1894. J MAMMALIAN HAND AND FOOT. 369 



(Nerv. plantaris inedialis supplies the four toes 1-4 and the 

 inner half of fifth, but there is an anastomosis between the lateral 

 branch of the nerve and the medial.) 



The tendons of the flexor digitorum sublimis (tibialis) are weak ; 

 they are perforated by the tendons of the profundus. The sublimis 

 goes to the 5th, 4th, 3rd, and 2nd toes ; it ends on the I. phalanx 

 and on the tendon-sheath of the profundus, especially on the ligg. 

 annularia. 



The flexor digit, profundus (flbularis) gives five tendons to 

 toes 1-5, the tendons for the 2nd and 3rd toes being more connected 

 than the others. 



I have found only two lumbricales, to the 4th and 5th toes ; they 

 are very strong. 



The adductore-s (plantar layer, Cunningham) go to the hallux, 

 2nd and 5th toes. 



The abductor dig. minimi arises from the calcaneum and ends on 

 phalanx I. of the 5th toe. 



The tendon of the tibialis posticus is cleft, both parts ending on 

 the naviculare. 



ft. Extensores. 



The tibialis anticus is inserted into the internal cuneiform, the 

 tendon being a little divided. 



The peronceus longus is very strong ; it crosses almost trans- 

 versely on the planta and ends on the first metatarsal bone. 



b. EDENTATA. 



1. EuPHBACTUS MHST7TUS. 



a. Flexor es. 



The plantaris (?) arises from the femur (lower end) and the 

 fibula (upper end), or the knee-joint ; it ends in the fascia plant, 

 superfic. and tendons which go to the Ph. and the " five toes," 

 ending there in the tendon-sheaths. 



No flexor brevis superficialis is present. 



The flexores longi (subl. and prof.) are connected with each other 

 but divisible ; they form one large tendon which divides into 

 separate tendons. Each tendon is cleft, but there is no 

 perforation. 



A muscle arises from the fibula and is inserted into : — (1) the 

 proc. transversus calcanei ; (2) the tendon-sheath of the peronaeus 

 brevis and minimi ; fascia dorsalis ; (3) the ligam. transversum 

 on the ankle-joint. 



/3. Extensores. 



The extensor digitorum et hallucis longus goes to all five toes, the 

 fourth toe getting two tendons. 



There is an extensor hallucis " proprius" (like the ext. poll, 

 longus) arising from theflbida and inserted into the first phalanx 

 of the great toe together with the extensor brevis.
