In the genus Ensatinas, she has been observed to coil around them and press her throat area against them, effectively massaging them with a mucous secretion.

The challenge to the status has focused on the Agnostina partly because juveniles of one genus have been found with legs greatly different from those of adult trilobites, suggesting they are not members of the lamellipedian clade, of which trilobites are a part.

The family also has important ornamentals, mainly from the dominant genus Allium, but also including genera such as Ipheion.

Heller's names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis.

Much rethinking has come to be regarded as only a special case of the property genus.

The Passenger Pigeon is a member of the Columbidae family ( pigeons and doves ) that has been assigned to the genus Ectopistes.

As the senior synonym, Cuvier's name has precedence, so applying modern rules for the combination of the genus name and the specific epithet, the valid species name became Ptéro-Dactyle antiquus.

Unaware of Rafinesque's publication Cuvier himself in 1819 again Latinized the genus, but the specific name he then gave, longirostris, has to give precedence to von Soemmerring's antiquus.

However, it has been difficult to determine exactly of what genus and species P. micronyx might be the juvenile form.

It has sometimes been placed in the genus Diopecephalus because Harry Govier Seeley based this genus partly on the P. longicollum material.

Hybrids said to be between Amaryllis belladonna and Brunsvigia josephinae have been called × Amarygia, Neither hybrid genus name is accepted by the World Checklist of Selected Plant Families.

Fossil remains of beavers are found in the peat and other superficial deposits of Britain and the continent of Europe ; while in the Pleistocene formations of Britain and Siberia, remains of a giant extinct beaver have been found, Trogontherium cuvieri, representing a genus by itself.

Most of the kinds commonly eaten fresh or dried, those of the genus Phaseolus, come originally from the Americas, being first seen by a European when Christopher Columbus, during his exploration, of what may have been the Bahamas, found them growing in fields.

These characteristics originally defined the genus, but not all such species are closely related, and many have been moved to other genera.

" Chipmunks have also been referred to as " striped squirrels ," " chippers ," " munks ," " timber tigers ," or " ground squirrels ," although the name " ground squirrel " usually refers to other squirrels, such as those of the genus Spermophilus.

Many slight variants have been discovered since then, including various alternative mitochondrial codes, and small variants such as translation of the codon UGA as tryptophan in Mycoplasma species, and translation of CUG as a serine rather than a leucine in some members of the genus Candida ( see the article on Candida albicans ).

Clerodendrum was once a genus of over 400 species, but by 2010, it had been narrowed to about 150.

It is the sole living representative of its family ( Ornithorhynchidae ) and genus ( Ornithorhynchus ), though a number of related species have been found in the fossil record.

Fully mature Pterodactylus specimens remain unknown, or may have been mistakenly classified as a different genus.

Ardipithecus is a fossil hominoid, described by its discoverers as a very early hominin genus.

This fossil was originally described as a species of Australopithecus, but White and his colleagues later published a note in the same journal renaming the fossil under a new genus, Ardipithecus.

Bulbs sold as amaryllis and described as " ready to bloom for the holidays " belong to the allied genus Hippeastrum.

The genus Candida and species C. albicans were described by botanist Christine Marie Berkhout in her doctoral thesis at the University of Utrecht in 1923.

Despite a large number of Homo fossils finds, chimpanzee fossils ( genus Pan ) were not described until 2005.

A grape is a fruiting berry of the deciduous woody vines of the botanical genus described as Vitis.

Orcinus orca is the only recognized extant species in the genus Orcinus, one of many animal species originally described by Linnaeus in 1758 in Systema Naturae.

It was described as a new genus and species by Robert Broom of the Transvaal Museum.

Shaw assigned it as a Linnaean genus name when he initially described it, but the term was quickly discovered to belong already to the wood-boring ambrosia beetle ( genus Platypus ).

This was supported by the description of an additional pterosaur egg belonging to the genus Darwinopterus, described in 2011, which also had a leathery shell and, also like modern reptiles but unlike birds, was fairly small compared to the size of the mother.

Male Pteranodon sternbergi, the older species of the two described to date ( and sometimes placed in the distinct genus Geosternbergia ), had a more vertical crest with a broad forward projection, while their descendants, Pteranodon longiceps, evolved a narrower, more backward-projecting crest.

French zoologist Frédéric Cuvier initially described the red panda in 1825, and classified it as a close relative of the raccoon ( Procyonidae ), though he gave it the genus name Ailurus, " cat ", based on superficial similarities with domestic cats.

There are 600 described species of this single genus.

The genus contains at least 68 described extant taxa, but the true number of species is a matter of debate.

The fossil was subsequently described as Plesiosaurus dolichodeirus and is the type specimen ( holotype ) of the species, which itself is the type species of the genus.

The Banksia genus was first described and named by Carolus Linnaeus the Younger in his April 1782 publication Supplementum Plantarum ; hence the full name for the genus is " Banksia L. f ." The genus name honours the English botanist Sir Joseph Banks, who collected the first Banksia specimens in 1770, during James Cook's first expedition.

They were originally described by Walcott as separate fossils under the genus name Helenia, ( Walcott's wife was named Helena and his daughter Helen ); Runnegar adopted the name helen when they were recognized as part of the hyolith organism.

The best-known is the type genus Peripatus, which was described as early as 1825 and which, in English-speaking countries, stands representative for all velvet worms.

In the taxonomical structure " genus → species ", a species is described as sui generis if its genus was created to classify it ( i. e. its exceptional uniqueness at the time of classification necessitated the creation of a new genus, the sole member of which was initially the sui generis species ).

The origin of the name is uncertain, but it could be a corruption of'm ' oganwo ', the name used by the Yoruba and Ibo people of West Africa to described trees of the genus Khaya, which is closely related to Swietenia.
