XLV., Figs. 1-7. There is a short pre-pharynx, a small pharynx, about mm. long, a short oesophagus, its walls very strongly muscular and surrounded by glandular cells. The forking of the intestines is thus close to the pharynx, a point different from B. nodulosa. The intestines are simple and long, reaching to near the hinder end of the bod}-. They are lined with epithelium cells whose outer ends are elongate and whose tips extend into the cavity of the organ.
