COMPARA.TIVE ANATOMY OF THE LARYNX. 631 



ventricle according to Wolff.* In the Cat {Felis catus) the 

 larynx is small, and guarded by a long upper and pointed epi- 

 glottis. Anteriorly, the false cords are widely separated ; they 

 are in structure very fine, instead of being thick as in the Lion , 

 the true cords touch at their anterior extremities. There are 

 no cartilages of SantorinLf 



In the Tiger the arytenoids are much raised. 



In the Hysenat {Hycena striata) the superior ligaments are 

 scarcely visible, and there is but a faintly-marked ventricle. 



Plantigrada. — In the Bear§ both pairs of cords are so arranged 

 as to raise themselves nearly to the same level by their free 

 edges, and to direct towards the epiglottis the slit which forms 

 the entrance to the ventricles. 



Cuvierll says : — The posterior ligaments or true cords, which 

 are thick but very distinct, and which are attached to the 

 arytenoids, rise between the two anterior ligaments, which are 

 attached to the cuneiforms in such a manner that the four liga- 

 ments are upon the same level, and that the ventricles of the 

 glottis are simply two deep slits, open no longer towards the 

 -laryngeal cavity but facing the epiglottis. They bend inwards 

 very little between the epiglottis and the thyroid. The liga- 

 ments — or rather the external anterior — are little separated 

 from the epiglottis. 



WolffH also adopts the terms external and internal for the 

 ligaments of the larynx as being topographically correct. He 

 mentions that, whilst the external are inserted into the cunei- 

 form cartilages, the internal are attached to the arytenoids. All 

 four are inserted into the root of the epiglottis. (His examina- 

 tion was made upon a specimen of Urs%is arctos). 



The ventricle of the Ursus meles he found large and very deep. 



The Erinaceus Europceus** has only small superior cords, 

 though the ventricles are deep and sacculated.
