In internal organization, the presence of an internal circular muscle at the beginning of intestinal region, the division of the anterior por- tion of alimentary canal into esophagus proper and stomach, the open- ing of the ciliated canals leading from cerebral sense organs into shallow lateral pits (text fig. 22, cp') In place of cephalic furrows, the absence.
