Fig. 2. External aspect of a maxillary tooth from the Tamboer specimen ; naturalsize. Fig. 3 and fig. 4 are from the jaws of Pareiasaurus Russouun from the top of theNieuwveldt range, midway between Klip-fontein and Fraserberg; naturalsize. Fig. 3 is the external aspect of a maxillary tooth, with the denticles nearly on thesame level, and the tooth flat; natural size. Fig. 4 is a mandibular tooth from the same specimen seen from the inner side of thejaw, showing the radiating denticles. A successional tooth of similarcharacter is seen below; natural Palate of Pareiasaurus 20. Fig. 1. Palate of the Tamboer specimen referred to Pareiasaurus bombidens, showingteeth scattered in the interspaces between the rows. This palate is con-tinuous with the maxillary bones; w. is an intercentrum below the basi-occipital. Fig. 2. The same palate seen from the side, so as to show the superior and inferiorsurfaces of the bones, and position of the maxillary and mandibular bones. Fig. 3.
