are referred questionably to Felis inexpectata (Cope, 1899, pp. 247- 

 249). The proportions of the upper carnassial are such that the tooth 

 may be from the same individual as the lower jaw." 



Cope described F. inexpectata with an upper carnassial from the 

 Port Kennedy deposit as the type. To this species he referred a lower 

 jaw fragment with Mj and part of P4, some separate upper and lower 

 teeth, foot bones, and Umb fragments. The Cumberland Cave upper 

 carnassial is slightly larger and higher crowned than the type of F.

inexpectata, but it has its protocone noticeably reduced as in that 

 species. However, the Port Kennedy lower jaw is much deeper and 

 has larger teeth than the Cumberland Cave jaw portion and the notch 

 between the paracone and protocone of the lower carnassial is deeper 

 and more open than in Mj of the latter specimen. The Port Kennedy 

 lower jaw is out of proportion with the type upper tooth, which sug- 

 gests considerable individual variation or possibly that another species 

 is represented. 



The Cumberland Cave upper carnassial is nearly equal in size to the 

 type upper carnassial of Felis longicrus Brown (1908, p. 178). The 

 principal differences to be noted include somewhat narrower propor- 

 tions, a more backward sloping parastyle, relatively shorter antero- 

 posterior length of paracone, and a more reduced and less forward 

 projecting protocone than in F. longicrus. The P4 referred by Brown 

 to F. longicrus is similar to that tooth in the Cumberland Cave man- 

 dible but is distinctly larger. Brown noted the resemblance of this 

 tooth to F. onca and to the P4 in the jaw referred by Cope to F. 

 inexpectata. 



The mandible from Cumberland Cave is distinctly pumalike in 

 character, particularly in the relative proportions of P4 and Mi. 

 Though smaller than an average size jaguar, it is apparently larger 



" The specimens were associated, according to Dr. Gidley's notes.
