In the male, the Wolffian duct persists, and forms the tube of the epididymis, the vas deferens, and common ejaculatory duct, while the seminal vesicle arises as a lateral diverticulum from its caudal end. The cephalic Wolffian tubules form the rete testis, vasa efferentia, and coni vas- culosi of the testis; while the caudal tubules atrophy or are represented by the occasional vasa aberrantia of the globus minor and by the paradidymis. In the female, the Wolffian bodies and ducts atrophy. The remains of the Wolffian tubules are represented by the epobphoron and the paroophoron (p. 1407), while the cephalic portion of the Wolffian duct sometimes persists as the functionless duct of Gartner (Fig. IISI)..
