THE ANATOMY OF THE INDIAN ELEPHANT. 41 



Not in C. and L. 



The Intercostal muscles present the usual arrangement, but 

 are continued unusually far downwards between the costal 

 cartilages. 



SUPEKFICIAL CeKVICAL MuSCLES. 



Sterno-maxillaris arises from the first rib, adjacent to the 

 sternum. It forms a strap-like band of nearly uniform breadth 

 (about two inches), but expands greatly, and becomes aponeurotic 

 at its insertion into the lower jaw, at and in front of the angle. 



C. and L.— 274-5 (x); 276-7 {x') ; 287-8 (+&) ; 292-3 



(+ &^). 



Sterno-mastoideus. — A muscle which may be held to correspond 

 with this, though it has no attachment either to the sternum or 

 the mastoid, springs from the first rib, several inches above 

 sterno-maxillaris (i.e., nearer the vertebral column). It passes 

 obliquely forwards and outwards, contracting to a thin tendon, 

 which finally expands upon the root of the zygoma. 



C. and L.— 274-5 (6); 276-7 (&); 287-8 (&); 290-1 (b) ; 

 292-3 (&). 



Muscles of the Back. 



Trapezius arises from the ligamentum nuchse and vertebral 

 aponeurosis between the third and fourteenth dorsal vertebrae. 

 It is inserted into the posterior surface of the spine of the 

 scapula and the superior border of the unciform process. 



C. and L.— 274-5 (a, a^) ; 276-7 {a^, a^) ; 287-8 (a, a\ a^). 

 An occipital origin is ascribed to this muscle in the Plates. 



Latissimus dorsi arises from the vertebral aponeurosis and the 

 ribs from the ninth to the fourteenth. The fibres become twisted, 

 and converge to a tendon which is inserted into the neck of the 

 humerus. The tendon of insertion is divided; the superficial 

 portion is inserted above teres major, the deeper and smaller part 

 behind it, 



C. and L.— 274-5 ({) ; 276-7 (^); 283, figs. 1, 2 (i) ■ 287-8 (i). 

 Eepresented as arising from the sixth to the twelfth ribs. 



Bhomboideus major arises from the ligamentum nuchse be- 

 tween the fourth and six dorsal vertebrae, and is inserted into 

 the postero-superior border of the scapula.
