In- tlie -two animals (Peccary and Elephant) agaiust which au 

 asterisk is placed there was a perfectly distinct. slip from the 

 transverse process of the atlas, and in a great many others it will 

 be seen that the serratus ventralis colli or levator anguli scapuhi^ 

 extends up to the atlas. ^V^e have little doubt that this is the same 

 muscle \^hich we have already described in the Mustelidae (XXSI V.) 

 under the name of rhomboideus profundus, though in the Ungu- 

 lates it is much more closely blended with the serratus than 

 with the rhomboid sheet. It is quite possible tha^t we were wrong 

 in- associating it by name so closely with the rhomboid lamina, ana 

 tliat it should be looked upon more as a connecting-link between 

 the rhomboid and serratus sheets. The nerve-supply of the costal 

 portion of the serratus ventralis sheet-(serratu<5 magnus-of human 

 anatomy) is, fts usual, the posterior thoracic.- The jjart from the 

 transverse processes of -the cervical vortebrte- is supplied-fromsome 

 of the-cervical-nerves— in the -Pig, -Peccary, -and Duiker-bok from 

 the 4th and 5th, in the Brocket Deer from the 5th and 6th. 



The insertion is into the ventral surface of the suprascapular 

 cartilage, closely blended with the insertion of the rhomboids, and 

 also slightly to the adjoini-ng part of the bony subscapular fossa.
