Crotaphytus
''Crotaphytus'' is a genus of lizards commonly known as collared lizards. They are a genus of small to medium-sized predators indigenous to the American southwest, Baja peninsula, and Mexico. They can be as small as 8" or as long as 14″ (20-36cm), and are characterized by distinct bands of black or brown around their neck, thus their common name.

Lizards
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as bi ...

Crotaphytus Reticulatus
''Crotaphytus reticulatus'', commonly called the reticulate collared lizard, is a species of moderately sized lizard in the family Crotaphytidae. The species is native to semiarid, rocky regions of the Tamaulipan mezquital. Its range includes the US state of Texas and the Mexican states of Coahuila, Nuevo León, and Tamaulipas. Of all the species in the family Crotaphytidae, ''C. reticulatus'' is the only species which is not restricted to rocky habitats. Description ''Crotaphytus reticulatus'' is a tan to brown lizard with reticulations covering most of its dorsum, limbs, and tail. Some of these reticulations are filled with black pigmentation. Unlike the rest of the species in the genus ''Crotaphytus'', there is no color difference between males and females of ''C. reticulatus'' except during the breeding season. During this time, males develop a bright yellow coloration on their chests. The collars on ''C. reticulatus'' are faint and the anterior collar is complete ventr ...

John Edwards Holbrook
John Edwards Holbrook (December 31, 1796 – September 8, 1871) was an American zoologist, herpetologist, physician, and naturalist, born in Beaufort, South Carolina, the son of Silas Holbrook, a teacher, and Mary Edwards. Although Holbrook's memoir, written by his medical partner, and his tombstone both give the date 1794 for his birth, this is incorrect. Holbrook received his A.B. degree from Brown University in 1815, and his M.D. from the University of Pennsylvania in 1818. In 1827, he married Harriott Pinckney Rutledge (1802–1863), granddaughter of John Rutledge and a member of the Middleton-Rutledge-Pinckney family. He provided the first comprehensive illustrated account of North American amphibians and reptiles in the two editions of his ''North American Herpetology; or, A Description of the Reptiles Inhabiting the United States''. The first edition in four volumes (1836–1840) is very rare because Holbrook attempted to destroy all copies in a bonfire in his backyard over ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nota Bene
(, or ; plural form ) is a Latin phrase meaning "note well". It is often abbreviated as NB, n.b., or with the ligature and first appeared in English writing . In Modern English, it is used, particularly in legal papers, to draw the attention of the reader to a certain (side) aspect or detail of the subject being addressed. While ''NB'' is also often used in academic writing, ''note'' is a common substitute. The markings used to draw readers' attention in medieval manuscripts are also called marks. The common medieval markings do not, however, include the abbreviation ''NB''. The usual medieval equivalents are anagrams from the four letters in the word , the abbreviation DM from ("worth remembering"), or a symbol of a little hand (☞), called a manicule or index, with the index finger pointing towards the beginning of the significant passage.Raymond Clemens and Timothy Graham, Introduction to Manuscript Studies (Ithaca: Cornell University Press, 2007), p. 44.

Richard R
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish.

Joseph Richard Slevin
Joseph Richard Slevin (September 13, 1881 – February 17, 1957) was an American herpetologist and the second curator of herpetology at the California Academy of Sciences, with which he was affiliated for over 50 years. He collected reptile and amphibian specimens from around the world, notably in the Galápagos Islands in a 17-month expedition, and was largely responsible for re-growing the Academy's herpetological collection following its destruction in the 1906 San Francisco earthquake. He wrote or co-wrote nearly 60 scientific papers, and is commemorated in the scientific names of over a dozen species or subspecies of animals and plants. Early life Slevin was born in San Francisco, California, and attended St. Ignatius High School. His father, Thomas E. Slevin, was an amateur ornithologist and member of the California Academy of Sciences. Joseph studied classical languages at Saint Mary's College in Kansas, then enlisted in the United States Navy.

John Van Denburgh
John Van Denburgh (August 23, 1872 – October 24, 1924) was an American herpetologist from California (who also used the name Van Denburgh in publications, hence this name is used below). Biography Van Denburgh was born in San Francisco and enrolled at Stanford University in 1891. As of 1895, he organized the herpetology department of the California Academy of Sciences.
