  • proper n. A taxonomic infraclass within the subclass Theria — the animals more closely related to placentals like rodents and humans than to marsupials.

from The Century Dictionary and Cyclopedia

  • In zoology: A term proposed by Gill in 1872 for one of the major groups of the Mammalia, including the Mouodelphia and the Didelphia, as together contrasted with Prototheria.
  • Restricted later by Huxley to the Monodelphia, the Didelphia being called Metatheria: in this sense, an exact synonym of Monodelphia and Placentalia.

Etymologies

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Ancient Greek εὖ (eu, "good, true") + θηρίον (thērion, "beast").

Examples

  • Mammalia consists of and contains Eutheria, Marsupialia, etc.

    A Disclaimer for Behe?

  • Monotremes are sometimes called Prototheria, in contrast with Metatheria (marsupials) and Eutheria (placental mammals).

    Monotremata

  • Eutheria, in that it prevents injury to the skull at birth; but how explain on teleological principles the similar ossification from separate centres in marsupials, birds and reptiles?

    Form and Function A Contribution to the History of Animal Morphology

  • Eutheria, or higher animals, which include all the common animals from the mole or rabbit up to man.

    Thomas Henry Huxley; A Sketch Of His Life And Work

  • To him are due not only the names, but the idea, that the mammalian animals fall into three grades of ascending complexity of organisation: the reptile-like Prototheria, which lay large eggs, and which have many other reptilian characters; the Metatheria, or marsupial animals; the Eutheria, or higher animals, which include all the common animals from the mole or rabbit up to man.

    Thomas Henry Huxley A Sketch Of His Life And Work

  • In the higher Mammals (Eutheria) the corpora lutea show a special relation in their development to the occurrence of pregnancy, that is to say, they have a different history when ovulation is followed by pregnancy to that which they have when the ova, from the escape of which they arise, are not fertilised.

    Hormones and Heredity

  • In this way it seems to me we have a logical explanation of the fact that the corpora lutea in the Marsupial are not absorbed at parturition as in Eutheria.

    Hormones and Heredity

  • The scrotum is always anterior to the origin of the penis, although in the Eutheria apparently behind that organ.
