![and runs from the base of the third metacarpal to the proximal phalanx of the thumb. Fig. 6. Muscles of the Little Finger.—Two muscles in most cases rise from the pisiform and run to the inner sesamoid bone on the palmar surface of the head of the metacarpal bone, and so to the base of the proximal phalanx ; both of these I regard as abductor minimi digiti. The flexor brevis minimi digiti is repre- sented by the ulnar slip of the interosseous layer of muscles going to the same place as the last. The opponens minimi digiti I have never seen. The adductor minimi digiti is sometimes present, running from the centre of the semilunar cartilage, superficial to the interossei, to the outer sesamoid bone of the little finger ; it is present in Myopotamus, Hystrix, Coelogenys, and Xerus. (See fig- ... . Adductor Indicia.—Rises by the side of the adductor minimi digiti, and is attached to the ulnar sesamoid bone of the index. In Hystrix a muscle rises from its insertion, and ruus across the metacarpal bones to the insertion of the adductor minimi digiti in a semilunar curve, with the concavity towards the tips of the fingers.
