Teres major. 



Arose from the inferior angle and lower third of axillary border 

 of scapula. It was joined as above mentioned by a muscular slip 

 from the latissimus dorsi and its insertion blended with that of the 

 latter. 



Subacapidaris. 



As in man. 



Serratus magnus. 



Arose by digitations from eleven ribs. There was no cervical 

 portion. The upper two fascicles were by far the thickest and most 

 powerful. 



Coraco-brachialis. 



This muscle has received a great deal of attention since Wood 

 pointed out the variations that may occur in it. It was divided in 

 my case into two distinct portions (separated by a cellular interval) 

 between which passed the musculo-cutaneous nerve. These two por- 

 tions correspond to Wood's coraco-brachialis longus and medius. 



Biceps. 



The coracoid head was intimately fused with the coraco-brachialis. 

 At the lower end of the muscle a Hat fibrous expansion was sent off as 

 in human anatomy. 



Triceps. 



The long head arose from the axillary border of scapula between 

 teres major and teres minor, being also overlapped by the latter muscle. 

 Otherwise as in man. 



Pronator radii teres. 



The coronoid head is well developed and the median nerve ran 

 between the two heads of the muscle. The insertion, which was 

 fleshy, extended lower down than in man. 



Flexor carpi radialis. 

 There was an additional origin from and fibrous septum situated
