process is well developed, and the vocal process is narrow and long. The vocal 
cords are short and project very little from the wall, so that the rima glottidis is 
wide; the vocal ligament is attached ventrally to the crico-thyroid membrane, it 
has the form of a half tube, open behind. The lateral ventricle is represented by a 
very shallow depression, and the saccule is absent. The thyro-arytenoideus muscle

is equivalent to the vocalis and ventricularis of the horse; it is fan-shaped, thick, 
and narrow dorsally; it is attached ventrally to the base of the epiglottis, the angle 
of the union of the thyroid lamin, and the crico-thyroid membrane. The hyo- 
epiglotticus muscle is large and bifid; it arises from the small cornua and at their 
articulation with the body of the hyoid bone, and thus may take the place of the 
hyoideus transversus in its action on the small cornua.
