Description (after Garman, 1913): Teeth in young quincuspid, becoming tricuspid with acquisition of the molars; molars elongate with a longitudinal keel. This keel, in the specimen described, lies more to the outer side of the tooth than on such species as C. quoyi and C. francisci; it is as if the tooth were turning outward to present more of its inner side as a grinding surface. On older specimens the cusps and keels are worn away, the molars are more swollen and the symphyses are proportionately longer, but not so much so as on C. philippi. As the molars increase in width the symphyses become longer.
