PLATE X X X I ~ r. The vertebral column of Anoplosaurus c~rto~ot~s. Fig. l. Left lateral aspect of third to seventh cervical eentrums, showing how the bodies of the vertebrae increase in depth from before backward, and indicating at the upper anterior corner of each an attachment for a cervical rib. 1 a. Visceral aspect of third (?) cervical vertebra, showing flattened and rounded under surface, and expansion towards the anterior end. Fig. 2. Left lateral aspect of fourteenth to eighteenth eentrums of the series, showing the somewhat compressed appearance of upper parts of the bodies of the last five dorsal vertebra. 2 a. Visceral aspect of the last dorsal vertebra, 1~o. 18. 2 b. Posterior (?) articular end of the same centrum, No. 18. 3. The sacrum, showing the neural or superior surface, and giving evi- dence of the great expansion of the spinal cord in the region of the second and third sacral vertebra. The outlets for the escape of the sacral nerves at the sides of the centrum are best seen in the first three vertebrae. 4. Dorsal surface of vertebral end of a sacral rib, showing the massive end for attachment to the sides of the centrums of the second and third vertebrm. Its worn upper surface gave attachment to the neural arch. 5. Left lateral aspect of a sequence of six early caudal vertebrm numbered 25 to 30, showing decreasing depth of the centrum posteriorly, and diminishing size in the surface for the attachment of the sacral rib which remains in union with the 30th vertebra. The chevron facet, e, also diminishes in size. 5 a. Posterior articular surface and facet for the chevron bone of the vertebra ~No. 26.
