    muscle were connected with a distinct tendon, rather smaller than the normal one, which, passing in the groove and sheath of the peroneus longus, was implanted upon the outer margin of the cuboid bone behind its peroneal groove. A similar instance has been recorded by Macalister. It is of the same character as the peroneus quartus of Otto, which was inserted into the calcaneum. The peroneus quartus has been found twice in 70 subjects by the author. Meckel describes it in the Kangaroo. In 1 male and 1 female the tendon of the brevis was found, in both legs, to give off a slip of reinforcement to that of the iertius. 50. Peroneus quinti.—This variety, constituted usually, in the human subject, by a sUp of tendon from that of the peroneus brevis, given off below the outer anltle and joining the extensor aponeurosis of the little toe, was found in the male (No. 11) to have developed upon it a complete, distinct, and fusiform muscular belly (fig. 10 a), exactly like Fig. 10 (Subject No. 11). that described in the author's paper of 1864, and also by Hal- lett in his paper in the Edin- burgh Medical and Surgical Journal of 1848. The pe- roneus tertius (6) was present and normal, and the tendons of the extensor brevis digitorum (c) complete. In 7 males—4 in both legs, 1 in the right, and 2 in the left only—the tendon of the pe- roneus quinti was complete, reaching to the extensor apo- neurosis of the little toe. The same was the case in 4 females, 2 on both sides and 2 on the left only. In 2 males in both legs, and in 6females, of which 4 were in both legs, 1 in the right, and 1 in the left only, the tendon, after parting from the peroneus brevis in the usual way, became spread out in front and lost upon the upper horder of the fifth metatarsal bone about its middle—an incomplete arrangement, said by Mr. Davis to be found also iu the Civet Cat (Journ. of Anat. and Physiol. May 18G8, p. 217). Out of 102 subjects, in the 68 males the complete muscle has been found once, the complete tendon in 18, and the incomplete tendon m 3. makin- 24 in the males. In the 34 females the complete tendon has been found in 5, and the incomplete form in 8, making 13 in the females. 1 hJS gives about an equal average in the two sexes.
