and to some of the South American Monkeys. Two families are 
known, the Lemuravide, from Lemuravus, the principal genus 
which has 44 teeth, and the Limnotheridw, which have not more 
than 40. The latter group is rich in genera and species. Among

he discoveries made by the same expeditions in the Miocene 
and Pliocene lake-basins of the Rocky Mountains and Pacific coast 
were likewise very numerous, and many new forms of animal life” 
were brought to light. One group of mammals found in the early 
Miocene of Oregon is allied to the modern Rhinoceros, but dif

The genus was called Diceratherium, and one of its species is the 
oldest known member of the Rhinoceros family, if not its progeD- 
itor. The most remarkable mammals found in the Miocene were
