over the transverse perineal muscles, it blends with the posterior border of the tri- 

 angular ligament along the perineal shelf ; laterally, it is attached to the ischial and 

 pubic rami ; and in front it is prolonged over the labia majora to become continuous 

 with the corresponding fascia (Scarpa's) over the abdomen.

The fascia of Colles forms the lower boundary of the superficial perineal inter- 

 space, a triangular pocket limited above by the inferior layer of the triangular liga-
