. Bulletin of the British Museum (Natural History), Geology. AFRICAN PLIO-PLEISTOCENE 51 those of the modern arboreal and semi-arboreal genera, and also than Papio, agreeing in relative size with those of Theropithecus gelada. Cuneiform II is represented by three specimens. One of these, from the left side (KNM-OG 1479), is intact apart from some damage in the region of the tuberosity, and the details of the articular surfaces can be clearly distinguished. The distal surface is deep relative to its breadth, and is approximately symmetrical about its long axis, the condition also seen in Theropithecus gelada, among modem genera. In those forms which have a larger hallucal metatarsal, and hence a more extensive 'beak' on the first cuneiform, the medial margin of the proximal face of the second cuneiform is much longer than the lateral, in order to support the large 'beak'. The morphology of the lateral surface shows no remarkable features, but that of the medial surface reflects the reduction of the 'beak' of the first cuneiform in the rela- tively very small size of the anterior articular facet; this is much less in anterior- posterior diameter than the interval separating it from the posterior facet (Fig. 12)..
