The por-tion of the sujjerficial layer of theamphibian palmar aponeurosis,,which covers the flexor brevis super-ficialis, has disappeared in the reptilia or is represented in theflexor, if one prefers to state it that way. The more proximal por-tions of the aponeurosis, however, are represented by the volar cartilage,and the strong tendons which are continued distally toward the fingersfrom the volar cartilage are, in their proximal portions, the representa-tives of the tendoR5 formed from the deep layer of the amphibianaponeurosis. Beyond the point of the bifurcation of the slips of theflexor superflcialis these tendons in the amphibia fuse with tlie tendons. Fio. 12.
