Thus the upper jaw is both short and narrow ; and the slenderness 

 of the rami of the mandible is not less remarkable, though in this 

 respect C. cancrivorus and C. proctjonoides approach Otocyon.

On inspection of the foregoing tables of the actual and the pro- 

 portional measurements of the skulls and teeth, the wide differences 

 between Otocyon and all the other Canidse become apparent. 



Confining our attention for the present to those teeth in Otocyon 

 which answer to those met with in other Canidse, it is obvious that the 

 sectorial teeth are much smaller in proportion to the basieranial 

 axis, that the difference between ^-y and ~-^, ^^^ and ;;^, is much 

 less, and that ^-^^^ is never greatly longer and may be shorter than 



m. 1
