THE MUSCLE 

 6. Transversalis Hyoidei. 



By this name Bourgelat has described a short riband of parallel muscular 

 fibres, which unites the superior extremities of the styloid cornua, and 

 approximates them to each other. 



DIFFERENTIAL CHARACTERS OF THE MUSCLES OF THE HEAD IN OTHER THAN SOLIPED 



ANIMALS. 



A. Facial Region. 

 RUMINANTS. There are found in the Ox . 



1. An orbicular muscle of the lips, analogous to that in the Horse. 



2. An alveolo-labialis of the same kind (fig. 112, 5). 



3. A zyqomaticus or zygomatico-labialis, stronger and redder than in Solipeds. 

 Its aponeurosis of origin, covered by the cuticularis muscle of the face, extends upon, 

 the surface of the masseter muscle as far back as the zvgomatic arch, to which it is 

 attached (fig. 112, 7).
