The ischial tuberosity is very strongly turned upwards. The pubic lip is oblique, with the posterior half higher than the anterior. The limb is unknown. Genus Pareiasuchus Broom and Haughton. Pelvis.—The pelvis is small and its con- stituent bones light. It is very low but broad. The breadth is made to appear still greater by . T . ,, . , Text-fig. 47. —Lateral its lowness. In anterior view the inner edge view 0f right half of the is broadly U-shaped. With the sacral ribs in pelvis of Propappus situ the opening is oval, with the lateral dia- Mirror imager meter the greater. Sacrum.—Four vertebrae are concerned in its attachment, and these all have their centra coalesced. Concomitant with the lightness of the pelvis the sacral ribs are also light and comparatively slender. The first is the strongest, and its articulatory surface to the surface anterior to the ridge is large. The other three progressively decrease in size. Ilium.—The ilium is much forwardly directed, with its blade diverging anteriorly. The antero-ventral edge is greatly everted. The posterior iliac process is large and projects far posteriorly, but the ilium is so greatly forwardly directed that it also lies anterior to the vertical plane, passing through the centre of the acetabulum. The iliac blade is long and very low. The outer surface is concave. The iliac shaft is either long or very long and moderately or very much constric
