condyle and the septum between it and that part of the flexor longus pollicis which 
arises from the same condyle. There is no median tendon; but from the deep surface 
of the muscle a small tendon is given off which joins the superficial surface of that of 
the flexor profundus (see woodcut, fig. 13,**). The main tendon of the flexor sublimis 
divides into four (of which that to the index is the largest), which are, as usual, the 
perforated tendons of the four ulnar digits.

The hook represented dragging back the flexor 
sublimis passes over its median tendon.—From 
P.Z.S. 1865, p. 245. 
In Z. varius the small long tendon, on joining the profundus, exists as in catta; but 
the four perforated tendons to the digits are nearly of equal size, represented so by 
Cuvier, ‘ Myologie,’ pl. 68. fig. 2, x. 
Delineated in Galago crassicaudatus (Pl. II. fig. 3, and Pl. IV. fig. 14, F.s.d). The 
tendinous slip from this muscle to the flexor profundus digitorum in the latter Plate is 
indicated by **. 
In G. peli Kingma' describes the four perforated tendons as splitting beneath the 
first phalanx of each digit, except that going to the fifth digit, which splits beneath the 
metacarpal. ‘This he is disposed to consider a Jusus nature; but Van Campen shows 
that the same thing exists in the Potto. 
‘In the specimens of @. allenii we observed that the tendinous union with the profundus, 
when pursued up the arm, was that which formed the superficial slip on the middle and 
in front of the belly of the muscle.
