Of the molars, two are developed before the change of the pre-molars.
In the lower jaw the incisors change first, and when two or three pre-molars have developed the last molar has still to come.
Of the pre-molars, the anterior one is canine-like, and is equally distant from the canine and its own next neighbour.
A specimen in the British Museum has four pre-molars in each upper jaw, instead of the normal three of the Cebid.
There are three pre-molars on each side, below and above, much worn: once there was a fourth, but it was shed early.
The two small bicuspid "pre-molars" and the three large molars follow these on each side in each jaw.
