The liver appears as a blind diverticulum of the gut, on the right side in most views. The otocysts are more ovoid in shape, and the notochord reaches forward to them. It has a downward flexure at its anterior end and shows signs of vacuolation. The third pair of sense organs, or nasal pits, is now indicated. Three diverging lines on the ventral surface of the brain indicate the lateral ventricles. The pectoral fins are outlined, and delicate protoplasmic.
