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 tlie last. The oppouens minimi digiti 1 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 boue of the little finger ; 

 it is present in Myojpotamus, Hystrix, Ooelogenys, and Xerus. (See 



Adductor Indicis. — Eises 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 runs 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. (See fig. 8, p. 273.)
