In the collection of the South African Museum there are 37 femora of which some are only represented by one of the two ends. Although there are about an equal number of femora and humeri it is noteworthy that only in 8 specimens there are preserved both a humerus and a femur of the same individual. The femur of the Anteosauria differs so markedly from that of the Tapinocephalia and the Titanosuchia that in this general account of the Deinocephalian femur it is not considered, but is treated of separately in the systematic part of this paper. The femur, always longer than the humerus, is a massive bone with very little of a shaft but with expanded ends. The proximal end is always wider than the distal end. There is a very little "twist" on the shaft so that the two ends lie in nearly the same plane, but the distal pre-axial condyle does lie a little more ventrally than the distal post-axial condyle. The post- axial condyle also lies a little further distally (where it lies much distally this appears to be due to postmortem deformation or is pathological). The shaft is always much broader than thick. In dorsal view the pre-axial border is more concave than the post-axial border. In pre-axial view the ventral border is more con
