. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. PELVIS. 155 the anterior pelvic outlet, the transverse dia- meter is a little larger than the antero-pos- Fig. Pelvis of the Lion, side view. terior, and the acetabula are large and deep. In the Badger the ilia and ischia are large, expanded, and curved outwards at their free extremities. The iliac shaft is prismatic, with an ilio-lumbar angle of 140°. The pubes are rather long, with an elongated symphysis, and form an angle with the ilia of about 130°. The same general conformation is evident in the Racoons and Coatis, the ilio-ischial angle being, however, somewhat better marked, and the ilio- pubic about 145°. The Coatis have but one sacral vertebra. In the Hyaena, also, the iliac wings are considerably spread, with a very pointed anterior spine. In the Dingo the iachio-pubic element is very short, the anterior outlet and obturator foramina small, but the posterior outlet larger. The Weasel has a very small pelvis, with but two sacral vertebrae, one only articulating with upper extremities of the long iliac shafts. In the Pliocce the sacrum has four vertebrae, the first only articulating with ilia, and much wider in its transverse processes than the rest ; the ilia are extremely short, thick, and curved outwards, with very small external fossae; the ischia are long and slender, with small tuberosi- ties almost touching the second coccygeal ver- tebra, with long rami not forming a symphysis, but directed backward to meet the pubis. The jnibcs are very long, slender, and oblique, with a short symphysis, and including a very large, oval obturator foramen. The pelvis altogether somewhat resembles that of the Badger, with the superior opening much elongated antero- posteriorly, and triangular in shape, with the base at the sacrum. The shortness of the ilia alone indicates the great contraction of the posterior extremities for their swimming re- quirements. Dr. Knox has observed, in a pr
