In the genital fold, extending from the caudal end of the ovary to the genital cord, connective tissue and smooth muscle fibers developing form the proper ligament of the ovary. The uterus develops in the genital cord so the liga- ment of the ovary extends to the posterior surface of the uterine wall. In the male the homologue of the proper ligament of the ovary is the ligament of the testis. In both sexes the inguinal fold extends from the urogenital fold to the crista inguinalis, located on the inside of the ventral abdominal wall, a point which marks the future entrance of the inguinal canal. The inguinal fold thus forms a bridge between the urogenital fold (in the middle portion of which the uterus develops in the female) and the abdominal wall at the entrance of the inguinal Diaphragmatic bo. of mesonephros' Afetanephros Ureter Chorda, . gubernaculi.

The right suprarenal gland has been removed to show the metanephros. canal (Fig. 225). In the inguinal crest is differentiated the conical anlage of the chorda gubernaculi, which later becomes a fibrous cord. The abdominal muscles develop around it and the external oblique muscle leaves a foramen, through which it connects with a second cord termed in the male the lig. scroti, in the female the lig. labiate (Fig. 226). The chorda gubernaculi and the lig. labiale together constitute the round ligament of the uterus, as they form a continuous cord extending from the urogenital fold to the base of the genital tubercle. With the development of the uterus in the urogenital fold, the round ligament becomes attached to its ventral surface. Male.—The ligamentum testis, like the Kg. ovarii, de
