The spines are fused to form a median crest, which is notched, however, between the summits of the spines. On either side are two tubercles, vestiges of the fused articular processes. The pelvic surface is deeply concave and presents two pairs of foramina. The wings are prismatic and very high. Their lateral surfaces are extensive, face almost directly outward, and bear an auricular surface on the lower part. The anterior surface of the body of the first vertebra is extensive, depressed in its middle, and bears a prominent lip below. The anterior articular processes are large and have extensive, slightly concave facets which face dorso-medially. The posterior articular processes are small. The transverse processes of the last vertebra project backward and may articulate or fuse with those of the first coccj-geal. The sacral canal is strongly compressed dorso-ventrally. The coccygeal vertebrae are fully developed in the anterior part of the region. The arch is complete in the first six usually. The first three or four have well de- veloped articular processes at each end. Behind this the posterior processes quicldy disappear, and the anterior ones become non-articular and gradually re-.
