The female genital organs are similar in arrangement to those of F. falcata. The vagina runs forward and dorsally for a distance of about 2 mm. from the vulva, gradually expanding into a thick-walled muscular chamber with a maximum diameter of 0'45 mm. It then gives off two opposed uteri. The anterior uterus runs forward to a point about 3 mm. from the junction of oesophagus and intestine,.
