The facets for the cervical ribs are about as deep as long. In the anterior part of the neck they occupy nearly the whole length of the centrum, but further back are separated from the anterior border by a short interval. The cervical ribs are somewhat compressed from above downwards, and in some individuals in which ossification is very far advanced Text-fig. 79.

In the young skeleton (R. 2417) none of the arches and ribs are fused with the centra, and the cartilage-covered surfaces for the neura
