in the tarsus the cuboid with the calcaneum only articulates proximally The component bones of both the carpus and tarsus mutually interlock only to a very slight extent ; and the whole structure of these parts is the simplest The present Suborder is charac- type obtaining in the Ungulata, terized by a bunodont or (in the higher forms) a lophodont type of cheek-dentition, the characters of which foreshadow those of both the Artiodactyla and Perissodactyla there are usually five digits to both : the pes and manus, the terminal phalangeals being acuminate ; the humerus has an ectepicond3lar foramen, the astragalus a uniformly convex distal articular surface, the femur a third trochanter, and there are no fibular facettes on either the astragalus or the calcaneum The skeleton of the type genus of the family Phenacodontidce in the accompanying woodcut is figured 23) ; and apparently indicates a primitive form allied to Hyracotherium PERIPTYCHIDtE Family The dentition is (fig bunodont the digits five on each foot and the premolars are simple ; ; ; the astragalus has no trochlea Genus PERIPTYCHUS, Syn, Catathl
