    weak and slender. It arises by the usual two heads, the inner one being very much higher than the outer one. It has the ordinary insertion by the tendo Achillis, which is moderately developed, the gastrocnemius being muscular almost its entire length (fig. 5, G). The soleus appears to be represented by a flat rhomboidal band of muscular fibre without any tendon. It arises from the posterior margin of the head of the fibula and the inner border of the flexor longus hallucis for about half its length, then joins the outer border of the gastrocnemius for above half an inch (fig. 5, S). In Loris, according to Meckel1, it arises from almost the whole of the fibula. We were uuable to find any trace of a plantaris muscle. Fig. 5. Hind limb between knee and ankle. P. Popliteus. G.

It arises from the pos- terior surface of the tibia as far inwards as the internal lateral liga- ment (fig. 5, P). It is inserted by a very strong tendon (contain- ing a large sesamoid bone), which passes behind, rather than beneath, the external lateral ligament, into the depression outside the outer condyle. In Tarsius, according to Burmeister2, this muscle is in- 1 Anat. Comp. vol. vi. p. 421. - Op. cit. p. 75, t. 4. fig. 5. no. 23. [13]
