Infundibulum (gastropod)
''Infundibulum'' is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails. Description The conical shell is false-umbilicate. The periphery is angular. The base of the shell is nearly flat, or concave. The outer surface is smooth, costate or granular. The outer lip is not lirate within. The columella is inserted in the center of the axis. It is more or less folded above, its edge straight, oblique, not toothed, and without a notch at its base. Species Species within the genus ''Infundibulum'' include: * '' Infundibulum concavum'' (Gmelin, 1791) * ''Infundibulum tomlini'' (Fulton, 1930)Marshall B. A. (2000).

Pierre Denys De Montfort
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. He was inspired by a description from 1783 of an eight-metre long tentacle found in the mouth of a sperm whale. 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.

Description The size of the shell varies between 18 mm and 40 mm. The solid, false-umbilicate shell has an elate-conic shape. The spire has nearly rectilinear outlines. The about 9 whorls are planulate, the body whorl is carinated.

''Tectus niloticus'' is no longer classified as a ''Trochus'' species, and it is no longer classified in the family Trochidae; it is now placed in the family Tegulidae.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
