International Code of Zoological Nomenclature - Structure

Structure

The Code divides names in the following manner:

  • Names above the family group
  • Family-group names
  • Genus-group names
  • Species-group names

The names above the family group are regulated only as to the requirements for publication; there is no restriction to the number of ranks and the use of names is not restricted by priority.

The names in the family, genus, and species groups are fully regulated by the provisions in the Code. There is no limitation to the number of ranks allowed in the family group. The genus group has only two ranks: genus and subgenus. The species group has only two ranks: species and subspecies.

Famous quotes containing the word structure:

    The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.
    —For the State of New Jersey, U.S. public relief program (1935-1943)

    When a house is tottering to its fall,
    The strain lies heaviest on the weakest part,
    One tiny crack throughout the structure spreads,
    And its own weight soon brings it toppling down.
    Ovid (Publius Ovidius Naso)

    I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.
    Jimmy Carter (James Earl Carter, Jr.)
