Rich Mountain Slitmouth
Rich Mountain slitmouth or Pilsbry's narrow-apertured land snail, scientific name ''Stenotrema pilsbryi'', is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae. This species is endemic to Ouachita Mountains of the United States. Description The Rich Mountain slitmouth occurs in a very small range in southeast Oklahoma and southwest Arkansas Arkansas ( ) is a landlocked state in the South Central United States. It is bordered by Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, and Texas and Oklahoma to the west. Its name is from the Osage .... Its appearance is atypical, as it has protrusions which cover the shell. These protrusions have the effect of making the snail look hairy.

James Henry Ferriss
James Henry Ferriss (1849-1926) was an American politician and amateur conchologist. According to Henry Augustus Pilsbry, Ferriss was "the fore-most of American landshell collectors... as a collector he has probably never been surpassed." Biography James H. Ferriss was born November 18, 1849, in Kendall Township, Kendall County, Illinois, Ferriss moved to southeastern Kansas in 1869 to stake a claim as a farmer, freighter, and storekeeper. He returned to Illinois in 1872 to work as a reporter and editor of several newspapers in Joliet, Illinois. A fiery prohibitionist, he purchased and edited the ''Joliet News'' in 1877 but was jailed that year for an editorial which offended a local political boss. He moved to Maine after the incident, but returned in 1882 to edit the ''Joliet News'' until 1915. He was elected National Chairman of the People's Party in 1904. Ferriss died on March 17, 1926. He was 76 years old at the time of his death. Footnotes Works * * "The Populist Vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ouachita Mountains
The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America. The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas. Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands. The highest natural point is Mount Magazine at . The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions. Etymology Louis R. Harlan claimed that "Ouachita" is composed of the Choctaw words ''ouac'' for "buffalo" and ''chito'' for "large", together meaning "country of large buffa ...

Gastropods Described In 1900
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

Rich Mountain (Arkansas–Oklahoma)
Rich Mountain is the second highest point of the U.S. Interior Highlands and Ouachita Mountains, and in the U.S. state of Arkansas; it is also the site of Queen Wilhelmina State Park. Rich Mountain is a long, generally east–west-trending ridge composed of hard sandstone. It is located just outside of Mena, Arkansas and is intersected by the Arkansas-Oklahoma border. Atop its summit is the Rich Mountain Lookout Tower, which is approximately east-southeast of the Queen Wilhelmina Lodge. Arkansas State Highway 88 and Oklahoma State Highway 1, collectively known as the Talimena Scenic Drive, traverse the entire top of Rich Mountain and provide excellent vistas of the surrounding Ouachita Mountains The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
