed with a curved grooming claw. Females have two pairs of mammae.
