    arises, close to the common tendon, from the internal condyle of the humerus, but somewhat deeper. It lies beneath flexor com- munis digitorum, and to its radial side. At the lower fourth of the fore-arm it ends in a round tendon, which joins the deep surface of the common flexor. Another muscle arises by fleshy fibres from the ulna, beneath the ulnar origin of flexor carpi ulnaris, and to its inner side. It consists of a small conical bundle of muscular fibres, ending in a thin round tendon near the upper extremity of the fore-arm. The tendon joins the deep surface of the tendon of the common flexor on its ulnar side. C. and L.—283, fig. 2 (jl, /a1) ; 284, fig. 2 (/a1, /a, the letters of the preceding figure are reversed here, /a2), fig. 4 (/a). Flexor b'evis digitorum arises from the annular ligament of the wrist, where it forms a sheath for flexor carpi radialis. It con- sists mainly of fleshy fibres. Opposite the base of the radial sesamoid it divides into two nearly equal masses, of which that to the radial side is inserted into the sheath of the long flexor tendon of the 4th digit. The short flexor crosses the other superficially, and is attached to its ulnar side. The second mass, shorter and smaller than the other, is similarly inserted into the flexor tendon of the 5th digit, blending also with the palmar fascia at its attachment to the sesamoid bone of the 5th digit. C. and L.—283, fig. 2 (£); 284, figs. 2. 3, 4 (f). Extensor carpi radialis longior (supinator longusT) arises chiefly from the lower part of the tendon of insertion of the deltoid on its outer side. It extends a little further upwards, and is connected with the lower and anterior border of the ex- ternal head of the triceps. Between these points a thin slip arises from the humerus. The muscle passes down in its usual position, bridging over the brachialis anticus. It ends at the lower third of the fore-arm in a small tendon, which passes together with extensor carpi radialis beneath extensor proprim pollicis, then through a sheath upon the radius, having a separate compartment, but lying in the same groove with extensor carpi radialis. It lies rather deeper than that muscle, and to its inner side. It is inserted into the semilunar bone of the carpus. C. and L.—274-5 (8); 276-7 (8); 283, figs. 1,2 (8); 284,fig. 1 (8). Extensor carpi radialis brevior arises from the front of the external condyloid ridge. It ends in a strong tendon which
