Pleurocera is the type genus of that family.

Distribution

All members of the genus Pleurocera are native to eastern North America.[2]

Description

All of the species in this genus have thick-walled high-spired shells, and some attain a length of over 4 cm. The shape of the shell is elongate-conic or cylindrical.[2] The sculpture of the shell is often carinate or costate.[2] The shell of larger species sometimes develops sculpturing and a small siphonal canal or siphonal notch at the base of the aperture.[2]

Opercula are paucispiral and corneous, but may be vestigial in some species, not completely closing the aperture.

The soft parts of the animal usually have a gray or brown coloration, commonly speckled with orange. The similar genus Juga has a seminal receptacle, but Pleurocera has no seminal receptacle.[2]
