94 NATURAL HISTORY OF KERGUELEN ISLAND. 



Beltoideus, arisiug from coracoid end of scapula, filliug the space 

 between tbe tendou of pectoralis medius and latissimius dorsi, to be 

 inserted into the pectoral ridge of humerus. 



Biceps presents nothing unusual. 



Infraspinutus and teres major* are represented by a single muscle, 

 which arises from the entire dorsal margin of scapula, and is inserted 

 into the ulnar tuberosity of humerus. 



A stout fasciculus of soft, daik muscle, which arises from nearly the 

 whole of the internal surface of coracoid and of the adjoining stout 

 strip of membrane, passes outward and upward through humero- 

 coracoid space to be inserted into the anterior tuberosity of the 

 humerus. Perhaps this is the muscle described by Owent as the 

 analogue of coraco-brachialis, and said by him to "attain its greatest 

 relative size in the Rasores, where it arises from almost the whole of 

 the coracoideum." 



Triceps extensor ciihiti is divided into two distinct muscles, as usual. 



Numerous isolated fibres, represen ting j>/o^2/^wia myoides, oi iginate from 

 anterior half of clavicle and i)roceed upward between the layers of the 

 superficial fascia, to be inserted into the skin, suijerficial surface of 

 oesophagus, and crop. 



MUSCLES OF THE LOWER EXTREMITY. 



iSartoritis as usual. 



Rectus femoris and tensor vagincc femoris {abductor magmis of Owen) 

 arise thin and fan-shaped, by a membranous aponeurosis from the 

 superficial fascia of the back and from outer margin of sacrum and 

 ischium, to be inserted by tro tendons, the uppermost going to the 

 anterior part of the sheath of cruraeus, the lowermost to the head of 

 fibula.. The muscle is very thin and its tendon a delicate aponeu- 

 rosis, 



Gliitm and crurccus (including internal and external msti) present 

 no characters of particular interest. 



Biceps arises just above inner hamstring muscle from ischium, and is 

 inserted into fibula, fully 0.8 inch below the kueejoint. 



Seminiembranosus and semitendinosus are inserted into tibia at about 

 the same level, above insertion of biceps. 



Adductores and gastrocnemius not noted as peculiar.
