Buccal, occlusal and posterior views of the Machairodus sp. mandible (L 20505) from Langebaanwcg. supporting the protocones are anteriorly directed, their dorsoventral axes being in line with the apices of the paracones. Although the C and P3 of this specimen show no obvious signs of wear, the shearing surfaces of the P4 para- cones and metastyles are heavily worn, while the protocones have been all but worn away. The lingual surfaces of the parastyles and ectoparastyles are also slightly worn. The preserved right M1 is also worn and little of the crown remains. It is single-rooted, but has a slight transverse elongation. The alveolus of the missing left M1 shows vestiges of the more primitive double-rooted condition. Little remains of the skull itself and the dorsal edges of the preserved parts are heavily abraded. The largest piece of the skull which is preserved consists of that part of the basi-cranium which includes the glenoid regions and the intervening basi-sphenoid. The glenoid fossae are approximately 13 mm below the level of the basi-sphenoid, the relative positions of these features being characteristic of the machairodonts. In the modern feline skulls used for com- parative purposes during the present study the glenoid fossae and basi-sphenoids.
