i The anterior pubic ligament is not mentioned by the author. It consists of two parts, a superficial and a deep. The deep /><irt, which 

 is not shown in any of the figures, is made up of fibres passins tr.insver-ely from bone to bone in front of the interpubic disc ; the fit

superficial part are oblique, interlace freely, and are mainly derived from the tendons of the external oblique and rectus muscles ol the 

 abdomen, as well as from those of the superficial adductors of the thigh. The 

 anterior pubic ligament are shown in both the figures on this page. TK.

" This ligament is a portion of the deep perineal fascia or triangular ligament of the urethra. The name of transverse ligament
