THE MUSCULATURE OF THE TRUNK. 305 



evidences of the lines transversce, so familiar to us in 

 many of the Mammalia ; and Owen also found them 

 to be present in the Kiwi-kiwi. 



147. The transversalis abdominis 1 is a very well- 

 defined muscle in the Kaven, and is seen to arise, 

 thin and tendinous, from within the entire post- 

 pubic and iliac margins of the pelvis ; and to some 

 extent from the inter-pubic ligament. Becoming 

 gradually carneous, its fibres pass across the abdomen, 

 between the peritoneum, the rectus, and the internal 

 oblique, to become inserted over the entire pleural 

 aspect of the last two vertebral ribs, the intercostal 

 muscle between them, and the same surfaces of the 

 hseinapophyses connected below. This part of its 

 attachment is semitendinous. Its abdominal insertion 

 is into the linea alba, which just before reaching, the 

 transversalis becomes completely aponeurotic. This 

 aponeurotic area of the transversalis abdominis, when 

 taken in connection with the similar area of the muscle 



1 That patriarch in anatomy, Aldrovandi, gave a striking name 

 to this muscle, as may be seen in the subjoined synonymy from 

 Gadow (loc. cit., p. 128) :
