*This should be compared with the previous subspecies. Difference of 
sex might be responsible for different body and cranial dimensions. The color-

jaguarondt. 
Should be compared with F. j. cacomiili and F. 7. tolieca. _ Apparently 
an individual slight variation in color so common in examples of F. jaguarond1.
