In the median line a diamond-shaped lacuna separates the pubes from the ischia. The ischia meet in the middle line as a strong symphysis forming a well developed ventral keel. Together they are broader than the pubes and also longer. The postero-lateral corners, although thickened, are hardly tuber-like. The ischium forms a strong posterior rim to the acetabulum.

The Humerus (Figs. 5 and 6) In the holotype of Hipposaurus boonstrai there is a good complete right, humerus and the distal end of the left humerus. In addition I have the distal three-quarters of a larger humerus found unassociated with any other part of the skeleton, which I tentatively identify as that of ?Hipposaurus major. a c f.
