Oʻahu tree snails , genus Achatinella , form a large genus of colorful , tropical , tree-living , air-breathing , land snails , arboreal pulmonate gastropod mollusks in the family Achatinellidae . This genus of tree snails is endemic to Hawaii , and all extant species are endangered . They were once abundant and were mentioned extensively in Hawaiian folklore and songs , and their shells were used in lei and other ornaments . Many of these arboreal snails are sinistral or left-handed in their spiral shell coiling , whereas most gastropod shells are dextral . ( See the section on chirality in the article gastropod shell . )

Hawaiʻi ( /həˈwaɪi/ ( listen ) hə-WY-ee ; Hawaiian : Hawaiʻi [ həˈvɐjʔi ] ) is a state of the United States of America . It is the only state located in the Pacific Ocean and the only state composed entirely of islands . The state encompasses nearly the entire Hawaiian archipelago , 137 islands spread over 1,500 miles ( 2,400 km ) . The volcanic archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania . At the southeastern end of the archipelago , the eight main islands are , in order from northwest to southeast : Niʻihau , Kauaʻi , Oʻahu , Molokaʻi , Lānaʻi , Kahoʻolawe , Maui , and Hawaiʻi . The last is the largest island in the group ; it is often called the Big Island or Hawaiʻi Island to avoid confusion with the state or archipelago . Hawaiʻi is the 8th-smallest geographically and the 11th-least populous , but the 13th-most densely populated of the 50 states . It is the only state with an Asian American plurality . Hawaii has more than 1.4 million permanent residents , along with many visitors and U.S. military personnel . The state capital and largest city is Honolulu on the island of Oʻahu . The state 's ocean coastline is about 750 miles ( 1,210 km ) long , the fourth longest in the U.S. , after the coastlines of Alaska , Florida , and California . Hawaii is the most recent state to join the union , on August 21 , 1959 .
Anguispira picta , common names painted snake-coiled forest snail and painted tigersnail , is a rare species of air-breathing land snail , a terrestrial pulmonate gastropod mollusk in the family Discidae , the disc snails . This species is native to Tennessee in the United States , where it is known only from Franklin County . It may possibly also occur just over the border in Alabama . It is a federally listed threatened species of the United States . This snail was first discovered in 1906 . It was once treated as a subspecies of the more common Anguispira cumberlandiana . It is now a species in its own right . The snail is about 2 centimeters wide and 1 high . Its shape is a depressed dome . The shell has six whorls which are whitish with brownish blotches . The juvenile has a translucent and brightly colored shell . This snail was long thought to be endemic to one cove on the edge of the Cumberland Plateau , near the town of Sherwood , Tennessee .

Illinois ( /ˌɪləˈnɔɪ/ ( listen ) IL-ə-NOY ) is a state in the Midwestern and Great Lakes Regions of the United States . It has the fifth largest gross domestic product ( GDP ) , the sixth largest population , and the 25th largest land area of all U.S. states . Illinois has been noted as a microcosm of the entire United States . With Chicago in northeastern Illinois , small industrial cities and immense agricultural productivity in the north and center of the state , and natural resources such as coal , timber , and petroleum in the south , Illinois has a diverse economic base , and is a major transportation hub . Chicagoland , Chicago 's metropolitan area , encompasses over 65% of the state 's population . The Port of Chicago connects the state to international ports via two main routes : from the Great Lakes , via the Saint Lawrence Seaway , to the Atlantic Ocean and from the Great Lakes to the Mississippi River , via the Illinois Waterway to the Illinois River . The Mississippi River , the Ohio River , and the Wabash River form parts of the boundaries of Illinois . For decades , Chicago 's O'Hare International Airport has been ranked as one of the world 's busiest airports . Illinois has long had a reputation as a bellwether both in social and cultural terms and , through the 1980s , in politics . The capital of Illinois is Springfield , which is located in the central part of the state . Although today Illinois 's largest population center is in its northeast , the state 's European population grew first in the west as the French settled lands near the Mississippi River , when the region was known as Illinois Country and was part of New France . Following the American Revolutionary War , American settlers began arriving from Kentucky in the 1780s via the Ohio River , and the population grew from south to north .

