Scapula. The scapula is symmetrically fan-shaped, the superior border 

 regularly rounded. Viewed from above the superior or suprascapula border 

 is slightly sinuous, being feebly sigmoidal. The cartilaginous portion is 

 wanting. The glenoid border presents an oval outline, with the antero-pos- 

 terior diameter one-fifth greater than the transverse. The acromion process
