Malacology
Malacology is the study of mollusks. This includes animals like octopus, snails, slugs, and clams. It is the second largest phylum of animals, making them one of the most successful groups on the planet. There are over 80,000 described species of mollusks with many more left to be discovered. Mullusca is composed of 8 recognized classes including Cephalopoda, Gastropoda, Polyplacophora, Scaphapoda, Monoplacophorans, the Aplacophorans, Caudofoveata and Solenogastres, and Bivalvia.

Etymology
Original Description:
Shell imperforate, thin, reddish-horn color; densely hirsute with very fine, short hairs. Whorls 5, those of the spire convex with a well-impressed suture; the body whorl with the periphery situated high, very convex below, impressed in the umbilical region, abruptly deflected at the aperture and contracted behind the lip. Aperture transverse, narrow, widening anteriorly; parietal tooth large, erect, parallel to the lip in its lower half, then curving outward and in the upper third inward terminating in a hook which passes under the lip between the notch and the lip tooth, outer end connected with the peristome by a low ridge; outer lip reflected back against the body-whorl but free its entire length; lip notch stretched out so that it forms a regular curve in the lip for over half its length with the edge raised from the lip; beyond the notch the lip sweeps around the inner end of the parietal tooth and then forms a small tooth above; fulcrum medium.
Largest shell (type), diam. 7 ΒΌ , alt. 5 mm., smallest 6 x 4, average 7 x 5 mm.
The character of the lip at once differentiates this species from all others of the group; it is apparently closest to P. brevipila.
