plains, and drifting sands, rather than of the moister climatic 
conditions inferred from the older lake basin theory. 
Among the chief phylogenetic results are the addition 
of at least four kinds of Canids (Fig. 6) and the tracing 
back of the Procyonidae to the Lower Miocene Phlaocyon 
( Matthew 4 ), tending to unite this phylum more closely with 
the Canidae. The Mustelidae are now represented by Mm- 
tela and Lutra. The Viverridae and Ursidae are still wholly 
unrepresented in Arrefica although evolving contemporane- 
ously in Europe. Among the distinctively American Artio- 
dactyls the Cervidae are now recorded in the Middle Mio- 
cene ( Palaeomeryx) , a fact however still requiring confirma- 
tion. In this connection should be mentioned the discovery 
of the full characters of the genus Merycodus ( Cosoryx),
