Prototheria is the subclass containing the egg-laying mammals (the echidna and platypus). Metatheria is the subclass that encompasses marsupials and a few other now-extinct mammals that were not placental. The other subclass of mammals is Eutheria, which contains all placental mammals, which make up the majority of mammals.
