Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pierre Denys de Montfort, also sometimes spelled "Pierre Dénys de Montfort", (1766–1820) was a French naturalist, in particular a malacologist, remembered today for his pioneering inquiries into the existence of the gigantic octopuses.

Montfort was author of ''Conchyliologie systématique, et classification méthodique de coquilles'' (2 vols., Paris 1808–1810) and of ''Histoire Naturelle Générale et Particulière des Mollusques'' (2 vols., Paris 1801–1802) published as an addendum to the comte de Buffon's '' Histoire Naturelle, générale et particulière''. He appears also to have been the author of ''Petit vocabulaire à l'usage des Français et des Alliés, renfermant les noms d'une partie des choses les plus essentielles à la vie en plusieurs langues: français, Latin, hébreu, hollandais, allemand, anglais, espagnol, italien, etc par M.
