Semi-tend inosus. 



There was no trace of an inscription in this muscle. At its origin 

 it fused with biceps and semi-membranosus, and its insertion, though 

 lower than that of the gracilis, was overlapped by the fascia! expansion 

 of the latter. 



,sv ini-membranosus. 



Had a rounded tendon which gave off no expansions to the fascia 

 or to the knee joint. Only in the gorilla did Hepburn find such 

 expansions. 



Psoas parous. 



This muscle was present. It was united with the psoas magnus 

 at its upper end, and was tendinous for H inches above its insertion 

 into the ileo-pectineal line. 



Psoas ma(/nus. 



Its muscular fibres were intimately united with those of the 

 iliacus for nearly the whole length of the muscle. 



Sartorius. 



Was attached to the anterior border of the ilium lower down than 

 in man, between the iliacus and scansorius. It had the usual oblique 

 course across the front of the thigh to reach the inner side of the knee, 

 where it was inserted superficially to the tendons of gracilis and semi- 

 tendinosus. From its upper border near its insertion a fascial expansion 

 was sent off over the knee joint, 



Ili'i-tus femoris. 



In my case there was apparently only a single head of origin. 

 Corresponding to the second head in man, however, a few fibres were 

 observed to pass from the margin of the acetabulum to join the main 

 head. Hepburn found the origin of the rectus double in all anthro- 

 poids except the gibbon. 



Pectineus. 



Was a very narrow muscle, being only about H inches wide at its 

 origin, which extended from the ileo-pectineal eminence to the origin 

 of adductor longus.
