MR. A. SANDERS ON LIOLEPIS BELLI. 



[Feb. 6, 



tured to name this muscle obturator externus : as the ischio-pubic 

 foramen represents the obturator foramen, so the muscle arising from 

 its external surface must represent the obturator externus muscle ; 

 and the fact that its tendon is inserted into the outer part of the femur 

 strengthens that position. 



Iliacus (fig. 10) arises from the anterior edge of the ischium and 

 from the posterior surface of the pubis ; the fibres converge, and are 

 inserted into the summit of the trochanter of the femur. From its 

 position I should imagine that this process corresponds to the tro- 

 chanter minor, and the muscle in question to the iliacus ; for the in- 

 sertion and direction of the fibres (which are the most important 

 points) are the same as in anthropotomy. 



Iliacus externus (fig. 10) appears as a detached segment of the 

 last ; it arises in conjunction with the pelvo-tibialis, and is inserted 

 into the distal portion of the trochanter between the insertion of the 

 last and that of the pyriformis.

Superficial muscles on the dorsal aspect of the thigh. 



Flexor tibialis (figs. 10, 12, 13) arises partly from the anterior 

 point of the symphysis pubis and partly from a fibrous raphe which 

 extends backwards from that point over the dorsal surface of the os 

 pubis ; it is inserted into the aponeurotic expansion from which the 

 pelvo-tibialis arises.
