M, Muellerian duct; W, Wolffian duct; A, location of normal metanephric anlage; B, possible upwardly displaced meta- nephric anlage; D, extended ureter merging into the Muellerian duct at [/; N, portion of Wolffian duct taken into wall of urogenital sinus; UgS., cross-hatched portion of Wolffian duct degenerates. If in this particular case, however, the ureteric anlage did not develop low enough to be included in that lower portion of the mesonephric duct then just as soon as the normal degeneration of the upper part of the Wolffian duct occurred, the upwardly displaced anlage (B) which developed into the ureter was without connection with the urinogenital sinus. Being thus isolated it seems probable that the ureter (D) extended to the nearby Muellerian duct and merged into it at (U). This established an outlet into the urinogenital sinus. The above is ofTered as one possibility to which the present anomaly may be due. It is entirely hypothetical as any con-.
