The =larynx= is more compact than in the horse, and presents numerous
differential features. The =cricoid cartilage= is compressed laterally.
The lamina is not distinctly marked off from the arch; it slopes
downward and backward and has a large median ridge. The =thyroid
cartilage= is complete ventrally, _i. e._, the laminæ are united
throughout to form a long plate which is notched in front and behind;
the laryngeal prominence is small and is situated posteriorly. The
height and thickness of the cartilage increase from before backward. The
posterior cornua are about an inch long, and form syndesmoses with the
cricoid cartilage; the short anterior cornua unite similarly with the
hyoid bone. The =epiglottis= is oval in outline and its apex is rounded;
its base rests on the thyro-hyoid membrane, to which it is rather
loosely attached. The cuneiform cartilages are absent. The =arytenoid
cartilages= present only slight differences. The muscular process is
well developed, and the vocal process is narrow and long. The =vocal
cords= 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
ventricles= are extremely shallow, and the saccules are absent. The
thyro-arytenoideus muscle is not divided; it is fan-shaped, thick, and
narrow dorsally; ventrally, it is attached to the base of the
epiglottis, the angle of the union of the thyroid laminæ, and the
crico-thyroid membrane. The hyo-epiglotticus muscle is large and bifid.
