With one exception the following ungulates are from the 
Val d'Arno horizon, Olivola, Province of Massa, Italy. This 
horizon is Upper Pliocene, and consists of sands and "sansino" 
(conglomerate), which, according to Dr. C. J. Forsyth-Major;? 
contain, as so far discovered, no less than forty species of 
mammals. The locality is in a lateral valley. All the limb 
bones and the greater part of the various dentitions are in an 
excellent state of preservation.
