Taxa named by John Edward Gray

Tapirs ( ) are large herbivorous mammals belonging to the family Tapiridae. They are similar in shape to a pig, with a short, prehensile nose trunk (proboscis). Tapirs inhabit jungle and forest regions of South and Central America and Southeast Asia. They are one of three extant branches of Perissodactyla (odd-toed ungulates), alongside equines and rhinoceroses. Only a single genus, Tapirus, is extant. Tapirs migrated into South America during the Pleistocene epoch from North America after the formation of the Isthmus of Panama as part of the Great American Interchange. Tapirs were present acr

Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs, and lack hind limbs altogether. In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult states. Sirens are found only in the Southeastern United States and northern Mexico.

The family Proteidae is a group of aquatic salamanders found today in the Balkan Peninsula and North America. The range of the genus Necturus (commonly known as waterdogs or mudpuppies) runs from southern central Canada, through the midwestern United States, east to North Carolina and south to Georgia and Mississippi. The range of the olm, the only extant member of the genus Proteus, is limited to the Western Balkans. The fossil record of the family extends back to the Late Cretaceous, with Paranecturus being known from the Maastrichtian of North America, and Bishara from the Santonian-Campani

The rock-wallabies are the wallabies of the genus Petrogale.

Bitis is a genus of vipers found in Africa and the southern Arabian Peninsula. It includes the largest and the smallest vipers in the world. Members are known for their characteristic threat displays that involve inflating and deflating their bodies while hissing and puffing loudly. The type species for this genus is B. arietans, which is also the most widely distributed viper in Africa. Currently, 18 species are recognized.

The Antilocapridae are a family of ruminant artiodactyls endemic to North America. Their closest extant relatives are the giraffids. Only one species, the pronghorn (Antilocapra americana), is living today; all other members of the family are extinct. The living pronghorn is a small ruminant mammal resembling an antelope.

Potoroidae is a family of marsupials, small Australian animals known as bettongs, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby.

species of lagomorphs (Lagomorpha)

The hickatee (Dermatemys mawii) or in Spanish tortuga blanca ("white turtle"), also called the Central American river turtle, is the only living species in the family Dermatemydidae. The species is found in the Atlantic drainages of Central America, specifically Belize, Guatemala, southern Mexico, and probably Honduras. It is a relatively large-bodied species, with records of straight carapace length and weights of ; although most individuals are smaller. This is a herbivorous and almost completely aquatic turtle that does not surface to bask. Bizarrely for reptiles, the eggs can remain viable

Potamochoerus (from Ancient Greek ποταμός (potamós), meaning "river", and χοῖρος (khoîros), meaning "pig") is a genus in the pig family (Suidae). The two species are restricted to sub-Saharan Africa, although the bushpig, possibly due to introduction by humans, also occurs in Madagascar and nearby islands. Early in the 20th century, there were considered to be as many as five different species within the genus. These were gradually consolidated, until, in the 1970s, it was generally agreed that all were representatives of just a single species (P. porcus). The bushpig was again recognised as a

Lorisoidea is a superfamily of nocturnal primates found throughout Africa and Asia. Members include the galagos and the lorisids. As strepsirrhines, lorisoids are related to the lemurs of Madagascar and are sometimes included in the infraorder Lemuriformes, although they are also sometimes placed in their own infraorder, Lorisiformes Gregory, 1915.

The snubfin dolphins (Orcaella) are a genus of cetaceans containing two members: the Irrawaddy dolphin (Orcaella brevirostris) and the Australian snubfin dolphin (Orcaella heinsohni). The genus was long believed to be monotypic with the only species being the Irrawaddy dolphin; however, in 2005, supposed Irrawaddy dolphin populations inhabiting the Australian/New Guinean regions were found to be significantly different and were declared a separate new species named the Australian snubfin dolphin.

Tupaiidae is one of two families of treeshrews, the other family being Ptilocercidae. The family contains three living genera and 19 living species. The family name derives from tupai, the Malay word for treeshrew and also for squirrel which tupaiids superficially resemble. The former genus Urogale was disbanded in 2011 when the Mindanao treeshrew was moved to Tupaia based on a molecular phylogeny.
