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.

Lepilemur pallidicauda, Gray, P. Z. S., 1872, p. 850.
Lepilemur mustelinus (nec. Is. Geoffr.), Schl., Mus. P. B., vii., p. 317 (in part).
Characters.—Smaller than the last species; head much broader than it is long; snout short and conical; ears ovate, exposed, short-haired; tail long, thicker at the end, and covered with softer and longer hairs. Fur pale or reddish-grey; head dark brown; the shoulders and outer side of the arms grey, washed with brown; chin, breast, and inner side of limbs and under side of body whitish; upper side of the base of the tail rather dark brown, this colour extending further down in the tail of the female; rest of the tail uniform pale brownish or greyish-red.
Skull very broad compared with its length, more massive, and showing a shorter muzzle than in L. mustelinus; orbits smaller than in any of the other species in Group A.
Distribution.—South-western Madagascar.
