{59}HABITS.--Of the habits of both this and of the preceding species little is known, for they have rarely, if ever, been seen alive by Europeans. According to the Rev. G. A. Shaw, the present species lives in the belt of forest-land stretching from the eastern forest into the heart of Betsileo, a few miles north of Fianarantsoa, where they are tolerably abundant, frequenting the tops of the highest trees. Among these it moves about on all fours (its very stout limbs having beautifully perfect hands), using its tail as a balance by twisting it round a branch. The tail is, however, not truly prehensile, the animal only employing it to steady itself, or to hold on slightly by. This species, whose food consists chiefly of fruit and insects, builds a nest in a fork amid the smallest branches near the top of some very high tree, the female bringing forth two and sometimes three young at a birth.

CHARACTERS.--Ears large and long; snout pointed; tail longer than the body, and equally haired; foot elongate. General colour reddish-grey. Unmistakably recognisable by the black dorsal streak bifurcating on the forehead into two branches, extending on the inner side of the ears and terminating over each eye. Facial portion of skull longer than cranial; angle of lower jaw much produced backwards and downwards; hind margin of palate extending back to hinder margin of posterior molar; hind perforations of palate large; border of maxillary swollen {60}in the canines and pre-molars. Upper anterior incisors much larger than the posterior, and both anterior to canines; anterior pre-molars canine-like, both vertically and proportionately longer than the median pre-molars of any other species of the family; median pre-molar compressed, with a fore and hind heel; the posterior pre-molar with a large internal talon. Molars comparatively small, but longer and narrower than in _M. coquereli_; anterior molar much larger than the posterior pre-molar, its hind inner cusp rudimentary; the posterior molar longer than the posterior pre-molar, and smaller than the other molars, its inner cusp wanting. Lower anterior pre-molar lance-shaped, vertically longer than the two posterior sub-equal grinders; molars sub-equal, much larger than the posterior pre-molar; posterior molar comparatively short, five-cusped. DISTRIBUTION.--Chiefly found on the west coast of Madagascar. V. COQUEREL'S DWARF-LEMUR. MICROCEBUS COQUERELI. _Cheirogalus coquereli_, Grandid., Rev. Mag. de Zool., xix., 1867, p. 85.
