HISTORY OF THE fASTRAPOTHEEIA 515 



dylarthra were spread over all the continents, except Australia, 

 and that from them the other ungulate orders arose in dif- 

 ferent regions. At all events, the fCondylarthra show how 

 the transition from clawed to hoofed types may have occurred 

 and perhaps actually did so, but it would be prematiu-e to 

 afl&rm this.
