Lesueuria vitrea is a species of comb jelly in the family Bolinopsidae. It is the type species of the genus Lesueuria and is found in the Mediterranean Sea. Its type specimen was collected in the Bay of Nice. [1]
Lesueuria vitrea was first described by French zoologist Henri Milne-Edwards in 1841, when it was designated as the type species of the newly established genus Lesueuria. [2] [3] Over the next century, several other zoologists collected or viewed the species and included it in their lists. Alessandro Spagnolini in 1870 believed the species may be what is now called Bolinopsis infundibulum , William M'Intosh claimed to have found it in Scotland in 1888, and Fanny Moser expanded the genus by adding L. hyboptera and L. tiedemanni in 1908. Ole Theodor Jensen Mortensen agreed with Spagnolini in 1912, theorizing that L. vitrea was either a rare deep sea species, a heteromorphic form of B. infundibulum, or specimens of B. infundibulum that lost most of their lobes through damage or mutilation. In 1957, Lesueuria vitrea was included in a species compendium, but with the note non revue depuis — "never seen again" since its first description. A series of dive explorations in 1957 in the Bay of Nice, where the species was originally reported, did not find any specimens; they did, however, find several of Bolinopsis hydatina in the range. The genus Lesueuria was assigned to the family Bolinopsidae in 1995. [4]
Despite its status as the name-bearing type of the genus Lesueuria, Milne-Edwards did not submit any of the type material of the species for preservation or study. Because of the likelihood that it is in fact a mutilated member of the genus Bolinopsis , [5] the name Lesueuria vitrea is considered uncertain, or a nomen dubium , by the World Register of Marine Species. [1]
In Milne-Edwards' original description, he noted the species' four auricles which look like ribbons, and its simple oral lobes. [2] He also described a sensory organ but was unable to identify its exact nature. He interpreted several fibers that radiated from the organ as nerve structures, but they were later determined to be unrelated muscle fibers. [6]

Platecarpus is an extinct genus of aquatic lizards belonging to the mosasaur family, living around 84–81 million years ago during the middle Santonian to early Campanian, of the Late Cretaceous period. Fossils have been found in the United States and possible specimens in Belgium and Africa. A well-preserved specimen of Platecarpus shows that it fed on moderate-sized fish, and it has been hypothesized to have fed on squid, and ammonites as well. Like other mosasaurs, it was initially thought to have swum in an eel-like fashion, although another study suggests that it swam more like modern sharks. An exceptionally well-preserved specimen of P. tympaniticus known as LACM 128319 shows skin impressions, pigments around the nostrils, bronchial tubes, and the presence of a high-profile tail fluke, showing that it and other mosasaurs did not necessarily have an eel-like swimming method, but were more powerful, fast swimmers. It is held in the Natural History Museum of Los Angeles County. Isotopic analysis on teeth specimens has suggested that this genus and Clidastes may have entered freshwater occasionally, just like modern sea snakes.
The Mascarene parrot or mascarin is an extinct species of parrot that was endemic to the Mascarene island of Réunion in the western Indian Ocean. The taxonomic relationships of this species have been subject to debate; it has historically been grouped with either the Psittaculini parrots or the vasa parrots, with the latest genetic study favouring the former group.
The Rodrigues parrot or Leguat's parrot is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus, based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated.
Edwardsia is a genus of sea anemones, the type of the family Edwardsiidae. They have eight mesenteries and live in tubes in the sand. The name, in Neo-Latin, commemorates the French zoologist Henri Milne-Edwards.
Paludinella is a genus of minute salt marsh snails with an operculum, aquatic gastropod mollusks or micromollusks, in the family Assimineidae.
Archaeoniscus is a genus of prehistoric isopods that first appeared during the Bajocian stage of the Middle Jurassic. It is a widespread genus with a paleogeographic distribution encompassing the continental margin environments of the central Atlantic Ocean and the western Tethys Ocean. Fossils of Archaeoniscus suggest that this genus lived in diverse aquatic habitats, including the marine, paralic, and freshwater environments. While earlier descriptions suggested that it may have had an ectoparasitic association with fishes, some researchers argue that at least two species, A. aranguthyorum and A. coreaensis, lived a benthic free-living lifestyle based on morphological characteristics that are either unsuitable for or unrelated to parasitic behavior.
Bolinopsidae is a family of ctenophores.
Teuthowenia megalops, sometimes known as the Atlantic cranch squid, is a species of glass squid from the subarctic and temperate waters of the northern Atlantic Ocean. They are moderately sized squid with a maximum mantle length of 40 cm (16 in). Their very large eyes are the source for the specific name megalops. Like other members of the genus Teuthowenia, they are easily recognizable by the presence of three bioluminescent organs (photophores) on their eyeballs.
Leucothea is a genus of ctenophores in the monotypic family Leucotheidae.
Ocypode brevicornis is a species of ghost crab native to the Indian Ocean, from the Gulf of Oman to the Nicobar Islands. They are relatively large ghost crabs with a somewhat trapezoidal body. The carapace reaches a length of 41 mm (1.6 in) and a width of 50 mm (2.0 in). They are a mottled brown to yellow in coloration. Like other ghost crabs, one of their claws is much larger than the other. Their eyestalks are large and elongated, tipped with prolongations at the tip known as styles. They are common inhabitants of open sandy beaches, living in burrows in the intertidal zone.
The terms Anthropopithecus and Pithecanthropus are obsolete taxa describing either chimpanzees or archaic humans. Both are derived from Greek ἄνθρωπος and πίθηκος, translating to "man-ape" and "ape-man", respectively.
Bolinopsis infundibulum, commonly known as the common northern comb jelly, is a species of comb jelly in the family Bolinopsidae. It is found in the northern Atlantic Ocean and was first described by the Danish naturalist Otto Friedrich Müller in 1776.
Clavularia crassa is a species of colonial soft coral in the family Clavulariidae. It is found in the eastern Atlantic Ocean and the Mediterranean Sea. It was first described in 1848 by the French zoologist Henri Milne-Edwards from a specimen collected off the coast of Algeria.

Elornis is an extinct genus of flamingo from the Late Oligocene of Ronzon, France. Although the name was coined in the 1850s, the name remained a nomen nudum until later publications by French zoologist Henri Milne-Edwards. Elornis has been historically considered to be a member of the Phoenicopteridae, but more recent research suggests it may have been more basal. Research on this taxon is however difficult as the current whereabouts of the fossil material are unknown, limiting data to the description and illustrations of Milne-Edwards.
