The -bort and narrow opening of the mouth, the spindle-shaped pharynx, and the globular stomach may be distinctly recognized; in the latter a Y-diaped figure, composed of the three pharyngeal teeth, is found in active movement. The intestine terminates in a fine tube, the anus. The embryo soon begins to grow, and after having attained a length of mm. it encapsulates itself. The larva finally lies in a transparenl sheath which uni- formly Burrounds it. The sheath protect- tl mbryo from external damage, so thai for months in tin- encysted -täte it may retain it- power of further development. Introduced into (be human intestine, after dissolution of its chitin capsule in the -mall intestine, the parasite develops to maturity. I
