In the Stellenbosch specimen the centra of the sacrals are not so much constricted as Watson found in the type material in the British Museum. Genus Anthodon. (Text-fig. 7.) In the specimen from Dunedin (, No. 10074) there is preserved a dorsal vertebra, sacrals, and caudals. The dorsal is small (slightly. a b c Text-fig. 7.—Anthodon serrarius. , No. 10074. x J. a = anterior view. b = posterior view. c= lateral (left) view. greater than \ of Bradysaurus), comparatively light; the spine is low and fairly slender; the transverse process is situated high up on the arch and the articulatory surface is short. On the whole, the vertebra is very similar to those of Propappus parvus. The centrum is noto- chordal with an hour-glass shaped perforation. Short Discussion.—If we are correct in stating that the Pareiasaurs possessed 5 cervicals this fact would indicate a definite advance from the primitive embolomerous condition where the neck at most consisted of 2-3 vertebrae; and they would occupy an intermediate.
