Often morethan half of the length of the parasite is in the last segment; from timeto time the large link is thrown off, so that is is not uncommon to find butthe three proglottides. The worm is short lived, and is probably theleast prolific of the cestodes; this is compensated for by the proliferativepower of the parasite in the juvenile or larval stage. The anterior seg-ment, or scolex, is surmounted by four suctorial discs, anterior to which,between the quadrately placed sucking discs, is the rostellum, with itsbooklets, numbering from thirty to forty. The adult worm is not foundin man. The ova thrown off by the parasite, entering the alimentarycanal of man and some lower animals, hatch the embryo, which, wa
