Norrisia is a genus of sea snail, a marine gastropod mollusk in the family Tegulidae. [1] [2] [3]
Norrisia is a monotypic genus and its only species is Norrisia norrisii .
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea. The term true conchs, being a common name, does not have an exact meaning. It may refer generally to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 23 extant, and 10 extinct genera.
The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Cerithiidae, common name the cerithiids or ceriths, is a large family of medium-sized marine gastropods in the clade Sorbeoconcha.
Bittium is a genus of very small sea snails, marine gastropod molluscs in the family Cerithiidae, the horn snails.
Trimastix is a genus of excavates, the sole occupant of the order Trimastigida. Trimastix are bacterivorous, free living and anaerobic. When first observed in 1881 by William Kent, the morphology of Trimastix was not well described but over time the oral structure and flagellar organization have become clearer. There are few known species, and the genus's role in the ecosystem is largely unknown. However, it is known that they generally live in marine environments within the tissues of decaying organisms to maintain an anoxic environment. Much interest in this group is related to its close association with other members of Anaeromonadea. Like other members of this order, these organisms do not have classical mitochondria. As such, much of the research involving these microbes is aimed at investigating the evolution of mitochondria.
Campanilidae are a taxonomic family of sea snails, marine gastropod molluscs in the clade Sorbeoconcha.
Euspira is a genus of medium-sized sea snails, marine gastropod molluscs in the family Naticidae, the moon snails.
The marine snail Norrisia norrisii is a medium-sized gastropod mollusk within the family Tegulidae. It has several common names, including Norris's top snail, Norris's topsnail, norrissnail, smooth brown turban snail, or kelp snail. It was first described by G.B. Sowerby I under the name Trochiscus norrisii.
Lepetella is a genus of very small deep-sea sea snails or limpets, marine gastropod mollusks in the family Lepetellidae.
Cacozeliana icarus is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae.
Royella sinon is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae.
Cacozeliana is a genus of sea snails, marine gastropod mollusks in the family Cerithiidae.
Gourmya is a genus of sea snails, marine gastropod mollusks in the family Cerithiidae.
Royella is a genus of sea snails, marine gastropod mollusks in the family Cerithiidae.
Cerithiopsis is a genus of very small sea snails, marine gastropod mollusks or micromollusks in the family Cerithiopsidae.
Kelletia is a genus of large sea snails, whelks, a marine gastropod molluscs in the family Buccinidae, the true whelks.
Tegulidae is a family of small to large sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Thomas Norris FRAS was an English businessman, art collector, natural historian and astronomer, born at Croston in Lancashire. Joining the Bury firm of Peel, Yates and Co. as a book-keeper at the age of twenty, he eventually became a partner and amassed a considerable fortune from its success in the textile and calico-printing businesses. Amongst his partners at the firm was the businessman and politician Sir Robert Peel, whose son, also named Sir Robert Peel, served twice as Prime Minister of the United Kingdom. Norris was reputedly a regular and welcome visitor at the latter's home in Whitehall Gardens.
