Trachylepis Maculata
''Trachylepis maculata'', the spotted mabuya, is a species of skink in the genus ''Trachylepis'' recorded from Demerara in Guyana, northern South America. It is placed in the genus ''Trachylepis'', which is otherwise mostly restricted to Africa, and its type locality may be in error. It is an unstriped, olive-brown, grayish animal, with dark spots all over the body.Mausfeld and Vrcibradic, 2002, p. 293 Its taxonomic history is complex due to confusion with ''Trachylepis atlantica'' from the Atlantic Ocean island of Fernando de Noronha and doubts regarding its type locality. ''T. maculata'' was first described, as ''Tiliqua maculata'', by Gray in 1839 on the basis of three specimens said to be from Demerara, Guyana. On the same page, Gray described ''Tiliqua punctata'' from the island of Fernando de Noronha off Brazil. In 1887, the two names were considered by Boulenger to pertain to the same species, which was initially named ''Mabuya punctata'' but renamed ''Mabuya maculata'' by ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Scales
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government.

Reptiles Of Guyana
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Trachylepis Perrotettii
''Trachylepis'' is a skink genus in the subfamily Mabuyinae found mainly in Africa. Its members were formerly included in the "wastebin taxon" ''Mabuya'', and for some time in ''Euprepis''. As defined today, ''Trachylepis'' contains the clade of Afro-Malagasy mabuyas. The genus also contains a species from the Brazilian island of Fernando de Noronha, '' T. atlantica'', and may occur in mainland South America with ''Trachylepis tschudii'' and ''Trachylepis maculata'', both poorly known and enigmatic. The ancestors of ''T. atlantica'' are believed to have rafted across the Atlantic from Africa during the last 9 million years. The generic name ''Trachylepis'' literally means "rough-scaled", referring to the fact that most of the species, though superficially smooth-scaled, have three or more slight longitudinal keels on their dorsal scales. Species The following species are recognized as being valid (listed alphabetically by specific name). *''Trachylepis acutilabris'' – wedg ...

Mabuya Falconensis
''Mabuya'' is a genus of long-tailed skinks restricted to species from various Caribbean islands. They are primarily carnivorous, though many are omnivorous. The genus is viviparous, having a highly evolved placenta that resembles that of eutherian mammals. Formerly, many Old World species were placed here, as ''Mabuya'' was a kind of " wastebasket taxon". These Old World species are now placed in the genera ''Chioninia'', '' Eutropis'', and ''Trachylepis''. Under the older classification, the New World species were referred to as "American mabuyas", and now include the genera ''Alinea'', '' Aspronema'', '' Brasiliscincus'', ''Capitellum'', '' Maracaiba'', ''Marisora'', '' Varzea'', and ''Copeoglossum''. Most species in this genus are feared to be possibly extinct due to introduced predators. Species Listed alphabetically by specific name.

Frontal Scale
Frontal scale refers to the scales of a reptile which lie in the general region of the forehead of a snake, more specifically between the eyes and to the anterior of this area. These are analogous to the ''frontal bone'' on a human which corresponds to the forehead. Snake scales attached to the frontals and to its anterior are called prefrontals.

Supraocular Scales
In scaled reptiles, supraocular scales are (enlarged) scales on the crown immediately above the eye.Mallow D, Ludwig D, Nilson G. 2003. True Vipers: Natural History and Toxinology of Old World Vipers. Malabar, Florida: Krieger Publishing Company. 359 pp. . The size and shape of these scales are among the many characteristics used to differentiate species from each another. In many species of boids and viperids, the supraoculars are heavily fragmented. In others, such as the colubrids and elapids, they are enlarged.
