Natural size. , (GC 87 65, 100. 108 E, 118 A, 123 C & 152) (Fig. 20) Left Six fragments conjoin to form a portion of the diaphysis of a left radius. The diaphysis preserves only a small portion of the volar surface along the medial side from just inferior of the radial tuberos- ity to distal of midshaft, as well as some volar surface in the distal metaphyseal region. Virtually the entire medial surface, preserving the interosseous crest, is present from just distal of the radial tuber- osity to the distal metaphysis. Dorsally, only the medial side of the proximal shaft is preserved, but the dorsal surface is largely complete from the region of midshaft to the distal metaphysis. None of the distal articular surfaces are preserved, but the medial-most dorsal (Lister's) tubercle is preserved. The lateral surface of the shaft is present only in the region of midshaft, where it preserves a portion of the M. pronator teres insertion, which is well defined and rugose. In size and morphology this specimen matches (above), and probably represents its antimere. (GC 1949-51 Level 13) (not figured) Right This specimen preserves of a right radial diaphysis. The fragment preserves a portion of the interosseus crest and the distal end of the anterior ridge (the ridge that extends disially from the radial tuberosity and gives rise to the radial head of M. flexor dlgitorum superficialis). The proximal portion of the shaft preserves some of the lateral and dorsal surfaces, while distally onh the medial and dorsal surfaces are preserved. Morphology Little can be said about the comparative morphology of the Gough's Cave radii, since muscle scars and articular surfaces are poorly represented. The five Creswellian radial remains described above may all derive from a
