The vertebrae consist of cervicals, dorsals, caudals and some from the sacral region. The anterior dorsals are keeled below, in the dorsal series the angularity gives way to a rounded lower surface, the sacrals are depressed and the caudals, early in their series, become laterally compressed. The posterior, inferior ends of the caudal centra present facets for chevron bones; in one anterior caudal, in particular, they are conspicuous with a pronounced enlargement of the centrum in their vicinity. In most of the dorsal vertebra3 the neural arches have become detached, in the caudals the base at least is generally intact. The zygapophyses are well developed. The articular faces of the centra in the caudals are slightly concave, those of the dorsals are plane. There is a considerable variation in the size of the vertebraj. It is altogether probable that more than one species is represented. The following measurements in mm. are taken from a number of centra found with others within a limited area: [table omitted] A large dorsal from Mackay creek has the following dimensions: length of centrum, 27'0 mm., height of articular face, 220 mm., breadth of articular face, 23"0 mm.
