The an- terior end is extremely small, terminating in a knob called the head. The body enlarges gradually backwards, and it is broadest at the extreme hind- end. It is produced anteriorly into a process or rostelliim which bears a ring of (22-32) hooks and behind them there are four large suckers. A little way behind the head there appear transverse con- strictions running across the body. These get wider apart and deeper towards the hind- end, and partially divide the body into a series of sections known as proglottides. There may be about 850 proglottides, of which the broadest are about \ inch across. There is no mouth, no ali- mentary system, and no sen- sory organs, but the nervous and excretory systems are well developed. There Nervous, . ^ .
