* I regard the division of the Marsupialia as equivalent to the monodelphous \ 

 Mammalia, for not only are there found in it representatives of most of the orders of j 

 Monodelphia, but, further, there are in the Monodelphia many indications which point I 

 to their having arisen from a didelphous form. The Marsupialia,. or uniting with them 

 the Monotremata, the Implacentalia, consequently represent the ancestors of the , 

 Placentalia. 



t The great variations which the relations of the placenta present in various 

 Edentata weaken somewhat the value of the placental classification, although the 

 various orders are generally distinguished by the similar characters of their placenta. 



J The Prosimii form a stem-group, in some divisions of which peculiarities are I 

 retained which are found in various other of the following orders. Thus there are ! 

 characters which we meet with in Insectivora, Rodentia, Oarnivora, and Primates. , 



§ and II The Proboscidea and Lamnungia are representatives of orders which itis 

 very difficult to associate with the rest. They have genetic affinities to the Rodentia; 

 ITyrax has also relations to the TJngulata.
