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.

Original Description:
Shell subglobose, pale yellow horn colour, polished ; body whorl, pellucid, yellowish- white, opake beneath near the aperture ; volutions rather more than six, all excepting the apicial one wrinkled across ; spire convex, a little elevated; umbilicus very small ; suture not deeply impressed ; labrum not reflected. Inhabits Missouri. Greatest length 3-10. Oblique length less than 9-20. Transverse diameter less than 11-20. Approaches nearest to H. glaphyra, but is readily distinguished by the greater convexity of the spire, and the smaller umbilicus. Rather common. In Lister's conch, on pi. 81, fig. 82, a shell is represented which may be intended for this species.
