Henry Hemphill
Henry Hemphill (1830–1914) was an American malacologist, a biologist who studies mollusks. In particular he studied land and freshwater mollusca. His collection of land, freshwater, and marine mollusks became holdings of the California Academy of Sciences and Stanford University. He was born in Delaware in 1830. He worked as a bricklayer in San Diego 1865, after making gold prospecting trips in the western states. He collected mollusks as early as 1861. He published catalogues of shells for sale from the 1870s to 1890. He moved to Oakland around 1909. He died in 1914 on July 24 as a result of contact with arsenic. He sold and sent out material labeled with unpublished names, and introduced varieties and formal names. He often used vague terms to describe the locality of specimens. Taxa He named and described many molluscan taxa, including: * ''Fluminicola columbiana'' Hemphill in Henry Augustus Pilsbry, Pilsbry, 1899 - a freshwater snail * ''Helminthoglypta walkeriana'' (H ...

Wilmington, Delaware
Wilmington ( Lenape: ''Paxahakink /'' ''Pakehakink)'' is the largest city in the U.S. state of Delaware. The city was built on the site of Fort Christina, the first Swedish settlement in North America. It lies at the confluence of the Christina River and Brandywine Creek, near where the Christina flows into the Delaware River. It is the county seat of New Castle County and one of the major cities in the Delaware Valley metropolitan area. Wilmington was named by Proprietor Thomas Penn after his friend Spencer Compton, Earl of Wilmington, who was prime minister during the reign of George II of Great Britain. At the 2020 census, the city's population was 70,898. The Wilmington Metropolitan Division, comprising New Castle County, Delaware, Cecil County, Maryland and Salem County, New Jersey, had an estimated 2016 population of 719,887. Wilmington is part of the Delaware Valley metropolitan statistical area, which also includes Philadelphia, Reading, Camden, and other urban are ...

Oakland, California
Oakland is the largest city and the county seat of Alameda County, California, United States. A major West Coast of the United States, West Coast port, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the Bay Area and the List of largest California cities by population, eighth most populated city in California. With a population of 440,646 in 2020, it serves as the Bay Area's trade center and economic engine: the Port of Oakland is the busiest port in Northern California, and the fifth busiest in the United States of America. An act to municipal corporation, incorporate the city was passed on May 4, 1852, and incorporation was later approved on March 25, 1854. Oakland is a charter city. Oakland's territory covers what was once a mosaic of California coastal prairie, California coastal terrace prairie, oak woodland, and north coastal scrub.

Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Taxa
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry Augustus Pilsbry
Henry Augustus Pilsbry (7 December 1862 – 26 October 1957) was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial molluscs, terrestrial mollusks, and others. Biography Pilsbry (frequently misspelled ''Pilsbury'') spent his childhood and youth in Iowa. He was called "Harry" Pilsbry then, and developed an early fascination with the limited variety of mollusks he was able to find. He attended the University of Iowa, and received the Bachelor of Science degree there in 1882, but did not immediately find employment in his field of interest. Instead, Henry Pilsbry worked for publishing firms and newspapers for the next several years, but devoted most of his spare time to the ...

Helminthoglypta Walkeriana
The banded dune snail or Morro shoulderband, scientific name ''Helminthoglypta walkeriana'', is a species of air-breathing land snail, a terrestrial animal, terrestrial pulmonate gastropod mollusc in the family Helminthoglyptidae. This species is Endemism, endemic to Morro Bay and the central coast in San Luis Obispo County and Santa Barbara County, in California. Taxonomy At the time the species was divided into two subtaxa (subspecies or varieties): ''H. w. walkeriana'' and *''H. w. morroensis'' The latter was thought to be extinct but was rediscovered. In 2004, it was elevated to species status as ''Helminthoglypta morroensis'' and it inherited the endangered status it had when it was part of ''Helminthoglypta walkeriana''. Both snails together were known as the banded dune snail. Today ''H. walkeriana'' is the Morro shoulderband, and ''H. morroensis'' is the Chorro shoulderband.USFWSMorro Shoulderband and Chorro Shoulderband Five-year Review.September 2006. Conservation T ...

Hemphillia
''Hemphillia'' is a genus of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs. The generic name ''Hemphillia'' is in honor of an American malacologist Henry Hemphill (1830–1914). At least some species of this genus are known as jumping slugs due to their behavior when threatened. At such times, they "jump" by coiling up and straightening out repeatedly in rapid succession. Species Species in the genus ''Hemphillia'' include:COSEWIC (2003). COSEWIC assessment and status report on the dromedary jumping-slug ''Hemphillia dromedarius'' in Canada.
