Volema pyrum
Volema pyrum is a species of sea snail, a marine gastropod mollusk in the family Melongenidae, the crown conches and their allies. Nomenclature
Abbott & Dance (1986: 176) treated Gmelin's name as preoccupied by Linnaeus, but Gmelin named his species as a Buccinum, not a Murex. Description
The size of the adult shell varies between 40 mm and 52 mm. The shell is cream-colored (with top of the spire being darker) and somewhat pear-shaped, and is mostly smooth with faint ridges on the lower half of the body whorl. The shell of Volema paradisiaca lacks any knobs or spines. Distribution
This species occurs in the Indian Ocean off Madagascar, Mozambique and Tanzania; in the Singapore Strait. References
