The iutestiue has a characteristic Y-shape (Fig. IIG), its posterior portiou being prolonged backwards to form a ca^cal pouch, from the extremity of which a band or plate, the funicvhis (Fig. IIG, /'), containing in some cases muscular fibre ;^, and lined by perito- neal cells, arises, and passes backwards to be inserted into the ectocyst posteriorly. The anus (a), as already stated, opens on the anterior surface of the body, outside the limits of the lopliophore, and between it and the mouth lies the nerve-ganglion, which is frequently hollow aud sends off nerves to the various portions of the body 31.
