96 THE MYOLOGY OF THE RAVEN. 



from a small circular origin .situated at the postero- 

 mesial aspect of the shaft of the coracoid, immediately 

 above the fossa which harbours the insertion of the 

 subclavius. Its fibres pass almost directly upwards 

 parallel with the coracoidal shaft, and as they near 

 the head of the humerus they again become tendin- 

 ous, and are finally inserted on the top of the ulnar 

 tuberosity, on a diminutive subcircular space, common 

 to it and the insertion of the teres minor. 



Owen tells us that " This muscle is wanting in the 

 StrutliionidcB, is of small size in the Heron and Goose, 

 is much more developed in the Raptores and many 

 Natatores, especially the Penguins, and attains its 

 greatest relative size in the Rusores, where it arises 

 from almost the whole of the coracoideum." 



62. Tlie teres minor '^ arises fleshy from the under 

 side of the anterior tip of the scapula, the clavicular 

 process of the bone, to the extent shown in Fig. 8. 

 The fibres, forming a chunky, little muscle, pass 

 directly outwards, behind the coracoidal head, and 

 beneath the neck of the scapula. Clearing these two 

 bones the fibres rapidly converge to form a small 

 tendon, which is intimately fused with the tendon of the 

 coraco-brachialis, and consequently makes the same 



von zwei Muskeln, die am Os coracoideum entspringen und am 

 Humeruskopfe sich inseriren ; das siiid die beiden hier als 

 C oracohrachiales beschriebenen Muskeln. Tiedemann fiihrt einen 

 Deltoideus minor und Levator humeri auf, dei zum Theil wenigstens 

 dem Coracobrachialis brevis entsprechen. Auch Gurlt, Wiedemann, 

 Merrem, Aldrovandi erwahnen den Muskel nicht " (Bronn's 

 Klussen des TJiier-Reichs, vi. Band, p. 115). 



^ Possibly this muscle corresponds to the subscapularis intermis 

 of Gadow's " 72b. M. subscapularis," and attention is invited to 

 the muscle I desci-ibe below as the sid>scapularis (No. 65), and the 

 footnote under it.
