2. High lateral brachial origin of Brachialis anticus. 



3. Union of Subscapularis and Supraspinatus, beyond cephalic 

 border of scapula. 



4. Large size of the Teres major. 



5. Double origin of Dorso-Epitrochlearis. 



6. Inferior portion of Coracobrachialis.

 accounts for the well developed lateral humeral ridge. 



The Pectoral ridge is also extremely well developed and 

 prominent.
