Domain Eukaryota - Includes all organisms that have both a nucleus and membrane bound organelles in its cells (Hickman et  al., 2012).
Kingdom Animalia - Includes all organisms whose cells do not have cell walls (Hickman et  al., 2012). These organisms are all multicellular (Hickman et  al., 2012).
Phylum Mollusca -One of the largest phyla in the animal kingdom (Hickman et  al., 2012). Most notably defined as being soft bodied coelomates with a radula, mantle, and a muscular foot (Hickman et  al., 2012). They exist in freshwater, marine, and terrestrial habitats (Hickman et  al., 2012).
Gastropoda - A group of mollusks that are defined as having a 180 degree twisting of their visceral mass, called torsion (Hickman et  al., 2012).
Order Pulmonata - Indicates a group of snails whose mantle cavity has been modified into air breathing lungs (Burch and Myers, 2001).
Family Polygyridae - Strictly containing air breathing land snails (Zip Code Zoo, 2012). Snails of this family are distinguished mostly by internal features such as having a ribbed jaw and a single band of muscle used to retract the eyes and pharynx (Zip Code Zoo, 2012).
Genus Neohelix - A subgenus under Triodopsis of which it used to be referred (Encylopedia of Life, 2012).

The species name Neohelix major uses a combination of Latin and Greek words with neo meaning new, helix meaning spiral or curve and major meaning big or great (Wikipedia, 2012). This describes the appearance of a snail from the Neohelix major species. They have a large, smooth, spiral shell.

The common name most used to refer to these snails is Southeastern Whitelip (Encylopedia of Life, 2012). This name is used because it is found in the southeastern areas of the United states (Perez et al., 2008). The second part of that name, Whitelip, comes from the white lip appearance on the edge of its shell as seen below.
