Mattheus Marinus Schepman
Mattheus Marinus Schepman (17 August 1847 – 19 November 1919) was a Dutch people, Dutch malacologist. He was one of the foremost collectors of mollusc shells in the Netherlands, and was also high on the overall list of European collectors. Dutch collectors developed an interest in natural history specimens that were collected on worldwide expeditions since the 16th century. An interest in conchology led to numerous shell publications. In 1934 the Nederlandse Malacologische Vereniging (Netherlands Malacological Society) was founded. In commemoration of its 75th anniversary, a book honoring in detail the work of Mattheus Schepman was published. His research Schepman was both a collector and a methodical scientist, which combination "made his collection of great value to the entire malacological community." He was given the opportunity to study a collection by Max Carl Wilhelm Weber, Director of the Zoological Museum Amsterdam, Zoölogisch Museum Amsterdam (ZMA). Many of the speci ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
