Pituophis
''Pituophis'' is a genus of nonvenomous colubrid snakes, commonly referred to as gopher snakes, pine snakes, and bullsnakes, which are endemic to North America. They are often yellow or cream in color with dark spots and a dark line across their face. Some species can exceed seven feet in length. Gopher snakes can live for 15 years. The gopher snake is commonly misidentified as a rattlesnake because of its similar coloration and its defensive behavior when feeling threatened. A scared gopher snake will flatten its head, hiss loudly, and shake its tail rapidly, doing a very convincing rattlesnake imitation. Nomenclature The genus name ''Pituophis'' is a Latinized modern scientific Greek compound Πιτυόφις : "pine snake"; from (pítus, "pine"), and (óphis, "snake"). Geographic range Species and subspecies within the genus ''Pituophis'' are found throughout Mexico, the Southern and Western United States and Western Canada. Conant R (1975).

Comstock Publishing Associates. (7th printing, 1985). 1,105 pp. . (''Pituophis catenifer'', pp. 588-609, Figures 171.-175., Map 46.) ( more here). ''Pituophis catenifer'' is a species of non-venomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, ''P. c. catenifer'', described here. This snake is often mistaken for the prairie rattlesnake (''Crotalus viridus''), but can be easily distinguished from a rattlesnake by the lack of a tail rattle, no black-and-white banding on its tail, and by the shape of its head, which is narrower than a rattlesnake's. Additionally, rattlesnakes (and indeed most vipers) possess a large venom gland located behind each eye, giving their heads a much rounder, more angular shape, as opposed to the more cylin ...

Pacific Gopher Snake
''Pituophis catenifer catenifer'' is a subspecies of large non-venomous colubrid snake native to the western coast of North America. Pacific gopher snakes are one of California's most common snake species. They often get confused for rattlesnakes because they mimic similar patterns and defense mechanisms. As a result, gopher snakes can often avoid confrontation without needing to rely on their non-venomous nature for survival. Description Pacific gopher snake adults range in size from in total length. However, most of the subspecies reach a length of . The hatchlings are relatively long, and they have been recorded at lengths upward of . The Pacific gopher snake has a base color ranging from yellow to dark brown and has a gray coloring on the sides of the body. It is a spotted snake, with the spots being dark brown. Usually there are 41 to 99 spots on the body, while the tail spots range from 14 to 33. The side of the body has 2 or 3 rows of alternating black and brown spot ...

Pituophis Catenifer Affinis

Colubrid
Colubridae (, commonly known as colubrids , from , 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. Colubrid snakes are found on every continent except Antarctica. Description Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters. A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals. However, the bites of some can escalate quickly to emergency situations. Furthermore, within the Colubridae, the South African boomslang and twig snakes, as well as the Asian keelback snakes ('' R ...

Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, althoug ...

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, 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 unfavorable c ...

Laurence M
Laurence is in modern use as an English masculine and a French feminine given name. The modern English masculine name is a variant of Lawrence and originates from a French form of the Latin ''Laurentius'', a name meaning "man from Laurentum". The French feminine name Laurence is derived from the same source and is used in French-speaking countries as a form of the masculine '' Laurent''. The name was used in the Middle Ages for both males and females in honor of Saint Laurence, one of the seven deacons of Rome. In England, it was also given in reference to Saint Laurence of Canterbury. In other languages: Lorenzo ( Italian, Spanish), Lorenz ( German). In Ireland, Laurence has traditionally been used as an Anglicization of the Irish masculine name Lorcan or Lorcán. Usage Laurence, used as a spelling variant of the more popular Lawrence, was in regular use for boys in the Anglosphere since the medieval era.

Charles Frédéric Girard
Charles Frédéric Girard (; 8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Biography Girard was born on 8 March 1822 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 Wa ...
