composing the superficial or condyloid liead are continued uninterrup- 

 tedly along the internal lateral ligament to the inner margin of the 

 coronoid process, which they occupy along nearly its whole length, and 

 are frequently connected there with the coronoid tendon of the prona- 

 tor radii teres. This part usually gives rise to the indicial tendon of 

 the muscle. In the subject above mentioned it constituted a separate 

 muscle. In addition to this, the most common coronoid attachment, 

 however, there sometimes exists a strong flat tendon arising from the 

 oitter and loiver border of the coronoid process and joining, not the 

 condyloid, but the radial origin of the muscle. 



In the sketches of the muscular anatomy of the limbs of an adult 

 female Orang-utan dissected by the author, he finds that in this animal 

 this flat coronoid tendon gives attachment not only to some of the fibres 

 of the radial origin of the sublimis, but also to the Jlexor carpi radialis, 

 which arises both from it and from the oblique line and outer border of 

 the radius by a common aponeurosis with the sublimis. This arrange- 

 ment has been observed by INIr. Macalister in the human arm (op. cif. 

 p. 12). In the Orang, the four tendons of the flexor sublimis are 

 attached to separate muscles, the areolar intervals between which are 

 very readily separable. That to the index lies deepest, and arises fix)m 

 the upper coronoid origin and lateral ligament. Those to the second and 

 third fingers both arise from the oblique line and border of the radius, 

 the latter being superficial and attached also to the condyle of the hume- 

 rus, while the former is connected chiefly Avith the lower coronoid ten- 

 don, but having a separate slip also from the internal lateral ligament ; 

 while the muscle to the little finger arises superficially from the condyle 

 of the humerus. 



In one of the above-mentioned varieties of the flexor sublimis (jSTo, 8) 

 was a separate fusiform muscle to the little finger, arising from a tendi- 

 nous intersection springing from the condyle of the humerus. In 

 another (No. 21) the tendons of the left index and little fingers both 

 were ^connected with a digastric muscle with a tendinous intersection 

 in the middle, arising from the condyle, internal lateral ligament and 

 upper coronoid origin. This has been observed by Macalister in a fe- 

 male subject, with many other irregularities. Such a digastric portion 

 has been recorded also by Meckel (Muskellehre, S. 536). The same 

 author describes a similar intersection in the Loris (Anat. Comp. 6. 

 p. 34iO). In JSTo. 31 all the tendons were provided with separate mus- 

 cles, the first arising with a digastric formation from the condyle, inter- 

 nal lateral ligament and coronoid process ; the second from the radius 

 and loAver coronoid tendon ; the third from the condyle and internal 

 lateral ligament ; and the fourth from the condyle only. In No. 10 

 was a tendinous slip from the superficial surface of the sublimis to the 

 annular ligament, the palmaris longus being normal.
