In the two animals (Peccary and Elephant ) against 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 scapuhe 

 extends up to the atlas. We have little doubt that this is the same 

 muscle which we have already described in the Mustelidae (XXXIV.) 

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

 lates it is much more closely blended with the serratns than 

 with the rhomboid sheet. It is quite possible that we were Wrong 

 in associating it by name BO closely with the rhomboid lamina,aiiii 

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

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

 portion of the serratns ventralis sheet (serratns magiius of human 

 anatomy) is, as usual, the posterior thoracis.- The part from the 

 transverse processes ol -the cervical vertebra) is supplied- •!' rota -some 

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

 the 4th and 5th, in the Brocket Deer from the 5th ami <>th. 



The insertion is into the ventral surface of the suprascapular 

 cartilage, closel) blended with the insertion of the rhomboids, and 



also -lightly t-o thv adjoining part of the bony subscapular fossa.
