Not illustrated. 1891 Excerpt: ... Leptomeryx. The shaft is flattened and nearly straight. The distal end is much less expanded than in T ragulus. The ulna is much reduced and has a very slender shaft; the olecranon is higher than in the modern genus, but of less antero-posterior diameter. The manus, which has been described by Cope (No. IO), is very traguline in character, both in general appearance and in details of structure. The scaphoid is not preserved in any of the specimens, nor is the trapezium; not improbably the latter was altogether wanting. The proximal end of the lunar is shaped very much as in the Pecora, but the distal end is very different, in that the lunar rests almost wholly upon the unciform and has only a lateral contact with the magnum--a traguline character upon which Cope has laid much stress. The cuneiform is very small, and is not in contact with the radius; its ulnar surface is saddle-shaped and extends well down upon the external surface of the bone. The trapezoid and magnum have coalesced; the compound bone is low, rising slightly behind; it is supported almost exclusively by the scaphoid. Distally it presents facets for the second and third metacarpals. The unciform is the largest bone in the carpus, but is not so high proportionately as in Tragulus. The metacarpus consists of four digits, none of which shows any tendency to coalesce with another. The lateral digits are very slender, though not so much so as in the chevrotains; the median digits are of about the same relative length, but decidedly more slender. Metacarpal II. articulates with a downward projection from the trapezoid element of the trapezo-magnum. Metacarpal III. articulates medially with the side of this same projection, proximally with the magnum, and laterally with the unciform, sending out ...
