Gemophos viverratus is a species of sea snail, a marine gastropod mollusk in the family Pisaniidae.
The edge of the angle in young specimens, is more prominent, and bordered by a row of pretty apparent tubercles, which disappear with age.
These striae are interrupted by elongated white or reddish spots, often presenting grayish flammules upon the upper whorls.
The outer lip is straight, thin, sharp, lightly striated at its inner edge with brown lines.
[2] This species occurs in the Atlantic Ocean from Mauritania to Angola; off the Cape Verdes and the Canary Islands.
