High Quality Content by WIKIPEDIA articles! Xenodiscula is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Sagdidae. In biology, a genus (plural: genera) is a taxonomic unit (a taxon) used in the classification of living and fossil organisms, which is an example of definition by genus and differentia. The term comes from Latin genus "descent, family, type, gender", cognate with Greek: – genos, "race, stock, kin". The composition of a genus is determined by a taxonomist. The standards for genus classification are not strictly codified, and hence different authorities often produce different classifications for genera. In the hierarchy of the binomial classification system, genus comes above species and below family.
