Synopsis of Suborders. 



I. Carnivora. The grinders of three distinct forms ; the premolars 

 conical and separated from the hinder (tubercular) molars by a 

 sharp-edged flesh-tooth mth a tubercle on its inner edge. 



II. Omnivora. The grinders similar, nearly of the same form, gra- 

 dually passing into each other, only varying in size, from the 

 false to the tubercular grinders, without any distinct sharp- 

 edged flesh-tooth. 



Suborder I. CARNIVORA.

 cal and separated from the hinder (tubercular) grinders by a 

 sharp-edged flesh-tooth -with a tubercle on its inner side.

I published an arrangement of the genera of the Viverridse then 

 known, according to the characters afforded by the hairiness or bald- 

 ness of the soles of the hind feet, in the ' Proceedings of the Zoolo- 

 gical Society ' for 1832, p. 63, which is well adapted for the purpose, 

 though, like other arrangements, it is not infallible nor to be used 

 too strictly, or it will separate genera naturally allied to each other. 

 The continued study of the subject has shown me several other 

 characters which I had before overlooked. The following arrange- 

 ment seems best adapted to exhibit the natural affinities of the 

 genera as far as they can be shown in a linear series, and one that 

 wiU enable the student to determine the species. . The tribes cha- 

 racterized in the paper in the ' Proceedings of the Zoological Society ' 

 for 1832 may be divided into two groups, according to the hairiness 

 of the toes and the form of the claws, characterized by the foot of 

 the Cat, the Dog, and the Bear. 



The bones of the toes of the animals of the first group, called 

 JEluropoda, as in the Cats, form an angularly arched line, the last 

 phalange being bent up, so that the animal, when it walks, does not 

 blunt its claws, which are only exserted when it wants to catch or 

 tear some other animal.
