The lowest class of Vertebrata, including only the Amphioxus. The heart is represented only by a simple pulsating vessel. The blood is colorless; the brain, renal organs, and limbs are wanting, and the backbone is represented only by a simple, unsegmented notochord. See Amphioxus.
a.
Having the tail fin divided into two equal parts by the notochord, or end of the vertebral column; protocercal. See Protocercal.
n.
One of the primitive masses, or segments, into which the mesoblast of the vertebrate embryo breaks up on either side of the anterior part of the notochord; a mesoblastic, or protovertebral, somite. See Illust. of Ectoderm.
a.
Situated in front of the notochord; -- applied especially to parts of the cartilaginous rudiments in the base of the skull.
n.
The anterior end of the notochord and its bony sheath in the base of cartilaginous crania.
a.
Situated on the ventral side of the notochord; as, the subnotochordal rod.
n.
The inner, or visceral, one of the two lamellae into which the vertebrate blastoderm divides on either side of the notochord, and from which the walls of the enteric canal and the umbilical vesicle are developed. See Somatopleure.

n. pl.
One of the grand divisions of the animal kingdom, comprising all animals that have a backbone composed of bony or cartilaginous vertebrae, together with Amphioxus in which the backbone is represented by a simple undivided notochord. The Vertebrata always have a dorsal, or neural, cavity above the notochord or backbone, and a ventral, or visceral, cavity below it. The subdivisions or classes of Vertebrata are Mammalia, Aves, Reptilia, Amphibia, Pisces, Marsipobranchia, and Leptocardia.
n.
The outer, or parietal, one of the two lamellae into which the vertebrate blastoderm divides on either side of the notochord, and from which the walls of the body and the amnion are developed. See Splanchnopleure.
