MR. J. C. GALTON ON THE MYOLOGY OF 



anterior and posterior edges of the condyloid foramen ; these diverge, however, at the 

 internal edge, so as to leave a fissure for the passage of the median vessels and nerves. 

 A similar arrangement has been already described by me as existing in Dast/pus. 

 . On the left side of the animal I found what may be regarded as an indication of the 

 " short variety" (Wood), in the shape of a thin, flat muscular slip, which communicated 

 with the posterior surface of the muscle by a delicate aponeurotically expanded tendon, 

 winch in part was inserted by a thin tendon into the lower portion of the inner tube' 

 rosity, in part communicated with the uppermost of the inserted fibres of the snbscapu- 

 laris by a thin expanded aponeurosis, which ran along immediately in front of the 

 terminal portion of the bulk of this muscle. 



This muscle has, according to Eapp, in M. tamcmdua, an insertion of considerable 



extent above the inner condyle of the humerus. It appears, also, to communicate with 



the short head of the biceps, since this author mentions the "common tendon" of these 

 two muscles 1 . 



Pouchet, in his monograph upon the Great Anteater, describes and figures the "long" 



variety only of the coraco-brachialis, which muscle is fused at origin with the short head 

 01 the bicepsK 



mceps.-A single muscle, but well developed. It arises by a strong flattened tendon, 

 irom the superior edge of the glenoid cavity of the scapula, immediately external to the 

 root of the coracoid process, being covered at its origin by the terminal portion of the
