SUB-CLASS DIDELPHIA. 



A sub-class of mammals distinguished from the j^receding by the fact 

 that the young are born in an incompletely developed condition, and 

 are protected in a pouch on the abdomen of the mother, where they are 

 retained for several months, being nourished by the milk secreted 

 by the mammae therein contained. The sub-class contains but a single 

 order, the Marsupalia. 



The n:|^rsupials vary very much in size, and are mostl}' confined to 

 Australasia. A single famil}', the Didelphidx, or opossums, inhabits 

 America, and is peculiar to our continent.
