1901.J THE MUSCLES OF TJIE UNGULATA, 093 



it is present it is usually merely a fibrous band stretching from 

 the internal condyle to the middle of the shaft of the radius on 

 its anterior surface. 



In the Hippopotamus (1. 3) it is absent. 



In the Suidae it may be present as a small fleshy muscle (5, 6, 

 7. 14) or absent (11, 1*2). 



In the Camelidae (18) it is rudimentary. 



[n the Tragulidse (20, 21 ) it is small but fleshy. 



In the Cervidae (25. 26, 27. 28) absent. 



In the BoyidaB it is absent according to Chauveau (II.) and 

 Bronn (VL), feeble according to Lesbres ( \'.). We (bund it as a 

 fibrous band in the Ox (36), Sheep (45), and Antelope ( 10) ; and 

 Meckel (VII.) says it is rudimentary in the ({oat. 



In the Tapiriche a feeble muscle was present in 50, 52a, and 

 •5.3. but not in 52 or 54. 



In the Equidte, Chauveau (II.) and Bronn (VI.) say that it is 

 absent; but Lesbres (V.) describes an occasional fibrous rudi- 

 mentary band. 



In the Rhinoceros (63) it is absent. 



In the Hvrax (67. 68) it is present but rudimentary (see text- 

 fig. 91). 



In the Elephant (72, 74, 77. 78, 70) there is always a strong- 

 fibrous band running from the internal condyle to the middle of 

 the radius, but this is usually reinforced by some fleshy fibres. 

 Cm ier says that this fleshy part is only found close to the flexor 

 carpi radialis ; but Anderson (XXVII.) and Paterson and Dun 

 (70) describe it as lying deep to the fibrous band, and having an 

 attachment to the radius about 5 in. long. The specimen of the 

 African Elephant in the Koy. Coll. Surg. Museum (78) agrees 

 with Anderson's description. From the foregoing it will be seen 

 that the muscle is best marked in the Suidre and Tragulidse, and 

 least well-marked in the Cervidae and Perissodacfyla. In the Pig 

 it is supplied b} r the median nerve. 



Flexor carpi radialis. — This is the radialis interims of many of 

 the veterinary authors; it rises from the internal condyle, and, 

 after a short, fusiform, fleshy belly, ends in a long tendon which 

 runs in a fibrous canal in the lower half of the radius. The 

 insertion is into the palmar surface of the base of the metacarpal 

 bone of the index or medius, or both, according to their develop- 

 ment. In the Elephaut the fleshy belly of the muscle is very 

 remarkable; between the fleshy bundles are a number of longitu- 

 dinal planes of yellow elastic tissue, which in a transverse seel ion 

 have a coarse network appearance. There is a good specimen of 

 this in the Roy. Coll. Surg. Museum. The nerve-supply in the

Pabnarit tongue* — Although this muscle is often described in 

 the scattered literature of the subject, we believe thai it is onb 

 presenl in the Subnngulata, i.e. in the Procaviida and EHephan- 

 tidae, The confusion as a ride is due fco mistaking the extensor
