. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. 154- PELVIS. The ilia are narrow and cylindrical; pubes long, large, oblique, with no ilio-pectineal apo- physis; ischia short, with horizontal raini and tuberosities passing backward to articulate with the transverse processes of the upper coccygeal vertebrae, another bird-like arrange- ment. In the sacral pieces are four, with complete ankylosis, the two or three upper articulating with the ilia. Ilia expanded, with extended crest and external fossa, and reaching to the penultimate lumbar vertebra;; ischia very short, witli more expanded tubers ; jjitbes less oblique. In L. volans, or Galeo- pithccus, the sacrum has five vertebrae, the first only articulating with ilia. Ilia small and narrow ; ischia with large posterior angle; pubic symphysis very short. In the sub- genus Sterops, the slender Loris presents a remarkably elongated and contracted pelvis. The sacrum is long and narrow, with the two upper pieces articulating with ilia. Ilia slender, long and columnar, and nearly parallel with spinal column ; ischia small, flattened laterally, placed in a line with the ilia, and very near each other, so that the cotyluid cavities are closely approximated; the lateral diameters very short, Fig. 93. and the inferior outlet a mere chink. The pubes are long, projecting forwards, down- wards, and inwards, being in- clined to each other at an angle of 40°, causing the superior outlet to be trian- gular, with the base at the inter-cotylaid diameter, and the apex at the symphysis pubis. This pelvis is also remark- able for the extreme angularity of the pubic portion with the iliac, the ilio-pubic angle being 75°, or less than a right angle, the only instance of the kind I have met with.
