The pro-glottides increase gradually in size, mature ones measuring 10 to12 mm. in length by 5 to 6 mm. in breadth. The uterus iscomposed of a median stem with 7 to 10 lateral branches on eachside. The eggs are globular, 30 to 36 microns in diameter, theshell radially striated, and the oncosphere contains 9 hooks. The symptoms of infestation with the pork tapeworm do notdiffer from those of the beef tapeworm. The anatomic differ-entiation has been made under Tcenia saginata. The length of life of the pork tapeworm is not definitely kno