Arkansas ( /ˈɑːrkənsɔː/ AR-kən-saw ) [ c ] is a state in the south central region of the United States , home to more than three million people as of 2018 . Its name is from the Osage language , of Siouan derivation ; it denoted their related kin , the Quapaw people . The state 's diverse geography ranges from the mountainous regions of the Ozark and the Ouachita Mountains , which make up the U.S . Interior Highlands , to the densely forested land in the south known as the Arkansas Timberlands , to the eastern lowlands along the Mississippi River and the Arkansas Delta . Arkansas is the 29th largest by area and the 33rd most populous of the 50 United States . The capital and most populous city is Little Rock , located in the central portion of the state , a hub for transportation , business , culture , and government . The northwestern corner of the state , such as the Fayetteville-Springdale-Rogers Metropolitan Area and Fort Smith metropolitan area , is a population , education , and economic center . The largest city in the state 's eastern part is Jonesboro . The largest city in the state 's southeastern part is Pine Bluff . The Territory of Arkansas was admitted to the Union as the 25th state on June 15 , 1836 . Much of the Delta had been developed for cotton plantations , and the state landowners largely depended on enslaved African Americans as workers . In 1861 , Arkansas seceded from the United States and joined the Confederate States of America during the Civil War .
The Chittenango ovate amber snail , scientific name Novisuccinea chittenangoensis , is a species of small air-breathing land snail in the family Succineidae , the amber snails . This species was discovered in 1905 , and was reported three years later as a subspecies of the oval ambersnail , Succinea ovalis . Several taxonomic reviews took place in the subsequent decades until the end of the 1980s , when the Chittenango ovate amber snail was finally judged to be a distinct species Novisuccinea chittenangoensis , based on chemical and morphological data . The Chittenango ovate amber snail is endemic to the Chittenango area of Madison County , New York , United States . There is only one population of this species at Chittenango Falls State Park in central New York , even though it was believed to have a broader range previously ; based on fossil records , some authors argue that the distribution of this species may have been much wider in the past . In opposition to this , other authors argue that it is impossible to identify this species based on fossil records , because they only allow for examination of shell features . Shell features of species in this particular family of snails are usually not very distinctive . Novisuccinea chittenangoensis has a small ( an average of 20.9 mm in length in adult individuals ) , delicate , ovate shell of 3¼ whorls , with deep sutures . The shell is almost translucent , and varies in color from a chalky pale yellow to white , with a glossy surface . Several internal organs of the animal can be distinguished through the shell 's outer surface . The visible soft parts of the animal are of a pale subtranslucent yellow color , with different markings during distinct stages of development . Studies on the ecology of the Chittenango ovate amber snail are fairly recent .

New York is a state located in the Northeastern United States . New York was one of the original thirteen colonies that formed the United States . With an estimated 19.45 million residents in 2019 , it is the fourth most populous state . In order to distinguish the state from its city with the same name , it is commonly referred to as New York State ( NYS ) . The state 's most populous city , New York City , makes up over 40% of the state 's population . Two-thirds of the state 's population lives in the New York metropolitan area , and nearly 40% lives on Long Island . The state and city were both named for the 17th-century Duke of York , the future King James II of England . With an estimated population of 8.39 million in 2018 , New York City is the most populous city in the United States and the premier gateway for legal immigration to the United States .

Orthalicus reses , common name the Stock Island , Florida tree snail , is a species of large tropical air-breathing land snail , a tree snail , a terrestrial pulmonate gastropod mollusk in the family Orthalicidae . It was first described in 1830 by the American naturalist Thomas Say . The holotype , a specimen probably collected in Key West , was subsequently lost . Over a hundred years later , in 1946 , the American biologist Henry Augustus Pilsbry redescribed the species using a specimen from Stock Island . Orthalicus reses has two subspecies , O. reses reses and O. reses nosodryas . The validity of these two taxa is still being discussed , but some experts argue that considering them as independent units may be important for management purposes . The Stock Island tree snail has a large conical shell ( 45-55 mm in length ) with variable thickness , generally lighter and more translucent than other species of Orthalicus . It is colored white to buff , with weakly developed spiral bands and several flame-like , purple-brown axial stripes . The subspecies O. reses reses and O. reses nosodryas can be distinguished from one another based on the different color patterns of the apical whorl , columella , and parietal callus . The nominate subspecies Orthalicus reses reses is threatened ; it lives on trees in hardwood hammocks habitat in Southern Florida , USA , specifically the Florida Keys .

