It consists of a continuous ischio-pubic bar, extending from one acetabulum to the other, and usually prolonged dorsally above the acetabulum by an iliac process. In all fishes the pelvic girdle is free from the vertebral column, but in the tetrapoda, where the limbs have to support the body weight, the girdle becomes connected with the sacrum by the intervention of one or more sacral ribs (p. 56). In the interpretation of some of the pelvic elements there is some uncertainty. In the stegocephals ischium and ilium and usually pubis were distinct bones with appar- ently considerable cartilage between them. In.
