or metacromion. The anterior or coracoid border of the 

 scapula is continuous with a coracoid process projecting 

 inwards. It represents a vestigial portion of the precoracoid 

 bone. 



The humerus has a 

 large head and two 

 prominent tuberosities. 

 Distally it moves in the 

 trochlea or articular sur- 

 face of the fore-arm, 

 above which is a small 

 supratrochlear foramen. 

 The radius and ulna 

 are distinct but closely 

 united to allow of no 

 pronation. The fore- 

 limb is permanently 

 supinated. The ulna is 

 produced back beyond 

 the radius to form the 

 olecranon process. 



The carpal bones are 

 nine^ closely bound to- 

 gether by ligament. The 

 proximal carpals consist 

 of scaphoid, lunare and 

 cuneiform, and a small 

 sesamoid {pisiform), 

 together with a small 

 centrale. The distal 

 carpals are the trapezium^ 

 trapezoid, 7nagnum and 

 unciform. 



There are five meta- 

 carpals^ each bearing a 

 digit. The first digit has two phalanges and the others 

 three. 



The pelvic girdle has large ilia which run backwards to 

 the acetabulum. The pubes are united ventrally to the 

 ischia, thus enclosing on each side a large obturator foi^amen. 

 The symphysis is pubic only.
