In the section of Fig. 8 c the organ of fixation is much wider. There are a few roots in the ventral nerve cord, some in or against the musculature under the cuticle, and some against another muscle (in the right side of the figure). In Fig. 8^ the ventral nerve cord is connected by a strand of tissue to the musculature covering the body wall. The parts of the parasite are not very different from those shown in Fig. 8c. One of the roots, in the peripheral region of the ventral nerve cord, is sectioned more or less longitudinally. In the section shown in Fig. 8e the ventral nerve cord is connected to the body wall by a broad mass of tissue. The organ of fixation of the parasite here is already comparatively wide. There are a few roots of large size and a great number of smaller roots.
