This specimen is cut in serial sagittal sections, but is, however, rather poorly preserved. There are 37 primitive vertebrae, the last one being incomplete. Caudal to this is a long non-vertebrated tail portion. There are 33 spinal ganglia, the last 2 having slender nerves which, with the thirty-first, form the caudal nerves. These extend caudally along each side of the tail. | This specimen is cut in serial sagittal sections, but is, however, rather poorly preserved.
