Fig. 13, lateral view; fig. 14, superior view. The second phalanx is heavier than in M. jeffersonii. The median ridge of the proximal articular face is thick and widens inferiorly, forming a slight protuberance below the inner facet. The postero-dorsal ligamental ridges of the distal condyles are very pronounced. The osseous sheath on the inner side of the ungual phalanx has been broken away. The upper portion of the proximal articular face differs from M. jeffersonii in that the outer side is produced backward farther than the inner side. The tentative position of this digit is based upon Leidy's statement that in the first phalanges of the front foot "the proximal or metacarpal articulation is a deep, vertical concavity, extending from top to bottom of the bone, with an offset on each side inferiorly in the median phalanx, but on one side only in.
