rough and convex, the under and outer smooth and concave. A rounded promi- 

 nence, the conoid tubercle, for the conoid ligament, is situated on the top of the first 

 part and rather to the inner side, just above the angle formed by the two parts. A 

 ridge from behind this, running outward and forward, separates the two parts dis- 

 tinctly. The trapezoid ridge for the trapezoid ligament runs forward from the conoid 

 tubercle along the inner side. The outer side of the upper aspect has a ridge for

the coraco-acromial ligament. The short head of the biceps and the coraco- 

 brachialis arise from a roughness at the tip of the process, and the pectoralis minor 

 inserts into one at its inner side. 



The anterior surface, or venter,' is concave, forming the subscapular fossa^ 

 the deepest hollow being along the origin of the spine. At the very top the bone 

 often takes a turn outward. The serratus magnus is attached to rough surfaces 

 inside the upper and lower angles and to a narrow line connecting them just beside
