CARNIVORA. Ursus Malayanus. Larynx : 

 H. 1'55. Thyroid: wings unite at an obtuse 

 angle; tubercle in mesial plane a (fig- 900), to 

 which the epiglottis is attached ; margins, 

 superior ascending upwards, inferior ex- 

 cavated in front as far as the tubercles b 

 (Jig. 900). Cornua : superior short ; inferior 

 very long. Cricoid : superior margin inclined 

 upwards, with a notch in front, by which the 

 body is nearly cut through ; inferior con- 

 cave in front ; lateral parietes held together 

 by a transverse ligament. Arytenoids rhom- 

 boidal, between which are the sesamoids, dd, 

 furnished with small muscles to approximate 

 them. Cart. Cuneiform and C. Santorini pre- 

 sent. || Epiglottis broad ; apex obtuse. Vo- 

 cal ligaments : inferior inclined upwards to 

 the place of the superior, separated by a 

 transverse groove. L. 0'833, or nearly equal 

 those of man. 



Ursus Arctos. See WolflT.

Vivcrra Nasua. Thyroid : wings united 

 at an obtuse angle. Cricoid semitransparent. 



* Vicq. d'Azyr states that the vocal ligaments 

 are absent, but this is denied by Brandt. 



f He is also in error in stating that the epiglottis 

 is absent in the common bat. 



J Brandt thinks that the interarticular cart, cf 

 Mammalia is represented by the Cricoid of Birds ; 

 but, as Henle observes, there seems to be little 

 foundation for this opinion.
