This variety of tape-worm seems to be at once androgynous and hermaphrodite, im- pregnation occur- ring indifferently by means of the ap- proximation of two individuals, or, as is probably more com- monly the case, by that of two joints of the same animal. The hroad tape- worm (tasnia lata, bothriocephalus latus, taenia membranacea) seldom exceeds fifteen feet, though occasionally it attains a much greater length. It is white, flat, from six to ten lines in width at the broadest part, which is near the middle, and consists of a series of concatenated joints, the intervals between which grow suc- cessively longer the nearer they approach the tail. In its general features, it bears a pretty close resemblance to the long variety ; but the articulations are comparatively larger and strong- er ; the flattened surface of each link is perforated by a small hole, and the head of the animal, (Fig. 71, a a,) when seen by means of a lens, is found to be of an elongated, elliptical shape, with a large fissure on each side of it.
