the former especially in the Gibbon. The same subject, a muscular male, 

 showed also a high and large origin of the pronator radii teres in common 

 with the brachialis anticus. 



10. Chondro-coracoid muscle, passing from the latissimus dorsi at tenth 

 rib to the tip of the coracoid process. Not before recorded. The same 

 subject showed also a low origin of the pectoralis minor. 



1 1 . Biceps with four heads. — Of the two additional heads, the inner arises 

 with the brachiahs anticus, and the outer with the supinator longus. In 

 the same arm is a slip from the coraco-brachialis to the internal inter- 

 muscular septum, passing down to the condyle, and perforated by the 

 brachial artery. 



12. Coraco-capsularis. — A muscular slip from the tip of the coracoid 

 process to the capsular ligament of the shoulder-joint, inserted between 

 subscapular and triceps muscles. 



13. Brachio-fascialis, passing from the brachialis anticus to the fascia 

 over the flexor muscles of the forearm, coexistent with the semilunar fascia 

 from the biceps. 



14. Palmaris longus, with inverted belly and double origin, the addi- 

 tional one (tendinous) from the oblique line of the radius above the flexor 

 sublimis. Given off from it also is the fiexor brevis minimi digiti. A 

 precisely similar arrangement of this very uncertain muscle not before re- 

 corded. A somewhat similar arrangement found in the Gebus and Magot. 



15. Three distinct muscles and tendons connecting, — 1, the flexor 

 poinds longus with the indicial tendon of the flexor profundus digitorum ; 

 2, the flexor sublimis (coronoid origin) with the flexor pollicis longus ; 

 and 3, the flexor sublimis with the flexor profundus (middle part). 

 Segregation also of the indicial portion of the flexor profundus. 



16. Flexor brevis minimi digiti. Additional long, broad, fleshy origin 

 from the fascia of the forearm, and another from the tendon of flexor carpi 

 ulnaris. Aponeurotic slip given oif to transverse metacarpal ligament. 



1 7. Striking abnormality seen in two male subjects on both sides. A 

 long tendon with bulky, muscular belly above, arising from the outer con- 

 dyloid ridge of humerus with the extensor carpi radialis longior, and 

 inserted in one case into the base of the first metacarpal bone and origin 

 of the abductor pollicis, and in the other passing entirely into the latter 

 muscle. Not before recorded. 



18. Extensor primi internodii pollicis et indicis. — ilrising by a distinct 

 belly above the indicator, going along with that muscle, and giving off two 

 tendons, one to be implanted outside the indicator tendon, and the other 

 to supply the place of the extensor primi inteimodii pollicis. Not before 

 recorded in the human subject. Found in the Dog. 



19. Extensor proprius digiti medii. — A distinct extensor of the first 

 phalanx of the middle finger, arising from the ulna below the indicator. 



20. Extensor minimi digiti with double tendon, one going to the fourth 

 finger. Associated with this are three curious slips or displacements of
