CHARACTERS.--Fur soft and woolly; ears rounded, naked excepting at the base behind; muzzle elongated. Above, reddish-grey. Face and cheeks grey; throat white; under side of body and inner side of limbs, pale grey; tail short-haired, the posterior third dark brown. Length of body, 14 inches; and tail 10 inches.

Skull large and massive; the brain-case small and inflated; facial region long, differing in this character from _L. ruficaudatus_; orbits very large, thus differing from the three remaining species of the larger group (A); the process of the maxilla intervening between the nasal and lachrymal bones; molar teeth large.

DISTRIBUTION.--This species occurs in the north-east of Madagascar, and, according to Grandidier, in the north-western corner of the island.

HABITS.--The "Fitili-ki," as the natives have named this animal, is found in the forests in small companies. It is nocturnal in its habits, feeding on leaves and fruits.
