An interesting similarity with reference to the distribution of the tendons exists in Cheiromysexcept that there is no tendon given off to the hallux. Flexor tendons of the foot. F. 1. d.

It arises by two heads—one from the posterior sur- face of the fibula, the other, a very small fasciculus, from the tendon of the popliteus (fig. 5). Its strong tendon gives off a slip to the hallux, joining that going to the same digit from the flexor longus. It then bifurcates, one part joining that branch of the flexor longus which goes to the index and middle digits, and forms its share of each of their tendons; the other joins a tendon of the flexor longus, and forms with it the perforating tendon of the fourth digit (fig. 6, F. 1. h). A very similar arrangement exists in Cheiromys2; only this muscle exclusively furnishes the hallux-tendon. The flexor brevis diyitorum is very narrow ; it arises from the plantar surface of the tendon of the flexor longus, and ends in two 1 Owen, loc. cit. p. 67, pi. 25. fig. 2. no. 32. 2 Ibid. no. 31.
