“ The portio vaginalis projects but slightly into the vagina, and the os uteri externum appears as a small rounded opening. The cervix is comparatively long and wide, and the folds on the mucous membrane of the cervical canal are fully formed. The body of the uterus is imperfectly developed, triangular in shape, with thin walls; it is shorter than the cervix, and its interior is marked by folds of mucous membrane converging towards the os. In these cases menstruation is absent or scanty; the other reproductive organs, including the breasts, are usually in a state of arrested development. ”
