Crotaphytinae
The Crotaphytidae, or collared lizards, are a family of desert-dwelling reptiles native to the Southwestern United States and northern Mexico. Alternatively they are recognized as a subfamily, Crotaphytinae, within the clade Pleurodonta. They are very fast-moving animals, with long limbs and tails; some species are capable of achieving bipedal running at top speed. This species is carnivorous, feeding mainly on insects and smaller lizards. The two genera contain 12 species. Technical characters *Femoral pores present *Interparietal scale small (distinctly smaller than ear opening) *Never have an enlarged middorsal scale row or fringe *Never have a divided rostral scale *No bony spines or projecting ridges on their heads *No scales projecting over their ears, and no scales forming a prominent fringe on sides of toes as in Phrynosomatidae Species Genus ''Gambelia'' ''Dahms Tierleben''. www.dahmstierleben.de/systematik/Reptilien/Squamata/Iguania/crotaphytidae.

Rostral Scale
The rostral scale, or rostral, in snakes and other scaled reptiles is the median plate on the tip of the snout that borders the mouth opening. Wright AH, Wright AA (1957).

The species is endemic to the Western United States. Description ''C. bicinctores'' is very similar to the common collared lizard, ''Crotaphytus collaris'', in shape and size, but it lacks the bright extravagant colors.

It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest.

Venerable Collared Lizard
The venerable collared lizard (''Crotaphytus antiquus'') is a species of lizard in the genus '' Crotaphytus'' in the family Crotaphytidae. The species is native to northern Mexico. Geographic range ''C. antiquus'' is restricted to the area of Sierra San Lorenzo, Texas, and Sierra Solis in extreme southwestern Coahuila state. Reproduction ''C. antiquus'' is oviparous Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother.

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 ...

Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gambelia Wislizenii
The long-nosed leopard lizard (''Gambelia wislizenii'') is a species of relatively large North American lizard in the family Crotaphytidae. ''Gambelia wislizenii'' ranges in snout-to-vent length (SVL) from . It has a large head, a long nose, and a long round tail that can be longer than its body. It is closely related to the blunt-nosed leopard lizard (''Gambelia sila''), which closely resembles the long-nosed leopard lizard in body proportions, but has a conspicuously blunt snout. The species ''G. wislizenii'', once considered part of the genus '' Crotaphytus'', is under moderate pressure because of habitat destruction but is categorized as "least concern". Etymology The specific name or epithet, ''wislizenii'', is in honor of the German-American surgeon and naturalist Frederick Adolph Wislizenus, who caught the first specimen near Santa Fe, New Mexico. Description ''Gambelia wislizenii'' has granular dorsal scales that can be white, cream, or gray with irregular brown or d ...

Leonhard Hess Stejneger
Leonhard Hess Stejneger (30 October 1851 – 28 February 1943) was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians. Wetmore, Alexander (1945). "Leonhard Hess Stejneger (1851-1943)". ''Biographical Memoir. Nat. Acad. Sci.'' 24: 145-195PDF/ref> Early life and family Stejneger was born in Bergen, Norway. His father was Peter Stamer Steineger, a merchant and auditor; his mother was Ingeborg Catharine (née Hess). Leonhard was the eldest of seven children. His sister Agnes Steineger was a Norwegian artist. Until 1880, the Steineger family had been one of the wealthy families in Bergen; at that time business reverses led to the father declaring bankruptcy. Stejneger attended the Smith Theological School in Bergen from 1859 to 1860, and Bergen Latin School until 1869. His interests in zoology developed early. By age sixteen he had a pr ...

Gambelia Sila
''Gambelia sila'', commonly known as the blunt-nosed leopard lizard, is a species of lizard in the family Crotaphytidae. The species is endemic to southern California. Taxonomy ''Gambelia sila'' was originally described by Leonhard Stejneger in 1890 as ''Crotaphytus silus''. The type locality is Fresno, California. In 1900 Cope believed the lizard to be a subspecies of the long-nosed leopard lizard, ''C. wislizenii'', and classified it as ''C. w. silus''. Based on differences in bony plates on the head, the presence or absence of gular folds, and head shape, ''Crotaphytus silus'' was reclassified into the genus ''Gambelia'' by H.M. Smith in 1946, retaining the specific name "''silus'' ". ''Gambelia'' is the generic name for leopard lizards in the family Crotaphytidae. ''Gambelia sila'' is similar to the lizards in the genus ''Crotaphytus'', the difference is that the latter have fracture planes in their tails. This allows the tails to break off when grasped by predators. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
