The right Wolffian body, still a very voluminous organ in this stage, is shown divided near its caudal extremity to exhibit the renal metanephric bud situated on its mesal aspect and ventrad of the aorta. The ureter appears as an outgrowth from the dorsal wall of the Wolffian duct near its cloacal termination, turning dorsad to its engagement in the mass of the renal cellular mesenchyme. Wolffian duct and ureter possess a short and relatively wide terminal segment, already in the process of opening out to be included in the genito-urinary sinus. The end gut is still connected with the cloaca by a narrow channel, formerly described as the "stalk of the allantois," but the separation of the primitive urogenital and intestinal compartments of the cloaca has nearly been completed.
