From tapiroid types the development of thetympanic region distinguishes it. From Proboscidians the slender feetand reduced ulna, as well as the longitudinal crests of the teeth separateit. It then remains to compare it with Pertssodactyles of the types whichpossess strong canine teeth. In points of resemblance to these we havethe flat claws and separate scaphoid and lunar bones; nevertheless thegreater number indicate truer affinity to the Carnivora. Such are theexternal transverse glenoid cavity, the teeth with longitudinal crests,the slender digits, the well-developed tympanic bone; confirmatory arethe large canine teeth, the incomplete orbit, and the projecting innercondyle of the humerus. The form of the claws is not absolutely in-compatible with the same order, as it is approximated by some of theSeals, i M>>;6i^ iiif %.§t;Etitiiams. ^^0i lI^^ J
