Holbrookia Propinqua Propinqua
''Holbrookia'' is a genus of earless lizards, known commonly as the lesser earless lizards, in the family Phrynosomatidae. The genus contains six recognized species, which are found throughout the Southwestern and Central United States and northern Mexico. They are characterized by having no external ear openings, presumably to prevent soil from entering their bodies when they are digging. Etymology The generic name, ''Holbrookia'', is in honor of American zoologist John Edwards Holbrook. Description Lesser earless lizards grow to about 2.0-2.5 in (50–65 mm) snout-to-vent length, plus a tail of 3–4 in (75–100 mm). They are typically grey or tan in color, with black blotching. The males usually have blue patches on either side of their bellies, whereas the females do not. Females often change to have bright orange patches when gravid. Behavior ''Holbrookia'' species are diurnal, basking lizards. They spend the vast majority of their time sunning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Lizard
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 a ...

Holbrookia Subcaudalis
''Holbrookia subcaudalis'', commonly known as the southern spot-tailed earless lizard, is a species of lizard in the genus ''Holbrookia''. It was previously considered a subspecies of Holbrookia lacerata. Geographic range It is found in northern Mexico and the United States in southern Texas. Description The southern spot-tailed earless lizard is overall light grayish tan in color, with two paravertebral rows of transverse light-edged dark blotches, one row down either side of the back and a second lateral row of dark, pale-edged blotches that are usually not connected to the paravertebral blotches. Adults are in total length. They have round, dark spots on the ventral surface of the tail, a characteristic which gives them both their common and scientific names.

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Marie Firmin Bocourt
Marie Firmin Bocourt (19 April 1819 – 4 February 1904) was a French zoologist and artist. As a young man, he worked as a preparateur for the zoologist Gabriel Bibron (1805–1848), later serving as a museum artist. In 1861, he was sent to Thailand (then called Siam), where he explored the fauna and brought back an important collection of specimens. He collaborated with Auguste Duméril (1812–1870) on a series called ''Mission scientifique au Mexique et dans l'Amérique Centrale'', a result of Bocourt's scientific expedition to Mexico and Central America in 1864–1866, in one part during the French Intervention in Mexico led by Napoleon III. Auguste Duméril died in 1870, and the project was continued by Bocourt with assistance from Léon Vaillant (1834–1914), François Mocquard (1834–1917) and Fernand Angel (1881–1950). With Vaillant, he published a study on fishes, "''Études sur les poissons'' ", that was included in ''Mission scientifique au Mexique et dans l'Améri ...
