These are the first, tenth, eleventh, and twelfth, and sometimes the ninth. The first thoracic ver- tebra resembles the seventh cervical in the shape of its body, and the length and direction of its spine. There is a circular facet on either side of the body for the head of the first rib, and one facet on each side at the inferior border of its body, to com- plete the socket for the head of the second rib. Its trans- verse processes are long, and the superior intervertebral notch is better marked than in other members of the thoracic series. The superior articular surfaces are directed backwards and upwards, not laterally as in the lower members of the series. The ninth thoracic vertebra occasionally has only the upper pair of facets on its body; at other times it conforms to the usual type. The tenth thoracic ver- tebra may have only one complete costal facet on each side for the Xth rib, though sometimes the articular socket may be completed by the ninth dorsal vertebra. The facet on the transverse pro- cess is generally small, and sometimes absent. The eleventh thoracic vertebra has a complete circular facet on the lateral side of each root of the vertebral arch for articula- tion with the Xlth rib. Its transverse processes are short 9.
