(olecranal). and (4) radial origins. In the Horse (50, 58) there 

 are condylar, radial, and olecranal heads, and the insertion of 

 course is only into the medius. 



The Khinoceros (63) apparently lias two condylar heads, one of 

 which Beddard aud Treves call paluiaris longus. The insertion is 

 into all three digits. 



In the Hyrax (68) we found one condylar head rising in common 

 with the flexor subliinis and probably corresponding to the con- 

 dylo-radialis, there were also radial and ulnar heads. The inser- 

 tion (07, 08) is into all four digits. 



In the Elephant (77, 78) there are radio-condylar, radial, and 

 ulnar heads and the insertion is into all five digits (74). Ander- 

 son (XXVII.) describes a radio-carpeus rising from the anterior 

 surface of the radius, external to the attachment of the pronator 

 radii teres, and corresponding to the origin of the flexor longus 

 pollicis in Man ; it is inserted into the anterior annular ligament 

 and is apparently also present as the muscle marked £ in Cuvier 

 and Laurillard's plate (I.). 



We are able to give the following details of the nerve-supply. 

 In the Pig (11) and Peccary (14) the condylo-radialis, condylo- 

 centralis, and radialis slips are supplied entirely by the median, 

 the ulnaris entirely by the ulnar, while the condylo-ulnaris gets a 

 twig from both the median and ulnar. 



In the Brocket (27) the condylo-radialis and radialis are sup- 

 plied by the median, the ulnaris by the ulnar, and the condylo- 

 ulnaris by the median and ulnar. 



In the Duiker-bok (49) the condylo -radial and condylo-central 

 heads were supplied by the median, the ulnaris by the ulnar, 

 while the condylo-ulnar was entirely supplied by the ulnar. 



Lumhrlcahs. — In the Hippopotamus (1) there was only one 

 lumbrical rising from the anuularis tendon. Iu the Suidae (4, 6, 

 11) one from the index teudon of the flexor profundus. In the 

 Tragulidte. lvinberg's Chevrotain (20) had one evidently belonging 

 to the annularis, but in C'hatiu's AYater-Chevrotain (XI.) the index 

 one was apparently alone present. In the Cervidac (25, 26, 27. 28.) 

 and the Bovidic ('So, 35, 30, 37, 38, 40, 43, 49) no lumbricals are 

 present. In the Tapiridae (51. ~)~>) there me three, for the index, 

 medius, and annularis. In the Equidas (50, 57. 58) two, one from 

 each side of the single profundus tendon, corresponding therefore 

 to medius and annularis. 



Iu the Khinoceros there are none according to Beddard and 

 Treves (XX. ). 



Iu the Hyrax (07. 68 ) the medius and annularis are present, 

 but Meckel failed to find any in his specimen (71 ) (see OwA-lig. 91). 



In the Elephant (74) there were four, but in (73.) and (7b) the 

 ulnar one was wanting. 



Pronator quadratus. The onl) ungulate in which we have 

 been able to find any notice of this muscle i^ the Tapir (55), in 

 which Murie says that it occupies the lower quarter of the 

 forearm.
