Two Hnes are frequently encountered on the upper surface of the levator ani. The more constant of these is the arcus ten- dineus fasciae pelvis. It stretches from the postero-inferior border of the pubic bone and symphysis to the ischial spine. The writer regards this as a thickening of the fascia which covers the upper surface of the levator ani muscle. It serves to fix the bladder and prostate to the wall and floor of the pelvis. Derry ('07) states here: "In this way the pubo-prostatic and lateral true ligaments of the bladder are ; I believe his interpretation entirely correct. This line serves to join in- timately the fascia of the superior surface of the levator ani with the bladder sheath and has been the basis for the erroneous.
