FELIS GRACILIS. 



In the number of the toes of the hind feet, and of the teeth, as well as in the 

 form of the head and body, the Delundung resembles the genus Viverra ; but the 

 character of the claws, as well as the pecuhar structure of the teeth, and the use for 

 which they are intended in the economy of the animal, indicate, in my opinion, a 

 closer affinity to FeUs. I have therefore placed it in that genus, in a separate section, 

 which I have denominated Frionodontidce; and, for the purpose of comparison, I now 

 add IlUger's detailed description of the genera FeUs and Viverra.
