Taenia Solium, Or Pork Tapeworm, is usually about 3 meters long, with from 800 to 900 segments. The head has a rostellum armed with a double row of from 26 to 30 hooklets and four suckers on the sides. The uterus consists of a median tube, with from 6 to 12 coarse lateral tubes. The genital pore is on alternate sides of the segments, which, when mature, are longer than they are broad.

The eggs are oval, about 30 to 35 µ in diameter, and consist of a peripheral striated zone and a central granular portion in which can be seen six lines representing hooklets. The embryos occur in pork as measles, and as Cysticercus cellulosae in the muscles, brain, and eye of man. They gain entrance in uncooked pork.
