*This should be compared with the previous subspecies. Difference of 

 sex might be responsible for different body and cranial dimensions. The color- 

 ing of the two individuals is apparently similar, merely a gray phase of F. 

 jaguarondi. 



fShould be compared with F. ;'. cacomitli and F. j. iolteca. Apparently 

 an individual slight variation in color so common in examples of F. jaguarondi.
