(Encyclopedia of Life, 2012).

Eukarya: This domain consists of animals, fungi, protists, and plants and they are very diverse organisms (Encyclopedia of Life, 2012).

Animalia: This kingdom consists of animals that are multicellular. Most of the animals get their energy from different organisms (Encyclopedia of Life, 2012).

Mollusca: This phylum has molluscs that are invertebrates and they have a mantle. This is a coat of epidermal tissue that borders the body (Encyclopedia of Life, 2012).

Gastropoda: Most organisms in this class have slow locomotor organs and heavy shells. Almost all have one single shell that may be coiled or not (Hickman et. al.,2012).

Stylommatophora: They are mostly terrestrial and some lack shells. The gastropods that have lung or lung-like organs have two sets of invaginable tentacles (Encyclopedia of Life, 2012).

Polygyridae: These snails have reproductive organs and alike shell form within different genera (Pilsbry, 1948). Their jaws are ridged and the muscles are one single band which allows the pharynx and eyes to retract (Encyclopedia of Life, 2012).

Praticolella: The shell of these snails are barely umbilicate and periphery rounded. Their shells are either light cinnamon or  a luminous gray color. their shells can be a whole, uniformed color or have brownish or grayish bands (Pilsbry, 1948).

Praticolella trimatris: This species can be related to similar species in the same genus. With this, we can conclude from the species Praticolella ampla that this species has a small shell and a conic spire of around 4.5 to 5.75 whorls. Also has retractor muscles that are bifurcate or trifurcate pinal (Perez, 2011).
