The scolex is seen obliquely, the left central sucker facing the observer. The right ventral canal, having reached the base of the suckers, also bends over dorsally and horizontally, running to the right dorsal sucker, then it ascends the median internal face of the right dorsal sucker and runs almost the whole length of the sucker, veering over more and more to the right until it at last appears on the dorsal summit of the sucker ; then it turns over, descends parallel to the direction it came, until the base of the sucker is again reached ; it now turns and runs horizontally through the scolex, remaining exterior to the dorsal canal but interior to its first horizontal winding ; arrived at the median internal base of the right ventral sucker, it ascends and descends its internal ventral side, reaching the height of the opening of the sucker. Passing around the base of the right ventral sucker on its posterior surface, it ascends the outer angle of the two right suckers ; at about the same level as the left canal branches, the right canal does the same, but unhke the left canal, it sends off two ramifications, one to the outer surface of the dorsal, the other to the outer surface of the ventral sucker. After the branches have been given off, it ascends almost to the summit, bends over laterally and inwards, descends in the inner angle of the right suckers until the cross commissure is reached ; here it turns inwards, passes under the nerve commissure, then proceeds
