In other species the summits of the ridges are divided into conical cusps, and may have accessory cusps clustering around them (as in M.
When the summits of these are worn by mastication their surfaces present circles of dentine surrounded by a border of enamel, and as attrition proceeds different patterns are produced by the union of the bases of the cusps, a trefoil form being characteristic of some species.
Presence of from four to five sharp cusps or tubercles on the crown of the molars.
Molars in general characters resembling those of Sarcophilus, but of more simple form, the cusps being less distinct and not so sharply pointed.
In the lower jaw the molars more compressed, with longer cusps; the last not notably smaller than the others.
