Metatheria

Metatheria is a grouping within the animal class Mammalia. First proposed by Thomas Henry Huxley in 1880, it is a slightly more inclusive group than the marsupials; it contains all of the living mammals with abdominal pouches (most female marsupials) as well as all animals more closely related to them than to placental mammals like armadillos and humans. Some female metatherians, like the shrew opossum, lack a pouch.
