This constitutes the condition designated by Mayer the uterus bipartltus. The concomitants of this condition may be a short vaginal cul-de-sac, together with rudimental Fallopian tubes, and perhaps well developed ovaries. In the latter case the external organs may be well formed, and there may be no deficiency of sexual charac- ter, or the vagina may be entirely wanting. The coexistence of this rudimental uterus with ovaries well developed is easily ex- plained.

For the ovary is formed out of a separate portion of blastema from that from which the Wolffian bodies and excretory duct of the generative apparatus are developed,_/%. 400. and 416., so that the failure in growth of the one does not necessarily involve a cor- responding defect in the other. Group II. If one uterine cornu retains the imperfect condition last described, while the second undergoes development, the one- horned uterus or uterus unicornis is produced. So that the organ here consists of a developed and an undeveloped half combined. The developed uterine horn may be either the left or the right. It then consists of a cylindrical or fusiform canal or body, curved outwardly in the form of an arch which ex- hibits various degrees of deflection from the meridian. To its upper extremity is usually attached a tube leading to the seat of a well- formed ovary. The second or undeveloped cornu, with its tube, is not always entirely deficient ; but there often exists a rudiment in connexion with the developed horn, which, according to the degree of malformation, is either solid or hollow, or is traversed by a canal opening into the cervix of the developed half. In the case of the uterus unicornis, notwith- standing the imperfection of one uterine half, both ovaries may be found alike developed. The type of this condition of uterus exists as a normal formation in the class ave
