It will be observed that, as regards size, the Kansas tooth is 

 much nearer to that of C. occidentalis than to any of the others. 

 The tooth differs from all of the other teeth in the width of the 

 talon. The metaconid is somewhat more strongly developed than 

 in C. occidentalis. It is possible that this tooth represents a dis- 

 tinct species, but the evidence is not sufficient to establish this. 



Undetermined Felid. 



In the collection made on Spring creek, about four miles south- 

 west of Meade Center, Kan., are found some remains of a very 

 large cat-like animal. These consist of the left second metacarpal ; 

 the proximal three-fourths of the right fifth metacarpal ; the right 

 calcaneum; the proximal two-thirds of the right fourth metatarsal; 

 a proximal phalange of probably the fourth digit of the pes; and 

 the distal half of another proximal pedal phalange. There is no 

 certain evidence that any two of the bones were found together, 

 but it seems probable that all belonged to one individual. They 

 shall here be so considered. All these parts indicate an animal 

 somewhat larger than the African lion. 



The second metacarpal, as the other bones, is compared with 

 that of a lioness captured in Africa by the Roosevelt party.
