 upon the same plan as in the Dog and the canines are long, 

 the premolars increase in size from before backward and the 

 fourth lower tooth is molariform. The sectorial fourth upper 

 premolar is also molariform in appearance showing a molar-

lar but the second is greatly reduced. The sectorial first 

 lower molar has a large trigonid and a low basin-shaped talonid 

 each showing the full complement of three cusps. The second 

 molar is reduced practically to a talonid, the protoconid and 

 paraconid being absent. 



There is great variation in the dentition of the Civets (Viver-
