Anterior end of esophagus set off from spear extension by expansion, about one-third neck width, continuing about this width until it narrows to pass through nerve ring. Esophagus enlarged near middle by gradual expansion. Cardia hemispherical. Prerectum length four times body width. Rectum length about equal to anal body diameter. Ovaries reflexed half way to vulva.
