Siliqua Patula
The Pacific razor clam, ''Siliqua patula'', is a species of large marine bivalve mollusc in the family Pharidae. Range Pacific razor clams can be found along the Pacific West Coast of North America from the eastern Aleutian Islands, Alaska, to Pismo Beach, California. They inhabit sandy beaches in the intertidal zone down to a maximum water depth of about . Description This species has an elongated oblong narrow shell, which ranges from in length in the southern portion of its range, with individuals up to found in Alaska. It is similar to the smaller Atlantic razor clam, ''Siliqua costata'', which is found on the East Coast of the United States. The name ''razor clam'' is also used for the Atlantic jackknife clam, ''Ensis directus.'' The Atlantic jackknife clam's genus, Ensis, is different than the Pacific razor clam's genus, Siliqua. However, they are both in the same family, Pharidae Pharidae is a taxonomic family of saltwater clams, marine bivalve molluscs in ...

George Brettingham Sowerby I
George Brettingham Sowerby I (12 August 1788 – 26 July 1854) was a British naturalist, illustrator and conchologist. Life He was the second son of James Sowerby. George was educated at home under private tutors, and afterwards assisted his father in the production of illustrated works on natural history. On the latter's death in 1822, he and his brother James De Carle Sowerby continued their father's work on fossil shells, publishing the latter parts of the ''Mineral Conchology of Great Britain''. He published about 50 papers on molluscs and started several comprehensive, illustrated books on the subject, the most important the ''Thesaurus Conchyliorum'', a work that was continued by his son, George Brettingham Sowerby II and his grandson George Brettingham Sowerby III. One of his first works was the cataloguing of the collection of the Earl of Tankerville. He also dealt in shells and natural history objects, his place of business being first in King Street, Covent Garden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siliqua Minima
The siliqua (plural ''siliquae'') is the modern name given (without any ancient evidence to confirm the designation) to small, thin, Roman silver coins produced in the 4th century A.D. and later. When the coins were in circulation, the Latin word ''siliqua'' was a unit, perhaps of weight defined by one late Roman writer as one twenty-fourth of a Roman solidus. The term siliqua comes from the ''siliqua graeca'', the seed of the carob tree, which in the Roman weight system is equivalent to of a scruple ( of a Roman pound or about 0.19 grams). The term has been applied in modern times to various silver coins on the premise that the coins were valued at of the gold solidus (which weighed of a Roman pound) and therefore represented a siliqua of gold in value. Since gold was worth about 12 times as much as silver in ancient Rome (in Diocletian's ''Edict of Maxmimum Prices'' of 301),Bransbourg, Giles.

Timothy Abbott Conrad
Timothy Abbott Conrad (June 21, 1803 in Trenton, New Jersey – August 9, 1877 in Trenton) was an American geologist and malacologist. Biography He was from early life an investigator of American paleontology and natural history, devoting himself to the study of the shells of the Tertiary and Cretaceous formations, and to existing species of mollusks. In 1831 he began the issue of a work on “American Marine Conchology,” and the year following published the first number of his “Fossil Shells of the Tertiary Formation,” which was never completed. A “Monography of the Family Unionidae” was issued between 1835 and 1847. The lithographed plates in his publications were in part his own work. He contributed many articles to the '' American Journal of Science'' and the ''Journal of the Philadelphia Academy of Science''. As one of the New York state geologists he prepared the geological report for 1837. He was paleontologist of the New York Geological Survey from 1838 until ...

Wilhelm Dunker
Wilhelm Dunker, full name Wilhelm Bernhard Rudolph Hadrian Dunker (21 February 1809, Eschwege – 13 March 1885, Marburg) was a German geologist, paleontologist and zoologist (specifically a malacologist). Wilhelm Dunker studied mining and metallurgical engineering in Göttingen and worked at first as a trainee with the local mining authority. Soon thereafter he was appointed a teacher of mineralogical sciences at the poly-technical school in Kassel. In 1854 he was appointed professor at the University of Marburg, at which he taught up to his death. Dunker was one of the most important malacologists of his time. He had a very extensive private collection of snails and shells, which he constantly increased by exchange with other collectors (and probably also by purchases). He maintained contacts with his contemporaries Rudolph Amandus Philippi, Ludwig Karl Georg Pfeiffer, Hugh Cuming and Johannes Albers. By exchange he also acquired numerous original specimens and typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lorenz Spengler
Lorenz Spengler (22 September 1720 – 20 December 1807) was a Danish turner and naturalist. Born in Schaffhausen, Switzerland he arrived at Copenhagen in 1743 and became a tutor to Christian VI of Denmark and later Frederick V of Denmark in the art of turning. From 1771 he was head of the Royal Art Chamber (Det Kongelige Kunstkammer), a position he held until his death in 1807.