The Kanab ambersnail , scientific name Oxyloma haydeni kanabense or Oxyloma kanabense , is a critically endangered subspecies or species of small , air-breathing land snail , a terrestrial pulmonate gastropod mollusc in the family Succineidae , the amber snails . The common name of the amber snails is based on the shell , which is translucent and when empty usually resembles the color of amber . This species is endemic to the United States , specifically the state of Arizona and Utah , where it was first collected in the early 20th century . It has been listed as endangered on the United States Fish and Wildlife Service list of endangered species since 8 August 1991 . [ citation needed ] This snail lives in wetlands , springs , and seeps , and only two of its natural habitats are known to exist : Three Lakes , a meadow near Kanab , Utah , and Vasey 's Paradise , a springs along the Colorado River within Grand Canyon National Park . In its natural habitat it is rather polyphagous , feeding mainly on bacteria , plants and fungi . It reproduces during the summer . Now considered a critically endangered species on the IUCN Red List of Threatened Species due to a series of factors ( including anthropic influence ) , the Kanab ambersnail has been reintroduced to three springs above the historic high water level along the Colorado River .

Virginia ( /vərˈdʒɪniə/ ( listen ) ) , officially the Commonwealth of Virginia , is a state in the Southeastern and Mid-Atlantic regions of the United States located between the Atlantic Coast and the Appalachian Mountains . The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay , which provide habitat for much of its flora and fauna . The capital of the Commonwealth is Richmond ; Virginia Beach is the most populous city , and Fairfax County is the most populous political subdivision . The Commonwealth 's estimated population as of 2018 [ update ] is over 8.5 million . The area 's history begins with several indigenous groups , including the Powhatan . In 1607 the London Company established the Colony of Virginia as the first permanent English colony in the New World . Virginia 's state nickname , the Old Dominion , is a reference to this status . Slave labor and the land acquired from displaced Native American tribes each played a significant role in the colony 's early politics and plantation economy . Virginia was one of the 13 Colonies in the American Revolution . In the American Civil War , Virginia 's Secession Convention resolved to join the Confederacy , and Virginia 's First Wheeling Convention resolved to remain in the Union ; that led to the creation of West Virginia . Although the Commonwealth was under one-party rule for nearly a century following Reconstruction , both major national parties are competitive in modern Virginia . The Virginia General Assembly is the oldest continuous law-making body in the New World .
The flat-spired three-toothed snail ( Triodopsis platysayoides ) - also known as the Cheat three-toothed snail after the Cheat River in West Virginia - is a species of air-breathing land snail , a terrestrial pulmonate gastropod mollusk in the family Polygyridae .
West Virginia ( /vərˈdʒɪniə/ ( listen ) ) is a state located in the Appalachian region of the Southern United States , and is also considered to be a part of the Mid-Atlantic Southeast Region . It is bordered by Pennsylvania to the north , Maryland to the east and northeast , Virginia to the southeast , Kentucky to the southwest , and Ohio to the northwest . West Virginia is the 41st largest state by area , and is ranked 38th in population . The capital and largest city is Charleston . West Virginia became a state following the Wheeling Conventions of 1861 , at the start of the American Civil War . Delegates from the Unionist counties of northwestern Virginia decided to break away from Virginia , which also included secessionist counties in the new state . West Virginia was admitted to the Union on June 20 , 1863 , and was a key border state during the war . It was the only state to form by separating from a Confederate state , the first to separate from any state since Maine separated from Massachusetts , and was one of two states admitted to the Union during the American Civil War ( the other being Nevada ) . While a portion of its residents held slaves , most of the residents were yeoman farmers , and the delegates provided for gradual abolition of slavery in the new state Constitution . The Census Bureau and the Association of American Geographers classify West Virginia as part of the Southern United States . However , the Bureau of Labor Statistics classifies the state as a part of the Mid-Atlantic region . The northern panhandle extends adjacent to Pennsylvania and Ohio , with the West Virginia cities of Wheeling and Weirton just across the border from the Pittsburgh metropolitan area , while Bluefield is less than 70 miles ( 110 km ) from North Carolina .
