THE HYOID BONES. 37 
consists of a curved bone between 
these two points. 
c. The anterior cornu. 
Each consists of four parts, and connects 
the series with the cranium. 
i. The tympanohyal lies in a canal on the 
inner side of the stylomastoid foramen 
between the tympanic and _periotic 
bone. Its ossified portion is cylind- 
rical and is connected with the proxi- 
mal end of the stylohyal by a band 
of cartilage.’ 
ii. The stylohyal is a curved, somewhat 
twisted bone, forming the posterior 
portion of the anterior cornu, of which 
it is the largest division. 
ii. The epihyal is slightly shorter than the 
stylohyal, and dilated at its distal and 
proximal ends. 
iv. The ceratohyal is a short stout bone, 
attached at its distal end to the 
basihyal. 
? As has been pointed out by Prof. Flower, ‘‘it can be seen more 
distinctly in some dogs’ skuils than others.”
