Domain: Eukarya includes all organisms that have a membrane-bound nucleus
(Encyclopedia Of Life).

Kingdom: Animalia consists of all multicellular, eukaryotic heterotrophs. 

Phylum: Mollusca contains some of the most well-known invertebrates including snails, slugs, clams, mussels and octopuses all having the mantle, an epidermal tissue layer that surrounds the body (Encyclopedia of Life).

Class: Gastropoda is characterized by torsion, which is the rotation of the visceral mass and mantle on the foot.  As a result, the mantle cavity has been shifted to the anterior body over the head and the mouth (Encyclopedia of Life).

Order: Stylommatophora are pulmonate gastropods with two pairs of retractable tentacles (Encyclopedia of Life).

Family: Polygyridae are air-breathing land snails, terrestrial pulmonate gastropod mollusks with ribbed jaws and lacking the dart apparatus, a structure used for courtship (Encyclopedia of Life).

Genus: Linisa are classified by the structures located around the peristome, the margin around the opening of the shell (Pratt 1981).  The snails in the genus Linisa lack the callus extension and  the parietal lamella extends to or near the columellar insertion of peristome. (Pratt, 1981).  

Species: Linisa tamaulipasensis is a species of snails found within the eastern part of the Edwards Plateau (Pratt, 1981).
