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
