A detailed drawing sent us by Mr H. P. Powell allows us to make a more complete description. It has a breadth of 87 mm and a height of 62 mm, an H:B index of 71. The anterior view shows a 330 slope of the medial edge of the dorsal process. This edge is concave and slopes but 260 at the base. It has a long, low, rounded medial condyle and a fairly sharp ventro- lateral border of the lateral condyle. The dorsal edge of the calcaneal border is set forward of the dorsal process and has a rounded dorsolateral projection. The dorsal process is separated from the anterior surface by an upper horizontal groove that fades out medially. There is no deep pit for a process of the cal- caneum as in Allosaurus, but there is a concave edge for the calcaneum. A slight lower horizontal groove runs about a quarter of the way inward from the centre of the medial condyle. The lateral view shows a high calcaneal facet with the upper horizontal groove at the base of the dorsal process separating the rounded anterodorsal projection. The posterior foot below the tibia is bluntly rounded behind and becomes longer anteroposteriorly on the inner side. The striking features of this view are the strong posterodorsal projection above the lateral condyle and the upper horizontal groove above and behind Please note that these images are extracted from scanned page images th
