In embryo No. {{CE875}} there are 34 vertebra?. The last is small and contains the winding part of the chorda dorsalis. The spinal cord narrows between the thirty-first and thirty-second vertebrae, as shown in figure 20. Its caudal end expands slightly and the extreme tip enters into the tail-bud. On the ventral wall of the central canal there are a few small folds. Near the caudal end of the vertebral column is a long, solid strand of cells, similar in structure to the cells of the spinal cord, which may have become separated from the latter at an earlier stage. Dorsal to the thirty-third and thirty-fourth vertebrae is a small papilliform tail, which is non-vertebrated and contains the caudal end of the vessels and a group of cells representing a remnant of the caudal end of the spinal cord. There are 31 spinal ganglia with nerve-fibers. The coccygeal tubercle and post-anal swelling are distinctly evident. | |||

In embryo No. 875 there are 34 vertebra?. The last is small and contains the winding part of the chorda dorsalis. The spinal cord narrows between the thirty-first and thirty-second vertebrae, as shown in figure 20. Its caudal end expands slightly and the extreme tip enters into the tail-bud. On the ventral wall of the central canal there are a few small folds. Near the caudal end of the vertebral column is a long, solid strand of cells, similar in structure to the cells of the spinal cord, which may have become separated from the latter at an earlier stage. Dorsal to the thirty-third and thirty-fourth vertebrae is a small papilliform tail, which is non-vertebrated and contains the caudal end of the vessels and a group of cells representing a remnant of the caudal end of the spinal cord. There are 31 spinal ganglia with nerve-fibers. The coccygeal tubercle and post-anal swelling are distinctly evident.
