With anterior and pos- terior ends of sacrum reversed, jjft, imliic process ; is, ischiac process ; ac, acetabulum ; b, c, d, sacral ribs ; /, /', foramina. One tenth natural size. After Maish. with very rugose surface. This was present in No. 84 and in the American Mu- seum skeleton. The Fourth Sacral.—Pleuro-central cavities not so deep and centrum less con- stricted inferiorly than in the three i)receding true sacrals. Rather long and strong sacral ribs spring from either side of the centrum and unite by suture with the pos- terior blades of the ilia. They do not coalesce with the sacral ribs of the true sacrals nor do they come in contact with the neck of the ilia in such manner as to take part in forming the acetabulum. The neural spine is free and there is a broad diapophysial process formed as in the true sacrals by the union of branches from the superior blade of the diapophysial lamina of this and the preceding vertebrte.
