Fig. 1. Fragment of a large right os innominatum. The faint T-shaped lines in the acetabulum indicate the limits of the three component pelvic bones; fig. 1 is placed at the posterior border of the ischium. =J=._b_.10, no. 1. 2. Imperfect right os innominatum, with the anterior and posterior wings of the ilium broken away. =J=._b_.10, no. 4, p. 69. 3. Imperfect left os innominatum showing the small obturator foramen which divides the pubis from the ischium. On the anterior border of the pubis is seen a depression, which may have given attachment to the prepubic bone. =J=._b_.10, no. 3. 4. Visceral aspect of an imperfect right ischium. =J=._c4_.20.2. ------------------ 5. Exterior side aspect of a right femur. =J=._c2_.11. 20. 6. Front aspect of the same specimen, p. 62. 7. Posterior aspect of proximal end of right femur of a different genus, showing a pit for the obturator muscle. =J=._b_.11, no. 1. 8. Front aspect of the same specimen. 9. Outline of the proximal articular end; the obturator pit is darkened. 10. Posterior aspect of distal end of right femur. =J=._b_.11, no. 20. 11. Outline of the distal articular end of the same specimen. 12. Distal end of a large right femur. =J=._b_.11, no. 12. ------------------ 13. Proximal end of tibia (? front aspect). =J=._b_.12, no. 8. 14. Another view of the same specimen, p. 62. 15. Outline of the articular aspect of the same tibia. The non-articular part is shaded. ------------------ 16. Claw phalange. =J=._c1_.2.5, p. 69. 17. Claw phalange. =J=._c_.9, no. 4. PELVIS, FEMUR, TIBIA, &c. Pl. 8. [Illustration] PLATE IX. Neck Vertebræ. Fig. 1. Anterior aspect of an axis to which the atlas was not anchylosed. =J=._c3_.15. 2, p. 64. 2. Anchylosed atlas and axis seen from the base of the vertebra. =J=._c_.1, no. 8. 3. Anchylosed atlas and axis seen from above. =J=._c_.1, no. 14. 4. Atlas, neural arch imperfect. =J=._c_.1, no. 10. 5. Anchylosed atlas and axis seen from the side, the neural arch of the atlas is wanting. The light space in the centrum of the axis is the pneumatic foramen. =J=._c_.1, no. 14. ------------------ 6. Large cervical vertebra seen from below. =J=._c_.2, no. 42, p. 65. 7. Small cervical vertebra seen from below. =J=._c_.2, no. 43. 8. Cervical vertebra seen from behind. =J=._c_.2, no. 5. 9.
