example, the larynx of the Jaguar with that of the present animal, 

 both natives of the wilds of the American continent. In the Jaguar 

 we find a larynx indicating from its general magnitude considerable 

 depth in the intonations of the voice, whereas in the Puma, if we 

 take either its diameter, or its distance from the termination of the 

 palate and base of the tongue, we are led to expect neither the 

 roar of the Lion nor the growl of the Jag uar, but the shrill tones of 

 an animal, ferocious indeed, but of all others of the genus perhaps 

 the most stealthy and insidious. I am the more inclined to call at- 

 tention to these differences, because I think that I have observed a 

 kind of mutual correspondence between the voice and the habits 

 of animals, a point well worthy minute investigation, and on which, 

 on a future occasion, I design to offer a few observations.

Mr. Gray, in directing the attention of the Meeting to them, 

 remarked on them as constituting the type of a new genus, for 

 which he proposed, on account of the shortness of the nose-leaf, the 

 name of 



Brachyphylla.

"•The cutting teeth are four in each jaw, of which the two upper 

 central are large, conical and close together; the side ones very 

 small, low and rudimentary ; and the lower ones small, equal and 

 closely pressed between the canines. The canines are large, the lower 

 ones titting before the upper ; the upper ones very large, with a 

 deep notch on the hinder side. The grinders are five on each side 

 of either jaw, of which three are truea:id two false: the two lower 

 false grinders on each side are equal ; the front ones of the upper 

 jatv are very small and rudimentary. 



" The head is ovate: the face short and blunt: the end of the 

 nose truncated, with a short broad flat nose-leaf, connected with 

 the lips in front, and surrounded by a deep groove behind, separa- 

 ting it from the rest of the face ; the groove is edged behind by a 

 rounded callous ridge. The nostrils are ovate, rather large, open, 

 and placed widely apart from each other, one being situated on each 

 side of the middle of the nose-leaf. The lips are smooth, without 

 any beard on the inner side of the angle of the mouth: the upper
