modern Felidse than it does any other bone. These considerations 

 justify the classification of the Monte Hermoso femur, at least provi- 

 sionally, with this family. 



In order to complete the study and comparisons of the Monte 

 Hermoso specimen, the writer took a series of measurements, which 

 are presented in the tables that follow. The figures only confirm and 

 accentuate the visually noted differences between the Tetraprothomo 

 femur and the femora of the Primates and its affihations with the 

 Carnivora, more especially the cats. The table of indexes is particu- 

 larly worth perusal, for it shows in concentrated form the enormous 

 differences between the bone under consideration and the corre- 

 sponding bone of the Primate, and its close approximation to the 

 corresponding bone in cats, in such important features as the relative 

 proportions of the lower part of the diaphysis and tliose of the entire 

 lower extremity.
