The proximal half is stoutlybuilt and leads to a crest formed in the middle of the bone, directed sidewaysand forwards. The distal part of the bone is slender and tapers off to the articu-lation with the pes. Both proximal and distal ends are incomplete and thepreserved length of the bone is 176 mm. Pes The pes (Figs 4C, 6, 11K) is seen in ventral view, the bones being eithereroded or indicated by bone impressions. The calcaneum is incomplete laterally,and probably extended out slightly farther than shown. The astragalus istransversely elongated, with a rounded anterior surface curving back to the 130 ANNALS OF THE SOUTH AFRICAN MUSEUM. Fig. 4. Anchisawas capensis (Broom), SAM-990. A.

Both calcaneum and astragalus are pre-served as impressions, both approximately 15 mm long. Two small distal tarsal elements are preserved, probably nos 3 and 3 is no more than a bony nodule, while 4 is more robust with posteriorand medial surfaces at right angles to each other and a convex anterior surfacefacing metatarsals IV and V. The considerable space between the astragalusand the proximal ends of metatarsals I and II suggests that the two distaltarsals are laterally displaced. All five metatarsals are preserved, in several cases as somewhat imperfectimpressions. There is the usual overlapping of the proximal ends with eachmetatarsal slightly underlying its medial fellow. Metatarsal V is short andnarrow b
