Abnormal insertion of pectoralis minor (left). 



The tendon of insertion passed over the coracoid process in a 

 well-defined groove, giving a slip to the process as it passed to be 

 inserted into the capsule of the shoulder- joint. The outer margin of 

 the tendon was very clearly defined, and lay on a line drawn from the 

 posterior border of the greater tuberosity to the middle of the 

 coracoid process. In such cases the coraco-humeral ligament is said 

 to be weak or absent, but in this case it was very strong and well 

 marked.
